Njau, Emma; Machuka, Eunice; Cleaveland, Sarah; Shirima, Gabriel; Kusiluka, Lughano; Okoth, Edward; Pelle, Roger (MDPI, 2021-11-15)African swine fever (ASF) is a highly infectious and fatal haemorrhagic disease of pigs that is caused by a complex DNA virus of the genus Asfivirus and Asfarviridae African suids family. The disease is among the most ... -
Association of LEI0258 Marker Alleles and Susceptibility to Virulent Newcastle Disease Virus Infection in Kuroiler, Sasso, and Local Tanzanian Chicken Embryos.
Mpenda, Fulgence; Tiambo, Christian; Kyallo, Martina; Juma, John; Pelle, Roger; Lyantagaye, Sylvester; Buza, Joram (Hindawi, 2020-04-08)Newcastle disease (ND) control by vaccination and an institution of biosecurity measures is less feasible in backyard chicken in developing countries. Therefore, an alternative disease control strategy like the genetic ... -
