A total of 147 cats from the Sydney area of Australia that had blood samples submitted to veterinary laboratories were tested using a real-time polymerase chain reaction (PCR) assay able to detect and distinguish the two feline haemoplasma species. This sample number included two cats diagnosed with feline haemoplasma infection by routine blood smear examination. Statistical analysis was performed to evaluate associations between haemoplasma infection, age, sex, breed, haematocrit (HCT) values and anaemia status. One hundred and six cats (72.1%) were negative. Thirty-four cats (23.1%) were positive for 'Candidatus M. haemominutum', six cats (4.1%) were positive for M. haemofelis and one cat (0.7%) was positive for both species. Older, male, non-pedigree cats, with lower HCT values were more likely to be infected with 'Candidatus M. haemominutum'. Significant inverse correlation was found between the amount of M. haemofelis DNA present in the blood and the HCT value. This report documents the existence of, and prevalence of, both haemoplasma species in a sample of cats in Australia and is the first to use quantitative real-time PCR in a prevalence study for haemoplasma infection.

Article Synopsis
- Cats in Türkiye are significant hosts for various vector-borne haemopathogens, but there is limited research on these pathogens among companion animals.
- A study analyzed 250 blood samples from cats, revealing that 16% were infected with haemopathogens, with low prevalence rates for piroplasm, Mycoplasma, and Bartonella species, while no Anaplasma/Ehrlichia or Rickettsia were found.
- The findings contribute important data regarding zoonotic risks associated with these infections and highlight specific strains of pathogens present in Turkish feline populations.

Bacterial vector-borne pathogens (BVBPs) negatively impact canine health worldwide, with several also being zoonotic, posing an additional disease risk to humans. To date, BVBPs have been reported in humans and various sylvatic and domestic animal hosts across multiple Mongolian aimags (provinces); however, there has been no published data on these pathogens within Mongolia's canine populations. Collection of such data is important given Mongolia's size, diverse number of climatic regions, and large population of dogs, most of which closely share their environment with humans and livestock.

Dog-infecting haemotropic mycoplasmas (haemoplasmas), such as Mycoplasma haemocanis and Candidatus Mycoplasma haematoparvum are common blood-borne pathogens of canines that can potentially inflict a substantial burden of disease, particularly in immunosuppressed individuals. Nonetheless, the transmission of these pathogens remains debated as more evidence emerges that they may not be transmitted by vectors, but instead use alternative methods such as aggressive interactions and vertical transmission. Here, we treated forty dogs with two different topically-acting ectoparasiticide products able to prevent vector-borne pathogen infections during an 8-month community trial in Cambodia.
