Article Synopsis
  • - Researchers investigated Anaplasma and Ehrlichia infections in beef cattle in Maputo, Mozambique, due to a lack of data on their economic impact and epidemiology.
  • - They collected blood samples from 200 healthy cattle and performed DNA testing, finding a high prevalence of Anaplasma marginale (71%) and Ehrlichia ruminantium (9.5%), with some co-infections.
  • - The study revealed significant genetic diversity in the Anaplasma species and identified five new genotypes of Ehrlichia ruminantium in the cattle from this region.

Small ruminants, particularly goats and sheep, are key livestock species in Mozambique, and their production is mainly undertaken by families. However, small ruminants are often plagued by diseases that can cause considerable economic damage. In this context, traditional remedies, including various plant species, have been widely used to manage these diseases.

Donkeys (Equus asinus) are rustic animals, but in Africa's poorest regions, they can present multiple health problems, including tick infestation. The study's objective was to determine the species composition of ticks that infest donkeys in Maputo Province (Mozambique). Ticks were collected in five conveniently selected southern districts of Maputo Province (Moamba, Matutuíne, Marracuene, Boane, and Matola) and were identified to species level using a stereoscopic microscope with the aid of dichotomous identification keys.

Rotavirus A (RVA) is an important pathogen causing gastroenteritis in many species, including humans and pigs. The objective of this study was to determine the prevalence of RVA in pigs from smallholdings and commercial farms in southern Mozambique and characterize the complete genomes of selected strains. RVA was detected at a rate of 11.

Background: In Mozambique, bacterial and parasitic diseases contribute to a high burden of mortality and morbidity. These infectious diseases are treated with antibiotics, antihelmintic or antiparasitic drugs. However, misuse of these has been affecting the potential to treat ailments.

There is no effective natural alternative control for gastrointestinal nematodes (GIN) of small ruminants, with Haemonchus contortus being the most economically important GIN. Despite frequent reports of multidrug-resistant GIN, there is no new commercial anthelmintic to substitute failing ones. Although trematocidal activity of artemisinin analogs has been reported in sheep, neither artemisinin nor its plant source (Artemisia annua) has been evaluated for anthelmintic activity in ruminants.
