Trematodes of free range reared guinea fowls (Numida meleagris Linnaeus, 1758) in the state of Rio de Janeiro, Brazil: Morphology and pathology
An investigation on the digenetic trematodes parasitizing free range reared guinea fowls was conducted in the state of Rio de Janeiro, Brazil, based on clinical examination, necropsies andExpand
Feline sporotrichosis: epidemiological and clinical aspects.
TLDR
Severe pyogranulomatous inflammatory infiltrate, high fungal load, and extension of lesions to mucosa, cartilage, and bone in the nose of cats are indicative of an agent of high virulence in this endemic region. Expand
Prevalence and pathology of the nematode Heterakis gallinarum, the trematode Paratanaisia bragai, and the protozoan Histomonas meleagridis in the turkey, Meleagris gallopavo.
TLDR
The prevalence of infection and associated pathology induced by two helminth and one protozoan species infecting Brazilian turkeys are reported and a severe inflammatory process in the liver and cecum is revealed. Expand
Occurrence of anti-Toxoplasma gondii antibodies in cattle and pigs slaughtered, State of Rio de Janeiro.
TLDR
Despite the low prevalence rates found for cattle and pigs, these indicated environmental contamination in the municipalities investigated, biosafety failures at the technified pig farm evaluated and the possibility of human and animal infection through eating raw or undercooked meat from these animals. Expand
Pathology and first occurrence of the kidney trematode Paratanaisia bragai (Santos, 1934) Freitas, 1959 (Digenea: Eucotylidae) in Phasianus colchicus L., 1758, from Brazil.
The kidney trematode Paratanaisia bragai is reported for the first time parasitizing the ring-necked pheasant (Phasianus colchicus L., 1758) and the pathological alterations associated to theExpand
Sensitivity and specificity of serological tests, histopathology and immunohistochemistry for detection of Toxoplasma gondii infection in domestic chickens.
TLDR
The MAT was the most effective method for the diagnosis of T. gondii infection in chickens, followed by ELISA, due to their specificity. Expand
T-Cell Populations and Cytokine Expression Are Impaired in Thymus and Spleen of Protein Malnourished BALB/c Mice Infected with Leishmania infantum
TLDR
Protein malnutrition results in a drastic dysregulation of T cells and cytokine expression in the thymus and spleen of L. infantum-infected BALB/c mice, which may lead to defective regulation of theThymocyte population and an impaired splenic immune response, accelerating the events of a normal course of infection. Expand
Capillariid nematodes in Brazilian turkeys, Meleagris gallopavo (Galliformes, Phasianidae): pathology induced by Baruscapillaria obsignata and Eucoleus annulatus (Trichinelloidea, Capillariidae).
TLDR
The pathology induced in turkeys by two capillariid nematodes, Baruscapillaria obsignata and Eucoleus annulatus, is described together with data on prevalences, mean infection and range of worm burdens. Expand
Tissue alterations in the pirarucu, Arapaima gigas, infected by Goezia spinulosa (Nematoda).
TLDR
This is the first report of tissue lesion occurrences in this host, in the presence of G. spinulosa, and it confirms the high pathogenicity of this parasite species. Expand
First report of natural infection of a bush dog (Speothos venaticus) with Leishmania (Leishmania) chagasi in Brazil.
TLDR
The first known case of natural infection of a bush dog with Leishmania (Leishmania) chagasi in Brazil is reported, calling attention to the parasitological and etiological control of certain zoonoses, such as leishmaniasis, in wild animals kept in captivity, especially when animals are exchanged between zoos in Brazil.
