Efflux-mediated aminoglycoside and macrolide resistance in Burkholderia pseudomallei. (1/1407)

Burkholderia pseudomallei, the causative agent of melioidosis, is intrinsically resistant to a wide range of antimicrobial agents including beta-lactams, aminoglycosides, macrolides, and polymyxins. We used Tn5-OT182 to mutagenize B. pseudomallei to identify the genes involved in aminoglycoside resistance. We report here on the identification of AmrAB-OprA, a multidrug efflux system in B. pseudomallei which is specific for both aminoglycoside and macrolide antibiotics. We isolated two transposon mutants, RM101 and RM102, which had 8- to 128-fold increases in their susceptibilities to the aminoglycosides streptomycin, gentamicin, neomycin, tobramycin, kanamycin, and spectinomycin. In addition, both mutants, in contrast to the parent, were susceptible to the macrolides erythromycin and clarithromycin but not to the lincosamide clindamycin. Sequencing of the DNA flanking the transposon insertions revealed a putative operon consisting of a resistance, nodulation, division-type transporter, a membrane fusion protein, an outer membrane protein, and a divergently transcribed regulatorprotein. Consistent with the presence of an efflux system, both mutants accumulated [3H] dihydro streptomycin, whereas the parent strain did not. We constructed an amr deletion strain, B. pseudomallei DD503, which was hypersusceptible to aminoglycosides and macrolides and which was used successfully in allelic exchange experiments. These results suggest that an efflux system is a major contributor to the inherent high-level aminoglycoside and macrolide resistance found in B. pseudomallei.  (+info)

The effect of streptomycin, oxytetracycline, tilmicosin and phenylbutazone on spermatogenesis in bulls. (2/1407)

To determine whether declining semen quality associated with health problems may be due to certain antibiotic or anti-inflammatory treatments, semen was collected 3 times per week for up to 42 d from 6 normal bulls after treatment with oxytetracycline, tilmicosin, dihydrostreptomycin, or phenylbutazone. No adverse effects on semen quality were observed.  (+info)

Enterococcal endocarditis: duration and mode of treatment. (3/1407)

This report summarizes data on sixteen patients with enterococcal endocarditis treated with penicillin and streptomycin. The experience reported suggests that a four week period is adequate for routine therapy in these patients, as in other forms of streptococcal endocarditis. It provides an additional group of patients successfully treated with penicillin and streptomycin. Two relapses were encountered. One of these received inadequate daily doses of penicillin. The other patient was clearly a failure of penicillin and streptomycin, but the failure in this instance could not be attributed to foreshortened treatment (6 weeks) or to high level streptomycin resistance of the infecting strain of Enterococcus.  (+info)

A five-year assessment of controlled trials of in-patient and out-patient treatment and of plaster-of-Paris jackets for tuberculosis of the spine in children on standard chemotherapy. Studies in Masan and Pusan, Korea. Fifth report of the Medical Research Council Working Party on tuberculosis of the spine. (4/1407)

In two centres in Korea 350 patients with a diagnosis of tuberculosis of the thoracic and/or lumbar spine were allocated at random: in Masan to in-patient rest in bed (IP) for six months followed by out-patient treatment or to ambulatory out-patient treatment (OP) from the start; in Pusan to out-patient treatment with a plaster-of-Paris jacket (J) for nine months or to ambulatory treatment without any support (No J). All patients recieved chemotherapy with PAS with isoniazid for eighteen months, either supplemented with streptomycin for the first three months (SPH) or without this supplement (PH), by random allocation. The main analysis of this report concerns 299 patients (eighty-three IP, eighty-three OP, sixty-three J, seventy No J; 143 SPH, 156 PH). Pre-treatment factors were similar in both centres except that the patients in Pusan had, on average, less extensive lesions although in a greater proportion the disease was radiographically active. One patient (J/SPH) died with active spinal disease and three (all No J/SPH) with paraplegia. A fifth patient (IP/PH) who died from cardio respiratory failure also had pulmonary tuberculosis. Twenty-three patients required operation and/or additional chemotherapy for the spinal lesion. A sinus or clinically evident abscess was either present initially or developed during treatment in 41 per cent of patients. Residual lesions persisted in ten patients (four IP, two OP, one J, three No J; six SPH, four PH) at five years. Thirty-two patients had paraparesis on admission or developing later. Complete resolution occurred in twenty on the allocated regimen and in eight after operation or additional chemotherapy or both. Of the remaining four atients, all of whom had operation and additional chemotherapy, three died and one still had paraparesis at five years. Of 295 patients assessed at five years 89 per cent had a favourable status. The proportions of the patients responding favourably were similar in the IP (91 per cent) and OP (89 per cent) series, in the J (90 per cent) and No J (84 per cent) series and in the SPH (86 per cent) and PH (92 per cent) series.  (+info)

