introduction: listeria monosytogenes is a gram-positive organism, frequently found in the environment and is responsible for serious food-born diseases such as perinatal infections, septicaemia and meningoencephalitis in humans and animals. materials & methods: distribution of the ctpa determinant among l. monosytogenes isolated from environmental and clinical samples was investigated using pcr...
Background: The nosocomial infections that cause the establishment of biofilms on the embedded biomedical surfaces are the leading cause of sepsis and are often related to colonization of implants by Staphylococcus epidermidis. Materials and Methods: A total of 40 clinical S. aureus isolates were collected from Zabol, Iran. The ability of these strains to form biofilm was determined by microli...
Background: Pseudomonas aeruginosa is an important opportunistic pathogen causes clinical infections among burn patients. Metallo-β-lactamases (MBLs) are important mechanisms of Carbapenem (drug of choice) resistance among Pseudomonas aeruginosa isolates. The aims of this study were to determine the antibiotic susceptibility pattern and to detect the prevalence of MBLs among Pseudomonas aer...
Background: Stenotrophomonas maltophilia is an opportunistic bacterium, contributing to different hospital-acquired infections and can be acquired from different hospital setting sources. Epidemiological study of S. maltophilia in the hospital also demonstrates the intrahospital distribution of certain strains of bacteria in healthcare facilities. The aim of the current study was to identify th...
Background and Aims: Pistacia atlantica is one of the medicinal plants native to Iran and known for its antimicrobial properties. Therefore, the present study aimed to investigate the antibacterial and antifungal effects of the aqueous extract of P. atlantica leaves on clinical isolates of Escherichia coli and Candida albicans in vivo. Materials and Methods: In this descriptive-cross-sectional...
Background and purpose: Invasive aspergillosis (IA) is a leading cause of morbidity and mortality in patients with decreased immune status. Aspergillus flavus is the second most common species causing invasive aspergillosis after A. fumigatus. According to limited information on the antifungal susceptibility test against A. flavus in Iran, in this study we aimed at evaluating the antifungal sus...
Background: Cefepime was used as empirical treatment in ventilator-associated pneumonia (VAP) induced by gram-negative and gram-positive bacteria. This study aimed to determine the antimicrobial susceptibility pattern of cefepime against microorganism causing VAP in Mazandaran, North of Iran. Methods: This study was performed on VAP patients diagnosed with clinical pulmonary infection score (CP...
Frequency of E. coli clinical isolates producing blaSHV and blaTEM extended-spectrum beta-lactamases
Introduction: Production of extended-spectrum beta-lactamase enzymes (ESBLs) in E. coli creates many problems for patients. These enzymes are located on transferable elements and can hydrolyze penicillins, broad-spectrum cephalosporins, and aztreonam. This study aimed to determine the clinical isolates of E. coli producing ESBLs of blaSHV and blaTEM in the city of Zanjan. Methods: This cross...
Abstract Background and Objective: Staphylococcus aureus is an important opportunistic pathogen causing a wide range of infections in human .Most clinical isolates of S.aureus are resistant to a number of antibiotics. For appropriate antimicrobial therapy, this study was conducted to determine antibacterial drug resistance patterns of S.aureus isolates obtained from different clinical samp...
Background & Aims: Nowadays, the common use of azoles has led to increased resistance to azole among Candida albicans strains. Amino acid substitutions in azole target enzyme, ERG11p, is attributed to azole resistance in some clinical strains of Candida albicans. The aim of this study was to evaluate ERG11 gene mutations in fluconazole-resistant isolates of Candida albicans in Rasht. Materials...
