Antibiotic Resistance Profile of sp. Isolates from Commercial Laying Hen Farms in Central-Western Brazil.

Microbial resistance to antibiotics poses a significant threat to both human and animal health, necessitating international efforts to mitigate this issue. This study aimed to assess the resistance profiles of sp. isolates and identify the presence of 1, 1, and TEM resistance genes within antigenically characterized isolates, including Agona, Livingstone, Cerro, Schwarzengrund, enterica subsp.

Survey of Campylobacter in foods implicated in foodborne diseases in Southern Brazil.

Campylobacter is not routinely tested in foodborne disease investigations in Brazil. Here, we studied the occurrence of Campylobacter among other food-related bacteria commonly found in foodborne disease outbreaks reported in Rio Grande do Sul State, Southern Brazil. Seventy-two food samples were analyzed by using culture-based detection methods during the 18-month investigation of 36 foodborne disease outbreaks.

Design of primer pairs for species-specific diagnosis of Leishmania (Leishmania) infantum chagasi using PCR.

The objective of this study was to design and evaluate new primers for species-specific detection of L. infantum chagasi using PCR. Two combinations of primer pairs were established with the aim of obtaining specific amplification products from the L.

Phylogenetic characterization of Babesia canis vogeli in dogs in the state of Goiás, Brazil.

The genus Babesia comprises protozoa that cause diseases known as babesiosis. Dogs are commonly affected by Babesia canis or Babesia gibsoni. Babesia canis is divided into the subspecies Babesia canis canis, Babesia canis vogeli and Babesia canis rossi.

[Canine visceral leishmaniasis in dog from Caldas Novas, Goiás].

The objective of the present work was to describe a visceral case of leishmaniasis in a dog from Caldas Novas, GO, region until then considered as a disease free area. The animal, attended in the Veterinarian Hospital of the Federal University of Goiás, presented loss of weight, alopecic area of irregular format at the nasal back, onicogrifosis, atrophy of the heads muscles and failure of the right popliteus lymphonode. For the laboratorial diagnosis, samples were collected by biopsy from the complete skin of the auricular region, by punsion from the popliteus lymphonode for preparation of Giemsa stained blades and 5 mL of the blood were also collected for serum diagnosis.

Assessment of primers designed for the subspecies-specific discrimination among Babesia canis canis, Babesia canis vogeli and Babesia canis rossi by PCR assay.

Canine babesiosis is an infectious disease caused by either Babesia gibsoni or Babesia canis protozoans. The latter is also classified under three different phylogenetic groups, referred to as subspecies B. canis canis, B.
