a total of 183 coagulase negative staphylococcal infected quarters and 64 uninfected quarters were randomly allotted to 4 experimental groups: infected quarters that did not receive any treatment (positive control group; n = 60); infected quarters that received tylosin (n = 61) or cefquinome (n = 62) and also uninfected quarters that did not receive any treatment were considered as negative con...

disseminated tuberculosis (tb) is commonly seen in hiv-infected patients and is major cause of death in these patients. in hiv-infected patients disseminated tuberculosis is frequently undiagnosed or misdiagnosed. in this article we report a case of disseminated tb in a hiv-infected patient with a relatively long history of fever and other complaints without definite diagnosis. diagnosis of dis...

We used a freshwater amphipod-microsporidian model (Ponto-Caspian hosts: Dikerogammarus villosus and D. haemobaphes , parasite: Cucumispora dikerogammari ) to check whether parasites affect biological invasions by modulating behaviour intra- interspecific interactions between the invaders. tested competition for shelter in conspecific heterospecific male pairs (one or both individuals infected ...

the infection of food animals to hydatid cyst is a concern from economic and public health stand points. in this survey, the prevalence of hydatid cysts was studied in 547 buffaloes slaughtered at the slaughterhouse in urmia. samples from 58 cases (10. 6%) were infected to hydatid cysts. the infection rates of lung and liver were 45 cases (77. 5%) and 37 cases (63. 7%), respectively, while each...

background and aims: infectious bronchitis (ib), caused by infectious bronchitis virus (ibv), is an acute and highly contagious disease in chickens. ibv is considered mainly as a respiratory infection, other clinical manifestations, including renal, enteric and reproductive signs can be observed. since there has been no study on evaluation of changes in biochemical parameters during ib infectio...

evidence has shown that liver disease caused by hepatitis viruses can be more aggressive and severe in hiv infected subjects. therefore, the present cross-sectional study aimed to evaluate the seroprevalence of hdv infection among hiv/hbv co-infected clients in shiraz, southwest iran. in this study, 178 patients co-infected with hbv and hiv individuals were enrolled. the diagnosis of hiv infect...

Abstract BACKGROUND: In vitroexperiments in which HIV-infected CD4 +T cells are co-cultured with natural killer (NK) yield incomplete elimination of the infected cells. We therefore hypothesize that cell-intrinsic pathways differentially regulated to mediate resistance NK cell-mediated killing. METHODS: Mock-infected and HIV-89.6-infected from 6 HIV −donors were overnight +/− autologous Followi...

Cryptosporidium is a protozoan parasite that infects epithelial cells of the intestine in a wide variety of vertebrates. During the last decade, cryptosporidiosis has emerged as a cause of diarrhea in man. Most of the' patients have AIDS, and have had contact with infected animals. In this study ' 510 samples were collected from sheep and examined for detection of this parasite. The result...

background : in this experiment, abdominal cavity of 518 iranian sistani cattle and 498 brahman cattle were inspected for the presence of setaria spp. from april 2012 - may 2013. methods: the species were determined by microscopic examination of the mor-phological characteristics of the anterior and posterior parts of the parasites and authentic guidelines. results: the overall prevalence of se...
