They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.Imipenem: Semisynthetic thienamycin that has a wide spectrum of antibacterial activity against gram-negative and gram-positive aerobic and anaerobic bacteria, including many multiresistant strains.

It has been proposed for infections with gram-negative and gram-positive organisms, GONORRHEA, and HAEMOPHILUS.Cefotiam: One of the CEPHALOSPORINS that has a broad spectrum of activity against both gram-positive and gram-negative microorganisms.Thienamycins: Beta-lactam antibiotics that differ from PENICILLINS in having the thiazolidine sulfur atom replaced by carbon, the sulfur then becoming the first atom in the side chain. They are unstable chemically, but have a very broad antibacterial spectrum. Thienamycin and its more stable derivatives are proposed for use in combinations with enzyme inhibitors.Penicillin-Binding Proteins: Bacterial proteins that share the property of binding irreversibly to PENICILLINS and other ANTIBACTERIAL AGENTS derived from LACTAMS.

The acid is a suicide inhibitor of bacterial beta-lactamase enzymes from Streptomyces clavuligerus. Administered alone, it has only weak antibacterial activity against most organisms, but given in combination with other beta-lactam antibiotics it prevents antibiotic inactivation by microbial lactamase.Drug Resistance, Bacterial: The ability of bacteria to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).Meningitis: Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER.

Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.Ciprofloxacin: A broad-spectrum antimicrobial carboxyfluoroquinoline.Bacterial Infections: Infections by bacteria, general or unspecified.Muramoylpentapeptide Carboxypeptidase: Enzyme which catalyzes the peptide cross-linking of nascent CELL WALL; PEPTIDOGLYCAN.Empiricism: One of the principal schools of medical philosophy in ancient Greece and Rome. It developed in Alexandria between 270 and 220 B.C., the only one to have any success in reviving the essentials of the Hippocratic concept. The Empiricists declared that the search for ultimate causes of phenomena was vain, but they were active in endeavoring to discover immediate causes. The "tripod of the Empirics" was their own chance observations (experience), learning obtained from contemporaries and predecessors (experience of others), and, in the case of new diseases, the formation of conclusions from other diseases which they resembled (analogy). Empiricism enjoyed sporadic continuing popularity in later centuries up to the nineteenth. (From Castiglioni, A History of Medicine, 2d ed, p186; Dr. James H. Cassedy, NLM History of Medicine Division)Serum Bactericidal Test: Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in BACTERIAL ENDOCARDITIS; OSTEOMYELITIS and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test. This test needs to be distinguished from testing of the naturally occurring BLOOD BACTERICIDAL ACTIVITY.Pneumococcal Infections: Infections with bacteria of the species STREPTOCOCCUS PNEUMONIAE.Clavulanic Acids: Acids, salts, and derivatives of clavulanic acid (C8H9O5N). They consist of those beta-lactam compounds that differ from penicillin in having the sulfur of the thiazolidine ring replaced by an oxygen. They have limited antibacterial action, but block bacterial beta-lactamase irreversibly, so that similar antibiotics are not broken down by the bacterial enzymes and therefore can exert their antibacterial effects.Tobramycin: An aminoglycoside, broad-spectrum antibiotic produced by Streptomyces tenebrarius. It is effective against gram-negative bacteria, especially the PSEUDOMONAS species. It is a 10% component of the antibiotic complex, NEBRAMYCIN, produced by the same species.Penicillanic Acid: A building block of penicillin, devoid of significant antibacterial activity.

There are ribosomal and non-ribosomal peptidyltransferases.Klebsiella: A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria whose organisms arrange singly, in pairs, or short chains. This genus is commonly found in the intestinal tract and is an opportunistic pathogen that can give rise to bacteremia, pneumonia, urinary tract and several other types of human infection.Meningitis, Pneumococcal: An acute purulent infection of the meninges and subarachnoid space caused by Streptococcus pneumoniae, most prevalent in children and adults over the age of 60. This illness may be associated with OTITIS MEDIA; MASTOIDITIS; SINUSITIS; RESPIRATORY TRACT INFECTIONS; sickle cell disease (ANEMIA, SICKLE CELL); skull fractures; and other disorders. Clinical manifestations include FEVER; HEADACHE; neck stiffness; and somnolence followed by SEIZURES; focal neurologic deficits (notably DEAFNESS); and COMA. (From Miller et al., Merritt's Textbook of Neurology, 9th ed, p111)Drug Resistance, Multiple, Bacterial: The ability of bacteria to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).Isoelectric Focusing: Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point.Fleroxacin: A broad-spectrum antimicrobial fluoroquinolone. The drug strongly inhibits the DNA-supercoiling activity of DNA GYRASE.Anti-Infective Agents: Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.Penicillin G: A penicillin derivative commonly used in the form of its sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria and against gram-negative cocci. It has also been used as an experimental convulsant because of its actions on GAMMA-AMINOBUTYRIC ACID mediated synaptic transmission.Amikacin: A broad-spectrum antibiotic derived from KANAMYCIN. It is reno- and oto-toxic like the other aminoglycoside antibiotics.Gentamicins: A complex of closely related aminoglycosides obtained from MICROMONOSPORA purpurea and related species.

