Acinetobacter bacteremia in Hong Kong: prospective study and review. (1/737)

The epidemiological characteristics of 18 patients with acinetobacter bacteremia were analyzed. Patients (mean age, 55.5 years) developed bacteremia after an average of 14.1 days of hospitalization. Fifteen of 16 patients survived bacteremia caused by Acinetobacter baumannii. Cultures of blood from the remaining two patients yielded Acinetobacter lwoffii. Most patients (78%) resided in the general ward, while four patients (22%) were under intensive care. Genotyping by arbitrarily primed polymerase chain reaction analysis and the temporal sequence of isolation were more useful than phenotyping by antimicrobial susceptibility in the determination of the source of bacteremia, and the intravascular catheter was the leading infection source (39% of cases). The possibility of an association of glucose with the pathogenesis of acinetobacter infection was raised.  (+info)

Risk factors for nosocomial bloodstream infections due to Acinetobacter baumannii: a case-control study of adult burn patients. (2/737)

Risk factors for Acinetobacter baumannii bloodstream infection (BSI) were studied in patients with severe thermal injury in a burn intensive care unit where A. baumannii was endemic. Of 367 patients hospitalized for severe thermal injury during the study period, 29 patients with nosocomial A. baumannii BSI were identified (attack rate, 7.9%). Cases were compared with 58 matched controls without A. baumannii BSI. The overall mortality rate was 31% among cases and 14% among controls; only two deaths (7%) were considered directly related to A. baumannii BSI. Molecular typing of A. baumannii blood isolates by means of randomly amplified polymorphic DNA analysis and pulsed-field gel electrophoresis revealed the presence of three different strain types. Multivariate analysis showed that female gender (P = .027), total body surface area burn of > 50% (P = .016), prior nosocomial colonization with A. baumannii at a distant site (P = .0002), and use of hydrotherapy (P = .037) were independently associated with the acquisition of A. baumannii BSI in burn patients. These data underscore the need for effective infection control measures for this emerging nosocomial problem.  (+info)

Efficacy of sulbactam alone and in combination with ampicillin in nosocomial infections caused by multiresistant Acinetobacter baumannii. (3/737)

From March 1995 to March 1997, sulbactam was prospectively evaluated in patients with non-life-threatening multiresistant Acinetobacter baumannii infections. During this period, 47 patients were treated with sulbactam; of them, five were excluded because they had received < or =48 h of sulbactam therapy. A total of 42 patients, 27 males and 15 females with a mean age of 60+/-15 years, were finally evaluated. Infections were as follows: surgical wound, 19; tracheobronchitis, 12; urinary tract, 7; catheter-related bacteraemia, 2; and pneumonia, 2. Eighteen patients received intravenous sulbactam alone (1 g every 8 h) and 24 patients received intravenous sulbactam/ampicillin (1 g:2 g every 8 h) with no major adverse effects. Of the 42 patients, 39 improved or were cured and showed A. baumannii eradication and one patient had persistence of wound infection after 8 days of sulbactam/ampicillin requiring surgical debridement. Two patients died after 3 days of therapy (one of the deaths was attributable to A. baumannii infection). The in-vitro activity of the sulbactam/ampicillin combination was by virtue of the antimicrobial activity exhibited by sulbactam. Killing curves showed that sulbactam was bacteriostatic; no synergy was observed between ampicillin and sulbactam. Our results indicate that sulbactam may prove effective for non-life-threatening A. baumannii infections. Its role in the treatment of severe infections is unknown. However, the current formulation of sulbactam alone may allow its use at higher doses and provide new potential synergic combinations, particularly for those infections by A. baumannii resistant to imipenem.  (+info)

Identification of Acinetobacter baumannii strains with monoclonal antibodies against the O antigens of their lipopolysaccharides. (4/737)

