Molecular Diagnosis of the Main Hemoparasites of Dairy Cows in the State of Ceará.

Background/objectives: Trypanosomiasis and bovine babesiosis correspond to important diseases that cause great economic losses, but there are still no studies evaluating their occurrence in herds of dairy cattle in Ceará. The aim of this study was to perform molecular diagnosis of the main hemoparasites of dairy cows in the microregion of the central hinterland of Ceará.

Methods: For the molecular diagnosis of parasites, genomic material was extracted and polymerase chain reaction directed to the cdCatL-like gene for and SS rRNA of and was performed.

Molecular and serological detection of Leishmania infantum (Trypanosomatida: Trypanosomatidae) in domestic dogs in Manaus city, Amazonas, Brazil.

Leishmaniasis are zoonosis widely spread in Brazil, caused by the protozoan of the genus Leishmania, which includes several species. The disease manifests itself in the visceral or tegumentary form, and the main reservoir is the dogs. Manaus is the largest city in the Brazilian Amazon region, and despite the importance of the municipality, practically nothing is known about leishmaniosis in humans and animals.

Contribution of ultrasound examination in diagnosing platynosomiasis and correlation with macro and microscopic findings in callitrichids kept under human care.

Background: Platynosomiasis in non-human primates kept under human care causes chronic disease of the bile ducts and liver, which initially presents with nonspecific signs and can culminate in the death of the animal. Diagnosing this disease is a challenge, and an ultrasound examination can be an excellent tool when it is suspected.

Methods: This study describes the ultrasound findings from 57 marmosets with suspected infection by Platynosomum sp.

Molecular Detection of Tick-Borne Pathogens in Dogs from Indigenous Communities, Amazon, Brazil.

There are few reports of tick-borne pathogens infecting dogs living in indigenous communities of Brazil. Herein, we aimed to molecularly detect vector-borne pathogens in dogs from two indigenous communities in the Brazilian Amazon. We surveyed 327 dogs raised in Amazon region at 2 distinct indigenous ethnicities for the molecular detection of tick-borne pathogens (114 from Tapirapé and 213 from Karajá indigenous ethnicity).

Morphological anomalies in hard ticks (Acari: Ixodidae) from Brazil.

Tick abnormalities have been unusual in nature, and they can be divided into local and general. In the present study, external morphological anomalies were described in 31 individual adult ticks of 15 different species of Ixodidae, which were collected on wild hosts (20 ticks), domestic hosts (7 ticks), and in the environment (4 ticks) in 11 states of Brazil from 1998 to 2022. Among the 31 tick specimens, 14 (45%) were categorized as local anomalies, and 17 (55%) as general anomalies.
