Today methicillin resistant coagulase-negative staphylococci (MR-CoNS) are important in terms of causing significant nosocomial infections. Besides, MR-CoNS confirmed as the reservoir SCCmec elements that carry mecA (methicillin-resistant) gene. Hence, present study was designed to evaluate susceptibility pattern, prevalence and diversity types I, II, III, IV strains. In this cross-sectional study, 44 clinical isolates were identified using cefoxitin disc method further confirmation by...

MIC bacteriocin nisin was determined using...

Staphylococcus saprophyticus is the second most frequent community-acquired causative agent of acute urinary tract infection (UTI). Some strains S. can create biofilms, increasing their virulence. Once biofilms have been produced, antibiotic resistance exacerbated. Hence, aims present study were biofilm formation, structure and in causing UTIs women Ahvaz, Iran. Overall, 43 isolates recovered from UTIs. Antibiotic pattern production determined using phenotypic methods. Most resistant to...

Ventilator-associated pneumonia (VAP) is a prevalent nosocomial illness in mechanically ventilated patients.

According standard operating method, microbiological laboratory conducts bacteria culture susceptibility testing on endotracheal Tube samples suspected carrying infection. The...

Objective: To evaluate the relationship between biofilm formation and incidence of virulence determinants in clinical isolates Enterococcus.Methods: In this cross-sectional study, Enterococcus strains were collected from university teaching hospitals Ahvaz, Iran June 2017 to 2018. Then, prevalence species, antibiotic resistance, factors, biofilm-producing ability determined.Results: Of 119 tested isolates, 17 (14.3%) faecalis, 72 (60.5%) faecium 30 (25.2%) other spp. Gelatinase was detected...

Background:Staphylococcus epidermidis has emerged as the pathogen from neonatal septicemia. Antibiotic resistance and capability of biofilm formation make these infections much harder to treat. Hence, aim this study was investigate association between formation, structure antibiotic in S. isolated Methods: Overall, 65 isolates were recovered blood cultures pattern production determined using phenotypic methods. The presence ica operon, bhp, aap genes SCCmec types screened PCR. Results: Most...

Background and aim: Currently, the rate of hospital-acquired infections due to drug-resistant Pseudomonas aeruginosa strains shows an increasing trend remains one principal reasons for mortalilty in burn patients. This study aimed investigate prevalence genes conferring resistance carbapenems P. isolates from Methods: A total 50 were tested antibiotic susceptibility presence multidrug-resistant (MDR) extensively drug resistant (XDR) isolates, using phenotypic tests. Screening was...

Tuberculosis (TB) is one of the leading causes mortality among infectious diseases and accounts for a serious health hazard wordwide. Apart from TB, members non-tuberculous mycobacteria (NTM), which includes around 170 species, may also cause different in humans. Therefore this study aimed to investigate distribution NTM strains isolated extrapulmonary (EP) samples by Real-Time PCR PCR-sequencing methods Southwest Iran. Three hundred twenty-five suspected EP were collected patients referred...

One hundred and eighteen sputum specimens suspected of Mycobacterium abscessus infection were collected. Species level identification M. was performed by rpoB sequencing. Clonality analysis done multilocus sequence typing (MLST) for abscessus. Antibiotic susceptibility testing clarithromycin, amikacin, ciprofloxacin moxifloxacin. Altogether 128 isolates obtained subjected to gene sequencing definite identification. Among them 59 identified as abscessus, these included 22 (37.28%) subsp....

Background The drug resistance is expected to be the most important challenge in infection control Iran, where there no local report or standard monitoring system. Therefore, this study aimed investigate aerobic and anaerobic bacterial profile of nosocomial infections their antibiotic Ahvaz, southwest Iran. Methodology gram-positive gram-negative bacteria were identified on basis conventional culture biochemical tests. isolates against antibiotics was determined by disk diffusion method....

Shigella spp. are a major cause of bacillary dysentery, particularly among children in developing countries such as Iran. This study aimed to investigate the presence two important enterotoxins (ShET-1 and ShET-2), encoded by set sen genes, respectively, polymerase chain reaction (PCR) assay species isolated from affected shigellosis Ahvaz, southwest In this cross-sectional study, June 2016 April 2017, altogether 117 isolates were collected fecal specimens aged <15 years with diarrhea All...

Purpose: Dental unit's environment and relevant instruments are a major source of infectious diseases caused by variety microorganisms. The application various disinfectants is one the most effective methods for reducing or eliminating microbial contamination. objective this study was to evaluate antibacterial effects deconex sodium hypochlorite against bacterial taxa isolated from dental Ahvaz Jundishapur University Medical Sciences, southwest Iran. Methods: In order quality disinfection,...

Abstract Burn infection continues to be a major issue of concern globally and causes more harm developing countries. This study aimed identify the aerobic bacteriological profiles antimicrobial resistance patterns burn infections in three hospitals Abadan, southwest Iran. The cultures various clinical samples obtained from 325 patients were investigated January December 2019. All bacterial isolates identified based on standard microbiological procedures. Antibiotic susceptibility tests...

Nocardia species belong to the aerobic actinomycetes group of bacteria which are gram-positive and partially acid-fast Bacilli. These may sometimes be associated with nosocomial infections. diseases not required reported public health authorities in Iran. Hence, present study was designed determine prevalence human spp. Iran by using a systematic review meta-analysis according preferred reporting items for reviews meta-Analyses statement.The data were collected from databases such as Embase,...

Abstract Mycobacterium fortuitum is a clinically important species among nontuberculous mycobacteria (NTM). Treatment of diseases caused by NTM challenging.