Despite the emergence of Acinetobacter baumannii strains as nosocomial pathogens, simple methods for their phenotypic identification are still unavailable. Murine monoclonal antibodies specific for the O-polysaccharide moiety of the lipopolysaccharide (LPS) of two A. baumannii strains were obtained after immunization with heat-killed bacteria. The monoclonal antibodies were characterized by enzyme immunoassay and by Western and dot blot analyses and were investigated for their potential use for the identification of A. baumannii strains. The antibodies reacted with 46 of the 80 A. baumannii clinical isolates that were investigated, and reactivity was observed with 11 of 14 strains which were isolated during outbreaks in different northwestern European cities; no reactivity was observed with Acinetobacter strains of other genomic species, including the closely related genomic species 1 (Acinetobacter calcoaceticus), 3, and 13 sensu Tjernberg and Ursing, or with other gram-negative bacterial strains. The results show that O-antigen-specific monoclonal antibodies such as the ones described are convenient reagents which can be used to identify Acinetobacter strains in clinical and research laboratories.  (+info)

Some immunological properties of lipopolysaccharide from Acinetobacter baumannii. (5/737)

Acinetobacter baumannii, mainly biotype 9, is an important nosocomial opportunist pathogen in Chile and other countries. The biological basis of its virulence and prevalence is still unknown. As lipopolysaccharide (LPS) is often associated with virulence, some biological properties of purified LPS from seven nosocomial isolates, comprising four isolates of A. baumannii biotype 9, two isolates of biotype 8 and one isolate of biotype 1, were investigated. LPS was extracted and purified from each isolate by the hot phenol-water method, and its ability to elicit a mitogenic response and to induce the synthesis of a tumour necrosis factor (TNF-alpha) in mouse spleen cells was determined. Activity was evaluated in vivo by determining the splenic index in comparison with LPS from Salmonella Typhimurium. All seven LPS samples were mitogenic on the basis of cellular proliferation experiments and six induced synthesis of TNF-alpha. Similar results were obtained in in-vivo experiments in which LPS induced spleen cell growth, as shown by determination of the splenic index. These results suggest that the LPS of A. baumannii might contribute to the pathogenic properties of this species.  (+info)

Use of a murine O-antigen-specific monoclonal antibody to identify Acinetobacter strains of unnamed genomic species 13 Sensu Tjernberg and Ursing. (6/737)

A monoclonal antibody against the O-antigenic polysaccharide chain of the lipopolysaccharide (LPS) of Acinetobacter strains belonging to the unnamed genomic species 13 Sensu Tjernberg and Ursing (13TU) was obtained after immunization of BALB/c mice with heat-killed bacteria and was characterized by enzyme immunoassay and Western blot analysis, by use of LPS and proteinase K-treated bacterial lysates, analyses in which the antibody was shown to be highly specific for the homologous antigen. In addition, when tested in dot and Western blots, reactivity was observed with 9 of 18 Acinetobacter strains of genomic species 13TU which had been isolated in Germany and Denmark; no reactivity was observed with strains of other genomic species, including the closely related genomic groups 1 (A. calcoaceticus), 2 (A. baumannii), and 3 (unnamed), or with other gram-negative bacteria. The antibody described here represents a convenient reagent for the simple, economical, and accurate differentiation of clinical isolates of genomic species 13TU from other Acinetobacter strains. Although the antibody does not identify all isolates of this genomic group, it is evident that it will be a useful reagent in the development of a serotyping scheme for clinical laboratories.  (+info)

Genotypic and phenotypic similarity of multiresistant Acinetobacter baumannii isolates in the Czech Republic. (7/737)

