Research ArticleOpen accessIn the abstractAlterations in Interleukin-1β and Interleukin-6 in Mice Inoculated Through the Oral Routes Using Graded Doses of p. Multocida Type b: 2 and its LipopolysaccharideOmar Suwaidan Ali, Lawan Adamu, Faez Firdaus Jesse Abdullah et al.The gram-negative bacterium Pasteurella multocida serotype B: 2 is an important veterinary and opportunistic human pathogen that causes deplorable welfare problems and colossal economic production losses in bovine and other animal species throughout the world. Pasteurella multocida type B: 2 and its LPS are associated with Haemorrhagic Septicaemia (HS) in mice as animal model. Sixty healthy Balb c mice were … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 22 Dec 2014 · 7,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractHISTOPATHOLOGICAL CHANGES IN MICE INFECTED WITH RIVER WATER CONTAMINATED BY PASTEURELLA MULTOCIDA TYPE B:2Mohammed Muqdad Khaleel, Faez Firdaus Jesse Abdullah, Lawan Adamu et al.Haemorrhagic Septicaemia (HS) is a fatal systemic disease of bovines typified by an acute, highly fatal septicaemic disease with high morbidity and mortality. In this study, sixty five adult ICR mice were used for the study. In the first phase, 5 mice each were inoculated with 109 cfu of P. multocida type B:2 through the intraperitoneal route. After development of … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 2 · 28 Mar 2014 · 7,758 accessesView PDFCite