In vitro activities of antibiotics alone and in combination against Brucella melitensis at neutral and acidic pHs. (5/1407)

Brucellae survive acidic pHs in phagolysosomes. Azithromycin, streptomycin, and quinolones were active against Brucella melitensis at pH 7.0 but not at pH 5.0; rifampin and doxycycline retained activity at pH 5.0. Regardless of pH, azithromycin-rifampin and ofloxacin-rifampin showed less synergy than established streptomycin-doxycycline and rifampin-doxycycline combinations.  (+info)

Estimation of growth rates of Escherichia coli BJ4 in streptomycin-treated and previously germfree mice by in situ rRNA hybridization. (6/1407)

The growth physiology of Escherichia coli during colonization of the intestinal tract was studied with four animal models: the streptomycin-treated mouse carrying a reduced microflora, the monoassociated mouse with no other microflora than the introduced strain, the conventionalized streptomycin-treated mouse, and the conventionalized monoassociated mouse harboring a full microflora. A 23S rRNA fluorescent oligonucleotide probe was used for hybridization to whole E. coli cells fixed directly after being taken from the animals, and the respective growth rates of E. coli BJ4 in the four animal models were estimated by correlating the cellular concentrations of ribosomes with the growth rate of the strain. The growth rates thus estimated from the ribosomal content of E. coli BJ4 in vivo did not differ in the streptomycin-treated and the monoassociated mice. After conventionalization there was a slight decrease of the bacterial growth rates in both animal models.  (+info)

Alkalinization-induced K+ current of the mouse megakaryocyte. (7/1407)

We have recently found that mouse megakaryocytes responded to extracellular alkalinization to pH > 8.0, generating a K+ current under voltage-clamped conditions with the whole cell recording mode of the patch-clamp technique. The purpose of this study was to physiologically and pharmacologically characterize the alkaline-dependent K+ conductance of the megakaryocyte membrane. The alkalinization-induced K+ current (I(ALK)) did not seem to be Ca2+-dependent since I(ALK) was allowed to be generated under intracellularly Ca2+-buffered conditions with 10 mM EGTA, which completely prevented the generation of caffeine-induced Ca2+-activated currents of mouse megakaryocytes; and no [Ca2+]i elevation was evoked by the alkalinization protocol in contrast to a significant increase in [Ca2+]i in response to caffeine when [Ca2+]i was measured with a fura 2 ratiometry. I(ALK) was strongly suppressed with tetraethylammonium (TEA), 4-aminopyridine (4-AP) and streptomycin (SM), but was completely resistant to quinidine (QND). The values of IC50 for the suppression of I(ALK) with TEA, 4-AP and SM were 5.6, 0.47 and 1.5 mM, respectively. Voltage-gated K+ currents (I(K)) of the same megakaryocyte preparation were weakly suppressed with TEA and 4-AP, while they were significantly suppressed with either SM or QND. These results suggest that mouse megakaryocytes possess K+ conductance that was activated by extracellular alkalinization and that probably differs from conventional K+ conductance in its pharmacological properties.  (+info)

Frequency of F116-mediated transduction of Pseudomonas aeruginosa in a freshwater environment. (8/1407)

