Basson, Lizanne; Hassim, Ayesha; Dekker, At; Gilbert, Allison; Beyer, Wolfgang; Rossouw, Jennifer; Van Heerden, Henriette (AOSIS Open Journals, 2018-06-26)Anthrax, caused by Bacillus anthracis, is endemic in the Kruger National Park (KNP). The epidemiology of B. anthracis is dependent on various factors including vectors. The aims of this study were to examine non-biting ...

Onyeka, L.O. (Libby); Adesiyun, Abiodun Adewale; Keddy, Karen H.; Hassim, Ayesha; Smith, Anthony M.; Thompson, P.N. (Peter N.) (Elsevier, 2022-08)In South Africa, there is a shortage of epidemiologic data on Shiga toxin-producing Escherichia coli (STEC) in the beef production chain. This study was conducted to characterise STEC isolates originating from three studies ...

Lekota, Kgaugelo Edward; Hassim, Ayesha; Van Heerden, Henriette (Elsevier, 2020-02)This report presents genomic data on sequence reads and draft genomes of Bacillus anthracis isolates from anthrax outbreaks in animals in an endemic region of South Africa as well as genotyping of the strains using ...

Ledwaba, Maphuti Betty; Gomo, Calvin; Lekota, Kgaugelo Edward; Le Flèche, Philippe; Hassim, Ayesha; Vergnaud, Gilles; Van Heerden, Henriette (Public Library of Science, 2019-05-20)Brucella abortus and B. melitensis have been reported in several studies in animals in Zimbabwe but the extent of the disease remains poorly known. Thus, characterizing the circulating strains is a critical first step in ...

Lekota, Kgaugelo Edward; Hassim, Ayesha; Madoroba, Evelyn; Hefer, Charles A.; Van Heerden, Henriette (Elsevier, 2020-06)Bacillus anthracis, the aetiological agent of anthrax, is regarded as a highly monomorphic pathogen that presents a low genetic diversity using standard molecular techniques. Whole genome sequencing and single nucleotide ...

Lekota, Kgaugelo Edward; Hassim, Ayesha; Mafofo, Joseph; Rees, Jasper; Muchadeyi, Farai Catherine; Van Heerden, Henriette; Madoroba, Evelyn (Open Learning on Enteric Pathogens, 2016)INTRODUCTION : Bacillus anthracis is the causative agent of anthrax, a disease endemic in regions of Northern Cape Province and Kruger National Park of South Africa. Accurate identification of virulent B. anthracis is ...

Mazwi, Koketso Desiree; Kolo, Francis Babaman; Jaja, Ishmael Festus; Byaruhanga, Charles; Hassim, Ayesha; Van Heerden, Henriette (MDPI, 2024-01)In livestock, brucellosis is mainly an asymptomatic disease except when abortion occurs; therefore, two serological tests are used for diagnosis as no single test is suitable. Abattoir samples enable a combination of ...

Forde, Taya L.; Dennis, Tristan P.W.; Aminu, O. Rhoda; Harvey, William T.; Hassim, Ayesha; Kiwelu, Ireen; Medvecky, Matej; Mshanga, Deogratius; Van Heerden, Henriette; Vogel, Adeline; Zadoks, Ruth N.; Mmbaga, Blandina T.; Lembo, Tiziana; Biek, Roman (Microbiology Society, 2022-02)Genomic sequencing has revolutionized our understanding of bacterial disease epidemiology, but remains underutilized for zoonotic pathogens in remote endemic settings. Anthrax, caused by the spore-forming bacterium ...

Lekota, Kgaugelo Edward; Hassim, Ayesha; Rogers, P.; Dekker, E.H.; Last, R.; De Klerk-Lorist, Lin-Mari; Van Heerden, Henriette (BioMed Central, 2018-05-02)OBJECTIVES : Anthrax is a disease with an age old history in Africa caused by the Gram-positive endospore forming soil bacterium Bacillus anthracis. Epizootics of wild ungulates occur annually in the enzootic region of ...
-
Hassim, Ayesha; Dekker, Edgar H.; Byaruhanga, Charles; Reardon, Tommy; Van Heerden, Henriette (AOSIS OpenJournals, 2017-09-28)Anthrax is a zoonotic disease caused by the gram-positive, endospore-forming and soil-borne bacterium Bacillus anthracis. When in spore form, the organism can survive in dormancy in the environment for decades. It is a ...

Mazwi, Koketso Desiree; Kolo, Francis Babaman; Jaja, Ishmael Festus; Bokaba, Refilwe Philadelphia; Ngoshe, Yusuf Bitrus; Hassim, Ayesha; Neves, L.C.B.G.D. (Luís); Van Heerden, Henriette (Hindawi, 2023-12)Zoonotic infections were investigated in a cross-sectional study on asymptomatic livestock slaughtered in abattoirs in the Eastern Cape. Antibodies against Brucella spp., Coxiella burnetii, Toxoplasma gondii, and the ...
