Article Abstract
Reptiles are hosts for various tick species and tick-associated organisms, many of which are zoonotic. However, little is known about the presence and diversity of tick-borne bacteria infecting reptiles and their ticks in South Africa. ticks ( = 253) collected from reptiles were screened for the presence of , , and species by amplification, sequencing and phylogenetic analysis of the 16S rRNA, 23S rRNA, , , and genes, respectively. This study recorded the presence of reptile associated species and -like endosymbiont in South Africa for the first time. Furthermore, a spotted fever group species was observed in 7 and 14 from tortoises of genera and . -like endosymbiont was observed from 2 collected from the Mozambique spitting cobra, . and spp., were not detected from the current samples. Although the direct evidence that reptiles can act as reservoir hosts remains to be determined, observations from this study provide indications that reptilian ticks may play a role in the transmission of pathogenic bacteria to homothermic animals. Furthermore, the absence of spp., and . does not mean that these pathogens should be completely neglected.
Introduction: Hearing loss and Deafness/deafness affects as much as 5% of the world's population and has a considerable health and economic burden. We explored the relationship with hearing and hearing aids as well as other assistive technology for health in general with a cohort of UK adults who have conductive hearing loss. We anticipated that insights could lead to greater understanding for the delivery of assistive technology (AT) for conductive hearing loss and the participant's lived experience related to technology and society.
In this study, composite biscuits were produced by combining wheat flour (WF) with different proportions of malted pearl millet (MPM) flour (8%, 16%, 24%, and 32%) and orange peel (OP) flour (2%, 4%, 6%, and 8%), using 100% WF as a control. The investigation covered the functional properties, viscosity, and thermal properties of the flours, along with the proximate composition, antioxidant, physical properties, color attributes, and microbial quality of the composite biscuits. As MPM and OP flour (OPF) contents increased, water absorption capacity, dispersibility, and foaming power increased, while the viscosities of both hot and cold pastes decreased.
The spotted ragged-tooth shark, , is widely distributed in subtropical continental coastal seas. In South Africa, it is commonly found along the entire south and east coasts, including the iSimangaliso Wetland Park (IWP) in the far north, which is the largest Marine Protected Area on the South African coast. Pregnant females occur there for much of the year, with the largest aggregations in summer.
Background: Rift Valley Fever (RVF) is a mosquito-borne zoonotic disease that poses a serious threat to both humans and livestock across various regions, particularly in Africa, the Arabian Peninsula, and parts of the Indian Ocean Islands. This study seeks to analyze the spatial and temporal distribution and trends of RVF outbreaks within the East African Community (EAC) countries, offering insights into the patterns and progression of these outbreaks in the region.
Methods: We conducted a retrospective analysis of the Program for Monitoring Emerging Diseases (ProMed), a digital, event-based disease surveillance system, to identify reports of outbreak events in Uganda, Kenya, Rwanda, Burundi, Tanzania, and South Sudan from 2010 to 2024.