Interpretation of middle ear fluid concentrations of antibiotics: comparison between ceftibuten, cefixime and azithromycin. (1/764)

AIMS: The aim of this study was to determine the potential influence of variables such as the cell content in the fluid, and serum levels, on the concentrations of ceftibuten, cefixime and azithromycin in the middle ear fluid of patients suffering from acute otitis media. METHODS: This randomized, open study compared the penetration of ceftibuten (9 mg kg(-1) 18 patients), cefixime (8 mg kg(-1), 16 patients) and azithromycin (10 mg kg(-1) 16 patients) into the intracellular and extracellular compartments of middle ear fluid of 50 paediatric patients (aged 8-14 years) with acute otitis media. Middle ear fluid was extracted by tympanocentesis 4, 12 and 24 h after dosing and divided into two fractions: with cells (as collected) (C+) and cell-free (C-). Antibiotics were assayed in C+ and C- samples by h.p.l.c. RESULTS: Ceftibuten achieved greater penetration into middle ear fluid than cefixime and azithromycin. Higher concentrations of ceftibuten (CTB) and cefixime (CFX) were found in the C- fraction (CTB: 4h 13.3+/-1.86; 12h 4.7+/-1.18; 24h 0.5+/-0.2. CFX: 4h 3.2+/-1.4; 12h 1.5+/-0.5; 24h>(0.1 mgl(-1)) than in the C+ fraction (CTB:4 h 8.4+/-4.3; 12 h 2.88+/-1.19; 24 h 0.3+/-0.27. CFX: 4 h 1.2+/-0.6; 12 h 0.8+/-0.2; 24 h>0.1 mg l(-1)) at the each time point, while the opposite was true for azithromycin (C-: 4 h 0.11+/-0.04; 12 h 0.12+/-0.08; 24 h 0.23+/-0.12. C+: 4 h 0.38+/-0.24; 12 h 0.9+/-0.03; 24 h 1.05+/-0.3 mg l(-1)). CONCLUSIONS: This study demonstrates that the penetration of antibiotics into the middle ear fluid is influenced by its serum concentrations as well as by the cell content in the fluid. Ceftibuten achieved higher middle ear fluid concentrations than cefixime in C+ and C- fractions at all time points. Both ceftibuten and cefixime concentrations are negatively influenced by the cell content in the fluid. In contrast the concentration of azithromycin to the middle ear fluid is positively influenced by the cell content in the fluid.  (+info)

Glycosyltransferase domain of penicillin-binding protein 2a from Streptococcus pneumoniae is membrane associated. (2/764)

Penicillin-binding proteins (PBPs) are bacterial cytoplasmic membrane proteins that catalyze the final steps of the peptidoglycan synthesis. Resistance to beta-lactams in Streptococcus pneumoniae is caused by low-affinity PBPs. S. pneumoniae PBP 2a belongs to the class A high-molecular-mass PBPs having both glycosyltransferase (GT) and transpeptide (TP) activities. Structural and functional studies of both domains are required to unravel the mechanisms of resistance, a prerequisite for the development of novel antibiotics. The extracellular region of S. pneumoniae PBP 2a has been expressed (PBP 2a*) in Escherichia coli as a glutathione S-transferase fusion protein. The acylation kinetic parameters of PBP 2a* for beta-lactams were determined by stopped-flow fluorometry. The acylation efficiency toward benzylpenicillin was much lower than that toward cefotaxime, a result suggesting that PBP 2a participates in resistance to cefotaxime and other beta-lactams, but not in resistance to benzylpenicillin. The TP domain was purified following limited proteolysis. PBP 2a* required detergents for solubility and interacted with lipid vesicles, while the TP domain was water soluble. We propose that PBP 2a* interacts with the cytoplasmic membrane in a region distinct from its transmembrane anchor region, which is located between Lys 78 and Ser 156 of the GT domain.  (+info)

Single-dose oral ciprofloxacin compared with cefotaxime and placebo for prophylaxis during transurethral surgery. (3/764)

To determine the efficacy and safety of single-dose oral ciprofloxacin prophylaxis for the prevention of post-operative bacteriuria following transurethral resection of the prostate or bladder tumour, a prospective, randomized, double-blind, placebo-controlled trial was conducted. Five hundred and eighteen patients were randomized in a 2:2:1 ratio to receive ciprofloxacin 500 mg, cefotaxime 1 g or placebo 30-90 min before surgery. Of the 368 efficacy-evaluable patients, five (3.3%) ciprofloxacin, seven (4.8%) cefotaxime and five (7.0%) placebo recipients had post-operative bacteriuria (> or = 10(4) cfu/mL) during post-operative days 2-15. Five (3.4%) ciprofloxacin, five (3.4%) cefotaxime and one (2.4%) placebo recipients were considered clinical failures, of whom one, two and one patients, respectively, had concomitant bacteriuria. Drug-related adverse events were reported in six of 204 (3%) ciprofloxacin, 12 of 197 (6%) cefotaxime and one of 101 (1%) placebo patients. The observed rates of post-operative bacteriuria suggest that a single 500 mg dose of ciprofloxacin is suitable prophylaxis for transurethral surgery.  (+info)

Dissemination of a chloramphenicol- and tetracycline-resistant but penicillin-susceptible invasive clone of serotype 5 Streptococcus pneumoniae in Colombia. (4/764)