Transduction of Pseudomonas aeruginosa streptomycin resistance by a generalized transducing phage, F116, was shown to occur during a 10-day incubation in a flow-through environmental test chamber suspended in a freshwater reservoir. Mean F116 transduction frequencies ranged from 1.4 X 10(-5) to 8.3 X 10(-2) transductants per recipient during the in situ incubation. These transduction frequencies were comparable to transduction frequencies determined in preliminary laboratory transduction experiments. The results demonstrate the potential for naturally occurring transduction in aquatic environments and concurrent environmental and ecological ramifications.  (+info)

The prevalence of selected tetracycline and streptomycin resistance genes and class 1 integrons in Enterobacteriaceae (n = 80) isolated from dairy farm soil and nondairy soils was evaluated. Among 56 bacteria isolated from dairy farm soils, 36 (64.3%) were resistant to tetracycline, and 17 (30.4%) were resistant to streptomycin. Lower frequencies of tetracycline (9 of 24 or 37.5%) and streptomycin (1 of 24 or 4.2%) resistance were observed in bacteria isolated from nondairy soils. Bacteria (n = 56) isolated from dairy farm soil had a higher frequency of tetracycline resistance genes including tetM (28.6%), tetA (21.4%), tetW (8.9%), tetB (5.4%), tetS (5.4%), tetG (3.6%), and tetO (1.8%). Among 24 bacteria isolated from nondairy soils, four isolates carried tetM, tetO, tetS, and tetW in different combinations; whereas tetA, tetB, and tetG were not detected. Similarly, a higher prevalence of streptomycin resistance genes including strA (12.5%), strB (12.5%), ant(3″) (12.5), aph(6)-1c (12.5%), ...

IDENTIFICATION AND USE: streptomycin is an antibiotic produced by the soil actinomycete Streptomyces griseus. It acts by inhibiting the initiation and elongation processes during protein synthesis. Streptomycin is an Aminoglycoside Antibacterial and Antimycobacterial. The chemical classification of streptomycin is Aminoglycosides.. Streptomycin is a broad-spectrum aminoglycoside antibiotic typically used for treatment of active tuberculosis, always in combination with other antituberculosis agents. Streptomycin is usually used in combination with agents that are known to be hepatotoxic and the role of streptomycin in liver injury has been difficult to assess, but most information suggests that streptomycin is not hepatotoxic.. HUMAN EXPOSURE/TOXICITY: intravenous and intramuscular therapy with streptomycin has been linked to mild and asymptomatic elevations in serum alkaline phosphatase, but therapy rarely affects aminotransferase levels or bilirubin and changes typically resolve rapidly once ...
A rising isolation trend of drug-resistant M. bovis from human clinical cases is documented in the literature. Here we assessed Mycobacterium tuberculosis complex isolates from cattle for drug susceptibility by the gold standard agar proportion method and a simplified resazurin microtitre assay (d-REMA). A total of 38 M. tuberculosis complex strains, including M. bovis (n = 36) and M. caprae (n = 2) isolates, from cattle in Tunisia were tested against isoniazid, rifampin, streptomycin, ethambutol, kanamycin and pyrazinamide. M. caprae isolates were found to be susceptible to all test drugs. All M. bovis strains were resistant to pyrazinamide, as expected. In addition, one M. bovis isolate showed high-level resistance to streptomycin (MIC | 500.0 μg/ml). Concordant results with the two methods were found. The most common target genes associated with streptomycin resistance, namely the rrs, rpsL and gidB genes, were DNA sequenced. A non-synonymous mutation at codon 43 (K43R) was found in the rpsL gene.

