Foot-and-mouth disease (FMD) is endemic in Zambia. Little is known of the epidemiology of FMD virus (FMDV) in the country and this has led to the continuous occurrence of FMD in southern Zambia. FMD severely impacts pastoral and agro-pastoral communities who are most reliant on livestock products for economy and food security. Southern Zambia is densely populated with livestock and wildlife, which are usually in contact almost throughout the year. The control of FMD in Zambia is mainly done strategically through vaccination, but this is complicated by the presence of buffaloes and traditional cattle farmers’ practice of transhumance in areas harbouring wild animals. The current research aims at determining the infection status and FMD virus (FMDV) serotype(s) circulating in domesticated and wild animals in southern Zambia. A targeted cross-sectional study will be employed in this study. Sera and oesophageal-pharyngeal (OP) fluids will be obtained from cattle and buffaloes in selected areas of Zambia. Epidemiological data such as age, sex, health, and vaccination status of animals will be taken during sampling. Infection status will be determined by NSP-ELISA targeting the 3ABC region of FMDV genome. FMDV serotypes will be examined by LPB-ELISA and/or antigen ELISA on OP samples. This research has the potential to unravel the infection status and serotype(s) of circulating FMDV strains in Zambia. This information will be useful in designing a rational strategy of control of FMD in Zambia and the neighbouring countries. © 2014. The Authors. Licensee: AOSIS OpenJournals.

The complement fixation test (CFT), the c-ELISA and an indirect LppQ ELISA were compared to post-mortem (PM) inspection for the diagnosis of contagious bovine pleuropneumonia (CBPP). Sera from 797 cattle in the CBPP affected area of Kazungula, Zambia and 202 sera from Lusaka, Zambia, a CBPP-free area were used. The clinical history of CBPP was recorded and all the cattle from Kazungula were slaughtered and PM inspections conducted. The prevalence of CBPP in Kazungula was 67.5% (95%CI 67.2%, 70.8%), 52.6% (95%CI 49.2%, 56.2%), 59.0% (95%CI 55.5%, 62.4%) and 44.4% (95%CI 41.0%, 47.9%) using PM inspection, CFT, c-ELISA and LppQ ELISA, respectively. Three of the 202 negative control animals tested positive on the c-ELISA although they were from a known CBPP negative zone. In this study, the c-ELISA was more sensitive in detecting cattle with lesions in the chronic stage than any other test whilst the CFT detected more during the onset stage. No single serological test could detect all stages of CBPP infection, therefore the use of more than one test is advised. © 2011 Springer Science+Business Media B.V.

Physocephalus dromedarii stat. nov. was found in the abomasum of two adult female dromedaries originating from a farm in Dubai. Previously, this nematode has been misidentified as a subspecies of Ph. sexalatus but morphological differences are striking enough for it to be upgraded to a species. Physocephalus dromedarii is larger than Ph. sexalatus and has longer spicules. There are 20-22 oblique crests at the ventral surface between the caudal alae of the male compared to 7-8 in the case of Ph. sexalatus. The most significant differences are the presence of two pairs of papillae between cloaca and postcloacal plate of the male and the existence of a swelling in the second half of the female body formed by loops of both uterine horns. © Cambridge University Press 2013.