A national surveillance conducted in Colombia between 1994 and 1996 identified serotype 5 Streptococcus pneumoniae as the second most frequent cause of invasive disease in children younger than 5 years of age. All 43 serotype 5 isolates collected during this period were shown to be susceptible to penicillin, erythromycin, cefotaxime, and vancomycin, but most (38 of 43, or 88%) were highly resistant to chloramphenicol. In order to clarify a possible genetic relatedness among these isolates, additional microbiological and molecular characterizations were performed. Most (40 of 43, or 93%) of the isolates were found to be resistant to tetracycline. Pulsed-field gel electrophoresis (PFGE) patterns of chromosomal DNAs revealed that all the 43 isolates were closely related and that 38 of the 43 isolates were representatives of a "Colombian clone" of S. pneumoniae isolates which were recovered throughout the 3-year surveillance period from patients in 13 hospitals located in five Colombian cities. Isolates belonging to this Colombian clone were resistant to chloramphenicol and tetracycline, hybridized with the cat and tetM DNA probes in the same 340-kb SmaI fragment, and had identical PFGE patterns after both SmaI and ApaI digestions.  (+info)

In-vitro activity of 29 antimicrobial agents against penicillin-resistant and -intermediate isolates of Streptococcus pneumoniae. (5/764)

Antibiotic resistance among isolates of Streptococcus pneumoniae is increasing worldwide. Optimal therapy, though unknown, should be guided by in-vitro susceptibility testing. Currently, vancomycin is the only approved antibiotic that is universally active against multiresistant S. pneumoniae. In-vitro activities were determined for 29 antimicrobial agents against 22 penicillin-intermediate S. pneumoniae (PISP) and 16 penicillin-resistant S. pneumoniae (PRSP) isolates. MICs were determined in cation-adjusted Mueller-Hinton broth with 3% lysed horse blood in microtitre trays. Antimicrobial classes tested included cephalosporins, penicillin, aminopenicillins, macrolides, quinolones, carbapenems and other antimicrobial agents. Among the classes of antimicrobial agents tested, wide differences in susceptibility were demonstrated for both PISP and PRSP. Of the cephalosporins, ceftriaxone and cefotaxime demonstrated the best in-vitro activity for both PISP and PRSP. Of the quinolones, clinafloxacin and trovafloxacin showed the greatest in-vitro activity. Rifampicin and teicoplanin demonstrated excellent in-vitro activity. Promising in-vitro results of newer agents, such as quinupristin/dalfopristin, ramoplanin, teicoplanin and linezolid may justify further evaluation of these agents in clinical trials.  (+info)

Serum bactericidal activity of levofloxacin against Streptococcus pneumoniae. (6/764)

The objective of this study was to determine the serum bactericidal activity (SBA) of levofloxacin against Streptococcus pneumoniae strains with various degrees of susceptibility to penicillin and cefotaxime. Serum samples of volunteers (n = 12) who had received levofloxacin 500 mg as a single po dose were provided in blinded fashion. SBA was determined, using the microdilution method, in Todd-Hewitt broth supplemented with lysed horse blood inoculated with an overnight culture diluted to yield a final concentration of approximately 10(5) cfu/mL. The serum bactericidal titre was defined as the highest dilution of serum showing no growth (> 99.9% reduction of inoculum). The duration of SBA ranged from 0.75 to 6.3 h (mean 3.85 h), and was independent of the susceptibility of the strains to penicillin and cefotaxime. In conclusion, a single po dose of 500 mg levofloxacin achieved serum concentrations which were bactericidal against penicillin-resistant S. pneumoniae for a mean period of 3.85 h.  (+info)

Effect of intravenous albumin on renal impairment and mortality in patients with cirrhosis and spontaneous bacterial peritonitis. (7/764)

BACKGROUND: In patients with cirrhosis and spontaneous bacterial peritonitis, renal function frequently becomes impaired. This impairment is probably related to a reduction in effective arterial blood volume and is associated with a high mortality rate. We conducted a study to determine whether plasma volume expansion with intravenous albumin prevents renal impairment and reduces mortality in these patients. METHODS: We randomly assigned 126 patients with cirrhosis and spontaneous bacterial peritonitis to treatment with intravenous cefotaxime (63 patients) or cefotaxime and intravenous albumin (63 patients). Cefotaxime was given daily in dosages that varied according to the serum creatinine level, and albumin was given at a dose of 1.5 g per kilogram of body weight at the time of diagnosis, followed by 1 g per kilogram on day 3. Renal impairment was defined as nonreversible deterioration of renal function during hospitalization. RESULTS: The infection resolved in 59 patients in the cefotaxime group (94 percent) and 62 in the cefotaxime-plus-albumin group (98 percent) (P=0.36). Renal impairment developed in 21 patients in the cefotaxime group (33 percent) and 6 in the cefotaxime-plus-albumin group (10 percent) (P=0.002). Eighteen patients (29 percent) in the cefotaxime group died in the hospital, as compared with 6 (10 percent) in the cefotaxime-plus-albumin group (P=0.01); at three months, the mortality rates were 41 percent (a total of 26 deaths) and 22 percent (a total of 14 deaths), respectively (P=0.03). Patients treated with cefotaxime had higher levels of plasma renin activity than those treated with cefotaxime and albumin; patients with renal impairment had the highest values. CONCLUSIONS: In patients with cirrhosis and spontaneous bacterial peritonitis, treatment with intravenous albumin in addition to an antibiotic reduces the incidence of renal impairment and death in comparison with treatment with an antibiotic alone.  (+info)

Reduction in the incidence of methicillin-resistant Staphylococcus aureus and ceftazidime-resistant Klebsiella pneumoniae following changes in a hospital antibiotic formulary. (8/764)

