in the present study 220 diarrheal samples of children aged between 3-12 months and 100 samples from healthy individuals of the same age group reffered to Shiraz university hospitals were investigated for bacterial and viral agents.Electron microscopy methods were used for the viral investigations,while conventional techniques of bacteriology were used for isolation of bacterial agents.the prev...

This study was undertaken to determine the prevalence and diversity of Eimeria species in sheep in Tabriz suburb. The prevalence of ovine parasitism due to Eimeria spp. was estimated in 240 sheep aged less than six months to over 12 months, in a period of one year (2003-2004). The samples were collected from pre-slaughtered sheep in Tabriz slaughterhouse and transferred to the parasitology labo...

equine piroplasmosis is a severe disease of horses caused by the intra-erythrocyte protozoan, theileria equi and babesia caballi. the aim of this study was to identify equine piroplasmosis based on molecular and morphometrical features in horses in suburb of urmia, west azerbaijan province, iran. from april to september 2011, a total number of 240 blood samples were collected randomly from hors...

Helicobacter pylori (H. pylori) infection is closely related to various gastroduodenal diseases. Virulence factors and bacterial load of H. pylori are associated with clinical outcomes, and drug-resistance severely impacts the clinical efficacy of eradication treatment. Existing detection methods are low-throughput, time-consuming and labor intensive. Therefore, a rapid and high-throughput meth...

Pneumoenteric lesions of Colisalmonellosis in poultry cause high mortality and morbidity with resultant production failure. In the present study, 500 samples were collected from broilers. 106 samples revealed bacterial causes for pneumonia and 22.7 per cent of the pneumonic lesions were found to be mixed infection of E.coli and Salmonella. 60 samples indicated bacterial enteritis and 30.77 per ...

the purpose of this study was to determine the therapeutic efficacy of citric and tartaric acids on experimental dermatophytosis in guinea pigs. in this study, the susceptibility of trichophyton mentagrophytes var. mentagrophytes to citric and tartaric acids was assessed using the macrodilution broth method. in the animal experiments, a cream consisting of the mixed acids was topically applied ...

Hepatitis C virus (HCV) genotypes may be investigated by a variety of laboratory methods that target different parts of the HCV genome and have various degrees of technical difficulty. Since the choice of a particular method is difficult, we compared the performance of (i) a type-specific PCR with type-specific primers from the core region, (ii) molecular hybridization of the PCR-amplified 5' n...

Because a close relationship has been established between mixed cryoglobulinemia and hepatitis C virus (HCV) infection, the clinical, histologic, and virologic findings of 31 patients affected by mixed cryoglobulinemia have been determined. HCV infection was investigated by the presence of anti-HCV antibodies and by polymerase chain reaction (PCR) amplification of the 5' untranslated region (5'...

introduction malaria is the most important parasitic infection, which is now spread all over the globe. malaria infections with more than two species, especially plasmodium falciparum and p. vivax, are common, but infections with p. malariae and p. falciparum are rare. discussion mixed malaria infection is not uncommon, and it needs to be diagnosed and treated effectively in order to control th...
