| the incidence and nature of prohibited animal tissues in boerewors ("country-style" sausage). | sixty boerewors ("country-style" sausage) samples bought from butchers in pretoria were examined microscopically. it was found that 97% of these samples contained animal tissues that are not permitted in boerewors under the regulations of the foodstuffs, cosmetics and disinfectants act (act no. 54 of 1972). these regulations confine permitted tissues to fat and the musculature of cattle, sheep and pigs. details of the tissues revealed in the survey are provided, and the implications of their pre ... | 1977 | 562415 |
| parasites of domestic and wild animals in south africa. vii. helminths in pigs slaughtered at the pretoria municipal abattoir. | a total of 52 pigs slaughtered at the pretoria municipal abattoir over a period of 1 year was examined for parastitic helminths. twenty-six of these pigs were marketed by farmers and 26 by speculators. of the pigs marketed by farmers 73,1% were found to be infested:--30,8% with ascaris suum, 65,4% with ascarops strongylina, 3,8% with metastrongylus apri, 26,9% with oesophagostomum spp., 15,4% with trichostrongylus colubriformis and 15,4% with trichuris suis. all the pigs marketed by speculators ... | 1978 | 568230 |
| group b and c porcine rotaviruses identified for the first time in south africa. | the incidence of rotavirus at a pig farm in gauteng was determined by polyacrylamide gel electrophoresis (page). faecal specimens were collected from 172 litters over a 6-month period. rotavirus was detected in 37.8% of piglets exhibiting signs of scouring. when these page patterns were examined, 84.6% group a, 4.6% group b and 10.8% group c rotaviruses were observed. a few specimens subsequently collected from other farms in the gauteng. north-west and northern provinces also contained group b ... | 1996 | 9120852 |
| culicoides (diptera:ceratopogonidae) associated with livestock in the onderstepoort area, gauteng, south africa as determined by light-trap collections. | in 54 light-trap collections made at 28 sites in the onderstepoort area a total of 178,941 culicoides midges of 35 species was collected in march 1988; the survey was repeated at 26 sites in september and yielded 19,518 culicoides of 24 species. the number of culicoides species collected totalled 38. c,imicola was the most abundant species at 27 of the 28 sites sampled, and accounted for 88% and 67% of all midges collected in the two months respectively. this study not only confirms that c. imic ... | 1996 | 9173363 |
| phage types of salmonella enterica serovar enteritidis isolated in south africa from 1991-1995. | a total of 615 strains of salmonella enterica serovar enteritidis (se), received from 1991-1995 at the onderstepoort veterinary institute (ovi), were phage typed. most se isolates (54,7%) originated from poultry followed by humans (28,5 %) and poultry eggs (9,6 %). phage type 34 was the most prevalent (40,5 %) of all isolates, followed by phage type 4 (33,8 %). other phage types identified were 1, lb, 4a, 7, 7a, 9a, 14, 24, 24var and 35 (in total 2,4% of isolates). most isolates of se were recei ... | 2000 | 11028749 |
| variance in rotavirus infection rates in different urban population groups in south africa. | rotavirus infection in black infants contrasts markedly with that of white infants in being much less common and showing no seasonal variation. in this multicentre study in johannesburg, the aetiology of winter infantile gastroenteritis in black, coloured, and white infants was investigated. stools were examined by electron microscopy and also by enzyme-immunoassay to detect subparticular antigen which may be missed by electron microscopy in patients presenting late in the course of the illness. ... | 1982 | 6296311 |
| parasites of south african wildlife. x. helminths of red duikers, cephalophus natalensis, in natal. | the helminths of the following red duikers, cephalophus natalensis, were examined: 24 from 3 game reserves in natal and 1 that had originated from charters creek, natal, shortly before it died in the national zoological gardens, pretoria. the 21 animals from charters creek harboured 16 nematode species, a nematode genus, 2 cestode species and paramphistomes. the 2 red duiker from fanies island harboured 4 nematode species, 3 nematode genera and 1 cestode species, while the single red duiker from ... | 1991 | 1923384 |
| HIV-related conspiracy beliefs and its relationships with HIV testing and unprotected sex among men who have sex with men in Tshwane (Pretoria), South Africa. | Abstract The objective of this study was to determine extent of HIV conspiracy belief endorsement among men who have sex with men (MSM) in Pretoria, and assess whether endorsement of HIV conspiracy beliefs are associated with inconsistent condom use and never testing for HIV. A cross-sectional survey using respondent-driven sampling was conducted between February and August 2009. A high proportion of respondents endorsed HIV conspiracy beliefs. MSM commonly endorsed beliefs related to AIDS inf ... | 2011 | 22084826 |
| antimicrobial susceptibility in thermophilic campylobacter species isolated from pigs and chickens in south africa. | campylobacter jejuni is one of the leading causes of sporadic food-borne bacterial disease in humans. in intensive poultry and pig rearing systems the use of oral antibiotics is essential to maintain health. consequently, there is a high risk for the thermophilic campylobacter jejuni and c. coli resident in the intestinal tract of food animals to develop resistance to commonly used antibiotics. contamination of meat or eggs with pathogenic strains of resistant campylobacter could, therefore, res ... | 2010 | 21526738 |
| prevalence of the dog nematode spirocerca lupi in populations of its intermediate dung beetle host in the tshwane (pretoria) metropole, south africa. | spirocerca lupi (spirurida: spirocercidae) is a cosmopolitan parasite, principally of domestic dogs and dung beetles are its main intermediate hosts. in south africa there has recently been growing concern over the upsurge of reported cases of clinical spirocercosis in dogs, while little is known or understood about the dynamics of the host-parasite associations between dung beetles and this nematode. we determined and compared the prevalence of infection in dung beetles between rural, urban and ... | 2008 | 19294987 |
