background and purpose: by using advanced detection/identification methods, the list of emerging uncommon opportunistic yeast infections is rapidly expanding worldwide. our aim in the present study was sequence-based species delineation of previously unidentified yeasts obtained from a clinically yeast collection. materials and methods: a total of twenty three out of the 855 (5.7%) yeast isolat...

conclusions the results of this study showed that pcr–rflp technique was a fast and applicable method especially for separation, detection and differentiation between species of b. melitensis and b. abortus biovars in blood sample. also the presented data showed that b. melitensis biovar 1 was the prevalence biovar. background brucella is an intracellular parasite of the disease brucellosis thr...

background and objective: shigella species belong to the family enterobacteriaceae, which cause dysentery with abdominal pain and tenesmus in human. our country is one of the endemic and occasional epidemic areas of the disease. in the present study, repetitive extragenic palindromic polymerase chain reaction (rep-pcr) technique that has high differentiation and specificity power compared to ph...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

abstract        typing of bacteria is an important part of epidemiological studies on nosocomial infections. bacterial identification methods have dramatically improved in recent years, which is mainly due to advancements in the field of molecular biotechnology. in many cases, molecular techniques have replaced phenotypic typing methods. currently, a wide range of bacterial typing techniques is...

conclusions the inter- and intra-hospital dissemination of resistant clones is a matter of concern and is an indicator of the level of the improvement and surveillance of standard hygiene, particularly disinfection and hand washing before and after contact with patients. given the emergence of mbl-producing strains, surveillance has become an important procedure to control the transmission of r...

background methicillin-resistant staphylococcus aureus (mrsa) remains a significant public health problem and treatment challenge. objectives this study was conducted to determine the frequency, molecular types, and drug resistance of s. aureus isolated from nasal carriers in two teaching hospitals (hajar and kashani) in shahrekord, southwestern iran. methods in this cross-sectional study, 262 ...

background: linear dermatitis is endemic in iran where most cases occur in the caspian sea coast and fars prov­ince. the disease is caused by beetles of the genus paederus which are active from early spring to beginning of au­tumn although its incidence rises from may to august. the classic taxonomy of paederus spp. is based on the male genitalia that is very complex and needs expertise. in thi...
