The origin of Vaccinia virus (VACV) outbreaks in Brazil remains unknown, but since the isolation VACV Mus musculus mice during a zoonotic outbreak affecting cattle and milkers, peridomestic rodents have been suggested to be link between cows wild animals. Considering that experimentally infected eliminate viral particles their feces, we investigated presence feces urine were captured forest areas surrounding milking farms central west region São Paulo State. For first time, this work reports...
The experiment evaluated the influence of isolated or associated phytogenic additives (PA) and organic acids (OA) on nutrient digestibility, performance carcass characteristics broiler chickens. Two experiments were conducted in a completely randomized design with 2 × + 1 factorial arrangement treatments (with without PA OA antibiotic enhancer anticoccidial). In first experiment, two metabolic tests to determine metabolizability coefficients nutrients starter growth diets. second 2520...
The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects heat stress, applied between 28 42 days age, on performance, carcass meat quality traits broiler chickens. A total 384 male chickens were assigned completely randomized design, 2×3 factorial arrangement (diet or without vitamin supplementation two ambient temperatures plus pair-feeding group) 16 replicates. Chickens kept in thermoneutral conditions up...
Q fever is an important zoonosis, yet it often neglected and can present large outbreaks, as observed in the Netherlands. In past few years, cases of have been described Brazil; however, epidemiological situation ruminants, main reservoir pathogen, unknown this country. Our study aimed to estimate prevalence C. burnetii cattle sent slaughterhouses using immunofluorescence assay (IFA) quantitative real-time PCR (qPCR). From 1515 serum samples collected from nine slaughterhouses, 23.8%...
Abstract Coxiella burnetii is a zoonotic pathogen with worldwide distribution that responsible for Q fever in humans. It highly infectious bacterium can be transmitted from cattle to humans through the consumption of unpasteurized milk. We report molecular identification C. raw cow's milk being sold directly human Brazil without official inspection or pasteurization. One hundred and twelve samples were analysed by real‐time quantitative PCR (qPCR), was detected 3.57% (4/112) at concentration...
This study aimed at evaluating the effect of nucleotides on performance and carcass yield broilers fed diets with no antibiotic growth promoters (AGP), anticoccidials, or animal feedstuffs. In trial, 600 Ross 308 male were distributed in a completely randomized experimental design into six treatments four replicates 25 birds each. Treatments consisted control diet (CD), CD + AGP, 0.04%, 0.05%, 0.06%, 0.07% nucleotides. The did not contain vaccinated against coccidiosis three days age. No...

Outbreaks of Vaccinia virus (VACV) affecting cattle and humans have been reported in Brazil the last 15 years, but origin outbreaks remains unknown. Although VACV DNA already detected mice (Mus musculus), opossums (Didelphis albiventris) dogs during zoonotic outbreaks, no transmission to or from any these were Brazilian outbreaks. In this work, we assessed PCR positivity blood samples cows other domestic mammals, wild rodents areas with without infection reports. Our results show detection...
Summary Stable isotope analyses have helped in assessing dietary switches if the diet undergoes metabolic alteration (isotopic exchange). However, when considering effects over time of switching from one to another, can assess how quickly new is incorporated into tissues via isotopic renewal or incorporation rate, turnover. Turnover obtained using exponential curves that fit original data, allowing determination practical order parameters such as half‐life ( T ) and turnover constant k )....
O objetivo deste trabalho foi avaliar o efeito da dieta suplementada com nucleotídeos sobre taxa de turnover mucosa intestinal frangos antes e após lesões causadas por coccidiose meio análise isotópica, utilizando a variação do carbono-13 em plantas C3 C4. Foram utilizados 264 pintos submetidos dois tratamentos: controle 0,07% nucleotídeos. Os possuíam sinais isotópicos seus tecidos semelhantes ao ditas Após alojamento, para mucosa, as aves receberam dietas predominantemente C3. Com 16 dias...
Este trabalho objetivou determinar o turnover do carbono no Pectoralis major, quilha, tíbia e fígado de frangos corte em seus diferentes períodos crescimento, utilizando a técnica dos isótopos estáveis. Foram utilizados 216 pintos corte, machos, Cobb. O delineamento experimental foi inteiramente casualizado consistiu sete tratamentos com dias substituição das dietas distintos: 0; 7; 14; 21; 28; 35; 42 idade. Para mensurar nos tecidos determinado intervalo tempo, utilizado modelo sigmoidal...
Abstract The aim of this study was to evaluate the effect phytogenic additives and glutamine plus glutamic acid, associated or not, on histomorphometry bursa Fabricius small intestine, oocyst count lesion scores, carbon turnover duodenal mucosa broiler chickens infected with Eimeria acervulina. A total 450 male distributed into a completely randomized design six treatments three replications.

This paper describes the control, epidemiological, pathological, and molecular aspects of an outbreak meningoencephalitis in calves due to bovine herpesvirus 5 at a feedlot with 540 animals São Paulo State, Brazil. The introduction new contact between resident introduced ones were most likely responsible for virus transmission. Bovine 1 vaccine was used, resulting efficacy although two positive animals, vaccinated revaccinated, presented meningoencephalitis, thereby characterizing vaccinal failure.
