High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.

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.

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

Biological Reviews, Volume 101, Issue 6, Page 2634-2655, December 2026.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...

Molecular Detection of Spotted Fever Group Rickettsia in Ticks Collected From Wildlife Carcasses at a Bushmeat Market in Ghana

Public Health Challenges, Volume 5, Issue 4, December 2026.
At the Atwemonom bushmeat market in Kumasi, 211 ticks were collected from 46 wildlife carcasses and grouped into 94 pools. Rickettsia DNA occurred in 10 pools (10.64%), comprising Rickettsia africae and Rickettsia massiliae; Coxiella burnetii was undetected.

Expression of Human CYP2D6 in Artificial Cells Based on Polymer‐Lipid Hybrid Vesicles

ChemBioChem, Volume 27, Issue 21, 12 November 2026.
Expression of eGFP and human cytochrome P450 2D6 (CYP2D6) within the lumen of giant polymer‐lipid hybrid vesicles using a Leishmania tarentolae‐based cell‐free protein expression system is illustrated. Both proteins were expressed in the vesicle lumen, and low‐polymer‐content hybrid vesicles were the most suitable scaffolds for CYP2D6 expression with ...
