1. Alternative methodologies for genotyping polymorphisms in the CAST and CAPN1 genes in beef cattle
ABSTRACT The objectives of this study were to genotype single nucleotide polymorphisms (SNP) AF159246:g.2959A>G (CAST/DdeI) and AF248054.2:g.6545C>T (CAPN4751) in beef cattle by PCR-RFLP (Polymerase Chain Reaction - Restriction Fragment Length Polymorphism), using the restriction enzyme DdeI for both SNP, and describe the use of these genotyping methodologie

2. An evaluation of immunomagnetic separation-real-time PCR (IMS-RTiPCR) combined assay for rapid and specific detection of Escherichia coli O157:H7 in raw milk and ground beef
Abstract The aim of this study is to optimize a rapid and specific method for detection of E. coli O157:H7 (EHEC) from food samples with high background flora using an immunomagnetic separation-real-time polymerase chain reaction assay (IMS-RTiPCR). For this, EHEC cells were recovered from raw milk and ground meat samples that were artificially contaminated

3. Bovine alphaherpesvirus 1 and 5 in semen from bulls presenting genital lesions under field conditions in Brazil
RESUMO Os alfa-herpesvírus bovinos 1 e 5 (BoHV-1/5) são importantes patógenos de doença respiratória, reprodutiva e neurológica em bovinos. O objetivo deste estudo foi investigar a frequência de detecção de anticorpos neutralizantes contra BoHV-1/5 em amostra de soro e detectar DNA viral em sêmen de touros do rebanho bovino localizado nas fazendas

4. Sensory characteristics of Musculus longissimus thoracis et lumborum of bovine Nelore adult matured
Abstract The goal of this paper was to perform the sensory evaluation of strip loin from adult Nelore cattle on the acceptance perspective of the consumer from Aracaju and purchase intention faged beef in different cutting thicknesses. Musculus longissimus thoracis and lumborum were used in three treatments with zero aging time with cutting thickness of 2.5

5. Nursing infant with acquired toxoplasmosis in the first months of life – a case report
ABSTRACT Toxoplasmosis is caused by Toxoplasma gondii and the probability of this infection occurring in the first months of life is usually low because its transmission is related to eating habits. A 6-month-old nursing infant was diagnosed with acute toxoplasmosis, which was identified through anti- T. gondii IgA, IgM and low-avidity IgG serologic assays,

6. Segmentation of the buffalo meat consumer market in Belém, Pará, Brazil
ABSTRACT The objective of this study was to identify different market segments for buffalo meat with target groups defined in the city of Belém, Pará, Brazil. Paired samples of beef and buffalo meat were given to 447 volunteers, and a sensory analysis of the products was conducted. After the tasting, a questionnaire was administered to obtain demographic (

7. Prevalence and quantification of Listeria monocytogenes in beef offal at retail level in Selangor, Malaysia
A total of 63 beef offal samples (beef liver = 16; beef lung = 14; beef intestine = 9; beef tripe = 15; beef spleen = 9) from three wet markets (A, B, and C) in Selangor, Malaysia were examined for the prevalence and microbial load of Listeria monocytogenes. A combination of the most probable number and polymerase chain reaction (MPN-PCR) method was employed

8. In vitro detection of pathogenic Listeria monocytogenes from food sources by conventional, molecular and cell culture method
Among current in vitro methods for identification of pathogenic Listeria monocytogenes (L. monocytogenes) rely on growth in culture media, followed by isolation, and biochemical and serological identification. Now PCR (Polymerase Chain Reaction) has been used for the rapid, sensitive and specific detection of pathogenic L. monocytogenes. The pathogenicity of

9. The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis

12. Association of polymorphisms in the leptin and thyroglobulin genes with meat quality and carcass traits in beef cattle
The objective of the present study was to estimate the allelic and genotypic frequencies of the polymorphisms E2FB (AY138588.1: c.305C> T), located in the leptin gene (LEP), and TG5 (X05380.1:g.-422C>T), located in the thyroglobulin gene (TG), and evaluate the association of these polymorphisms in crossbred cattle of seven distinct genetic groups with the fo
