Free-roaming dogs and cats represent potential reservoirs for zoonotic vector-borne pathogens shedding to the human population. Given the health impact of these pathogens, we searched free-roaming dogs and cats included in an animal population control program from Luanda, Angola, for and hemotropic mycoplasma infection. We report the detection of (2/66; 3%), Mycoplasma haemominutum (5/66; 7.
View Article and Find Full Text PDFA total of 100 domestic cats from Luanda (Angola) were tested for the presence of antibodies against Bartonella henselae and spotted fever group of Rickettsia (SFGR) using indirect immunofluorescence assay (IFA). Molecular screening targeting the riboflavin synthase (ribC) gene for Bartonella and outer membrane protein B (ompB) gene for Rickettsia, using conventional PCR and sequencing was also performed in cat´s blood samples. Sixty-six percent of the cats from Luanda had IgG antibodies against Bartonella species but none of them had antibodies against SFGR.

The presence of bacterial (Anaplasma and Ehrlichia) and protozoal (Babesia and Hepatozoon) agents was investigated in blood samples from 102 domestic cats from Luanda, Angola, by polymerase chain reaction and DNA sequencing.
Results: Three cats (2.
Article Synopsis
- * Once in the Americas, these ancestors split into two main genetic branches around 13,000 years ago: one branch spread throughout North and South America, while the other remained mainly in North America.
- * Contrary to the Paleoamerican Model, ancient populations like the Pericúes and Fuego-Patagonians are not closely related to modern Australo-Melanesians, and there has been some genetic exchange with present-day East Asians.