The Mycobacterium tuberculosis pandemic is a major health problem, further complicated by an increasing incidence of drug-resistant isolates and the existence of highly transmissible strains, such as those in the Beijing family. Streptomycin (STR)-resistant M. tuberculosis clinical isolates have been analyzed to look for mutations in the rpsL, rrs, and gidB genes. In addition, the Rv1258c gene, which encodes Tap, an efflux pump that transports STR, has been sequenced. Mutations affecting codons 43 and 88 of the rpsL gene were found in 44.4% of the strains, and 16.7% of the strains carried mutations in the rrs gene, both of which probably contribute to STR resistance. Many strains presented with mutations in the gidB gene, but the implication of those mutations in STR resistance remains unclear. Interestingly, a cytosine nucleotide insertion between positions 580 and 581 (denominated Tap580) in the Rv1258c gene has been found in all Beijing isolates included in this study, suggesting that it might be a

The substitution of codon 43 in the gene rpsL is the single most common mutation found in streptomycin-resistant Mycobacterium tuberculosis. The characterization of this mutation has been hampered by the need for prior cultivation of the mycobacteria, the need for DNA sequencing, or both. In this report we describe a simple and culture-independent technique to detect this mutation directly from sputum samples, requiring little more than a polymerase chain reaction (PCR) machine and a simple agarose minigel. There is no need for labeled probes or DNA sequencing. In a preliminary test of feasibility, interpretable results were obtained from all of 16 smear-positive and 1 of 4 smear-negative, culture-positive samples. Two of two samples containing M. tuberculosis with rpsL codon 43 mutations were correctly identified.

In the course of a study of streptomycin therapy of infectious diseases conducted at the Vanderbilt University Hospital and other hospitals in Nashville, the striking results which were obtained in the treatment of tularemia focused attention on this disease. These results were so impressive as to justify the conclusion that streptomycin treatment of tularemia is curative, in the strict sense of the word. The high incidence of tularemic pneumonia and the number of occasions in which the source of the infection was obscure and the diagnosis in doubt, suggested that this form of pneumonia is much more prevalent in this ...

There is an arising and concerning issue in the field of bacterial resistance, which is confirmed by the number of deaths associated with drug-resistant bacterial infections. The aim of this study was to compare the effects of antibiotics on Staphylococcus aureus non-resistant strain and strains resistant to cadmium or lead ions. Metal resistant strains were created by the gradual addition of 2 mM solution of metal ions (cadmium or lead) to the S. aureus culture. An increasing antimicrobial effect of ampicillin, streptomycin, penicillin and tetracycline (0, 10, 25, 50, 75, 150, 225 and 300 µM) on the resistant strains was observed using a method of growth curves. A significant growth inhibition (compared to control) of cadmium resistant cells was observed in the presence of all the four different antibiotics. On the other hand, the addition of streptomycin and ampicillin did not inhibit the growth of lead resistant strain. Other antibiotics were still toxic to the bacterial cells. Significant

Cell culture. Cerebellar granule neurons were isolated from the cerebella of 8-d-old Sprague Dawley rats (supplied by the Biological Services Unit, University College London) as described by Taylor et al. (1997). The neurons were separated from non-neuronal cells by centrifugation at 1200 × g for 20 min through 40.5% Percoll (Sigma, Poole, UK) and were plated in basal medium Eagle (BME; Life Technologies, Paisley, UK) supplemented with 10% fetal calf serum (Globepharm, Esher, UK), 25 mm KCl, 35 mmglucose, and penicillin/streptomycin on polyornithine-coated dishes or glass coverslips. Cells were plated at a density of 5.6 × 105/cm2. Approximately 24 hr after plating, cytosine arabinofuranoside (Sigma) was added to the culture medium to a final concentration of 10 μm to prevent the proliferation of any non-neuronal cells. Using this protocol 95-99% of the cultured cells were neurons (Hatten, 1985; Gao et al., 1991). Apoptosis was induced by reducing the extracellular potassium concentration ...

The dielectrophoretic collection spectra of antibiotic-sensitive and antibiotic-resistant strains of Staphylococcus epidermidis have been determined. These indicate that in the absence of antibiotic treatment there is a strong similarity between the dielectric properties of sensitive and resistant strains, and that there is a significant difference between the sensitive strains before and after treatment with the antibiotic streptomycin after 24 h exposure. This method offers possibilities for the assessment of bacterial resistance to antibiotics.. ...