In 1995, changes in our hospital formulary were made to limit an outbreak of vancomycin-resistant enterococci and resulted in decreased usage of cephalosporins, imipenem, clindamycin, and vancomycin and increased usage of beta-lactam/beta-lactamase-inhibitor antibiotics. In this report, the effect of this formulary change on other resistant pathogens is described. Following the formulary change, there was a reduction in the monthly number (mean +/- SD) of patients with methicillin-resistant Staphylococcus aureus (from 21.9 +/- 8.1 to 17.2 +/- 7.2 patients/1,000 discharges; P = .03) and ceftazidime-resistant Klebsiella pneumoniae (from 8.6 +/- 4.3 to 5.7 +/- 4.0 patients/1,000 discharges; P = .02). However, there was an increase in the number of patients with cultures positive for cefotaxime-resistant Acinetobacter species (from 2.4 +/- 2.2 to 5.4 +/- 4.0 patients/1,000 discharges; P = .02). Altering an antibiotic formulary may be a possible mechanism to contain the spread of selected resistant pathogens. However, close surveillance is needed to detect the emergence of other resistant pathogens.  (+info)

TY - JOUR. T1 - High-pressure liquid chromatographic assay of cefotaxime and desacetylcefotaxime in human myometrium. AU - Bawdon, R. E.. AU - Novick, W. J.. AU - Hemsell, D. L.. AU - Welch, W. D.. PY - 1984. Y1 - 1984. N2 - An analytic high-pressure liquid chromatographic (HPLC) procedure for the assay of desacetylcefotaxime and cefotaxime in gynecologic tissue was developed. Normal individuals undergoing elective hysterectomy were subjects in this study. Blood and myometrium were removed up to four hours after a l-g intramuscular dose of cefotaxime. Since cefotaxime is unstable in homogenized tissue at room temperature, the specimens must be maintained at 4 degree C during homogenization and extraction. Mean serum desacetylcefotaxime and cefotaxime levels were 3. 2 plus or minus 2. 0 mu g/ml and 6. 8 plus or minus 4. 4 mu g/ml, respectively. The mean myometrium concentrations of desacetylcefotaxime and cefotaxime were 8. 4 plus or minus 10. 0 mu g/g and 6. 3 plus or minus 8. 9 mu g/g, ...

Four ceftazidime-resistant Escherichia coli strains were isolated from elderly nursing home patients in a New York hospital during 1993. Strains MCQ-2, MCQ-3, and MCQ-4 were determined to be identical by pulsed-field gel electrophoresis and plasmid profiles, whereas strain MCQ-1 was unique. Strain MCQ-1 was determined to produce a TEM-10 beta-lactamase. Strains MCQ-2, MCQ-3, and MCQ-4 were also noted to be resistant to cefotaxime. These three strains produced two beta-lactamases with pIs of 5.4 (TEM-1) and 7.6. beta-Lactamase assays revealed that the pI 7.6 enzyme hydrolyzed cefotaxime faster (at a relative hydrolysis rate of 30% compared with that of benzylpenicillin) than either ceftazidime or aztreonam (relative hydrolysis rates of 13 and 3.3%, respectively). Nucleotide sequencing of the gene encoding the pI 7.6 beta-lactamase from strain MCQ-3 revealed a blaSHV-type gene differing from the gene encoding SHV-1 at four nucleotides which resulted in amino acid substitutions: phenylalanine for ...
This randomised prospective non-blinded study compared the pharmacokinetics, pharmacodynamics, antibiotic resistance and clinical efficacy of continuous vs intermittent administration of cefotaxime in 93 patients with chronic obstructive pulmonary disease (COPD) requiring hospitalisation for moderate to severe community acquired exacerbations (GOLD stages 2-4). Forty-seven patients received 2 g of cefotaxime as a continuous infusion over 24 h plus a loading dose of 1 g, while 46 patients received the drug intermittently (1 g three times daily). The mean duration of treatment was 10 days.. The most commonly isolated pathogens were Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis. Clinical cure was achieved in 37/40 (93%) with continuous infusion and 40/43 (93%) with intermittent administration (p = 0.93). No patients in the continuous group had antibiotic concentrations lower than minimal inhibitory concentration (MIC) compared with 40% in the intermittent group. Samples ...

Recently, several reports have described ESBLs that do not belong to either the TEM or the SHV family and that are more active against cefotaxime than ceftazidime but that are inhibited by clavulanic acid (3, 5-7, 13-15, 20, 29, 34, 36, 42, 48, 51). They are more closely related to the chromosomal β-lactamase of Klebsiella oxytoca than to the TEM or the SHV β-lactamases (5). These cefotaxime-hydrolyzing β-lactamases include the CTX-M and Toho families, of which four subgroups have been recognized on the basis of amino acid sequence homology (6). The first subgroup, the CTX-M-1 subgroup, includes CTX-M-1 (MEN-1) from E. coli in France (5) and Germany (3), CTX-M-3 from C. freundii and E. coli in Poland (15) and from E. coli in Taiwan (51), and CTX-M-10 from E. coli in Spain (34). The second subgroup is represented by CTX-M-2 and includes CTX-M-2 from Salmonella enterica serovar Typhimurium, E. coli, and Proteus mirabilis in Argentina and from K. pneumoniae in Israel and Paraguay (3); Toho-1 ...
Antimicrobial resistance is an increasing problem in Neisseria gonorrhoeae (NG) treatment. Presently, third-generation parenteral cephalosporins, like ceftriaxone and cefotaxime, are the first option. Resistance to oral, but not to parenteral, third-generation cephalosporins has been reported previously. We analysed the microbial susceptibility (as minimum inhibitory concentration - MIC) of NG cultures obtained from high-risk visitors of the largest Dutch outpatient clinic for sexually transmitted infections (STI) in Amsterdam, the Netherlands. Among 1,596 visitors, we identified 102 patients with at least one NG isolate with reduced susceptibility to cefotaxime (0.125 μg/ml < MIC ≤ 0.5 μg/ml). The percentage of NG isolates with reduced susceptibility to cefotaxime rose from 4.8% in 2006 to 12.1% in 2008 (chi2 17.5, p<0.001). With multivariate logistic regression, being a man who has sex with men (MSM) was significantly associated with reduced susceptibility to cefotaxime (p<0.001).
Cefotaxime is a member of the cephalosporin antibiotic class of drugs that has a rather wide spectrum of activity and is useful as a pre-surgery antibiotic.
38 medications are known to interact with cefotaxime. Includes Acetylsalicylic Acid (aspirin), Augmentin (amoxicillin/clavulanate), B Complex 100 (multivitamin).
Mode of action and Anti-microbial spectrum: Cefotaxime is an inhibitor of bacterial cell wall synthesis. High activity against gram-negative bacteria. Very often used for the elimination of Agrobacterium species after inoculation. High resistance against B-lactamase activity. Nontoxic to plant cells.. ...

