cockroaches were collected from hospitals, houses and poultry sheds in various parts of isfahan (iran) and identified to species. in total, seven species of cockroaches in seven genera were identified: blatta lateralis, polyphaga aegyptiaca, arenivaga roseni and parcoblatta spp. three species periplaneta americana, blattella germanica and supella longipalpa (blattidae and blattellidae) were mor...

background: multi drug resistant (mdr) pseudomonas and acinetobacter species are defined as resistant to at least three classes of antibiotics. most studies have demonstrated that mdr gram negative infections convey increased mortality and morbidity. case: an 11-year –old girl was admitted to pediatric burns unit with burn injury of approximately 68% total body surface area (tbsa). discussion: ...

The emergence of influenza drug resistance has become of particular interest as current planning for an influenza pandemic involves using massive amounts of antiviral drugs. We use semi-stochastic simulations to examine the emergence of drug resistant mutants during the course of a single infection within a patient in the presence and absence of antiviral therapy. We specifically examine three ...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

To determine whether women in KwaZulu-Natal, South Africa, with drug-resistant tuberculosis (TB) were more likely than men to have extensively drug-resistant TB, we reviewed 4,514 adults admitted during 2003-2008 for drug-resistant TB. Female sex independently predicted extensively drug-resistant TB, even after we controlled for HIV infection. This association needs further study.
