Item Die geskiedenis van die Berlynse Sendinggenootskap in Transvaal, 1860-1900Van der Merwe, D.W. (University of Pretoria, 1984)English: The object of this dissertation was to investigate the history of the Berlin Missionary Society in the Transvaal from 1860-1900. However, in order to provide a complete picture of the activities of the Berlin Missionary Society in the Transvaal it was also necessary to give attention to the development, administration and organisation of the Society in Germany, as well as in the Transvaal. As the success of the Society was to a great extent dependent on the attitude of the government in the Transvaal, its relationship with the authorities was also scrutinised. Likewise a section on the contacts between the Berlin Missionary Society and other Missionary Societies in the Transvaal is also included. The dissertation is based on extensive research of both primary and secondary sources. The material was systematically gathered and thematically divided into ten chapters. Apart from the sources consulted in the State Archives in Pretoria, valuable information was obtained in the archives of the Berlin Missionary Society in East Berlin. Locally extensive collections of documents at the mission stations Bothsabelo and Edendale were consulted. The Berlin Missionary Society originally wanted to undertake mission work among the Swazi, but as the Revs. Merensky and Gri.itzner were refused permission by the Swazis to establish a mission station, the Society, with the approval of the South African Republic, established a station at Gerlachshoop among the Bakopa tribe in July 1860. In 1861 the work of the Berlin Missionary Society in the Transvaal received a significant impetus when it extended its activities to include the Bapedi. Between 1861 and 1864 three mission stations, the most important being Kchalatlolu, were established among the Bapedi. Although the mission progressed favourably, all three mission stations had to be abandoned in 1866 when the Bapedi chief Sekhukhune adopted an antagonistic attitude towards mission work. New avenues in which to continue their mission however eventually arose so that despite initial reverses the Berlin Missionary Society decided to retain the Transvaal as a permanent mission field. Mission stations were established under the Bantu chiefs Matlala, Mankoapane, Malaboch, Kgolokoe, Tshivase, Madzivhandila, Makoarela, Modjadji, Jan Kekana, and Andries Maubane. In addition, mission stations were established at various towns in the Transvaal, such as Heidelberg, Johannesburg, Potchefstroom, Pretoria, Pietersburg, Lydenburg, Middelburg and Ermelo. During the 40 years considered in this dissertation the Berlin Missionary Society achieved considerable success in its pastoral work. In 1860 there was one mission station with only two missionaries and one baptised Bantu member, as against the 30 mission stations, 105 outposts and 36 full-time missionaries in 1900. At the latter date there were also over 20 000 baptised Bantu members. In this dissertation the following conclusions were arrived at: The Berlin missionaries considered their primary task to be the christianisation and education of the Bantu to become civilised and useful citizens of the state in which they lived. Consequently the Berlin missionaries enjoyed to a great degree the respect and esteem of the South African Republic and its inhabitants. In almost direct contrast to the London Missionary Society, the Berlin missionaries, with the exception of the Rev. Merensky, never became involved in the political affairs of the South African Republic. Although Merensky's activities during the annexation of the Transvaal in 1877 antagonised the Boers, there is nevertheless unambiguous evidence that the Committee of the Berlin Missionary Society in Germany condemned his actions. Furthermore, it was ascertained that the Berlin missionaries sincerely strove to community. Their attempts in this connection were, however, never characterised by a meddlesome philanthropism, but rather by a just and worthy attitude towards all population groups. Indirectly the Berlin missionaries assisted the South African Republic in establishing its authority over recalcitrant Bantu tribes. Because the Berlin missionaries enjoyed the confidence of most of the Bantu chiefs they were used as informants and intermediaries between the government and the respective Bantu chiefs. Their mission work enabled the Berlin missionaries to acquire an intimate knowledge of the Bantu, and they have made a valuable