Molecular detection and phylogenetic analysis of tick-borne pathogens in cattle from southern Malawi.

Introduction: Tick-borne diseases (TBDs) pose a major hindrance to livestock production in countries with limited resources. Effective prevention and management of TBDs require a thorough understanding of disease vectors and pathogens. However, there is limited information on studies of bovine tick-borne pathogens (TBPs) using molecular methods in Malawi.

Bovine Piroplasma Populations in the Philippines Characterized Using Targeted Amplicon Deep Sequencing.

Molecular assays and capillary electrophoresis sequencing have been used to identify parasites in livestock. The low sample capacity, which increases labor and processing time, is one drawback. Targeted amplicon sequencing (Ampliseq) uses the fast and large sample capacity platform to identify parasites in the target host, overcoming this limitation.

To date, there have been several studies on the prevalence of tick-borne pathogens (TBPs) in cattle, but very few studies have documented TBPs in goats in Uganda. In this study, polymerase chain reaction assays and sequence analysis of different molecular markers were used to assess the presence and genetic characteristics of TBPs in 201 goats from Kasese district in western Uganda.

First Molecular Detection and Characterization of Hemotropic Species in Cattle and Goats from Uganda.

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.

Molecular detection and characterization of tick-borne haemoparasites among cattle on Zanzibar Island, Tanzania.

Results revealed detection of A.

Confers Macrophage-Based Cross-Protective Immunity Against Murine Malaria.

Malaria and babesiosis, the two primary intraerythrocytic protozoan diseases of humans, have been reported in multiple cases of co-infection in endemic regions. As the geographic range and incidence of arthropod-borne infectious diseases is being affected by climate change, co-infection cases with and are likely to increase. The two parasites have been used in experimental settings, where prior infection with has been shown to protect against fatal malarial infections in mice and primates.

In the present study, Amblyomma variegatum ticks were used to find out more about bovine tick-borne pathogens. DNA extracts from 910 adult ticks collected off cattle in North East Benin were examined for Babesia bigemina, B.

Genetic characterization of tick-borne pathogens in ticks infesting cattle and sheep from three South African provinces.

Ticks are involved in the transmission of many public health and veterinary important pathogens. Although tick-borne pathogens are widely distributed in South Africa, information on tick-pathogen relationship needs to be updated particularly using modern molecular techniques. This study used PCR and sequencing to confirm the identity of the tick species collected from cattle and sheep from KwaZulu-Natal, Free State and Eastern Cape.
