Experimental vaccination of sheep against hydatid cyst using EG95 recombinant vaccine

Vaccination of livestock with effective vaccine could be one of the control methods for hydatid cyst. In this study a new recombinant vaccine (Eg95) from New Zealand was prepared and used. Thirty health sheep from the same race and identical age and sex were selected. There was no history of any past vaccination or disease in selected animals. Animals were randomly categorized to four groups. O...

Experimental vaccination of sheep and cattle against tick infestation using recombinant 5′-nucleotidase

Limited prior evidence suggests that 5'-nucleotidase, an ectoenzyme principally located in the Malpighian tubules of the tick Rhipicephalus (Boophilus) microplus, could be an effective antigen in an anti-tick vaccine. To assess this, recombinant 5'-nucleotidase was expressed in Escherichia coli and used in vaccination trials with both sheep and cattle. Vaccinated sheep were challenged with fres...

Vaccination of Chicks with an Experimental Oil-emulsion Vaccine against Infectious Bursal Disease Virus

Correlation between age of sheep and structural changes of sheep hydatid cyst

BACKGROUD: Naturally, the prevalence of hydatid cyst of sheep increase with age and accompany with structural changes. OBJECTIVES: The aim of the present study was to determine prevalence of hydatid cyst in sheep and its structure with age. METHODS: During 2009, 786 sheep in different age groups (1 to 6“ |years) slaughtered at Babol abattoir, Mazanderan province were examined for hydatid cyst ...

Purification and Immunobiochemical Characterization of Sheep Hydatid Cyst Fluid Antigen

In the present study, sheep crude hydatid cyst fluid antigen (SCHCFA) was prepared by ammonium sulfate precipitation, centrifugation and dialysis. SDS-PAGE of SCHCFA showed seven polypeptides of 72.8 kDa, 66.5 kDa, 60.2 kDa, 41 kDa, 25.1 kDa, 19 kDa and 8 kDa when stained with Coomassie briliant Blue R-250. The initial part of the ascending loop of the first peak (PI) when resolved by gel filtr...

Protection of sheep against Rift Valley fever virus and sheep poxvirus with a recombinant capripoxvirus vaccine.

Rift Valley fever (RVF) is an epizootic viral disease of sheep that can be transmitted from sheep to humans, particularly by contact with aborted fetuses. A capripoxvirus (CPV) recombinant virus (rKS1/RVFV) was developed, which expressed the Rift Valley fever virus (RVFV) Gn and Gc glycoproteins. These expressed glycoproteins had the correct size and reacted with monoclonal antibodies (MAb) to ...