One strain of Escherichia coli and two strains ofKlebsiella pneumoniae that had high levels of resistance to cefotaxime were isolated from the blood of patients in Seoul National University Childrens Hospital in 1995 and 1996. One strain ofShigella sonnei isolated from a pediatric patient on Cheju Island in 2000 also had a high level of cefotaxime resistance. By disk susceptibility testing, the strains were resistant to amoxicillin, cephalothin, and cefotaxime but were susceptible to ceftazidime, cefoxitin, and amoxicillin-clavulanic acid. Isoelectric focusing showed that the four strains produced a β-lactamase with an isoelectric point (pI) of 8.0. PCR with SHV-specific primers (3) was negative for all strains. Cefotaxime resistance was transferred by conjugation (9) from K. pneumoniaestrain 95151 along with a plasmid of 160 kb to E. coli J53 Azir (met proazide resistant) to produce E. coli J53 Azir/pMG267. The β-lactamase gene was cloned from plasmid pMG267 with EcoRI as an 8-kb insert into ...

Renal failure commonly develops in the setting of SBP, and its development is a sensitive predictor of in-hospital mortality. The renal impairment is thought to stem from decreased effective arterial blood volume secondary to the systemic inflammatory response to the infection. In our current practice, there are certain circumstances in which we administer albumin early in the SBP disease course in order to reduce the risk of renal failure and mortality. Ultimately, our current protocol originated from the 1999 study of albumin in SBP by Sort et al.. The trial enrolled adults with SBP and randomized them to treatment with either cefotaxime and albumin infusion 1.5 gm/kg within 6hrs of enrollment, followed by 1 gm/kg on day 3 or cefotaxime alone. The primary outcome was the development of "renal impairment" (a "nonreversible" increase in BUN or Cr by more than 50% to a value greater than 30 mg/dL or 1.5 mg/dL, respectively) during hospitalization. The secondary outcome was in-hospital ...

Multiplicity for the transport of organic anions across the bile canalicular membrane was studied in vivo and in vitro using dibromosulfophthalein (DBSP), [14C]cefodizime, [3H]leukotriene C4 (LTC4) and indocyanine green (ICG) as model compounds in rats. A high concentration of DBSP in plasma reduced the biliary excretion of cefodizime and leukotriene radioactivity to about 15 and 35% of their control values, respectively, but did not affect the excretion of ICG. A high plasma concentration of ICG reduced the excretion of cefodizime to about 60% of the control value, but exerted minimal effect on the excretion of leukotriene radio-activity and DBSP. In vitro, ATP-dependent uptake of LTC4 into the canalicular membrane vesicles was reduced by DBSP, cefodizime and ICG in a dose-dependent manner, with approximate IC50 values of 0.1 microM, 10 microM, and 1 microM, respectively. The hepatic unbound concentration of DBSP sufficient to reduce the excretion of cefodizime, leukotriene radioactivity and ...
Participants may benefit from early antibiotic treatment. The antibiotic cefotaxime has already been confirmed to be safe and effective for the treatment of severe sepsis and is not under scrutiny in this study. Cefotaxime is widely used, generally well tolerated, and is the locally approved broad-spectrum antibiotic for the treatment of sepsis in Cardiff and Vale University Health Board. It is given to patients on admission to hospital as part of standard care. The more common side effects include diarrhoea, nausea, or abdominal discomfort, and are usually mild and temporary. Rarely observed side effects include allergic reactions, with the potential for anaphylaxis (a severe allergic reaction). Treatment of anaphylactic reactions is routine for paramedics, who have access to adrenaline and salbutamol for treating symptoms. Therefore the potential benefits of early use of cefotaxime by paramedics far outweigh the risks of an anaphylactic reaction. Participants who agree to follow up at 90 days ...