contribution to our knowledge of early Bantu history. Similarly, by means of their knowledge of the Bantu languages the missionaries enriched the Bantu's own cultural and national life. In conclusion, it can be unequivocally stated that the Berlin missionaries played a positive and significant role in the history of the Transvaal, and although they were seldom in the forefront of affairs, their contribution is undoubtedly worthy of attention. promote good race relations in the Transvaal. In this respect they stressed co-operation between white and non-white, and saw such co-operation as the basis for a progressiveItem Quantification of Angora goat beta chain haemoglobin variants using the Sebia Capillarys 2 Flex-Piercing systemParsons, Sven David Charles; Vermeulen, A.; Hobson, M.; Hooijberg, Emma Henriette (Medpharm Publications, 2025-02)This study aimed to evaluate the utility of the Sebia Capillarys 2 Flex-Piercing (C2FP) system for the quantification of the major caprine beta chain haemoglobin (Hb) variants, i.e. foetal Hb, neonatal Hb, and adult Hb. Blood samples were collected from six Angora kids at one, 11, and 20 weeks after birth, and analysed using the C2FP instrument and Capillarys Hemoglobin(E) kit. Electropherograms displayed three major peaks which showed consistent changes in relative magnitude as kids aged. At one week old, a peak at position ~75 was identified as foetal Hb, while in older animals, peaks at ~150 and ~170 were identified as neonatal Hb and adult Hb, respectively. In conclusion, this study has confirmed the utility of the Sebia C2FP system for the simple, rapid, and standardised quantification of the major beta chain Hb variants of Angora goats.Item First report of a Sporidesmin toxicity (facial eczema) outbreak in a South African dairy herdDavis, Anthony John; Jordaan, Daniel Du Plessis Scheepers; Myburgh, Jan G. (Medpharm Publications, 2025-03)Sporidesmin, a toxin released by a saprophytic fungus, Pseudopithomyces chartarum, causes hepatogenous photosensitivity in sheep and cattle, commonly known as Facial Eczema. A recent outbreak in the Eastern Cape Province of South Africa caused significant direct and indirect economic losses to a farmer in the area and highlighted the potential negative consequences of this mycotoxicosis to the dairy industry in this province. The milking herd consisted of 400 cross-bred Jersey/Friesian/Montbilliard cattle. The farmer identified 56 cows showing teat sensitivity/irritability during milking, hypersensitive skin, excessive licking and/or obvious skin lesions on non-pigmented skin areas. Three were culled due to the severity of their skin lesions. Grazing consisted of mixed kikuyu/perennial rye grass pasture under pivot irrigation, alternated with dryland kikuyu/Italian rye and sorghum. Typical clinical signs of severe secondary photosensitivity (skin inflammation and hypersensitivity to touch), very high serum concentrations of Gamma-Glutamyl Transferase (GGT 2143-5177 IU/L) and detection of large numbers of spores on grazed planted pastures supported the clinical diagnosis. Supplementation of zinc oxide (ZnO) powder at 12g per 500 kg cow dosed individually over the concentrates fed in the dairy, effectively reduced the incidence of new cases within two to three weeks. Weight loss, a decrease in milk volume and solids, and increased somatic cell counts were observed during this outbreak. One of these parameters, milk volume loss, was quantified by comparing the financial records of the four years preceding the outbreak to the production figures during the outbreak. The farmer lost approximately R1.5 million in milk volume during this outbreak (November 2020 - April 2021). Long term consequences were also apparent: the culling rate within the clinically affected group of 53 cows was more than 50% higher than the rest of the herd over the following two years. This case study highlights the urgent need to investigate the prevalence and potential economic impact of Sporidesmin Toxicity on the South African pasture-based dairy industry.Item Systematic review and meta-analysis of fertility outcome following in vivo insemination with sex-sorted semen in sheepNel, J.G.; Thompson, P.N. (Peter N.); Holm, Dietmar Erik (Medpharm Publications, 2025-02)BACKGROUND : Sex-sorted semen (SS) offers economic benefits to sheep producers, but lower fertility outcome (FO), defined as probability of pregnancy, pregnancy rate or lambing rate, than that following conventional semen (CS) artificial insemination (AI) may limit its use OBJECTIVES : To systematically review the literature, and analyse factors associated with FO following AI in sheep using SS vs CS. METHODS : Available literature was searched using the PRISMA guidelines, resulting in 11 studies with 14 experiments that were reviewed. From these, information from 70 study cohorts representing 13 experiments was used to conduct a meta-analysis which confirmed that FOs for SS and CS AI were 37% (95% CI = 31-43%) and 52% (95% CI = 45-59%), respectively (p < 0.01). RESULTS : FO improved over time, with FO following SS and CS AI improving at the same rate over the period investigated (19972022). In a subgroup analysis, five factors were identified that potentially decrease the FO after SS AI disproportionately. These were sperm dose < 4 χ106 spermatozoa, semen preservation (fresh vs frozen-thawed), oestrus synchronisation using an intravaginal sponge (vs a controlled internal drug release device), presence of gonadotropin-releasing hormone in the synchronisation protocol, and absence of biostimulation using a teaser ram. In a random-effects model analysis, an interaction between sperm dose and SS vs CS, and semen preservation were independent predictors of FO after adjusting for the effect of timing of insemination. CONCLUSION : FO following insemination with SS is 15% lower than that of CS, which can be narrowed by increasing the semen dose for SS inseminations and improving the synchronisation of ovulation with the timing of insemination.Item Person-centred HIV care and prevention for youth in rural South Africa : preliminary implementation findings from Thetha Nami ngithethe nawe stepped-wedge trial of peer-navigator mobilization into mobile sexual health servicesBusang, Jacob; Ngoma, Nqobile; Zuma, Thembelihle; Herbst, Carina; Okesola, Nonhlanhla; Chimbindi, Natsayi; Dreyer, Jaco; Smit, Theresa; Bird, Kristien; Mtolo, Lucky; Behuhuma, Osee; Hanekom, Willem; Herbst, Kobus; Lebina, Limakatso; Seeley, Janet; Copas, Andrew; Baisley, Kathy; Shahmanesh, Maryam (Wiley, 2025-10)INTRODUCTION : Despite the efficacy of antiretroviral therapy (ART)-based prevention, population-level impact remains limited because those at high risk of HIV acquisition are not reached by conventional services. We investigated whether youth-centred and tailored HIV prevention, delivered by community-based peer navigators alongside sexual and reproductive health (SRH) services, can mobilize demand for HIV pre-exposure prophylaxis (PrEP) and ART among adolescents and young adults (AYA) in KwaZulu-Natal, South Africa. METHODS : Thetha Nami ngithethe nawe is a cluster-randomized stepped-wedge trial (SWT) in 40 clusters within a rural health and demographic surveillance site. Clusters were randomized to receive the intervention in period 1 (early) or period 2 (delayed). Trained area-based peer navigators conducted needs assessments with youth aged 15-30 years to tailor health promotion, psychosocial support and referrals into nurse-led mobile SRH clinics that also provided HIV testing, and status-neutral ART and oral PrEP. Standard of care was PrEP delivered through primary health clinics. We report SRH service uptake from the 20 intervention clusters during the first period of the SWT (NCT05405582). RESULTS : Between June 2022 and September 2023, peer-navigators reached 9742 (74.9%) of the 13,000 youth in the target population, 46.8% males. Among 9576 individuals with needs assessment, peer-navigators identified 141 (1.5%) with social needs, and 4138 (43.5%) had medium to high health needs. These individuals were referred to mobile clinics, with 2269 (54.8%) attending, including 959 (42.3%) males. HIV testing uptake was high (92.7%; 2103/2269), with 10.1% (212/2103) testing positive for HIV, 62 (29.2%) of whom started ART for the first time. The prevalence of HIV was higher among females compared to males (15.1% vs. 3.3%; p < 0.001). Among clinic attendees, 96.8% were screened for PrEP eligibility, with 38.5% deemed eligible and offered PrEP. Of the 1433 (63.2%) individuals tested for sexually transmitted infections (STIs), 418 (29.2%) tested positive, with females having higher STI prevalence (37.2% vs. 17.9%; p < 0.001). Of these, 385 (92.1%) received STI treatment. Among 1310 females, 769 (58.7%) reported not using any contraception at their initial visit, and 275/769 (35.8%) started contraception during the trial. CONCLUSIONS : Community-based and person-centred approaches delivered through trained peer-navigators can link AYA with SRH and HIV prevention/care needs with mobile SRH services.
