Eficácia do tetra-test como ferramenta de gestão da qualidade do leite cru refrigerado

The effectiveness of a new management tool for screening refrigerated raw milk quality in a dairy industry is provided. Three hundred and seventy-four samples of raw milk from individual producers and 125 samples from bulk milk carriers from the same producers were analyzed. Producers' samples underwent a fast tube reduction test, or Tetra-Test, to estimate total bacteriological charge and their predominant microbiota. Bulk milk samples underwent standard plate count (SPC) as reference method. Tetra-test was effective in screening and assessing the microbiological quality of refrigerated raw milk, since 82.4% of samples with more than 106UFC/mL were readily detected (5 minutes to 2h). The test may be employed as a management tool either in screening or in interventions on the detected problem. In fact, its results provided complementary information on the characteristics of dominant microbiota. Most samples failed in compliance to IN 51 requirements. Further, 211 samples (56.4%) showed high microbial charge and, consequently, poor quality raw milk. Psychrotrophic groups were not yet the main degrading factors of cooled raw milk, albeit present in 76.8% of samples.

Parâmetros bioquímicos de avaliação da função renal e hepática de equinos com cólica submetidos a laparotomia, sobreviventes ou não

We examined 46 adult horses - six healthy, as control, (group 1) and 40 horses with colic submitted to treatment by laparotomy. Twenty animals had no postoperative complication (group 2), and twenty died or were euthanized from seven to ten days after the surgery (group 3). There was an increase in serum urea and creatinine concentration and AST, FA and GGT activity of animals from group 1 and group 2, indicative of renal and hepatic injury. The changes were associated with dehydration and endotoxins. Depending on the severity of the colic, animals may develop kidney and liver failure.

Indicadores bioquímicos séricos e do líquido peritoneal de equinos submetidos à obstrução intestinal

Twenty-four horses were distributed into four different groups, instrumented control (GI), duodenum obstruction (GII), ileum obstruction (GIII) and large colon obstruction (GIV). Serum and peritoneal fluid analysis of aspartate aminotransferase, creatine kinase, lactate dehydrogenase, alkaline phosphatase, inorganic phosphorus and lactate were measured. Samples were collected one hour before the surgical procedure (T0); 3 hours after the obstruction (T3ob), 1, 3, 12, 24, 120 and 168 hours after the beginning of reperfusion/deobstruction. Duodenal (GII) and ileum (GIII) obstructions changed serum and peritoneal fluid biochemical analysis. However, only lactate, lactate dehydrogenase, creatine kinase and inorganic phosphorus concentrations were abnormal in peritoneal fluid three hours after the obstruction. The biochemical analysis of peritoneal fluid allowed a faster diagnostic of intestinal alterations than the serum analysis; hence it should be prioritized when pre-operatory colic assessment is carried out.

Efeitos do extrato de parede de levedura em dieta seca sobre a Microbiologia, ácidos graxos de cadeia curta e redução do odor das fezes de gatos adultos

The aim of this study was to evaluate the effects of yeast cell wall extract (YCW) in dry diet on the fecal microbiota, concentration of short-chain fatty acids (SCFA) and on the odor reduction of cats feces. We used 20 animals of both sexes, randomly assigned to four treatments and five repetitions totaling 20 experimental units: 1) dry commercial diet (control); 2) control + 0.2%, 3) control + 0.4%, and 4) control + 0.6% of YCW in dry matter. Enterobacteriaceae and lactic acid bacteria, fecal concentration of acetic, propionic and butyric acids, ammonia nitrogen and sensory panel were performed. There were no significant differences (p> 0.05) for bacterial counts and the concentration of SCFA and ammonia, but in sensory panel a reduction in the odor of feces could be noted with the use of 0.2% of YCW. We concluded that the addition of up to 0.6% YCW had no effect on the microbiology and the concentration of fatty acids, but there is potential for its use as an additive because of the improvement in the odor of feces. However, further studies are needed to understand the mechanisms of action and the effects of prebiotics for domestic cats.

