In vitro anticoccidial activity of Thonningia sanguinea extract on Eimeria tenella and Eimeria necatrix sporozoites cell

Avian coccidiosis is a parasitic disease which causes considerable economic loss in poultry. The emergence of anticoccidial drug resistance enhances the need for development of novel approach and alternative controls strategies such as plants extract. The anticoccidial activity of the aqueous extract of Thonningia sanguinea (AE-THOS) was evaluated on Eimeria tenella and Eimeria...

Prevalence of the intestinal parasite infection in cattle in Shaanxi province, northwestern China

A survey of intestinal parasite infection in cattle was conducted in Shaanxi province, northwestern China from November 2010 to January 2012, including Qinchuan cattle and dairy cattle. A total of 1736 fecal specimens (783 and 953 for Qinchuan and dairy cattle, respectively) in 18 farms (including 7 Qinchuan cattle and 11 dairy cattle farms) were obtained. The prevalences of intestinal parasites in Qinchuan cattle were...

Molecular evaluation of hepatitis G virus and hepatitis C virus in patients with chronic renal failure in Iran

Prevalence rates of hepatitis G virus (HGV) and hepatitis C virus (HCV) are high in people who have received regular blood transfusion. Patients with chronic renal failure carries are susceptible to acquiring blood borne virus infections, especially viral hepatitis. The aim of this study was to define the actual prevalence of HCV and HGV in Iranian hemodialysis (HD) patients. This cross sectional-descriptive study the...

Host specificity of endophytic Pestalotiopsis populations in mangrove plant species of South China

For the fact that mangrove plant species are a valuable reservoir of useful metabolites, their endophytes have received increasing attention. We examined the distribution of endophytic Pestalotiopsis associated with mangrove forest from three locations (Guangdong, Fujian, and Hainan province) in South China. Colonization frequencies ofendophytic Pestalotiopsis varied with the place of mangrove plants...

Macro-restriction analysis of Staphylococcus aureus isolated from subclinical bovine mastitis in Nigeria

Different pathogens cause both clinical and subclinical mastitis and Staphylococcus aureus is the most common. One hundred and thirty six apparently healthy cows from six Local Government Areas of Plateau state, Nigeria were sampled for the isolation of this pathogen. Three hundred and thirty nine quarter milk samples from the cows were collected, out of which 102 S. aureus were isolated. Twenty...

Isolation of amylase producing aquatic actinomycetes from the sediments of mangrove forests in south of Iran

Recent researches have shown that aquatic actinomycetes can be important source to discover biological products including amylase. Amylase is one of the important enzymes in industry. In this study aquatic actinomycetes producing amylase were isolated from the sediments of mangrove forests in south of Iran and the rate of amylase activity was measured. The samples were collected from one hundred different places in...

Study and comparison of the bacterial contamination outbreak of chicken meat consumed in some cities of Mazandaran Province (Iran)

Since meat is the richest protein source and plays an important role in the transmission of bacteria, especially Zeonosis to humans, the pathogenic bacteria outbreaks such asSalmonella, Campylobacter, Yersinia, and Aeromonas in the packed and unpacked chicken meat supplied to some cities of Mazandaran province of Iran performed, which have not been examined and analyzed yet. 200 samples of chicken...

Prevalence of coccidiosis and other gastointestinal nematode species in buffalo calves at Hyderabad, Sindh, Pakistan

A total of 1000 bovine feacal samples were randomly collected per-rectum from Hyderabad and its surrounding areas to determine the types and prevalence of coccidian parasites. Coccidian oocysts were found in 6.6% of all samples examined. Eimeria bovis66 (6.6%) was the most prevalent species in the buffalo calves. During the present investigation four species of nematodes were also identified. The species...

Inactivation of Tobacco mosaic virus in soil by Pseudomonas putida A3-m strain to prevent virus mosaic disease

Previous studies showed that Pseudomonas putida A3-m exhibited a strong antiviral activity against Tobacco mosaic virus (TMV) in tobacco. However, its potential effect on the amount of TMV in the soil remains unknown. In this study, all plants in two treatments and the control did not have significant differences in terms of height and fresh weight at 20 and 30 days after transplanting. And the effect of...

Characterization of siderophore producing bacterial strain Pseudomonas fluorescens Mst 8.2 as plant growth promoting and biocontrol agent in wheat

A set of 28 Pseudomonas bacterial strains were examined for siderophore production by chrome azurol sulphonate (CAS) assay. Among the 28 strains tested, 14 were found to be siderophore producers. These strains were evaluated for their biocontrol potential againstRhizoctonia solani using various dual culture assays. The role of siderophores in the inhibition of R. solani was confirmed by iron...