The diversity of 103 clinical isolates of the Acinetobacter calcoaceticus-Acinetobacter baumannii complex obtained between 1991 and 1997 from 17 Czech hospitals was studied by ribotyping, biotyping, plasmid profiling and antibiotic susceptibility testing. According to the EcoRI ribotypes, all but one of these isolates were identified to the DNA group level: 77 isolates were allocated to DNA group 2 (A. baumannii), 14 to DNA group 3, 10 to DNA group 13 sensu Tjernberg and Ursing and one to DNA group 1 (A. calcoaceticus). In total, 50 different EcoRI ribotypes and 10 biotypes were observed. Plasmids were found in 92% of the isolates and a high variability in plasmid profiles was found in isolates of the same DNA group. The combination of typing profiles allowed two predominant groups (termed A and B) to be distinguished among the A. baumannii isolates (37 and eight isolates, respectively) that shared a specific ribotype and were highly similar in other properties. These two groups comprised both sporadic and outbreak isolates and were found in most localities. Group A and B isolates were markedly more resistant to antibiotics than most of the remaining isolates, thus representing 85% of all multiresistant isolates. The features of groups A and B corresponded to those of two epidemic clones identified recently among hospital strains in north-western Europe.  (+info)

In vivo efficacies of combinations of beta-lactams, beta-lactamase inhibitors, and rifampin against Acinetobacter baumannii in a mouse pneumonia model. (8/737)

The effects of various regimens containing combinations of beta-lactams, beta-lactam inhibitor(s), and rifampin were assessed in a recently described mouse model of Acinetobacter baumannii pneumonia (M. L. Joly-Guillou, M. Wolff, J. J. Pocidalo, F. Walker, and C. Carbon, Antimicrob. Agents Chemother. 41:345-351, 1997). Two aspects of the therapeutic response were studied: the kinetics of the bactericidal effect (treatment was initiated 3 h after intratracheal inoculation, and bacterial counts were determined over a 24-h period) and survival (treatment was initiated 8 h after inoculation, and the cumulative mortality rate was assessed on day 5). Two clinical strains were used: a cephalosporinase-producing strain (SAN-94040) and a multiresistant strain (RCH-69). For SAN-94040 and RCH-69, MICs and MBCs (milligrams per liter) were as follows: ticarcillin, 32, 64, 256, and >256, respectively; ticarcillin-clavulanate, 32, 64, and 512, and >512, respectively; imipenem, 0.5, 0.5, 8, and 32, respectively; sulbactam, 0.5, 0.5, 8, and 8, respectively; and rifampin, 8, 8, 4, and 4, respectively. Against SAN-94040, four regimens, i.e., imipenem, sulbactam, imipenem-rifampin, and ticarcillin-clavulanate (at a 25/1 ratio)-sulbactam produced a true bactericidal effect (>/=3-log10 reduction of CFU/g of lung). The best survival rate (i.e., 93%) was obtained with the combination of ticarcillin-clavulanate-sulbactam, and regimens containing rifampin provided a survival rate of >/=65%. Against RCH-69, only regimens containing rifampin and the combination of imipenem-sulbactam had a true bactericidal effect. The best survival rates (>/=80%) were obtained with regimens containing rifampin and sulbactam. These results suggest that nonclassical combinations of beta-lactams, beta-lactamase inhibitors, and rifampin should be considered for the treatment of nosocomial pneumonia due to A. baumannii.  (+info)

Acinetobacter Infections - Pipeline Review, H1 2017 Summary Latest Pharmaceutical and Healthcare disease pipeline guide Acinetobacter Infections - Pipeline
Bacterial infections due to Acinetobacter species are typically encountered in health care settings and can be particularly difficult to treat due to the propensity of the organism to incorporate multiple antibiotic resistance mechanisms. Hospital outbreaks of multidrug-resistant Acinetobacter infections have been reported. A wide range of infections are possible with this organism, including bloodstream infections, pneumonia (occasionally even community-acquired pneumonia), urinary tract infections, and wound infections (wound infection in soldiers after traumatic injury have been reported ...
Infection with antibiotic-resistant Acinetobacter spp. is an increasing problem in critical care environments worldwide. Acinetobacter spp. are known to produce an insulin-cleaving protease. We hypothesized that infection with Acinetobacter spp. was associated with the acquisition of glucose intolerance in burn patients. Data were collected prospectively on all 473 patients admitted to the Burns Centre between January 2002 and March 2003. A total of 3.4% of patients acquired glucose intolerance during admission. Patients with Acinetobacter spp. infection were 9.8 times more likely to develop glucose intolerance than those without the infection (P | .0001). The association persisted after controlling for TBSA (P | .001). In patients with deep Acinetobacter spp. infection, 47% had glucose intolerance, compared with 12% in those with infection of the burn only (P = .03). In patients with pre-existing diabetes mellitus, 27% developed Acinetobacter spp. infection compared with only 8.5% of patients without

