Althoughpoultry meat is considered as the main source for human Campylobacter infections,there is limited information about non-poultry sources. The present study was aimed to investigate the prevalence and the antibiotic resistance of thermophilic Campylobacter spp. in fecal samples of the cattle and sheep in Shiraz, Iran. A total of 302fecal samples were obtained from clinic...

the first records of anopheles fluviatilis resistance to ddt was reported in 1963 from india and to dieldrin from eastern saudi arabia in 1959. in southern iran, antimalaria measures began in 1950 and up to 1957 the area was under ddt residual house spraying at the rate of 2g /m2 one round/year. during 1958-59 dieldrin was used at 0.5 g/m2, 1or 2 rounds/year was applied in the lowland areas. in...

The source follower circuit is used as a voltage buffer and level shifter. It is more flexible level shifter as the dc value of voltage level can be adjusted by changing aspect ratio of MOSFETs. It is desired to have low output resistance for such applications. Source follower can give minimum output resistance 1/(gm+gmb) with load resistance and channel resistance tending to infinity. The supe...

conclusions this study indicated the contamination of lettuce by stec strains and its possible role as the source of infection. resistance to both tetracycline and ampicillin may be considered as an emergency alarm for a multidrug resistance of stec strains. results eight samples were positive for presence of stec strains, three contained stx1, five contained stx2, and one sample was positive f...

A large amount of resources and effort have been devoted to the development of open source software like Linux. The development of Linux as the most well-known open source software with graphical user interface and useful functionalities is expected to result in the high level of Linux adoption by individual users based on the technology adoption model. However, Linux has about one percent of t...

Background: Increasing resistance of Pseudomonas aeruginosa to ciprofloxacin in ICU/burn units has created a problem in the treatment of infections caused by this microorganism. Methods: Fifty P. aeruginosa strains were isolated from burn patients hospitalized in the Kerman Hospital during May 1999-April 2000 and were tested for in-vitro sensitivity to different antibiotics by disc diffusion br...
