this study was carried out to control johne’s disease (jd) without interfering with tuberculosis (tb)control programme. a dairy herd (n>1500 heads) was used over a period of 6 years, from 1994 to 1999 forthis investigation. the herd had a history of heavy infection with mycobacterium avium paratuberculosis(map) with culling rates of 1.5 and 5%, in 1991 and 1995, respectively. the mean annual lo...

Avian Pasteurella multocida is the causative agent of fowl cholera, a disease much affecting the poultry industry. In order to study the efficacy of the recombinant subunit vaccine constructed with ptfA gene of avian P. multocida, the ptfA gene fragment amplified by PCR from avian P. multocida was cloned into the prokaryotic expression vector pET32a and the recombinant plasmid pET32a-ptfA was o...

shigella species (spp.) are gram-negative bacteria that are responsible for shigellosis. although it can be controlled via antibiotics, increasing number of antibiotic resistant isolates of shigella have been reported. therefore, other strategies such as production of specific vaccine against this organism could be a suitable therapeutic approach. attenuated live vaccines produced by gene delet...

Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were ...

avian pasteurella multocida is an agent of fowl cholera. the protective effect achieved through orthodoxvaccines is not ideal. the research on novel vaccines against avian pasteurella multocida is imperative. inthis study, the genes encoding outer membrane protein h and a (omph and ompa) were cloned into theeukaryotic expression vector pcdna3.1(+) and the recombinant plasmids, namely dna vaccin...
