background: multidrug resistance in salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. methods: salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to pcr and identified as salmonella enteritidis. for detection and identi...

background :    acinetobacter baumannii has become one of the most important causes of nosocomial infections in recent years. the organism seems to be resistant to most classes of antibiotics. carbapenems are considered the most effective drugs for treatment of these infections. however, increasing emergence of carbapenem resistant a. baumannii has become a major healthcare problem.   methods :...

conclusions according to the findings of our study, there were diverse and high-level resistant p. aeruginosa strains in the major burn center in khuzestan. therefore, we faced troubles controlling the diverse p. aeruginosa clones in the burn patients. methods in a cross sectional study, a total of 75 strains of p. aeruginosa were isolated from burn patients at taleghani hospital, which is the ...

background and objectives: the global spread of methicillin resistant staphylococcus aureus (mrsa) constitutes one of the most serious contemporary challenges to the treatment of hospital-acquired infections. we aimed to screen and assess the antibiotic susceptibility pattern of staphylococcus aureus isolated from clinical specimens in local hospitals of northern province in jordan. materials a...

background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...

streptococcus pneumoniae is an important problem worldwide and nasopharyngeal colonization plays significant role in pneumococcal infections. the aims of this study were to determine the nasopharyngeal colonization rate, serotyping, antibiotics susceptibility and study the risk factors for nasopharyngeal colonization with s. pneumoniae in students in kashan, iran.a cross-sectional study was con...

shigella sonnei is considered as a major cause of diarrheal disease in both developing and developed countries. iran is one of the endemic areas of shigellosis. the present study was undertaken to investigate the antibiotic susceptibility and genetic relatedness of s. sonnei strains isolated from pediatric patients in tehran, iran.the study included all s. sonnei strains isolated from pediatric...

results two bacterial types, st208, and st218, were identified in all 140 samples. the st208 mainly came from icu and department of respiratory medicine, while st218 from department of plastic surgery; 70.21% of st208 and 84.78% of st218 were carbapenem-resistant acinetobacter baumannii (crab) and carbapenem-susceptible acinetobacter baumannii (csab), respectively. multidrug-resistance genes in...
