Distribution and prevalence of ticks and tick-borne pathogens of wild animals in South Africa: A systematic review

Ticks are significant ectoparasites of animals and humans. Published data indicate that most vectors that transmit livestock and human pathogens in sub-Saharan Africa, are native to the region and originate from wild animals. Currently, there is a paucity of information on the role of wild animals on the epidemiology of zoonotic tick-borne pathogens in South Africa. This systematic review focuses on the distribution of ticks and prevalence of tick-borne pathogens in different wild animals in South Africa to identify potential

Peste des Petits Ruminants Virus Infection at the Wildlife–Livestock Interface in the Greater Serengeti Ecosystem, 2015–2019

Peste des petits ruminants (PPR) is a viral disease of goats and sheep that occurs in Africa, the Middle East and Asia with a severe impact on livelihoods and livestock trade. Many wild artiodactyls are susceptible to PPR virus (PPRV) infection, and some outbreaks have threatened endangered wild populations. The role of wild species in PPRV epidemiology is unclear, which is a knowledge gap for the Global Strategy for the Control and Eradication of PPR. These studies aimed to investigate

Anatomical characteristics of the larynx in giraffe (Giraffa camelopardalis)

In the present study, the most outstanding anatomical findings of the larynx of a giraffe are described. The larynx obtained from a male necropsied animal was studied following fixation in a 10% formaldehyde solution. There was no rostral horn in the thyroid cartilage and so cranial thyroid fissure was almost smooth or hardly visible concave structure. Caudal horn was short and caudal thyroid fissure was very depth. Lateral surface of arytenoid cartilage possessed a well-developed oblique arcuate crest between corniculate

Genetic Markers in Wild Animal Studies

A survey is given of the work performed in the Onderstepoort laboratory on the studies of genetic markers in wild animals. The implications of using genetic markers reflecting single gene changes in animal studies are discussed. Preliminary results indicate that certain wild animal populations are genetically less variable than others, and the consequences are discussed. If this phenomenon should be substantiated by further investigations, then certain corrective measures to ensure the survival of certain animal groups or even species would

Reproductive failure in female Thornicroft’s giraffe (Giraffa camelopardalis thornicrofti) in Zambia

Reproductive suppression is common among mammals residing in cooperative social systems and is characterized by the cessation of ovulation in subordinate females until their social environment releases them from a temporary freeze on ovulating (e.g., dwarf mongoose, Helogale parvula (Creel, Creel, Wildt, & Monfort, 1992); African wild dogs, Lycaon pictus (Creel, Creel, Mills, & Monfort, 1997); wolves, Canus lupus (Packard, Seal, Mech, & Plotka, 1985); Damaraland mole rats, Cryptomys damarensis (Bennett, 1994); common marmosets, Callthrix jacchus (Barrett, Abbott, & George,
