A dermatofitose é uma infecção micótica superficial dos tecidos queratinizados como pelos, unhas e o estrato córneo da epiderme. Nos cães gatos, esta enfermidade comumente causada por fungos dermatófitos gêneros Microsporum, Nannizzia Trichophyton que podem acometer quaisquer pacientes, sendo os filhotes, animais idosos imunocomprometidos mais propensos. Embora seja doença altamente contagiosa, sua mortalidade baixa em alguns casos, pode haver remissão espontânea. afeta cerca de 4-15%...
Neospora caninum is a protozoan which can cause abortions in caprines. However, information regarding the humoral immune response and occurrence of reproductive disorders scarce. This first study kinetics antibodies studied pregnant goats naturally infected by N. caninum, as well their respective conceptuses. The subclasses IgG (IgG1 IgG2) were also evaluated goats. Reproductive problems related to neosporosis (abortion stillbirth) occurred 15.38% There was statistically significant...
Congenital Neospora caninum infection was diagnosed in two Saanen goat kids from distinct herds with a history of abortion and weak newborn the Southern region State Minas Gerais, Brazil. The first kid at birth, had difficulty to rise unable nurse. Gross lesions porencephaly hydrocephalus ex vacuo were seen. Multifocal necrosis, gliosis non-supurative encephalitis observed brain. Several parasitic cysts thick wall that reacted strongly only polyclonal antiserum seen cerebral cortex, brain...
The aim of this study was to evaluate the effects oat beta-glucan supplementation on metabolic, physiological, immunological and nutritional variables in adult dogs. Fourteen dogs were fed a control diet or supplemented with 1% during 71 days. Serum concentrations glucose, total cholesterol lipoprotein fractions, as well plasma peptide YY ghrelin, determined. In addition, coefficient tract apparent macronutrient digestibility (CTTAD), food intake fecal output, score, pH evaluated. For...
The activity of carvacrol was evaluated in R. microplus female ticks by estimating the mean lethal concentration (LC50) and acaricidal efficacy. Ticks were subjected to Adult Immersion Test (AIT) calculate LC50. From this value, AIT performed again at concentrations 20%, 40%, 60%, 80% 100% Two control groups established: one treated with distilled water solvent (ethanol 50%). following parameters evaluated: weight before oviposition, egg mass weight, pre-oviposition incubation period,...
Ten-month-old calves Bos taurus were immunized with three doses of SBm7462 saponin as an adjuvant at 30-day intervals and evaluated for IgG isotypes, phenotype circulating lymphocytes changes in the lymph nodes (LN). stimulated production predominantly IgG1-isotype antibodies. The exhibited activation seventh day after first immunization, areas paracortical interfollicular hyperplasia early formation germinal centers (GC). Fifteen days GC compartmentalization cellular populations, a light...
Neospora caninum is an apicomplexan protozoan that considered one of the main agents responsible for abortion in ruminants. The lesions found central nervous system (CNS) aborted fetuses show multifocal necrosis, gliosis, and perivascular cuffs mononuclear cells, but inflammatory glial cells have not been immunophenotypically characterized. CNS infected adult animals rarely described. Therefore, this study, we characterized lesions, immunophenotypes expression MHC-II PCNA goats with N....
A public health issue, Diabetes mellitus, affects millions of people around the globe. Ingestion foods with a low glycemic index - fiber-rich meals-such as beta-glucans, is increasing an important alternative for diabetes control. These compounds act reducing parameters such blood glucose, cholesterol and triglycerides, by decreasing absorption glucose lipids enterocytes eventually promote weight loss. Beta-glucans are also described immunomodulatory agents stimulating phagocytosis...
Este estudo avaliou a participação de Neospora caninum em casos abortos bovinos provenientes propriedades rurais da região sul Minas Gerais por meio análises histopatológicas, imuno-histoquímicas (IHQ) e pela reação Cadeia Polimerase (PCR). O material utilizado foi obtido um retrospectivo aborto recebidos pelo Setor Patologia Veterinária Universidade Federal Lavras fetos necropsiados durante os anos 2011 2013. De 60 estudados, 30 (50%) tinham lesões microscópicas. Destes, 19 (63%)...
ABSTRACT The present study aimed to evaluate the occurrence of polymorphisms in Diacylglycerol acyltransferase (DGTA-1 and 2), Fatty acid synthase (FASN), Stearoyl-CoA desaturase (SCD) genes Thioesterase domain FASN (TE-FASN) gene that may be related lipid profile. In experiment, a total 84 sheep from different genetic groups were used. For evaluation polymorphism genes, PCR-Single Strand Conformation Polymorphism (SSCP) technique subsequent sequencing DGAT-2 gene, four genotypes identified...
Trypanosomiasis is caused by a pathogenic protozoan of the genus Trypanosoma, being Trypanosoma vivax most important agent for cattle. The aim present study was to demonstrate expansion T. infection in different mesoregions Minas Gerais, Brazil, and describe clinicopathological findings trypanosomiasis diagnosis based on visualization parasite blood smears DNA detection live cows tissues necropsied animals polymerase chain reaction (PCR). Thirty suspected herds were tested, which 11 positive...
Cows experience a significant negative protein balance during the first 30 d of lactation. Given functional effects AA on health, especially in challenging periods such as calving, higher levels and specific diet may act to improve health feed intake. The response dairy cows 3 supplementation strategies transition period through 45 milk was evaluated. final data set had 39 Holstein blocked based parity (primiparous vs. multiparous) expected calving randomly assigned within each block one...
SUMMARY This study was conducted to determine the seroprevalence of anti- Neospora caninum antibodies and investigate risk factors related in dogs from urban rural areas with distinct economic activities (milk coffee production) Minas Gerais state, Brazil. For this purpose, blood samples 703 were collected questionnaires addressing epidemiological aspects completed by dog-owners. The sera analysed for N. indirect fluorescent antibody tests (IFAT ⩾ 1:50). Association between seropositivity...
ABSTRACT: Leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus, resulting in various clinical forms, including highly lethal visceral form. This study aimed to identify spp. sandflies and dogs small Brazilian town. DPP® Visceral Canine (CVL) was used for screening, ELISA conventional PCR were confirmatory testing, while captured using CDC light traps targeting ITS1. The Hill series diversity profile species sampled area R software. identified prevalence 4.02% dogs,...
Background: Bluetongue (BT) is a viral disease transmitted by hematophagous vectors of the genus Culicoides. In Brazil, identifcation antibodies against virus has been held for over thirty years, however clinicopathological diagnosis are scarce. The frst reported case occurred in state Paraná 2001, confrmed isolation and serotype 12 BTV. Rio Grande do Sul, 2009, two outbreaks was identifed 12. Serotype 4 isolated during an outbreak de Janeiro 2013. This study describes Diagnoses ovine...
The objective of this study was to evaluate the effects benzoic acid (BA) and essential oils (EO) on cellular humoral immune response, morphology, gene expression, antioxidant capacity in jejunal mucosa, cecal content microbiota weaned piglets growth performance from nursery finishing phase. One hundred twenty barrows were assigned three treatments a randomized block design: basal diet without additives (NC), with antibiotics (PC), 0.3% BA EO (BA+EO). pigs weighed 0, 42, 84, 132 days into...
