Detection of tick-borne rickettsial pathogens in naturally infected dogs and dog-associated ticks in Medellin, Colombia

Abstract Tick-borne rickettsial pathogens (TBRP) are important causes of infections in both dogs and humans. Dogs play an important role as a biological host for several tick species and can serve as sentinels for rickettsial infections. Our aim was to determine the presence of TBRP in dogs and in dog-as...

Molecular detection of Cercopithifilaria bainae and other tick-borne pathogens in Rhipicephalus sanguineus s.l. isolated from dogs in Midwest Brazil

Abstract The aim of the present study was to detect Cercopithifilaria bainae and other tick-borne pathogens and to perform molecular characterization of the tick Rhipicephalus sanguineus s.l. collected from dogs. Ticks (n = 432, including 8 larvae, 59 nymphs, and 365 adults) were sampled from domiciled d...

Molecular detection of vector-borne agents in cats in Southern Brazil

Abstract This study used serological and molecular methods to investigate the occurrence of vector-borne pathogens (VBP) with zoonotic potential in cats neutered at the University Veterinary Hospital in Canoinhas, Santa Catarina. The combined PCR and serological results revealed that 17 (56.6%) cats were...

Molecular detection of Bartonella, Ehrlichia and Mycoplasma in feral dogs of El Pedregal de San Angel Ecological Reserve in Mexico City

Abstract Free-ranging and feral dogs represent a group of unattended companion animals. They impact wild animal populations by predating native species, displacing predators and introducing exotic pathogens. The aim of this work was to describe the molecular occurrence of Rickettsia, Ehrlichia, Anaplasma...

Hemoparasites in ticks of wild birds of Serra dos Órgãos National Park, state of Rio de Janeiro, Brazil

Abstract The aim of this study is to detect the presence of tick-borne agents of genera Rickettsia, Borrelia, Babesia, Ehrlichia and Anaplasma in ticks collected from native wild birds in the state of Rio de Janeiro. Birds were captured and observed carefully to find the ectoparasites. DNA detection of h...

Detection of a putative novel genotype of Ehrlichia sp. from opossums (Didelphis aurita) from Brazil

Abstract Erlichiosis affects humans and animals worldwide. Its distribution and prevalence depends on the presence of tick vectors and hosts in one geographic area. The aim of the present study was to investigate the occurrence of Ehrlichia spp. and Anaplasma spp. in opossums (Didelphis sp.) from the St...

Detection of Anaplasma sp. phylogenetically related to A. phagocytophilum in a free-living bird in Brazil

Abstract Wild animals play an important role in carrying vectors that may potentially transmit pathogens. Several reports highlighted the participation of wild animals on the Anaplasma phagocytophilum cycle, including as hosts of the agent. The aim of this study was to report the molecular detection of a...

Molecular survey of Anaplasma platys and Ehrlichia canis in dogs from Campo Grande, Mato Grosso do Sul, Brazil

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT This study investigated the frequency of infection by Anaplasma platys and Ehrlichia canis in dogs submitted to animal health centers in Campo Grande, state of Mato Grosso do Sul, Brazil. E. canis and A. platys showed infection frequencies of 55.75% and 16.96%, respectively. The identity of the ...

Molecular detection of Anaplasma species in dogs in Colombia

Abstract Anaplasma platys and A. phagocytophilum are tick-borne pathogens that parasitize platelets and neutrophils, respectively, of humans and animals. The former is the etiological agent of canine cyclic thrombocytopenia, while the latter is that of canine granulocytic anaplasmosis. This work involved...
