Abstract:
Hemoplasmas (hemotropic mycoplasmas) are small pleomorphic bacteria that parasitize the surface of red blood cells of several mammalian species including cattle, goats, and humans, causing infectious anemia. However, studies on hemoplasmas have been neglected and to date, there are no studies on bovine and caprine hemoplasmas in Uganda or the entire East African region. In this study, a polymerase chain reaction (PCR) assay targeting the 16S rRNA gene was used to investigate the presence of hemoplasma in 409 samples (cattle = 208; goats = 201) collected from Kasese district, western Uganda. Results showed that 32.2% (67/208) of cattle samples and 43.8% (88/201) of goat samples were positive for hemoplasmas. Sequencing analysis identified Candidatus Mycoplasma haemobos and Mycoplasma wenyonii in cattle, while Candidatus Mycoplasma erythrocervae and Mycoplasma ovis were identified in goats. Statistical analysis showed that goats were at a higher risk of infection with hemoplasmas compared with cattle. To the best of our knowledge, this is the first molecular evidence of hemoplasmas in bovine and caprine animals in Uganda and the entire east African region.
Insights
This study detected hemotropic mycoplasmas (hemoplasmas) in cattle and goats in Uganda using PCR. Goats showed a higher infection rate, with specific species identified in both animals.
Area of Science:
- Veterinary Microbiology
- Molecular Diagnostics
- Parasitology
Background:
- Hemoplasmas are red blood cell parasites causing anemia in mammals.
- Previous research on bovine and caprine hemoplasmas in East Africa is scarce.
- This study addresses the knowledge gap in Uganda and the broader East African region.
Purpose of the Study:
- To molecularly investigate the prevalence of hemoplasmas in cattle and goats in western Uganda.
- To identify specific hemoplasma species infecting these livestock populations.
- To compare infection risks between cattle and goats.
Main Methods:
- A polymerase chain reaction (PCR) assay targeting the 16S rRNA gene was employed.
- Samples were collected from 409 animals (208 cattle, 201 goats) in the Kasese district.
- Sequencing was used for species identification.
Main Results:
- Hemoplasmas were detected in 32.2% of cattle and 43.8% of goats.
- Identified species in cattle: *Candidatus* Mycoplasma haemobos and *Mycoplasma wenyonii*.
- Identified species in goats: *Candidatus* Mycoplasma erythrocervae and *Mycoplasma ovis*.
- Goats exhibited a statistically higher risk of hemoplasma infection compared to cattle.
Conclusions:
- This study provides the first molecular evidence of hemoplasmas in cattle and goats in Uganda and East Africa.
- The findings highlight a significant prevalence and differential risk of infection in these livestock.
- Further research is warranted to understand the clinical impact and transmission dynamics of hemoplasmas in the region.
