The study aimed to determine the prevalence of blood parasites in horses and identify risk factors and molecular detection of piroplasm species (Theileria equi and Babesia caballi) of horses in Myanmar. Blood samples (n = 302) were collected from five regions of Myanmar. Blood smears were screened for presence of piroplasms. Samples positive for piroplasms were subjected to molecular identification using primers specific to the small subunit ribosomal RNA (SSU rRNA) of piroplasms. The overall prevalence of blood parasites (piroplasms, Trypanosoma spp., and microfilaria of Setaria equina) was 30.8% (93/302). The prevalence of piroplasms, Trypanosoma spp., and microfilaria of S. equina, were 22.5% (68/302), 8.3% (25/302), and 2.3% (7/302), respectively. Samples from Yangon (35.0%) and Mandalay (35.0%) showed the highest prevalence, followed by Northern Shan State, Ayeyarwady, and Nay Pyi Taw (33.9%, 25.0% and 24.6%, respectively). The hypothesized factors (age, sex, and breed) showed no significant association (p > 0.05) with the overall occurrence of blood parasites. Although no significant association (p > 0.05) was found between blood parameters (WBCs, RBCs, Hb, and HCT) and the presence of blood parasites, the negative group had a larger WBC count than the positive group. Molecular characterization of piroplasm of two obtained sequences confirmed Theileria equi. This is the first report on microscopic and molecular detection of T. equi in horses in Myanmar, and the findings provide baseline information for blood parasites in horses.

Leishmania donovani is an intracellular protozoan parasite that has successfully evolved to manipulate host macrophages. The exact mechanism by which Leishmania spp evades macrophage function is not fully understood. Recently, several studies have shown that pathogens target host-microRNA to alter cellular pathways for their persistence.

Background: The increasing recognition of zoonotic malaria, particularly from Plasmodium species infecting non-human primates (NHP), poses significant diagnostic challenges. Performance of human malaria Rapid Diagnostic Tests (RDTs) has not been evaluated in simian malaria.
Methods: A total of 131 blood samples from NHP hosts with confirmed malaria were analyzed using 14 different commercially available RDTs, detecting the antigens P.

Malaria, a protozoan parasitic disease caused by Plasmodium species, poses significant health risks in endemic regions and contributes to substantial morbidity and mortality. The intricate lifecycle of the parasite, coupled with the emergence of drug-resistant strains, has severely impacted the effectiveness of current anti-malarial treatments. In response, the present study attempts to demonstrate the blood-stage anti-plasmodial action of 30 triazole derivatives designed based on molecular hybridisation technique, and physicochemical properties.

Coinfection of humans with Hepatitis B Virus (HBV) and non-viral pathogens may worsen the outcome of HBV infection on the liver. This study determined the prevalence of Heliobacter pylori, Salmonella typhi, Plasmodium falciparum, and Toxoplasma gondii among Hepatitis B Virus (HBV)-infected persons in the Greater Accra Region (GAR) of Ghana and examined how such co-infections might affect the levels of selected liver function markers (LFM). The design was cross-sectional, involving 120 HBsAg-positive HBV-infected persons.

Introduction: Parasitic nematodes are prevalent in fish populations. The parasites are pathogenic but depress host responses, which limit clearance of the pathogens from the invasion sites. We hypothesized that one of several control strategies, which could augment protection, is immunization of the fish host with parasite antigens prior to live pathogen exposure.