outbreaks of carbapenem-resistant A. baumannii infection occurred in a hospital in New York City. Subsequently, numerous other hospitals in the United States and South America have had outbreaks of carbapenem-resistant A. baumannii. The incidence of infections with A. baumannii among military personnel from the United States and Canada has increased since 2002; 102 patients had bloodstream infections at facilities treating U.S. military personnel injured in Iraq or Afghanistan from January 1, 2002, through August 31, 2004. An epidemiologic investigation revealed that A. baumannii could be grown from environmental sites in field hospitals and that the environmental strains were closely related genotypically to clinical isolates. A. baumannii strains from injured military personnel from the United States and the United Kingdom were also genotypically related; this finding provided further evidence that A. baumannii was being acquired in field hospitals.. ...
Acinetobacter spp. are a diverse group of Gram-negative bacteria frequently implicated in nosocomial infections. Genotypic methods have been instrumental in studying Acinetobacter, but few offer high resolution, rapid turnaround time, technical ease and high inter-laboratory reproducibility, which has hampered understanding of disease incidence, transmission patterns and diversity within this genus. Here, we further evaluated multilocus PCR electrospray ionization/ mass spectrometry (PCR/ESI-MS), a method that is simple and robust, and provides both species characterization and strain-level resolution of Acinetobacter spp. on a single platform. We examined 125 Acinetobacter isolates from 21 hospitals, laboratories and medical centres spanning four counties in Arizona, USA, using PCR/ESI-MS. We compared PCR/ESI-MS with an in-house amplified fragment length polymorphism (AFLP) genotyping scheme. PCR/ESI-MS demonstrated that Acinetobacter spp. from Arizonan hospitals had similar species and strain
Prompt detection of metallo-beta-lactamase (MBL) producing isolates is necessary to prevent their dissemination. Frequency of MBLs producing strains among multidrug resistant (MDR) Acinetobacter species and Pseudomonas aeruginosa was evaluated in critical care Patients using imipenem-EDTA disk method. One hundred MDR Acinetobacter spp. and 42 Pseudomonas aeruginosa were checked for MBL production, from January to June 2001. MBL was produced by 96.6 % of imipenem-resistant Acinetobacter isolates, whereas 100% imipenem-resistant Pseudomonas aeroginosa isolates were MBL producers. Carbapenem resistance in MDR Acinetobacter spp. and Pseudomonas aeruginosa isolates in this study was due to MBLs. This calls for strict infection control measures to prevent further dissemination.
War wound infection and osteomyelitis caused by multidrug-resistant (MDR) Acinetobacter species have been prevalent during the 2003-2005 military operations in Iraq. Twenty-three soldiers wounded in Iraq and subsequently admitted to our facility from March 2003 to May 2004 had wound cultures positive for Acinetobacter calcoaceticus-baumannii complex. Eighteen had osteomyelitis, 2 burn infection, and 3 deep wound infection. Primary therapy for these infections was directed antimicrobial agents for an average of 6 weeks. All soldiers initially improved, regardless of the specific type of therapy. Patients were followed up to 23 months after completing therapy, and none had recurrent infection with Acinetobacter species. Despite the drug resistance that infecting organisms demonstrated in this series, a regimen of carefully selected extended antimicrobial-drug therapy appears effective for osteomyelitis caused by MDR Acinetobacter spp.

