(University of Pretoria, 2017)In summary, this study presents a novel genetic test based on msp1aS to discriminate strains of A. centrale and shows that the vaccine strain is found widely distributed across South Africa and in animals that do not have ...
-
(University of Pretoria, 2011)The aim of this study was to investigate three key epidemiological aspects of Theileria parva infections in cattle and African buffalo (Syncerus caffer) in South Africa. The first of these was the possible behavioural ...
-
Aspects of the immune response in ruminants to four protective Ehrlichia ruminantium gene products (University of Pretoria, 2008-08-11)In the search for a better vaccine against Ehrlichia ruminantium infection in ruminants, four E. ruminantium open reading frames (ORFs) derived from the Welgevonden isolate were tested using either DNA vaccination or DNA ...
-
(University of Pretoria, 2019)The Mnisi community, a rural area, is nestled at the cusp of a human/livestock/wildlife interface in Bushbuckridge Municipality, Mpumalanga Province, South Africa. In this area, undifferentiated non-malarial acute febrile ...
-
(University of Pretoria, 2015)The Mnisi community is in the north-eastern corner of the Bushbuckridge Municipal Area, Mpumalanga Province, South Africa. This community is located at the livestock/wildlife interface sharing borders with several game ...
-
(University of Pretoria, 2012-09-14)In South Africa, the diagnosis of Theileria parva in cattle and buffalo has been complicated by the presence of mildly pathogenic and non-pathogenic Theileria spp. This can lead to inaccurate diagnostic results and confuse ...
-
(University of Pretoria, 2011-01-06)A shotgun genome sequencing project was undertaken in the expectation that access to the entire protein coding potential of E. Ruminantium (Welgevonden) will facilitate the identification of vaccine candidate genes against ...
-
(University of Pretoria, 2016)This study was conducted to understand the occurrence, diversity and epidemiology of tickborne diseases (TBDs) in a transhumant pastoral area of Karamoja Region, Uganda. We used participatory epidemiology (PE), involving ...
-
(University of Pretoria, 2010-05-24)The aim of this study was to improve the official diagnostic test package in South Africa for detection of Theileria parva infections in cattle and Cape buffalo (Syncerus caffer) and to investigate the presence of cattle-type ...
-
(University of Pretoria, 2023)Leptospirosis is an important bacterial infection of both animals and humans, largely neglected worldwide. Leptospirosis occurs worldwide and is maintained in numerous animal hosts. The aim of this study was to investigate ...
-
(University of Pretoria, 2009-04-15)Babesia bovis outbreaks were reported in cattle alleged to be immunised with the commercially available live-blood vaccine in the Swartberg region of KwaZulu-Natal, South Africa and an investigation into the nature of ...
-
(University of Pretoria, 2018)Bovine anaplasmosis, a tick-borne disease caused by the rickettsia Anaplasma marginale, has a significant economic impact for cattle farmers in South Africa. We have estimated the economic cost due to mortality arising ...
-
(University of Pretoria, 2009)In an attempt to develop quantitative real-time PCR (qPCR) assays for the detection of equine piroplasms, sequence heterogeneity in the V4 hypervariable region of the 18S ribosomal RNA (rRNA) gene sequences within both ...
-
(University of Pretoria, 2017)Anaplasmosis is a tick-borne disease that can result in serious loss of production and even loss of livestock. It is caused by the most globally prevalent vector-borne pathogen of livestock, Anaplasma marginale, with endemic ...
-
(University of Pretoria, 2012)Theileriosis, babesiosis, heartwater and anaplasmosis are considered to be amongst the most important tick-borne diseases of livestock in sub-Saharan Africa‟s tropical and subtropical regions resulting in extensive economic ...
-
(University of Pretoria, 2009-09-03)Blood was collected from 71 tsessebe antelope and ticks from 12 of these animals, in the Vaalbos National Park. The samples were collected when the animals were relocated to a new park as a result of the deproclamation of ...
-
(University of Pretoria, 2013-07-12)Ehrlichia ruminantium is a tick-borne pathogen transmitted by ticks in the genus Amblyomma. This bacterial pathogen causes heartwater, a fatal disease affecting domestic and wild ruminants in sub-Saharan Africa. The ...
-
Occurrence of tick-borne haemoparasites in cattle in the Mungwi district, Northern Province, Zambia (University of Pretoria, 2012)The most important tick-borne diseases (TBDs) occurring in Zambia that affect domestic animals, particularly cattle and small ruminants, are theileriosis (East Coast fever and Corridor disease), anaplasmosis (gall sickness), ...
-
(University of Pretoria, 2019)Anaplasmosis, babesiosis, and heartwater are the three most important tick-borne diseases of cattle in South Africa and result in a large number of mortalities. Endemic stability contributes to disease control, but little ...
-
(University of Pretoria, 2015)The African buffalo (Syncerus caffer) is host for many pathogens known to cause economically important diseases and is often considered an important reservoir for livestock diseases. Theileriosis, heartwater, babesiosis ...
