The aims of the present study were to determine the prevalence of hemoplasmas in cats and dogs from the Barcelona area of Spain with the use of species-specific quantitative polymerase chain reaction (qPCR) assays and to evaluate any associations between hemoplasma infection, clinical presentation, and vector-borne infections. Blood samples from cats (191) and dogs (182) were included and were classified as healthy (149) or unhealthy (224). Ethylenediamine tetra-acetic acid blood samples underwent DNA extraction and qPCR analysis. Mycoplasma haemofelis, 'Candidatus Mycoplasma haemominutum', and 'Candidatus Mycoplasma turicensis' were detected in cats, whereas Mycoplasma haemocanis and 'Candidatus Mycoplasma haematoparvum' were detected in dogs, with prevalences of 3.7%, 9.9%, 0.5%, 14.3%, and 0.6%, respectively. In cats, no association between hemoplasma infection and health status, age, breed, presence of anemia, Feline leukemia virus status, and other vector-borne infections was found, but outdoor access (P = 0.009), male sex (P = 0.01), and Feline immunodeficiency virus status (P < 0.001) were significantly associated with hemoplasma infection. In dogs, sex, age, health status, presence of anemia, and breed were not significantly associated with hemoplasma infection, but a significant association was found between hemoplasma infection and vector-borne infections (P < 0.001). The present report documents the occurrence of feline 'Candidatus M. turicensis' and canine 'Candidatus M. haematoparvum' infections in Spain.

Unlabelled: Bacterial pathogens remain poorly characterized in bats, especially in North America. We describe novel (and in some cases panmictic) hemoplasmas (10.1% positivity) and bartonellae (25.

Hemotropic mycoplasmas are unculturable bacteria that infect the surface of red blood cells of several mammalian species including cattle. The importance of hemoplasmas in cattle remains unclear and limited information is available about biological routes of transmission. The objective of this cross-sectional study was to determine the prevalence of transplacental transmission of hemoplasmas and to determine if colostrum of infected cows contained DNA from hemoplasma organisms.

Armadillos and anteaters exhibit a wide range of interactions with various pathogens and ectoparasites, which, along with their physiological and ecological characteristics, contribute to their potential as hosts for a broad variety of pathogens with zoonotic potential. However, there has been limited research into the occurrence and diversity of vector-borne agents in this group of mammals. The present study aimed to investigate the occurrence and molecular identity of Ehrlichia spp.

Hemoplasmas (HM) infect a wide range of mammals and may cause hemolytic anemia. We detected HM in a melon-headed whale (Peponocephala electra) stranded in Veracruz, Mexico. Sequencing and phylogenetic analysis of 16S and 23S rDNA indicated the presence of a HM that was previously detected in cetaceans from South America.

Arthropod vectors play a crucial role in the transmission of hemotropic mycoplasmas, small bacteria that infect red blood cells in a wide range of animals and humans globally, leading to intravascular infections. Traditional Giemsa-stained thin blood smears, used for diagnosing hemotropic mycoplasmas through microscopic examination, have low sensitivity and are effective only when bacteremia levels are high. This study aimed to employ molecular methods to detect and genetically characterize hemotropic mycoplasmas in goats as well as investigate the potential role of fleas as vectors.