ESBL/AmpC producing Enterobacteriaceae have been reported worldwide amongst isolates obtained from humans, food-producing animals, companion animals and environmental sources. However, data on prevalence of fecal carriage of ESBL/AmpC producing Enterobacteriaceae in healthy companion animals is limited. This pilot study describes the prevalence of ESBL/AmpC encoding genes in healthy cats and dogs, and cats and dogs with diarrhea. Twenty fecal samples of each group were cultured on MacConkey agar supplemented with 1 mg/L cefotaxime and in LB-enrichment broth supplemented with 1 mg/L cefotaxime, which was subsequently inoculated on MacConkey agar supplemented with 1 mg/L cefotaxime. ESBL/AmpC genes were identified using the Check-Points CT103 micro array kit and subsequently by sequencing analysis. Chromosomal ampC promoter mutations were detected by PCR and sequencing analysis. From the healthy and diarrheic dogs, respectively 45% and 55% were positive for E. coli with reduced susceptibility for

If this kit seems expensive, just think how much money and time it costs to take off work, see a doctor and fill a prescription that isnt good for you anyway. Also, definitely continue taking by-mouth probiotics when youre finished, for long-term relief of symptoms. ...
A cross-sectional study was conducted from 2014 to 2017 in 13 organised pig farms located in eight states of India (Northern, North-Eastern and Southern regions) to identify the risk factors, pathotype and antimicrobial resistance of Escherichia coli associated with pre- and post-weaning piglet diarrhoea. The data collected through questionnaire survey were used to identify the risk factors by univariable analysis, in which weaning status, season, altitude, ventilation in the shed, use of heater/cooler for temperature control in the sheds, feed type, water source, and use of disinfectant, were the potential risk factors. In logistic regression model, weaning and source of water were the significant risk factors. The piglet diarrhoea prevalence was almost similar across the regions. Of the 909 faecal samples collected (North - 310, North-East - 194 and South - 405) for isolation of E. coli, pathotyping and antibiotic screening, 531 E. coli were isolated in MacConkey agar added with cefotaxime, ...

The principal objective of the study is to examine if mortality of childhood bacterial meningitis can be reduced by slow continuous infusion of cefotaxime combined with high-dose paracetamol orally for the first 4 days (instead of the traditional qid administration of cefotaxime without concomitant paracetamol). Children qualifying for entry (see criteria below), whose guardian has given informed consent,will be randomized into 2 treatment arms (see details below)and receive the treatments in a double blind fashion (see details below). Primary and secondary outcomes (detailed below) will be evaluated according to predefined criteria and time points (see below).. Results will be analyzed for all patients in ITT datasets and in prespecified subgroups (etiology, nutritional status, etc.) in both crude and adjusted analysis. The efficacy results will be expressed as OR with 95% confidence intervals. ...

The 7-bromoacetyl-7-desacetyl (BrAcFsk) and 7-chloroacetyl-7-desacetyl (CIAcFsk) analogs of forskolin were synthesized as alkylating agents to study the high affinity binding sites for forskolin. BrAcFsk and CIAcFsk activated adenylate cyclase in human platelet membranes with EC50 values of about 20 and 12 microM, respectively. Both analogs increased cyclic AMP in human platelets; however, they were less potent that forskolin. Forskolin inhibited [3H]forskolin binding to human platelet membranes with an IC50 of 20 nM, whereas BrAcFsk and CIAcFsk inhibited [3H] forskolin binding with IC50 values of 0.1 microM. Pretreatment of intact platelets with 10 microM BrAcFsk caused a 90% irreversible loss in [3H]forskolin binding sites, whereas pretreatment with 10 microM CIAcFsk led to a loss of 55% of the binding sites. The loss of binding sites occurred within 5 min for BrAcFsk and within 30 min for CIAcFsk. The time required for the loss of binding sites produced by either alkylating agent was ...

5185 The potent induction of apoptosis in various types of tumor cells, contrasted to largely reversible non-apoptotic effects in normal cells is one of the hallmarks of a novel dual-action DNA- and protein-alkylating drug, irofulven (hydroxymethylacylfulvene). Previous studies suggested the contribution of both nuclear and cytoplasmic signaling to apoptosis by irofulven. To better understand the nature of the differential responses of tumor and normal cells, we used a cell-free apoptosis mimicking system consisting of isolated nuclei and cytosolic extracts. We examined homologous and heterologous mixes of nuclei and cytosols from cancer cells (CEM and LNCaP-Pro5), which initiate apoptosis in response to irofulven, and from normal cells (NCM 460), which display a non-apoptotic cytostatic response. Cytosols were obtained either from untreated or drug-treated cells. In the latter case, irofulven concentrations were adjusted to provide equal levels of intracellular drug-macromolecule adducts in ...

