The full genome sequence (19,177 bp) of an Indian strain (IND1988/02) of bluetongue virus (BTV) serotype 23 was determined. This virus was isolated from a sheep that had been killed during a severe bluetongue outbreak that occurred in Rahuri, Maharashtra State, western India…

MicroRNAs (miRNAs) are small, abundant, non-coding RNAs that modulate gene expression by interfering with translation or stability of mRNA transcripts in a sequence-specific manner. A total of 734 precursor and 996 mature miRNAs have so far been identified in the chicken…

This chapter discusses the up-to-date literature on historical distribution, virus and disease, classification, viral replication, pathogenesis, clinical signs, gross lesions, disease transmission, other avian paramyxovirus serotypes and laboratory diagnosis of Avian…

A method has been established to sequentially delete combinations of genes from the ASFV genome to test the effect on virus replication and host responses to infection. Initially the ASFV genes MGF505 2R and MGF505 3R and a truncated MGF360 9L gene were deleted from the…

The epidemiology of foot-and-mouth disease (FMD) in North Africa is complicated by the co-circulation of endemic FMD viruses (FMDV), as well as sporadic incursions of exotic viral strains from the Middle East and Sub-Saharan Africa. This report describes the molecular…

As well as being vectors of many viral, bacterial, and protozoan pathogens of medical and veterinary importance, ticks harbour a variety of microorganisms which are not known to be pathogenic for vertebrate hosts. Continuous cell lines established from ixodid and argasid…

Tick cell lines play an important role in research on ticks and tick-borne pathogenic and symbiotic microorganisms. In an attempt to derive continuous Dermacentor reticulatus cell lines, embryo-derived primary cell cultures were set up from eggs laid by field ticks…

Background: Eimeria tenella is an apicomplexan parasite that causes coccidiosis in the domestic fowl. Infection with this parasite is diagnosed frequently in intensively reared poultry and its control is usually accorded a high priority, especially in chickens raised for…

Background: The olive fruit fly, Bactrocera oleae, is the major arthropod pest of commercial olive production, causing extensive damage to olive crops worldwide. Current control techniques rely on spraying of chemical insecticides. The sterile insect technique (SIT) presents…