Habilidades sociais e administração de tempo no manejo do estresse

Recent searches suggest that social skills and time management as control variables of stress. In order to analyze possible relations between these variables and stress, it was done a descriptive study with a sample of convenience. Eighty three freshmen students, both of gender, of Biology, Civil Engineering and Psychology answered the Stress Inventory (ISSL), Social Skills Inventory (IHS) and a Time Management Inventory adaptation (ADT). It is emphasized that methodology of adaptation, the pro rata system, was not based on high standards of psychometry, which can lead to change of configuration of the instrument and the data it provides. The most of participants were unde rthe media in Social Skills and 72,29% manage badly the time. The stress rate was 48,19%. It was found connection between bad time management and stress and the lack of social skills was associated to bad time management. There wasn't statistic connection between stress and social skills lack. Students in Civil Engineering had the smaller stress rate, as well as the bigger lack of a Social Skills category.

Síndromes oculares secundárias a infecção pelo Herpesvirus felino-1-Revisão

The feline infectious respiratory disease is the most common diagnosed infection in the veterinary clinic routine, being the Feline Herpesvirus1 the most important causal agent. Once infected, the cat will become a lifetime latent carrier, experiencing episodes of viral reactivation and spontaneous spread especially when there is a stress factor involved. This virus acts in the upper respiratory system and is also associated with eye diseases. The diagnosis is made by viral isolation and treatment protocol is based on a topic antiviral therapy, even though many of them are epiteliotoxic and may progress with intense discomfort in felines.The purpose of this paper is to describe the main ocular manifestations and syndromes seen in cats suffering from feline herpesvirus. Conjunctivitis, epithelial and stromal keratitis, corneal ulceration and indolent ulcers are the main ocular manifestations associated with viral infection, whereas symblepharon, keratoconjunctivitis sicca, proliferative keratitis and corneal sequestration are the main eye syndromes that can be observed in infected animals.

Bats (Mammalia: Chiroptera) from Guarulhos, state of São Paulo, Brazil

The present study provides a record of the bat fauna captured in Guarulhos, state of São Paulo, Brazil, between February and November 2011. The capture sessions were carried out using mist nets set on trails, around and above streams and lakes, near built areas and around livestock. After a total effort of 26,208 m2.h, we recorded 17 bat species belonging to Phyllostomidae (13 species), Vespertilionidae (3) and Molossidae (1). Sturnira lilium (73 captures), Artibeus fimbriatus (69), and A. lituratus (59) were the most abundant species, corresponding to 57.8% of all captures. Some information about shelters was also commented. This paper is the first to report Molossops neglectus for Guarulhos. © 2012 Check List and Authors.

A biópsia de linfonodo sentinela não deve ser recomendada para pacientes portadores de melanoma espesso

Objective: To ascertain whether there is any relationship between the state of the sentinel lymph node histopathology, recurrence and mortality from thick melanoma in patients undergoing SLNB over a long follow-up. Methods: Eighty-six patients with thick melanoma undergoing SLNB were selected from a prospective database. Lymphoscintigraphy, lymphatic mapping and intraoperative gamma probe detection were performed in all patients. The sentinel lymph node (SLN) was analyzed by HE and immunohistochemistry. Complete lymphadenectomy was indicated for patients with positive sentinel node. The histopathological SLN status was related to the rate of recurrence and mortality from melanoma. Results: One hundred and sixty-six SLNs were taken from the 86 patients. Ages ranged from 18 to 73 years. There were 47 women and 39 men. Micrometastases were found in 44 patients. Forty-two patients underwent complete lymphadenectomy. Seven other patients had positive lymph node. Among the 44 patients with positive sentinel node, there were 20 recurrences and 15 deaths. There were 18 recurrences and 12 deaths in the group with negative SLN. The Breslow thickness was not correlated with the histopathological SLN status. The histopathological SLN status did not affect the rates of recurrence and mortality (Fisher test, p = 1.00). The median follow-up was 69 months. Conclusion: Considering the lack of evidence of benefit, SLNB should not be indicated for patients with thick melanoma outside of clinical studies.
