Molecular Detection of Kinetoplastid Species in Ticks and Fleas Associated with Dogs and Humans in Mexico.

The Trypanosomatidae family encompasses around 24 genera of unicellular protozoans, many of which are transmitted by various hematophagous arthropods, particularly members of the Orders Diptera and Hemiptera. Fleas and ticks-an understudied group of ectoparasites-have been shown to be hosts of a wide and crescent variety of trypanosomatid species. Further, fleas and ticks of companion animals have been particularly neglected in trypanosomatid surveillance despite the proximity to human populations and the anthropophagous habits of many of these arthropods, which can potentially act as vectors of zoonotic trypanosomatids.

New records of Rhipicephalus linnaei infected by Rickettsia massiliae from Central Mexico.

Background: On the American continent, Rhipicephalus sanguineus s.l. comprises two species: Rhipicephalus linnaei and R.

New records, and molecular detection of vector-borne pathogens in Felicola subrostratus from eastern Mexico.

The study of lice associated with domestic cats is a neglected area of veterinary parasitology. In particular, the presence of the cat louse Felicola subrostratus, a small Ischnoceran species found in the fur of the domestic cat, is rarely recognized. In America, this species has been reported across six countries.

Rediscovering an old friend: the case of Ixodes dampfi in a protected natural reserve in central Mexico.

The tick Ixodes dampfi Cooley 1943, a member of the Pholeoixodes subgenus, was first described from gophers (Geomys sp.) collected in the state of Mexico. However, information on the origin and parasite-host association of I.

Molecular detection of Rickettsia sp. cf. Rickettsia monacensis in Ixodes sp. cf. Ixodes affinis collected from white-tailed deer in Campeche, Mexico.

Deer encompass a group of large-sized vertebrates that serve as hosts for a wide variety of ectoparasites, mainly ticks. In Mexico, ticks have relevance as vectors of pathogenic microorganisms, and 20 species of hard ticks are associated with four species of deer, although only a single study has been conducted to detect bacterial agents associated with ticks from deer in the country. In February, 2019 three white-tailed deers (Odocoileus virginianus) were hunted from the locality of Chiná from the municipality of Campeche, Mexico.

Molecular detection of Theileria equi in horses from Veracruz, Mexico.

Equine piroplasmosis is a tropical parasitic disease caused by several intraerythrocytic members of the genera Babesia and Theileria. These pathogens are transmitted by multiple tick species and are considered as important exotic microorganisms in several countries. Equine piroplasmosis causes significant economic losses due to abortions, decreased activity and even death of equines, making surveillance of these infectious disease essential.

Molecular Confirmation of Rickettsia parkeri in Amblyomma ovale Ticks, Veracruz, Mexico.

We found Rickettsia parkeri in Amblyomma ovale ticks collected in Veracruz, Mexico, in 2018. We sequenced gene segments of gltA, htrA, sca0, and sca5; phylogenetic reconstruction revealed near-complete identity with R. parkeri strain Atlantic Rainforest.
