background and objectives: neisseria gonorrhoeae is the second most sexually transmitted diseases agents in developing countries. antimicrobial resistance strains have created serious health concern. the aim of this study was to determine the frequency of endocervical gonococcal infection and antimicrobial susceptibility of n.gonorrhoeae in kashan, iran. materials and methods: in this study, 29...

background and objectives: the emergence of extended-spectrum β-lactamase (esbl)-producing shigella spp.  is of increasing clinical concern specially in children worldwide. the aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing shigella spp. in tehran, iran. materials and methods: the study included all shigella isolates recovered from pediatric patie...

background and objectives: methicillin resistance staphylococcus aureus (mrsa) and coagulase negative staphylococci (mrcons) have recognized as the major cause of nosocomial infections that threat the burn patient’s life. the aims of this study were to determine the frequency of mrsa and mrcons and their antibiotic resistance patterns among burn patients in a burn center in ahvaz, iran. materia...

background: we reviewed the monthly laboratory surveillance reports and hospital laboratory database in dhahira region, oman. methods: all patients for whom a stool sample examination request was made from 1 st january 2002 to 31 st december 2006 (5 years) were included in the study. antimicrobial resistance pattern was studied for 2 years period. the cultures were done using standard laborator...

conclusions periodic evaluation of antimicrobial susceptibility for c. perfringens should be performed. harboring of enterotoxigenic c. perfringens in individuals not necessarily results in diarrhea. results of 136 stool samples including diarrhea [48] and non-diarrhea [88] ones, 83 (61.02%) c. perfringens were cultured. of these 83, 79 c. perfringens isolates showed the alpha-toxin (phospholip...

conclusions: ten percent of the isolates were positive for meca gene among the vancomycin-oxacillin resistant strains, while van gene was not detected in any of the isolates. the data obtained would be useful in clinical control of resistant staphylococcal strains. results: a total of 120 staphylococcus isolates were screened, out of which, 32 (26%) were susceptible to both methicillin and vanc...

background: polycystic ovarian syndrome (pcos) is a common disease among women in fertility ages and cause severe insulin resistance. hyperhomocysteinaemia is said to be among the features of pcos that could influence its outcome. objective: this study aimed to investigate whether hyperhomocysteinaemia exists in pcos and if it is related to insulin resistance in the affected patients. materials...

objectives: to investigate fasting glucose, glucose tolerance, insulin resistance and insulin–like growth factor 1 in patients with or without colorectal polyps. materials and methods: in this cross-sectional study, we evaluated fasting glucose, insulin, insulin–like growth factor 1 (igf-1), lipid profile and glucose tolerance test in 103 patients undergoing colonoscopy (52 normal and 53 with a...

there is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. the objective of this study was to determine the genetic stability of methicillin resistance genes in staphylococcus aureus for the evaluation of resistance strain distribution. one hundred and fifteen s. aureus isolates from patients with staphylococcal infection were collec...

results a total of 18 amoxicillin-clavulanate resistant isolates were obtained from seven different types of retail sausages. only half of them were identified as enterobacteriaceae, but none were esbl-producers. all the 18 isolated strains demonstrated resistance towards amoxicillin-clavulanate, penicillin and oxacillin (100%), cefotaxime (71.4%), cefpodoxime (66.7%), and ampicillin (83.3%). b...
