O Toxoplasma gondii e um coccidio intestinal intracelular obrigatorio dos felideos, de distribuicao cosmopolita, descoberto em 1908 por Nicolle & Manceaux. O primeiro relato na especie canina ocorreu em 1910, na Italia e, no Brasil em 1911. Objetivando-se avaliar a frequencia deste parasito, na populacao de caes errantes da cidade de Salvador-Ba, foram coletadas 225 amostras de sangue, de animais provenientes de 10 distritos sanitarios. Os soros foram submetidos a reacao de imunofluorescencia indireta ( ...

The frequency of antibodies to Neospora caninum (Protozoa: Apicomplexa) in dog sera was investigated. Blood samples from 100 mongrel dogs, captured in the streets of Sao Luis, State of Maranhao, were analized using imunofluorescent antibody test. Forty five percent of the dogs were positive, and the titers ranged from 1:50 to 1:800. No sex difference was observed for frequency of N. caninum (60% in males and 40% in females). This is the first report of antibodies to N. caninum in dogs from Maranhao.

Sera from 384 dairy goats in nine herds from Bahia State, Brazil, were assayed for Neospora caninum antibodies using an indirect immunofluorescent antibody test (IFAT). Animals were selected and divided in groups by age and breed. Antibodies against N. caninum were found in 15% (58/384) of goats. Serum titers ranged from 1:100 to 1:3200. There was no significant difference between the age groups. Seroprevalence was higher in Alpine breed (24%) than in Saanen (14%) and Nubian (3%) breeds. The 58 N. caninum- ...

A mortality episode of endemic and endangered psittacine birds from the genera Ara and Amazona occurred during January 2015. The birds were housed in a management unit for wildlife conservation that receives wild-caught birds from illegal trade. In total, 11 (57%) adult birds of different origins that shared these accommodations died. Only four of them were sent for diagnosis. The main lesions found at necropsy were consistent with those described previously for avian chlamydiosis; the presence of ...

Neospora caninum is a protozoan parasite that causes disease in domestic and wild animals. The purpose of the present work was to investigate the frequency of antibodies anti-N. caninum in water buffaloes in Bahia state, Brazil. Blood samples were collected from 117 animals distributed in four farms. The sera were tested using an immunofluorescent antibody technique. Antibodies were detected in 35.9% of the animals using a serum dilution of 1:200 as a cutoff. The titers ranged from 1:200 to 1:800. ...

The purpose of this study was to investigate whether sporulated Neospora caninum oocysts, which had been stored for 46 mo in a 2% sulfuric acid solution at 4â, remain morphologically viable and infective to gerbils (Meriones unguiculatus). Six gerbils were orally inoculated with doses of 400 or 1,200 oocysts. Two mo after inoculation, the animals did not show any clinical signs, had no histological lesions, and were seronegative for N. caninum at 1: 50 in an immunofluorescent antibody test. PCR ...

ABSTRACT: Bovine dermatophilosis is a dermatitis characterized by typical focal or localized lesions with “paintbrush” aspect and occasionally as disseminated cutaneous disease. We report the case of a one-year-old Nelore female with history of chronic cutaneous disseminated lesions that appeared immediately after a rainfall period. Serous to purulent exudates, hair with tufted appearance, hyperkeratotic, non-pruritic, hardened, yellowish to brown, and coalescent crusty lesions were observed distributed ...

Purification of a lectin from Bothrops jararacussu venom (BjcuL) was carried out using agarose-D-galactose affinity gel. MALDI-TOF gave a major signal at m/z 32028, suggesting the presence of a dimmer composed of two identical subunits. Divalent cations were required for the lectin activity, as complete absence of such ions reduced hemagglutination. BjcuL was more effective at neutral pH and showed total loss of activity at pH values below 4.0 and above 9.0. Its agglutinating activity remained stable ...

GABA (γ-amino butyric acid) is the major inhibitory transmitter in the central nervous system and its action is terminated by specific transporters (GAT), found in neurons and glial cells. We have previously described that GAT-3 is responsible for GABA uptake activity in cultured avian Müller cells and that it operates in a Na(+) and Cl(-) dependent manner. Here we show that glutamate decreases [(3)H] GABA uptake in purified cultured glial cells up to 50%, without causing cell death. This effect is ...

Abstract Soil organic carbon (SOC) information is fundamental for improving global carbon cycle modeling efforts, but discrepancies exist from country‐to‐global scales. We predicted the spatial distribution of SOC stocks (topsoil; 0–30 cm) and quantified modeling uncertainty across Mexico and the conterminous United States (CONUS). We used a multisource SOC dataset (>10 000 pedons, between 1991 and 2010) coupled with a simulated annealing regression framework that accounts for variable selection. Our ...

Metal-halide perovskites compounds, such as CsSnX3 (X = halogen), have attracted a lot of attention as a photovoltaic material due to their astonishing optoelectronic properties, nevertheless, the improvement of its efficiency is still an issue. It has been observed that the mixing of halogens in the perovskite structure increases the compound stability. However, theoretical studies of the effects of this mixing are scarce; by understanding the most stable mixing positions it would be possible to enhance ...

We report the synthesis of xCuO/TiO2-ZrO2 catalysts containing 1, 5 and 10 wt % CuO by the sol-gel method. The solids were dried at 100 °C for 24 h and calcined at 400 °C for another 24 h in an open-air atmosphere. Part of these samples was impregnated with 0.5 wt % of PtO by the wet impregnation method. Samples were characterized by H2-TPR, TPD-CO2, SEM, TEM, XRD and 2-propanol decomposition. Our H2-TPR results indicate that Pt impregnation on the xCuO/TiO2-ZrO2 system promotes the CuO reduction at lower ...

This contribution presents an infinite-horizon optimal tracking controller for nonlinear systems based on the state-dependent Riccati equation approach. The synthesized control law comes from solving the Hamilton-Jacobi-Bellman equation for state-dependent coefficient factorized (SDCF) nonlinear systems. The proposed controller minimizes a quadratic performance index, whose entries are determined by the particle swarm optimization (PSO) algorithm in order to improve the performance of the control ...

Abstract Photodynamic therapy has been used to treat a variety of diseases, however, there is continuing search for new biocompatible photosensitizers. Herein, we demonstrate for the first time that imidazo[1,2‐ a ]pyrimidine compounds are able to generate singlet oxygen species and can act as photosensitizers in the intracellular environment. Our results show that this class of compounds absorb and emit in the 400–500 nm region, present low cytotoxicity in the dark, are efficiently uptaken by cells, ...

Neospora caninum was isolated from the brain of an adult dog in Brazil. Cerebral tissue from the dog was inoculated into Mongolian gerbils. Gerbils were euthanized 3–4 months later and bradyzoite-containing tissue cysts were observed in their brains. N. caninum (designated NC-Bahia) was isolated in cell culture after inoculation with tissue cysts from the gerbils. The identity of the parasite was confirmed by immunohistochemical examination and polymerase chain reaction (PCR). Gerbils may be a useful ...

Long-term effects of COD/N ratios on the nitrogen removal performance and bacterial community of an anammox reactor were evaluated by adding a synthetic medium (with glucose) and real anaerobic effluent to a SBR. At a COD/N ratio of 2.8 (COD, 390 mg·L−1) ammonium removal efficiency was 66%, while nitrite removal remained high (99%). However, at a COD/N ratio of 5.0 (COD, 300 mg·L−1), ammonium and nitrite removal efficiencies were high (84% and 99%, respectively). High COD, nitrite, and ammonium removal ...
