SummaryThe quality of meat is a multifactorial parameter dependent on the perspective and goals of the link in the production chain. Generally, a variety of factors directly or indirectly affect the quality characteristics of meat and, therefore, the value of meat products. Often, the literature divides the interfering factors into intrinsic and extrinsic. Intrinsic factors are related to animals; therefore, intrinsic factors are less variable. These factors include breed, sex, age, weight, genes, and type of muscle fiber. Some of these factors are not well studied, others have variable influence or are controversial and only a few are known and sometimes controlled. Thus, this study aimed to review some intrinsic factors that influence the quality of lamb meat. Keywords: cooking losses, meat color, tenderness, water holding capacity.

A 47-y-old man was bitten by a reduviid bug from the Zelus Fabricius, 1803 genus, which was hidden inside a rubber-coated boot. The bite caused immediate and sharp pain, followed by local edema and constant pruritus for 15 d. Pain and fever within the first 24 h were managed with analgesics as needed, and resolution was complete and without sequelae after 21 d.

The occurrence of Leptospira and of seroreactivity against Leptospira was investigated in animals and humans from six farms located in two Brazilian biomes that have different geoclimatic conditions: Pantanal -municipalities of Miranda (MS), Itiquira (MT) and Poconé (MT) and Caatinga -municipalities of Sobradinho (BA), Garanhuns (PE) and Sobral (BA). Blood and urine samples of wildlife, domestic animals and humans were collected at each property. The samples were collected from February to April 2012 in Caatinga and from July to September 2012 in Pantanal. The serological reactivity against Leptospira spp. was verified by microscopic agglutination technique (MAT) made with a collection consisting by 24 antigens of Leptospira spp. The leptospires research was carried out by urine samples crop sown in Fletcher resources and Ellinghausen -McCullough -Johnson -Harris (EMJH). Crops with growth of leptospires were referred to the Leptospirosis Laboratory of the Institute of Pathobiology, National Institute of Agricultural Technology, Buenos Aires, Argentina and isolated Leptospira strains were genotyped with the technique of Multiple Locus Variable Number Tandem Repeat Analysis (MLVA). The classification procedure employed the VNTR 4, 7, 9, 10, 19, 23, 31, LB4 and LB5, which discriminate strains of L. interrogans and L. borgpetersenii. In Pantanal, 17 wildlife, 65 domestic animals and two humans were examined. In Caatinga, seven wild animals were examined, along with 100 domestic animals and 26 humans. Of 84 blood samples tested in Pantanal, 47 (55.95%) were positive and, of 133 in Caatinga, 59 (44.36%) were reactant. By Fisher's exact test, considering a 0.05 significance level, there was no difference between the proportions of serum reagent animals against Leptospira spp. in two biome reviews (p = 0.063). The predominant serovars in SAM reactions were: 1) Pantanal -Bratislava (wildlife, dogs and humans), Grippotyphosa (horses and cattle); 2) Caatinga -Copenhageni (humans and dogs), Patoc (horses and cattle), Panama (sheep and goats), Patoc, Copenhageni and Australis (wildlife). Four strains of Leptospira were isolated: two in Sobradinho, BA, L. interrogans serogroup Pomona in Cavea aperea and L. interrogans in Euphractus sexcinctus; and two in Sobral, CE, L. interrogans in Cerdocyon thous and L. interrogans serogroup Pomona in Euphractus sexcinctus.

The aim of this study was to describe the isolation of a pathogenic strain of Leptospira interrogans
