Coronaviruses (CoVs) are a large group of enveloped viruses with a single-strand RNA genome, which continuously circulate in mammals and birds and pose a threat to livestock, companion animals, and humans. CoVs harboured by avian species are…

To date, 13 amphipod species [Dikerogammarus haemobaphes(Eichwald, 1841); D. istanbulensis Özbek & Özkan, 2011; D. gruberi Mateus & Mateus, 1990; Echinogammarus ischnusStebbing, 1899; Pontogammarus robustoides (Sars, 1894); P. maeoticus(Sowinsky,…

Avastrovirus infection is associated with enteric disease, nephritis, and hepatitis in birds. In this study, we present a protocol for the complete sequencing of the ORF2 gene of avian nephritis virus (ANV), chicken astrovirus (CAstV), and turkey…

In South Africa, almost all existing businesses are regarded as Small Medium and Micro Enterprises (SMMEs). Through legislation, the South African government has identified SMMEs as the best enablers to help with the achievement of certain core…

In our continued search for natural compounds with activity against Trypanosoma brucei, causative agent of human African trypanosomiasis (HAT, “sleeping sickness”), we have investigated extracts from the leaves and bark of the West African Holarrhena…

The article is devoted to studies the performance of oral fluid of children of 6-7 years, which often suffer from acute respiratory viral infections. Examination of 111 children with frequent acute respiratory viral infection and 89 healthy children…

Accurate species identification from ancient DNA samples is a difficult task that would shed light on the evolutionary history of pathogenic microorganisms. The field of palaeomicrobiology has undoubtedly benefited from the advent of untargeted…

For qualitative and semi-quantitative detection of genetically modified crops we selected the detection of the frequently used promoter 35S CaMV. To optimise the method we used two commercially available genotypes of maize from the company Monsanto…

Performance testing of two brands of surgical helmets indicated that their efficiency at in vivo filtration of sub–micrometer-sized particles is inadequate for their use as respirators. These helmets are not marketed for respiratory protection and…
