Infectious Bursal Disease is a highly contagious, immunosuppressive viral disease of young chicks caused by the Infectious Bursal Disease Virus (IBDV). The study was carried out at the National Veterinary Institute (NVI) of Ethiopia to evaluate the competence of the DF-1 cell culture adapted vaccine strain of IBDV as a vaccine candidate. DF-1 cells at passage 27 confluent monolayer was infected with 1 ml of LC-75 vaccine strain virus by adsorption method and recorded as passage 1 (P).

- Peste des Petits Ruminants (PPR) is a disease common in Africa, and effective live attenuated vaccines (Nigeria 75/1 and Sungri/96 strains) are produced to combat it, but maintaining the cold chain for these vaccines is challenging.
- The study assessed the thermotolerance of various stabilizer formulations for freeze-dried and reconstituted PPR vaccines by testing their viability at different temperatures over time.
- Results indicated that the formulation with lactalbumin hydrolysate-sucrose showed the best stability, maintaining vaccine efficacy at higher temperatures, suggesting it should be the preferred stabilizer for vaccines distributed in warmer climates.
Introduction: Humans acquire cystic echinococcosis through accidental ingestion of Echinococcus granulosus (EG) eggs released into the environment by infected dogs. This study aimed to determine the presence of EG antibodies and their determinants in owned dogs in Ibadan, Nigeria.
Methodology: Sera from 185 dogs on routine visits to veterinary clinics were analysed by indirect ELISA.
Arboviruses are important public health threats in many regions of the world. Nigeria has experienced outbreaks of arboviruses over the past decades, leading to concerns of widespread endemicity, which are frequently misdiagnosed. This study aimed to determine the seroprevalence of dengue virus (DENV) (a flavivirus) and chikungunya virus (CHIKV) (an alphavirus) infections in three major population centers of Nigeria.

ASF is believed to currently be enzootic in this region. The status of enzootic transmission of ASF virus strain to pigs is; however, unknown.