Although high-level resistance to streptomycin arises from mutations in a ribosomal protein, the source of low-level resistance to this antibiotic remained obscure for several decades. Now that mystery is solved, although it raises several others, according to Kenji Nishimura, Susumu Okamoto, and others who work with Kozo Ochi at the National Food Research Institute, Tsukuba, Japan. They report that low-level streptomycin resistance arises because of a mutation to a gene encoding a specific methyl transferase that, in turn, leaves a particular nucleotide unmethylated at the site along the ribosome called the 530 loop. In this unmethylated state, the ribosome remains capable of making proteins even in the presence of streptomycin, which ordinarily blocks protein synthesis.

Easy to read patient leaflet for Streptomycin. Includes indications, proper use, special instructions, precautions, and possible side effects.
The purpose of the experiment was to determine whether the bacteria, E.coli, that acquired resistance to the antibiotics, Streptomycin, over generations would maintain the bacterias antibiotic resistance or if the bacteria would revert back to its original state of susceptibility. Three sets of bacteria were tested over nine days. For the first four days, or generations, the bacterium was treated with the antibiotic. The next four days, the bacterium was not treated with antibiotics. On the ninth day, the bacterium was again treated with the antibiotic. The researchers conducted two 2-sample t-tests to compare the zones of inhibition, or areas of non-growth, of the first generation to the fourth generation, and the first generation to the ninth generation. The zone of inhibition decreased from the first generation to the ninth generation, signaling that Streptomycin resistance was successfully bred into the bacterium. The zone of inhibition from the first generation was very close in size to ...

The Janus cassette permits marker-free allelic replacement or knockout in streptomycin-resistant Streptococcus pneumoniae (pneumococcus) through sequential positive and negative selection. Spontaneous revertants of Janus can lead to high level of false-positives during negative selection, which necessitate a time-consuming post-selection screening process. We hypothesized that an additional counter-selectable marker in Janus would decrease the revertant frequency and reduce false-positives, since simultaneous reversion of both counter-selectable makers is much less likely. Here we report a modified cassette, Sweet Janus (SJ), in which the sacB gene from Bacillus subtilis conferring sucrose sensitivity is added to Janus. By using streptomycin and sucrose simultaneously as selective agents, the frequency of SJ double revertants was about 105-fold lower than the frequency of Janus revertants. Accordingly, the frequency of false-positives in the SJ-mediated negative selection was about 100-fold ...

The production of streptomycin using Streptomyces griseus using two types of chitin as a substrate was studied using a variety of fermentation techniques. Commercial chitin was obtained (Sigma) and comprised chemically purified crab shell. Pre-fermented chitin was the solid product from the lactic acid fermentation of shrimp waste using Lactobacillus paracasei A3. Bioassay, HPLC and FTIR methods were developed during this project for the quantification of streptomycin both in liquid phase and adsorbed on solid chitin surfaces. Shake flask experiments were carried out to determine basic production kinetics, as well as to establish if commercial and pre-fermented chitins produced different quantities of streptomycin. Shake flasks were also used to evaluate any effect of chitin concentration on streptomycin production. A range of submerged fermentations were undertaken in a standard 2 L bioreactor fitted with Rushton Turbines, at chitin concentrations from 0.4 %w/v to 10 %w/v, to study the effect ...

