Trypanosoma sp. infection in Boa constrictor snakes: morphological, hematological, clinical biochemistry, molecular, and phylogenetic characteristics.

There are few reports of Trypanosoma in snakes, as well as little information about its pathogenicity in these animals. Thus, the present study aimed to characterize Trypanosoma found in Boa constrictor snakes, to verify the influence of the parasitism on hematological and clinical biochemistry parameters, and to perform a phylogenetic study of the isolates. Blood samples from sixty-one boas were analyzed for the presence of trypanosomatids and by hematological and clinical biochemistry assays.

Detection of Hemopathogens in : Microscopic, Molecular, Hematological, and Clinical Biochemistry Aspects.

The growing contact between men and wild animals, caused by the increase in the population in urban centers and the destruction of the habitat of these animals, has been leading to a greater circulation of pathogens between humans and wildlife. , a tortoise found throughout South America, is one of the animals most rescued from animal trafficking and illegal breeding. Considering this situation, this study aimed to verify the occurrence of hemoparasites in .

First description of Candida haemulonii infecting a snake Boa constrictor: Molecular, pathological and antifungal sensitivity characteristics.

Candida haemulonii is an emergent infectious pathogen that affects human presenting comorbidities and/or immunodepression. Little is known about other possible hosts. For the first time, this fungus was found causing a cutaneous infection in a snake, Boa constrictor, characterized by scale opacity and several ulcerative lesions.

AFFINITY OF BRAZILIAN WILD MAMMAL IMMUNOGLOBULINS TO BACTERIAL PROTEINS A AND G.

Staphylococcal A and streptococcal G proteins are widely used in immunoassays when specific immunological reagents are unavailable, such as for wild animals. The affinity of bacterial proteins A and G to the immunoglobulins of seven Brazilian mammals were tested, including black-tufted marmoset (, = 5), golden-bellied capuchin (, = 13), woolly mouse opossum (, = 6), long-nosed armadillo (, = 5), collared anteater (, = 5), ocelot (, = 6), and vampire bat (, = 5). Blood samples were collected from animals that were rescued in peri-urban rainforest fragments.

Hematology and Clinical Biochemistry Profiles in Antillean Manatee Trichechus manatus manatus from Different Types of Captivity and Free Living in Northeast Brazil.

The Antillean manatee Trichechus manatus manatus can be found along the northern and northeastern coasts of Brazil. Previous studies on the clinical biochemistry of these animals were conducted in North America and the Caribbean, whereas little is known regarding these parameters in South American manatee populations. Accordingly, the objective of the present study was to examine the hematology and clinical biochemistry of Antillean manatees of different sexes and from different environments in northeast Brazil.

Rabbit as an Animal Model for Ocular Surface Disease, Tear Osmolarity, Electrolyte, and Tear Ferning Profiles.

Significance: The tear film promotes ocular surface health and protection through its various constituents' functions. The application of methods for ocular surface examination is essential in the research of diseases that affect the tear film. Rabbits have been used as a model to study some human ocular diseases and to test ophthalmic products.

Comparison of Electrolyte Composition and Crystallization Patterns in Bird and Reptile Tears.

To compare tear electrolytes and tear crystallization patterns in birds and reptiles, tears were sampled by Schirmer tear test from 10 animals each of , and , and 5 of . The aliquots were pooled to assess concentrations of total protein, chloride, phosphorus, iron, sodium, potassium, calcium, and urea. For the tear ferning test, samples of each species were observed under a polarized light microscope at room temperature and humidity.

Biogenic Silver Nanoparticles as a Post-surgical Treatment for Infection in Small Ruminants.

Caseous lymphadenitis (CL) is an infectious and zoonotic disease characterized by the development of granulomas in the lymph nodes and internal organs of small ruminants. The etiological agent of this disease is , a Gram-positive and facultative intracellular bacterium. The conventional treatment for CL consists of drainage and chemical cauterization of the lesions using a 10% iodine solution.

Affinity of Staphylococcal a and Streptococcal G Proteins to West Indian Manatee ( Trichechus manatus manatus) Immunoglobulins.

The West Indian manatee ( Trichechus manatus manatus), a subspecies that inhabits coastal areas of Central and South America, has been listed as a vulnerable species because of the rapid decline in its population. Commercially available immunologic reagents specific for sirenians are lacking, limiting the development of sensitive immunodiagnostic assays. We observed the affinity of the microbial proteins A and G to T.