Fine-needle aspiration cytology (FNAC) performed under ultrasound guidance was diagnostic of infection by Salmonella sp. and negative for acid-fast bacilli. The organism was sensitive to cefotaxime, ceftriaxone and ciprofloxacin. Incision and drainage was done, and a tissue sample sent for microscopy and blood culture confirmed a Salmonella infection sensitive to cefotaxime, ceftriaxone and ciprofloxacin. The culture was also negative for acid-fast bacilli and therefore confirmed the FNAC results. The patient was treated with 1 g ceftriaxone intravenously twice daily for 2 weeks. Repeat FNAC a month later was negative.. Discussion. Thyroid abscesses account for 0.1% of all diseases of the thyroid gland.[1] Factors predisposing to thyroid abscesses include immunosuppressive states such as HIV infection or diabetes.[1] Our patient was HIV-positive and in an advanced stage of the disease, with a CD4+ count of 67 cells/,il despite being on HAART.. S. aureus is the main organism causing thyroid ...
7 days of age. After confirmation of GBS, penicillin alone should be used for the rest of the treatment, including the 14-day post-sterilization therapy. For suspected Gram-negative enteric(including E. coli) meningitis a combination of cefotaxime and aminoglycoside, usually gentamicin, is recommended. This treatment should last for 14 days after sterilization and then only cefotaxime for another 7 days creating a minimum of 21 days of therapy post-sterilization. L. meningitis should be treated with a combination of ampicillin and gentamicin because it is synergistic in vitro and provides more rapid bacterial clearance in animal models of infection. After sterilization of CSF, ampicillin should be stopped and gentamicin continued for another 14 days. S. pneumonia can be treated with a combination of penicillin and ampicillin. In cases of herpes simplex virus-derived meningitis, antiviral therapy (acyclovir or vidarabine) must be started immediately for a favorable outcome. Acyclovir is a better ...
Odicef-T from Galpha, Ceftriaxone - Axone-SB to Cadizone | Ceftriaxone is a third-generation cephalosporin antibiotic. Use of Odicef-T from Galpha, Pregnancy, lactation in childrens and special precautions for Odicef-T from Galpha, prices of Odicef-T from Galpha . Like other third-generation cephalosporins, it has broad spectrum activity against Gram positive and Gram negative bacteria. In most cases, it is considered to be equivalent to cefotaxime in terms of safety and efficacy.Ceftriaxone is often used (in combination, but not direct, with macrolide and/or aminoglycoside antibiotics) for the treatment of community-acquired or mild to moderate health care-associated pneumonia. It is also a choice drug for treatment of bacterial meningitis. In pediatrics, it is commonly used in febrile infants between 4 and 8 weeks of age who are admitted to the hospital to exclude sepsis. The dosage for acute ear infection in the very young is 50 mg/Kg IM, one dose only. It has also been used in the treatment of Lyme
The implementation of pneumococal conjugate vaccines (PCVs) 7 then 13 valent (Prevenar13®) in 2010-2011 has significantly changed the profile of pneumococcal meningitis. Since 3 years, the National Pediatric Meningitis Network of the Pediatric Infectious Disease Group (GPIP) and the National Reference Centre of Pneumococci have reported no cases of meningitis due to pneumococcus resistant to third-generation cephalosporins (3GC): cefotaxime or ceftriaxone. In the light of these new data, vancomycin should no longer be prescribed at the initial phase of pneumococcal meningitis treatment (confirmed or only suspected) and this antibiotic should only be added when 3GC minimum inhibitory concentration of the strain isolated is greater than 0 ...
piperacillin-tazobactam. In addition, this O104 strain posses an ability to produce special enzymes that give it what might be called "bacteria superpowers" known technically as ESBLs:. "Extended-Spectrum Beta-Lactamases (ESBLs) are enzymes that can be produced by bacteria making them resistant to cephalosporins e.g. cefuroxime, cefotaxime and ceftazidime - which are the most widely used antibiotics in many hospitals," explains the Health Protection Agency in the UK (http://www.hpa.org.uk/Topics/Infect…).. On top of that, this O104 strain possesses two genes - TEM-1 and CTX-M-15 - that "have been making doctors shudder since the 1990s," reports The Guardian (http://www.guardian.co.uk/commentis…). And why do they make doctors shudder? Because theyre so deadly that many people infected with such bacteria experience critical organ failure and simply die.. Bioengineering a deadly superbug. So how, exactly, does a bacterial strain come into existence thats resistant to over a dozen antibiotics ...

It is interesting to note that one recent study of antimicrobial prophylaxis in the intensive care setting that did not use a systemic antimicrobial at the beginning of oral decontamination did not show statistically significant reductions in nosocomial infection [5]. We attempted to limit the provision of cefotaxime prophylaxis to approximately 72 hours, the time required in our experience to decontaminate the digestive tract of potential pathogenic microorganisms as assessed by surveillance cultures. In our study, 2 of 12 (17%) and 6 of 36 (17%) infections occurred in the first 72 hours in cefotaxime-treated and non-cefotaxime-treated patients, respectively ...

Just a few months ago an excellent of mine was revealing me about a novel wine preservation gadget. That he suggested that I make an effort out the new Epicurean Preservation System EPS. "My Vacu Vin works equally fine," I insisted. Reluctantly, I moved forward for this challenge, wondering worries that time why My partner was doing this. Even as a sommelier and the wine writer, I am over and over again asked to review homemade wine and wine related goods. Research is a critical component to further wine beverages education and any outstanding written review, so My partner accepted my friends problem. I contacted the Epicurean International Company presorvav and thus before I knew keep in mind this I was speaking when it comes to Anthony Lemme. I was the routine recipient of an effective seminar regarding the amazing advantages of their Epicurean Resource efficiency System versus the provides of the Vacu Vin. According to Mr. Lemme and their companys research, "Our patent pending dual-action ...

