results amongst 938 stool samples, 36 were shigella spp. s. sonnei (61.1%, n = 22), which was the most common, followed by s. flexneri (27.8%, n = 10), s. boydii (8.3%, n = 3), and s. dysenteriae (2.8%, n = 1). furthermore, most shigella isolates showed resistance to amoxicillin (83.3%), tetracycline (61.1%), and co-trimoxazole (83.3%). no resistance was found against ciprofloxacin and imipenem...

background evidence indicates that insulin resistance results in poor sustained viral response (svr) in patients with chronic hepatitis c (chc). metformin is an oral hypoglycemic agent which improves insulin resistance. methods we sought to determine if the addition of metformin to the treatment regimen could improve svr in treatment-naive chc patients in a randomized, double-blind, placebo-con...

background : insecticide resistance is one of the serious problems for german cockroach control program. this study was conducted to determine the bendiocarb and carbaryl resistance mechanisms in german cockroaches using the piperonyl butoxide (pbo). methods : bioassay tests were conducted with 4 to 6 different concentrations of both insecticides with four replicates of 10 susceptible strain co...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.