Bacterial infection is a major cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Streptococcus pneumoniae (SP) and Haemophilus influenza (HI) are the most frequently encountered.. Objectives: Studying the relation between the bacteriologic etiology of AECOPD and severity of the disease.. Methods: This is a retrospective study of patients with COPD hospitalised for AECOPD and whose bacteriological sputum was used to isolate the causative agent. In this study, we correlated the parameters of severity of the disease with isolated bacteria.. Results: 225 germs were isolated from 180 patients. The infection was polymicrobial in 19 patients. The bacteria isolated were: SP:18 cases, HI:42 cases, Pseudomonas:37 cases and Acinetobacter:14 cases. Patients that experienced pyocyanic and/or Acinetobacter infections are more symptomatic than COPD patients with past history of exacerbations due to HI and/or SP (mMRC=2-4: 86% vs 71%, p=0,049), most often GOLD 3 and 4 (89% vs ...

Objectives. Multidrug-resistant Acinetobacter strain HK302 was isolated from an outbreak of nosocomial infections in Switzerland in 1977. The aim of the present study was to assess whether this archive strain belongs to one of the known international clonal lineages of Acinetobacter baumannii and whether it harbours a genomic structure related to the AbaR1-like resistance islands.. Methods. Multilocus sequence typing (MLST) and HindIII ribotyping were used to determine the taxonomic position of HK302 at the species and subspecies (clonal) levels. The position and structure of the putative resistance island were investigated by AbaR1-based PCR mapping followed by restriction analysis and partial sequencing of amplicons. A. baumannii AYE harbouring AbaR1 was used as a positive control for PCR mapping.. Results. The MLST allelic profile (1-1-1-1-5-1-1) and HindIII ribotype of HK302 were typical of A. baumannii European (EU) clone I. In addition, an AbaR1-related region inserted into the ATPase gene ...
Nosocomial pathogens can be associated with a variety of infections, particularly in intensive care units (ICUs) and in immunocompromised patients. Usually these pathogens are resistant to multiple drugs and pose therapeutic challenges. Among these organisms, Acinetobacter baumannii is one of the most frequent being encountered in the clinical setting. Carbapenems are very useful to treat infections caused by these drug-resistant Gram-negative bacilli, but carbapenem resistance is increasing globally. Combination therapy is frequently given empirically for hospital-acquired infections in critically ill patients and is usually composed of an adequate beta-lactam and an aminoglycoside. The purpose of this study was to evaluate the in vitro activity of plazomicin against carbapenem-resistant Acinetobacter baumannii. Amikacin was used as a comparator. The activity of plazomicin in combination with several different antibiotics was tested by disk diffusion, the checkerboard method, and time-kill ...
Acinetobacter baumannii has been increasingly reported in the outbreak of nosocomial infections in the intensive care units, which not only prolong the length of hospital stay but result in high attributable mortality. With its intrinsic resistance to many antimicrobial agents and rapid acquirement of resistance mechanism, resistance to carbapenems, which is often accompanied with resistance to multiple drugs, has emerged worldwide. The limited treatment choice included tigecycline, colistin, and sulbactam. However, the low serum level and bacteriostatic nature of tigecycline hamper its application in blood stream infection, one of the most common presentations of A. baumannii infections. The nephrotoxicity and neurotoxicity of intravenous colistin have caused great concerns in critically ill patients whereas immediate bronchospasm after inhalation and significant clinical consequences have been reported.