Streptomycin is an aminocyclitol-aminoglycoside antibiotic produced by Streptomyces griseus. Streptomycin consists of aminocyclitol (streptidine), 6-deoxyhexose (streptose), and N-methyl-L-glucosamine moieties, which are formed by independent biosynthetic pathways. All of the moieties are derived from D-glucose. The streptidine moiety is synthesized via myo-inositol, which is then oxidized at C-1 and transaminated to give scyllo-inosamine. After phosphorylation, the compound is transamidinated by arginine. The same procedure is repeated at the C-3 position. The streptose moiety is made from D-glucose via a dTDP-glucose pathway. The exact biosynthetic route for the N-methyl-L-glucosamine moiety is unknown, though the biosynthetic gene cluster have been proposed ...
Chemical control of bacterial canker of kiwifruit caused by Pseudomonas syringae pv. actinidiae was attempted by spraying of streptomycin sulfate ·oxytetracycline WP streptomycin WP streptomycin ·copper hydroxide WP kasugamycin SL kasugamycin·copper oxychloride WP and copper hydroxide WP. The control efficacies of the bactericides were variable depending upon the spraying schedule,. Application of streptomycin WP and streptomycin sulfate·oxytetracycline WP from middle April to early May was found to be the most effective in controlling the bacterial canker. For copper hydroxide WP the spraying from middle January to early February showed the highest control efficacy. Kasugamycin SL was the most effective in controlling the disease by spraying from middle April to early May but it was still relatibvely effective during other spray periods. Foliar application of copper hydroxide WP and copper-antibiotic formulaions after middle April caused severe phytotoxicity. Kasgamycil SL streptomycin WP ...
Summary 1. The use of media treated with streptomycin or penicillin increased the number of positive cultures of E. histolytica obtained from stool specimens containing cysts. 2. It seemed that the favorable influence on amebic cultivation was due to the inhibition of the mixed bacterial flora induced by these drugs. 3. Streptomycin suppressed the aerobic bacteria in some of the cultures and it was observed that slants of Endamoeba medium overlaid with serum-saline supported the growth of certain anaerobic bacteria under aerobic conditions. 4. In some instances, failure of amebic cultivation may have been related to antibiotic influences created by the microbiologic population.

Three extraction methods were employed: (1) boiling in water for 1 hour, (2) maceration for 24 hours in water or (3) 80% ethanol at room temperature.. Among all the extracts studied, the ethanolic extract of Hou Po, or Magnolia bark, demonstrated the most robust antimicrobial activities against the four tested viruses, equivalent to at least 50% of the activities of the standard antibiotics.. Hou Po was most active against M. smegmatis, 20% more than the standard antibiotic streptomycin. The boiled extract of Hou Po had comparable antimicrobial activities to those of streptomycin.. These data suggest that Hou Po may be a potential agent to treat infections caused by M. smegmatis (such as tuberculosis and leprosy) and Mycobacterium tuberculosis. It was reported that magnolol and honokiol exhibited antibacterial activities against methicillin-resistant S. aureus and vancomycin-resistant enterococci - the super bug. These results suggest a new discovery of synergism between magnolol and ...

High-level aminoglycoside resistance (HLAR) in enterococci is most commonly detected by assessing growth at high concentations of gentamicin (500 µg/ml) and sometimes streptomycin (1,000 µg/ml in broth and 2,000 µg/ml in agar) ( 1 ). Strains that show HLAR to gentamicin will not be synergistically killed with combinations of cell wall-active drugs (generally ampicillin, penicillin, or vancomycin) plus gentamicin. HLAR to gentamicin also means HLAR to tobramycin, netilmicin, amikacin, and kanamycin. HLAR to streptomycin equals resistance to combinations of cell wall-active drugs and streptomycin. See additional information in Appendix 5.5-1 . The agar screen test is described in detail here, and reference is made to the disk diffusion and the broth microdilution MIC test procedures for detecting HLAR.
When researchers found out in late 1920s that soybean could produce lubricants and plastic as well as oils and high protein meal, US farmers started to increase soybeans planting heavily. Henry Ford played a major role as a research financier as well as buyer and seller of the soybeans. Because of the giant oil reserve was discovered in Saudi Arabia during late 1930s, the need for low-cost alternative to petroleum vanished. Soybean stocks were started to use as a feed for heavily increasing chicken production. However, the chicken were not growing fast enough and nutritious boost was needed. Researchers discovered that a byproduct of making antibiotic streptomycin could be fed to fatten the chicken ...

