Equine piroplasmosis is a parasitic illness caused by various protozoa of the Babesia and Theileria genera, which parasitize within red blood cells. The transmission of these pathogens occurs through certain genus of ticks, including Amblyomma, Haemaphysalis, Hyalomma, and Rhipicephalus. In recent times, an increase in the identification of new Theileria species and genotypes has been observed.

- * Out of 930 fecal samples analyzed, 39.7% of calves were found to be infected, with Eimeria canadensis being the most common species identified.

Article Synopsis
- Ehrlichia canis is a significant health concern in dogs, often causing high morbidity and mortality, and can be difficult to diagnose due to asymptomatic cases and cross-reactivity in serological tests.
- A study examined 59 euthanized dogs with ticks but no clinical symptoms, finding that while 52.55% tested negative for E. canis in blood samples, 61.30% were positive in tissue biopsies.
- Results indicated that E. canis DNA was present in various organs despite blood tests being negative, highlighting the limitations of blood PCR and the need for more comprehensive testing in tissues.