Objective To investigate the in vitro and in vivo antibacterial activities of tigecycline and other 13 common antimicrobial agents, alone or in combination, against multi-drug resistant Acinetobacter baumannii.MethodsAn in vitro susceptibility test of 101 Acinetobacter baumannii was used to detect minimal inhibitory concentrations (MICs). A mouse lung infection model of multi-drug resistant Acinetobacter baumannii,established by the ultrasonic atomization method, was used to define in vivo antimicrobial activities.Results Multi-drug resistant Acinetobacter baumannii showed high sensitivity to tigecycline (98% inhibition), polymyxin B (78.2% inhibition), and minocycline (74.2% inhibition). However, the use of these antimicrobial agents in combination with other antimicrobial agents produced synergistic or additive effects. In vivo data showed that white blood cell (WBC) counts in drug combination groups C (minocycline + amikacin) and D (minocycline + rifampicin) were significantly higher than in groups A
PubMedID: 24985124 | Successful management of an outbreak due to carbapenem-resistant Acinetobacter baumannii in a neonatal intensive care unit. | European journal of pediatrics | 7/2/2014
Carbapenem resistance in A. baumannii is most often associated with class D β-lactamases (OXA-23-like, OXA-40-like and OXA-58-like) and MBLs. OXA-type carbapenemases are predominant in A. baumannii, particularly in worldwide outbreaks of OXA-23 [24]. The molecular analysis of the isolates tested in this study revealed that 14 strains (51.8 %) carried the blaOXA-23-like gene and that two strains carried a blaOXA-24-like gene. All of the strains had a blaOXA-51-like gene, and four strains had a blaOXA-58 gene. In this study, the OXA-58 isolates presented lower MIC values for meropenem than OXA-23-like-positive isolates, which systematically exhibited higher MIC values (Table 1). The isolates with non-acquired OXA genes displayed a marked variation and included some carbapenem-resistant genes. Naturally occurring OXA carbapenemases, such as OXA-51-like enzymes (e.g., OXA 64-66, OXA 68-71, OXA 78-80, OXA-82, OXA-86, OXA-92 and OXA104-112), have been identified in A. baumannii isolates worldwide. In ...

TY - JOUR. T1 - Integron-associated imipenem resistance in Acinetobacter baumannii isolated from a regional hospital in Taiwan. AU - Liu, S. Y.. AU - Lin, J. Y.. AU - Chu, C.. AU - Su, L. H.. AU - Lin, T. Y.. AU - Chiu, C. H.. PY - 2006/1. Y1 - 2006/1. N2 - We investigated the genetic properties of imipenem-resistant Acinetobacter baumannii collected from a regional hospital in Taiwan. Pulsed-field gel electrophoresis demonstrated that the isolates were genetically diverse. Polymerase chain reaction, DNA sequencing, and DNA-DNA hybridisation showed that the blaIMP-1 gene resided as a cassette in a plasmid-borne class 1 integron in two isolates. The majority of the resistant isolates were plasmid-less and carried no blaIMP, blaVIM or bla CFI genes, indicating that other uncharacterised metallo-β- lactamases or mechanisms other than enzyme production are involved in carbapenem resistance in this group of A. baumannii. We conclude that multidrug resistance of A. baumannii was a combined effect of ...
Acinetobacter junii is a species of bacteria. Its type strain is ATCC 17908. It can be pathogenic. This bacterium has been linked to nosocomial infections including catheter-related blood stream infections and cellulitis. Vaneechoutte, M.; De Baere, T.; Nemec, A.; Musilek, M.; Van Der Reijden, T.

