13. Proposal for a New Histological Scoring System for Cartilage Repair
OBJECTIVE: This study aimed to develop a new histological scoring system for use in a partial-thickness cartilage repair animal model. Although previous papers have investigated the regeneration of articular cartilage, the good results achieved in small animals have not been replicated in large animal models or humans, possibly because of the frequent use o

14. Molecular characterization of ureaplasmas isolated from reproductive tract of goats and sheep from Brazil
Abstract Ovine/caprine ureaplasmas have not yet been assigned a species designation, but they have been classified into nine serotypes. Herein ureaplasmas were searched for in 120 samples of vulvo vaginal mucous from sheep and 98 samples from goats at 17 farms. In addition, semen samples were collected from 11 sheep and 23 goats. The recovered ureaplasma wer

15. Malignant Catarrhal Fever in Brazilian cattle presenting with neurological syndrome
Abstract Malignant Catarrhal Fever (MCF) was investigated in the central nervous system of cattle with neurological syndrome. Two-hundred-ninety samples were analyzed by histology, and molecular methods to detect ovine herpesvirus type 2 (OvHV-2) were optimized and validated. The qualitative polymerase chain reaction (qualitative PCR) analytical sensitivity

16. Evaluation of QuEChERS Sample Preparation for Determination of Avermectins Residues in Ovine Muscle by HPLC-FD and UHPLC-MS/MS
A fast and sensitive method using high performance liquid chromatography-fluorescence detection (HPLC-FD) and ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) was developed and validated for the determination of avermectins residues in ovine muscle samples. QuEChERS (quick, easy, cheap, effective, rugged and safe) sample pr

17. Reversible atrial fibrillation following Crotalinae envenomation
Abstract Background Cardiotoxicity is a documented complication of Crotalinae envenomation. Reported cardiac complications following snake envenomation have included acute myocardial infarction, electrocardiogram abnormalities and arrhythmias. Few reports exist describing arrhythmia induced by viper envenomation and to our knowledge none describe arrhythmia

18. FabAV antivenin use after copperhead snakebite: clinically indicated or knee-jerk reaction?
Abstract Background Crotalidae Polyvalent Immune Fab (Ovine) (FabAV) antivenin is commonly recommended after pit viper snakebites. Because copperhead envenomations are usually self-limited, some physicians are reluctant to use this costly treatment routinely, while others follow a more liberal approach. We hypothesized that, in practice, only patients with

19. Effect of Fibroblast Growth Factor 2 (FGF2) and Insulin Transferrin Selenium (ITS) on In Vitro Maturation, Fertilization and Embryo Development in Sheep
The present study evaluated the effect of fibroblast growth factor 2 (FGF2) and insulin-transferrin-selenium (ITS) to the in vitro maturation and embryo culture media on ovine oocyte maturation, cleavage and embryo development. Oocytes having more than five layers of unexpanded cumulus cells and granular homogenous ooplasm were cultured into 50 μL droplets

20. Virulence factors and antibiotic resistance of Helicobacter pylori isolated from raw milk and unpasteurized dairy products in Iran
Background Despite the high importance of Helicobacter pylori, the origin and transmission of this bacterium has not been clearly determined. According to controversial theories and results of previous studies, animal source foods – especially milk – play an important role in the transmission of H. pylori to humans. The aim of the present study was to

21. Genomic variation and population structure detected by single nucleotide polymorphism arrays in Corriedale, Merino and Creole sheep
The aim of this study was to investigate the genetic diversity within and among three breeds of sheep: Corriedale, Merino and Creole. Sheep from the three breeds (Merino n = 110, Corriedale n = 108 and Creole n = 10) were genotyped using the Illumina Ovine SNP50 beadchip®. Genetic diversity was evaluated by comparing the minor allele frequency (MAF) among b

22. SUBSTITUIÇÃO DO CONCENTRADO POR NÍVEIS CRESCENTES DE SILAGEM DE GLIRICÍDIA NA ALIMENTAÇÃO DE CORDEIROS. / REPLACEMENT OF THE CONCENTRATE BY DIFFERENT LEVELS OF GLIRICIDIA SILAGE IN LAMBS FEEDING.
Objetivou-se avaliar a substituição do concentrado pela silagem de Gliricídia (Gliricidia sepium) em dietas de cordeiros em fase de crescimento sobre o consumo de matéria seca, ganho de peso, conversão alimentar . Foram utilizados 27 cordeiros da raça Santa Inês, não castrados, recém desmamados, com peso médio inicial de 14,5 kg e com idade aproxim

23. Suplementação nutricional com probiótico com ou sem adição de zinco na produção de anticorpos séricos contra o vírus rábico em ovinos vacinados contra raiva / Nutritional supplementation with probiotics with or without added zinc on production of sericos antibodies against the virus rabico in ovine vaccinated against rabies
Esse estudo avaliou o efeito da suplementação do probiótico com ou sem zinco (Zn), adicionado à mistura mineral, na produção de anticorpos séricos contra o vírus rábico em ovinos vacinados com uma única dose de vacina. Quarenta e cinco ovinos machos, mestiços Santa Inês, com idade de 6 meses foram divididos aleatoriamente em 3 grupos (15 ovinos/g

Two experiments were conducted to analyze the expression of genes related to follicular development and subsequent reproductive efficiency in oocytes and cumulus cells in two distinct phases of folliculogenesis. Ovaries of native breeds of sheep slaughtered in the abattoir in Caruaru/PE were collected and transported to the Laboratory of Applied Molecular An