Campylobacter jejuni and Campylobacter coli strains, isolated from slaughtered chickens and human feces, were examined for their susceptibility to six antibiotics (ampicillin, cefotaxime, erythromycin, levofloxacin, nalidixic acid and trimethoprim) by broth microdilution, for minimum inhibitory concentration determination, and disc diffusion assays. For the 32 C. jejuni isolates, the highest levels of resistance were to trimethoprim (65.6% of the isolates by broth microdilution and 62.5% by disc diffusion) and cefotaxime (62.5% by both methods). Comparable levels of resistance to these antibiotics were found in the 24 C. coli isolates. Statistically significant differences were found between all C. coli isolates for cefotaxime (P = 0.0043) using disc diffusion. A high proportion of C. jejuni isolates show resistance to nalidixic acid using both the broth microdilution (59.4%) and disc diffusion (56.2%) methods. C. coli strains were resistant to this antibiotic showing proportions of 75% when ...
Objectives: We studied the species distribution and antimicrobial susceptibility of viridans streptococci (VS) isolates causing nosocomial bloodstream infections (BSIs) in Finnish hospitals. Patients and methods: Patients with nosocomial BSIs due to VS were identified through a hospital-wide prospective laboratory-based surveillance in two university and two regional hospitals during September 1998-August 2001. Isolates of VS were sent to the reference laboratory for species confirmation and antimicrobial susceptibility testing.. Results: A total of 2038 nosocomial BSIs were identified; 108 (5%) of the BSIs were caused by VS. Of the VS BSIs, 66% were in patients with a haematological malignancy, 14% in patients with a solid tumour and 18% in patients who had undergone surgery preceding the infection. The most common species group identified was Streptococcusmitis (82%). High-level penicillin resistance (≥4mg/L) and cefotaxime resistance (≥4mg/L) were present in 5% and 4% of isolates, ...
TY - JOUR. T1 - Selective inactivation of aminoglycosides by newer beta-lactam antibiotics. AU - Jorgensen, J. H.. AU - Crawford, S. A.. PY - 1982. Y1 - 1982. N2 - Combinations of aminoglycoside and beta-lactam antibiotics may act synergistically against certain microorganisms. However, aminoglycosides have been shown to interact chemically with certain beta-lactam antibiotics resulting in diminished activity of the aminoglycoside. Two beta-lactam antiotics, moxalactam and cefotaxime, as well as several other beta-lactams in current use, were studied for possible inactivation of gentamicin, tobramycin and amikacin. Aqueous mixtures of each of the three aminoglycosides plus a beta-lactam antibiotic (moxalactam, cefotaxime, cephalothin, carbenicillin, ticarcillin or penicillin) were prepared in ratios of 10:1 and 50:1 (beta-lactam: aminoglycoside). Gentamicin and tobramycin were markedly inactivated by carbenicillin and ticarcillin, and to a lesser degree by penicillin (only at the 50:1 ratio), ...

  • In addition, the hypothesis is that, contrary to current data, cefotaxime is found at sufficiently high concentrations in the feces to have an impact on the microbiota equivalent to that of ceftriaxone, despite less significant biliary elimination. (centerwatch.com)
  • A mixed culture of an hypermutable hexA Streptococcus pneumoniae mutant strain and its hexA + isogenic ancestor was challenged with low cefotaxime concentrations. (asm.org)
  • Despite identical original cefotaxime MICs, the hexA mutant population was significantly selected at very low concentrations, and all of the tested selected variants harbored the Thr550→Ala mutation in pbp2x . (asm.org)
  • A competition model-system was established here to test whether subinhibitory cefotaxime concentrations were able to select a hypervariable hexA mutant S. pneumoniae population over its isogenic hexA + ancestor and also to determine the reasons and possible consequences of this selective event. (asm.org)
  • Cefotaxime also is distributed into milk in low concentrations. (elephantcare.org)
  • Cefotaxime serum concentrations were measured in 78 pediatric SCD patients receiving cefotaxime intravenously at a daily dose of 200 mg/kg of body weight in three or four divided doses over 30 min. (cdc.gov)
  • Cefotaxime concentrations ranged from 0.05 to 103.7 mg/liter. (cdc.gov)
  • A total of 38 drugs (338 brand and generic names) are known to interact with cefotaxime . (drugs.com)
  • Insights into the binding of the drugs diclofenac sodium and cefotaxime sodium to serum albumin: calorimetry and spectroscopy. (abcam.com)
  • All commonly used IV fluids and the following drugs are reportedly compatible with cefotaxime: metronidazole and verapamil. (elephantcare.org)
  • These drugs may interact and can change the course of medicine therefore do not use it with cefotaxime. (gdycc.org)
  • Pharmacokinetics (specific) - Cefotaxime is not appreciably absorbed after oral administration and must be given parenterally to attain therapeutic serum levels. (elephantcare.org)
  • Cefotaxime pharmacokinetics were best described by a one-compartment model: the median estimated weight-normalized volume of distribution and clearance were 0.42 liter/kg (range, 0.2 to 1.1 liter/kg) and 0.38 liter/h/kg (range, 0.1 to 1.2 liter/h/kg). (cdc.gov)
  • This is not a complete list of cefotaxime drug interactions. (rxwiki.com)
  • Approximately 20-36% of an intravenously administered dose of 14 C-cefotaxime is excreted by the kidney as unchanged cefotaxime and 15-25% as the desacetyl derivative, the major metabolite. (nih.gov)
  • Notable organisms against which cefotaxime is not active include Pseudomonas and Enterococcus. (wikipedia.org)
  • de Vries H JC , van der Helm J J , Schim van der Loeff M F , van Dam A P . Multidrug-resistant Neisseria gonorrhoeae with reduced cefotaxime susceptibility is increasingly common in men who have sex with men, Amsterdam, the Netherlands. (eurosurveillance.org)
  • Despite their similar spectrum of action, it should be noted that they have substantially different pharmacokinetic properties, especially with regard to their half-life and their elimination routes (mainly urinary for cefotaxime, mixed: biliary and urinary for ceftriaxone). (centerwatch.com)
  • While regional susceptibilities must always be considered, cefotaxime typically is effective against these organisms (in addition to many others): Staphylococcus aureus (not including MRSA) and S. epidermidis Streptococcus pneumoniae and S. pyogenes Escherichia coli Haemophilus influenzae Neisseria gonorrhoeae and N. meningitidis Klebsiella spp. (wikipedia.org)
  • Cefotaxime is used for septicemia and treatment of susceptible organisms. (medscape.com)