Patients with AB bacteremia receiving antimicrobial therapy are eligible for this multicenter study. Antimicrobial agents are decided at the discretion of the attending clinical team. Clinical data to be collected include patient demographics (age, gender, underlying diseases, Pitt Bacteremia Score [20], duration of ICU stay and hospitalization before the day of first positive blood culture, central venous catheterization), antimicrobial agents on the day of bacteremia, regimens and durations of combination therapy after enrollment, and outcomes (sequential quantification change of blood A. baumannii polymerase chain reaction [PCR], survival at day 30 after enrollment, and adverse drug reactions of antimicrobial agents). Blood sample will be collected on the day of enrollment (Day 0), Day 1, 2, 3 and 7 for PCR quantification of A. baumannii and for genospecies identification. Primary end points are the interval from study enrollment to negative blood A. baumannii PCR and blood sterilization. ...
Bacteria of the genus Acinetobacter are ubiquitous in nature. These organisms were invariably susceptible to many antibiotics in the 1970s. Since that time, acinetobacters; have emerged as multiresistant opportunistic nosocomial pathogens. The taxonomy of the genus Acinetobacter underwent extensive revision in the mid-1980s, and at least 32 named and unnamed species have now been described. Of these, Acinetobacter baumannii and the closely related unnamed genomic species 3 and 13 sensu Tjernberg and Ursing (13TU) are the most relevant clinically. Multiresistant strains of these species causing bacteraemia, pneumonia, meningitis, urinary tract infections and surgical wound infections have been isolated from hospitalised patients worldwide. This review provides an overview of the antimicrobial susceptibilities of Acinetobacter spp. in Europe, as well as the main mechanisms of antimicrobial resistance, and summarises the remaining treatment options for multiresistant Acinetobacter infections. © ...
Rates of A. baumannii bacteraemia significantly increased between 2005 and 2009, from 0.1 to 3.2 cases/100,000 inhabitants per year. The observed increase was due to carbapenem-resistant isolates, while the number of carbapenem-susceptible isolates remained substantially stable over the study period. Importantly, the occurrence of carbapenem-resistant isolates showed a steep five-fold increase between 2008 and 2009. These isolates belonged to an epidemic strain detected in several departments of 4 hospital trusts in the Region. Similar trends were observed for urine and respiratory isolates. The total number of isolates in blood, urine and respiratory specimens, including both colonizing and infecting strains, increased from 51 in 2005 to 826 in 2009, with rates rising from 1.5 to 19.0 isolates/100,000 inhabitants per year. ...
As part of the SENTRY Antimicrobial Surveillance Program, a total of 1078 Acinetobacter species and 842 Stenotrophomonas maltophilia isolates were collected between January 1997 and December 1999 from 5 geographic regions (Canada, the United States, Latin America, Europe, and the Asia-Pacific). The frequency of infections (by geographic region and body site), including those due to imipenem-resistant Acinetobacter species and trimethoprim-sulfamethoxazole (TMP-SMZ)-resistant S. maltophilia, was evaluated. The possibility of seasonal variations in bloodstream infections caused by Acinetobacter species was studied, as was the activity of several therapeutic antimicrobials against all strains. Acinetobacter species and S. maltophilia were most frequently associated with pulmonary infections, independent of the region evaluated. In contrast, patterns of antimicrobial resistance markedly varied among distinct geographic regions, especially for nosocomial isolates. Although the carbapenems were the ...

