Hemotropic mono- and coinfections in Colombian ruminants: descriptive occurrence and host-related factors associated with coinfection in cattle

Carolina Ríos Úsuga · Lina María Rendón Ramos · Ingrid Lorena Jaramillo Delgado · Nathalia M. Correa-Valencia

Hemotropic pathogens such as Anaplasma, Babesia, Mycoplasma, and Trypanosoma are endemic to cattle and can cause coinfections, complicating disease dynamics and control. However, the host-related factors influencing these infections under tropical conditions remain poorly understood. This study aimed to investigate the...

L-threonine 3-dehydrogenase overexpression enhances tolerance to oxidative, genotoxic, and drug-induced stress in Trypanosoma cruzi

Ana María Mejía-Jaramillo · Paola García-Huertas · Carlos Renato Machado · Omar Triana-Chávez

Trypanosoma cruzi is a digenetic parasite that undergoes various transformations to complete its life cycle. Changes between hosts and vectors involve exposure to stressful environments, for which it has developed different strategies to cope with such stress. L-threonine 3-dehydrogenase (TDH) is a key enzyme in trypan...