Acid-sensing ionic channels (ASICs) have been shown to have a significant role in a growing number of physiological and pathological processes, such as nociception, synaptic transmission and plasticity, mechano-sensation and acidosis-induced neuronal injury. The discovery of pharmacological agents targeting ASICs has significant therapeutic potential and use as a research tool. In our work, we studied the action of transient perfusion (5 to 15 s) of aminoglycosides (AGs) (streptomycin and neomycin) on the proton-gated ionic currents in dorsal root ganglion neurons (DRG) of the rat and in HEK-293 cells. In DRG neurons, streptomycin and neomycin (30 μM) produced a significant, concentration-dependent and reversible reduction in the amplitude of the proton-gated current, and a slowing of the desensitization rate of the ASIC current. Gentamycin (30 μM) also showed a significant reversible action on the ASIC currents. The curves of the pH-effect for streptomycin and neomycin indicated that their ...

streptobicillin depot: combination of benzathine penicillin, streptomycin sulfate & vitamin A oleosum in suitable base for treating mastitis in cows
SUMMARY: An R factor complex, JR66, consisted of JR66a, a self-transmissible plasmid conferring resistance to streptomycin and kanamycin and capable of mobilizing JR66b: JR66b was a non-self-transmissible plasmid conferring resistance to gentamicin, streptomycin, tetracycline, chloramphenicol, kanamycin and sulphonamides. It was a member of compatibility group FII. JR66a, which determined I pili, was incompatible with members of two distinct groups, I and B. Plasmids of both these groups were shown to determine I pili.

Between 1935 and 1944 the field of microbiology, and by implication medicine as a whole, underwent dramatic advancement. The discovery of the extraordinary antibacterial properties of sulphonamides, penicillin, and streptomycin triggered a frantic hunt for more antimicrobial drugs that was to yield an abundant harvest in a very short space of time.
EDITOR-I should like to comment on the randomised controlled trial of midwife led debriefing to reduce maternal depression by Small et al.1 The first randomised clinical trial was of a drug treatment, streptomycin for pulmonary tuberculosis,2 which has provided the model for clinical trials ever since. In a drug trial we are not usually concerned with who is giving the drug because the effect of the drug itself is being measured. The treatment is impersonal, and we should be justified in assuming that the effect of a drug given by one person will be the same as it would be given by another.. When we carry out trials of more personal treatments, however, as in the trial by Small et al, we should be aware that the treatment given by one operator might not be the same as that given by another. Surgeons are not all equally skilful, for example. So if we were to carry out a trial comparing two surgical techniques the surgeons would be a non-random sample from the wider population of surgeons. This ...
Could the next breakthrough antibiotic come from your backyard? Quite possibly. Medicines like terramycin and streptomycin have been found in soil samples unrelated to medical research, raising the prospect that you and your yard could contribute to the next frontier of drug development. At present, most pharmaceutical companies put far more money into long-term treatments - e.g., cancer drugs - than into antibiotics. Which is why researchers Josiah Zayner and Mark Opal recently started sending out simple test kits for people to look for antibacterial properties in their household plants, gardens and chemicals. This may not uncover the next big medication right away, but, Zayner and Opal argue, it has only positive long-term effects.. Source: NPR ...
Preparation of CD4+ PHA blasts. CD4+ PHA blasts were prepared as described previously (7). In brief, CD4+ T cells, freshly isolated by positive enrichment using MACS CD4 microbeads (Miltenyi Biotec, Bergisch Gladbach, Germany), were seeded into 24-well plates (Nunc, Roskilde, Denmark) at a density of 1 to 2 × 106 cells per well in 1 mL RPMI 1640 supplemented with 25 mmol/L HEPES, 10% heat-inactivated human AB serum from healthy donors, 2 mmol/L l-glutamine, 100 units/mL penicillin, and 100 μg/ mL streptomycin. On day 0, 10 μg/mL phytohemagglutinin (PHA-P, Sigma-Aldrich, St. Louis, MO) were added to the culture. On day 3, half of the medium was replaced with complete medium containing interleukin-2 (IL-2, 20 units/mL) and IL-7 (40 ng/mL), and this was repeated every 3 days. The activated CD4+ T cells were electroporated and used as antigen presenting cells around days 14 to 28 of the culture. Purified recombinant human IL-2 was provided by Takeda Pharmaceutical (Osaka, Japan). No expression of ...
