Diseases of indigenous chickens in Bokaa village, Kgatleng district, Botswana

Abstract

his study examined flock size and management, level of internal and external parasite burden and seroprevalence of antibodies to poultry pathogens in indigenous chickens in Bokaa village, Kgatleng district, Botswana. The mean flock size was 22.6±6.85 with a range of 11-34. The mean body weights of cocks and hens were 2.28±0.56 kg and 1.70 ±0.38 kg, respectively. Housing and commercial poultry feed were not provided. Ascaridia galli, Heterakis gallinarum and Syngamus trachea were found in some birds. Although the chickens were not vaccinated against any poultry diseases, serum antibodies to Newcastle disease, infectious bursal disease and infectious bronchitis were detected

Avian infectious bronchitis virus in Africa: a review

“…The same was true for Botswana, where the circulation of IBV through serological analysis revealed the presence of antibodies to IBV in unvaccinated poultry farms (Mushi et al 2006).…”

Molecular characterisation of infectious bursal disease virus in Namibia, 2017

“…Given the similarity of the Namibian samples with IBDV from Zambia, as shown by the phylogenetic analysis, the two countries may also share a common origin or source of the virus. Nonetheless, given that there is no published genetic data on IBDV available from Angola, or for that matter from Botswana or Zimbabwe, despite disease occurrence being reported (Kelly et al 1994; Mushi et al 2006), no conclusion can yet be made on the origin of the IBDV investigated in this study.…”

Current situation, genetic relationship and control measures of infectious bronchitis virus variants circulating in African regions

“…It was described and recognized for the first time in North Africa, especially in Egypt since 1950s (Eissa et al, 1963), from birds showing respiratory signs and confirmed by Eissa et al (1963), in Morocco in 1983(El Houadfi and Jones, 1985, in Tunisia between 2009 and 2013 (Bourogaˆa et al, 2009), in Libya in 2012(Awad et al, 2014, and in Algeria (Sid et al, 2015). Antibodies against the IBV were reported from South Africa with 43% of IB prevalence in QwaQwa (Thekisoe et al, 2003), 86% in Chitungwiza, Zimbabwe (Kelly et al, 1994), and in Botswana (Mushi et al, 2006). Up to now little is known about the distribution and impact of IBV in sub-Saharan African countries including Ivory-Coast.…”
