The present experiment was conducted to study the effect of ethanolic extract of Egyptian propolis given alone or in combination with inactivated Pasteurella multocida vaccine on rabbits challenged with a virulent strain of Pasteurella multocida. Fifty-six New-Zealand rabbits, 6-8 weeks old and non-vaccinated against pasteurellosis, were randomly divided(More)
This study was conducted to investigate the effect of glycyrrhizin as an immune stimulant against duck hepatitis virus (DHV). In vitro study was carried out to determine cytotoxic and antiviral effects of glycyrrhizin in VERO cells. In vivo study was performed on 40 one-day-old White Pekin ducklings. -and the birds weres divided into 4 groups: control,(More)
Babesiosis threatens the development of the cattle and buffaloes industries in Egypt and improved control is needed. The main objectives of this study are surveying the presence of bovine babesiosis in distinct selected bovine and buffalo populations in Egypt using novel molecular and previously validated serological methods, while also comparing the(More)
The objectives of the present study were to identify a possible tick vector and to determine the prevalence of camel theileriosis in Egypt using blood smears stained with Giemsa’s stain and PCR assay. Hemogram and serum biochemical constituents were also investigated. A total of 243 camels, aged 3–5 years, were examined. The results revealed that 75 (30.86(More)
The present study was conducted to study the protective effect of ethanolic extract of propolis given subcutaneously (S/C) either alone or in combination with inactivated formalized Pasteurella multocida (P. multocida) vaccine in rabbits challenged with virulent P. multocida strain. Twenty-eight New-Zealand rabbits, 6-8 weeks old and not vaccinated against(More)
The present study aimed to investigate the protective effect of glycyrrhizin (locally isolated and purified from licorice root) against duck hepatitis virus through the assessment of some hematological and biochemical parameters. One hundred and sixty white Pekin ducklings-one day old-were randomly divided into four equal groups. Group (1) was kept as(More)
This experiment aimed to evaluate the effect of calcium soap of fatty acid (CSFA) supplementation on serum biochemical and hormones and ovarian activity during out-of-the-breeding season in ewes. Twelve crossbred ewes, 2-3 years of age and weighting 45-55 kg, were allocated into two equal groups. The first group was control and the other was treated with 50(More)
This study was carried out to investigate the effect of long term oral administration of copper pyrazinate at doses of 0.8 and 4.0 mg/kg b.wt. for 10 weeks in rats on copper level in serum, liver and muscle with reference on some haematological and biochemical constituents. LD of copper pyrazinate in mice was 50 also determined. Results revealed that copper(More)
