Leishmania major chromosomes are replicated from a single high-efficiency locus supplemented by thousands of lower efficiency initiation events

Cell Reports
Summary: DNA replication initiates at genome sites termed origins. Previous origin mapping approaches in the populations of the protozoan parasite Leishmania major were discordant, suggesting either a single origin per chromosome or 200-fold more origins.

Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, Volume 40, Issue 1, Page 91-100, March 2026.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.

Development and Characterization of Microsatellite Genetic Markers for Hyalomma rufipes, a Tick Vector of Crimean‐Congo Hemorrhagic Fever Virus

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

The Effect of Synthetic Cow Urine on Microorganisms and Their Potential Phosphorus Mining Activity in Rhizosphere and Bulk Soil

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 69-80, February 2026.
ABSTRACT Background and aims Soil microbes adapt to varying nutrient inputs by modifying their utilization strategies, with root exudates and animal urine serving as key carbon (C) and nutrient sources in grasslands. Nonetheless, the specific mechanisms by which cow urine and root exudates influence microbial community and resource utilization remain ...
