considering the circulation of bordetella pertussis clinical strains among populations with high vaccination coverage, it is necessary to have a proper understanding of this bacterium causing whooping cough. various techniques, which are available for studying b. pertussis, can facilitate a proper comparison between different populations. we genotypically analyzed a collection of two vaccine st...
Considering the circulation of Bordetella pertussis clinical strains among populations with high vaccination coverage, it is necessary to have a proper understanding of this bacterium causing whooping cough. Various techniques, which are available for studying B. pertussis, can facilitate a proper comparison between different populations. We genotypically analyzed a collection of two vaccine st...
Background and purpose: Haemophilus influenzae type b (Hib), is one of the major causes of bacterial meningitis in children younger than five years of age, especially in countries that immunization against Hib is not conducted. In this study we have determined the serotype, encapsulated Haemophilus influenza strains isolated from clinical samples by polymerase chain reaction (PCR) method. Mater...
Background and Aim: Ciprofloxacin-resistant Salmonella spp. are among the most important causative agents of food-borne infections. The marA efflux pump in this bacterium plays a significant role in the development of drug resistance. The aim of this study was to investigate marA efflux pump gene expression in Ciprofloxacin resistant Salmonella enteritidis clinical strains by Real Time PCR. Mat...
Introduction: There are various virulence factors encoded by Staphylococcus Aureus, which enable them to cause nosocomial infections and mastitis in dairy cattle. The clf-A gene mediates the bacterial colonization through binding to the extracellular matrix of the host. Treatment of such infections becomes more difficult due to increased resistance to methicillin. The current study aimed at inv...
background: re-emergence of pertussis has been reported in iran despite a high rate of vaccination coverage. low efficacy of the vaccine might be due to the genetic divergence between clinical versus vaccine strains. in the current study, the genetic profiles of clinical isolates and vaccine strains of bordetella pertussis (b. pertussis) were assessed by using pulsed field gel electrophoresis (...
A study was performed to determine the species and antimicrobial susceptibility of 100 enterococcus strains from various clinical specimens as etiological agents at the Clinical Microbiology Laboratory, Istanbul University, Medical Faculty Hospital. Out of 100 enterococcal isolates, 86 were identified as E. faecalis, 11 as E. faecium, 1 as E. avium and 2 as E. raffinosus. By the disk diff...
conclusions the clinical klebsiella strains isolated from lahore region, pakistan exhibited resistance to most commonly used antibiotics, which can be a serious threat to public health. the study reported some potential actinomycetes strains, which exhibit promising activity against multidrug resistant klebsiella strains. results the isolated klebsiella strains showed resistance against most of...