To understand the epidemiology of multidrug-resistant (MDR) Acinetobacter baumannii and define individual risk factors for MDR, we used epidemiologic methods, performed organism typing by pulsed-field gel electrophoresis (PFGE), and conducted a matched case-control retrospective study. We investigated 118 patients, on 27 wards, in whom MDR A. baumannii was isolated from clinical cultures. Each case-patient had a control without MDR A. baumannii and was matched for hospital length of stay, ward, and calendar time. The epidemiologic investigation found small clusters of up to 6 patients each with no common identified source. Ten different PFGE clones were found, of which 2 dominated. The PFGE pattern differed within temporospatial clusters, and antimicrobial drug susceptibility patterns varied within and between clones. Multivariate analysis identified the following significant risk factors: male sex, cardiovascular disease, having undergone mechanical ventilation, and having been treated with
In recent years, the number of nosocomial infections caused byAcinetobacter baumannii has increased significantly (4). Many outbreaks have been reported, especially among patients confined to hospital intensive care units, where the widespread use of antibiotics may select multidrug-resistant strains. The difficulty of treating A. baumannii nosocomial infection is associated with the high resistance to a wide range of antimicrobial agents frequently observed in this species (8). Often, imipenem remains one of the few therapeutic alternatives. Fortunately, imipenem resistance is relatively rare among Acinetobacter clinical isolates. Carbapenem resistance can arise by a decrease in expression of an outer membrane protein (3) or by alteration in penicillin-binding proteins (5). In general, the emergence of carbapenem-hydrolyzing enzymes has been limited compared to the prevalence of other β-lactamases (1). However, in 1985 in Scotland, anA. baumannii strain that produced a plasmid-mediated ...
Multi-drug resistant Acinetobacter baumannii bacteria inside biofilm, computer illustration. A. baumannii is a Gram-negative, oxidase negative, aerobic, coccobacillus. It has always been naturally resistant to multiple antibiotics. It can be especially resistant to penicillin and chloramphenicol. It causes various nosocomial infections, including, skin and wound infections, pneumonia, meningitis, septicaemia, urinary tract infection and endocarditis. It is commonly found in soil, water, sewage, and normal skin and gastrointestinal tract flora. It is the most frequently encountered species in the clinical laboratory. Species found in soil can colonize root nodule systems and oxidize the hydrogen produced by nitrogen fixing bacteria. The illustration shows morphology of Acinetobacter such as short rods and sometimes long filamentous cells. - Stock Image F018/1264
Molecular characterization and antimicrobial susceptibility of Acinetobacter baumannii isolates obtained from two hospital outbreaks in Los Angeles County, California, USA
Acinetobacter baumannii is currently one of the key nosocomial pathogens causing severe infections; of special concern is its resistance to expanded-spectrum cephalosporins (ESCs) and carbapenems, often associated with the few so-called European clones (6, 7, 19). It has two natural -lactamases, an AmpC-like enzyme (Acinetobacter-derived cephalosporinase [ADC]) (10) and a carbapenem-hydrolyzing class D -lactamase (CHDL; the OXA-51 type) (15), which affect susceptibility upon increased expression due to ISAba1 insertion upstream of their genes (9, 18). Moreover, acquired -lactamases, including metallo-lactamases (MBLs) and four CHDL types, the OXA-23, OXA-24/40, OXA-58, and OXA-143 types, are observed (15). Knowledge of A. baumannii in Poland has been limited to single isolates (9, 14, 21); our aim was to analyze a bigger group of A. baumannii strains. (Part of this work was presented at the 22nd European Congress of Clinical Microbiology and Infectious Diseases, London, United Kingdom, 31 March to 3
Acinetobacter (/ˌæsɪˈniːtoʊbæktər/) is a genus of Gram-negative bacteria belonging to the wider class of Gammaproteobacteria. Acinetobacter species are oxidase-negative, exhibit twitching motility, and occur in pairs under magnification. They are important soil organisms, where they contribute to the mineralization of, for example, aromatic compounds. Acinetobacter species are a key source of infection in debilitated patients in the hospital, in particular the species Acinetobacter baumannii. Species of the genus Acinetobacter are strictly aerobic, nonfermentative, Gram-negative bacilli. They show mostly a coccobacillary morphology on nonselective agar. Rods predominate in fluid media, especially during early growth. The morphology of Acinetobacter species can be quite variable in Gram-stained human clinical specimens, and cannot be used to differentiate Acinetobacter from other common causes of infection. Most strains of Acinetobacter, except some of the A. lwoffii strain, grow well on ...
Acinetobacter baumannii causes severe nosocomial infections such as pneumonia, meningitis and sepsis with high mortality rates. This organism represents an increasing danger for immunocompromised adults, especially since there are an increasing number of resistances against antibiotics. Until now, scientific investigation was mainly focused on taxonomy and antibiotic resistance mechanisms. The goal of this project was to analyse the interaction between clinical strains of Acinetobacter baumannii and human cells in order to address the molecular mechanisms causing pathogenicity. Adherence is the first step in colonization of human tissue, and therefore a key event in pathogenesis. To demonstrate the adhesion of bacteria to human cells, a colony counting assay has been established. These experiments used the the type strain of A. baumannii ATCC 19606, as well as clinical isolates. All A. baumannii strains investigated showed adhesion to the lung epithelial cells A549, but the adhesion capacity was ...
