Antisera produced in rabbits immunized with an enteroinvasive O143 strain of Escherichia coli were absorbed with an avirulent derivative of the same strain. The resulting sera have been previously shown to recognize enteroinvasive pathogens when used in an enzyme-linked immunosorbent assay. In the current study, Western blots (immunoblots) showed that such an absorbed rabbit antiserum recognize...

Single injections of morphine induce a state of acute opioid dependence in humans and animals, measured as precipitated withdrawal when an antagonist is administered 4-24 h after morphine. Additional morphine exposure at daily or weekly intervals results in further increases in withdrawal severity, suggesting that acute opioid dependence reflects the early stages in the development of a chronic...
The virulence of the human pathogen Shigella flexneri is dependent on both chromosome- and large-virulence-plasmid-encoded genes. A kanamycin resistance cassette mutation in the miaA gene (miaA::Km Sma), which encodes the tRNA N6-isopentyladenosine (i6A37) synthetase and is involved in the first step of the synthesis of the modified nucleoside 2-methylthio-N6-isopentenyladenosine (ms2i6A), was ...
Bacillary dysentery caused by Shigella species is a public health problem in developing countries including Bangladesh. Although, shigellae-contaminated food and drinks are often the source of the epidemic's spread, the possible presence of the pathogen and transmission of it through environmental waters have not been adequately examined. We analyzed surface waters collected in Dhaka, Banglades...
عفونت های اسهالی یکی از شایعترین بیماری ها در سراسر جهان هستند.دو جنس shigella و escherichia اعضای مهم خانواده انتروباکتریاسه ها ( enterobacteriaceae) و عامل اصلی اسهال های عفونی می باشند. شیگلا از طریق تهاجم به سلول های اپی تلیال روده باعث ایجاد اسهال وشیگلوزیس می شوند.یکی از کلیدی ترین پروتئین هایی که در تهاجم نقش دارد ipac است. باکتری های دیگری از جمله etecو ehecاز جمله عوامل عمده در ایجاد ا...
