-The objective of this research was to evaluate the quality of eggs from Dekalb White hens under different temperatures (room temperature, 25 ºC; and refrigeration, 8 ºC), storage times (7, 14 and 21 days), age of birds (35, 40, 45 and 50 weeks) and housing densities (625, 500, 416.6 and 357.14 cm 2 /birds). Haugh unit (HU) values and albumen height of 1,120 eggs from 528 laying hens, randomly allocated to four groups with different population densities were evaluated. The results showed a significant effect on Haugh units, between the time and storage conditions and between the ages of laying hens and storage condition. Eggs stored in refrigeration showed less weight loss and better Haugh unit indices when compared with eggs stored at room temperature. The increased time of storage, regardless of the temperature, caused loss in their quality. According to the results of this study, based on the evaluation of the albumen height, temperature, storage time, density and age of the layers influence the values of Haugh unit.

RESUMO -Esta pesquisa foi realizada com o objetivo de avaliar os aspectos produtivos e econômicos de poedeiras comerciais (Gallus gallus) submetidas a diferentes densidades de alojamento. Foram alojadas 264 poedeiras em gaiolas com dimensões de 100 cm × 50 cm × 40 cm em delineamento inteiramente casualizado, com quatro grupos distribuídos em esquema fatorial 4 × 4, com 8, 10, 12 e 14 aves por gaiola, correspondendo a 625, 500, 416,6 e 357,14 cm 2 /ave. As características avaliadas foram: produção de ovos, peso médio dos ovos, consumo de ração, massa dos ovos, conversão alimentar por dúzia e ovos imprestáveis para consumo humano. A densidade na gaiola teve efeito apenas sobre os ovos tipos extra e segunda e sobre a produção diária dos ovos tipo segunda, mas não influenciou as demais variáveis estudadas. Para poedeiras comerciais da linhagem Dekalb White, a utilização de gaiolas com a densidade de alojamento de 625, 500, 416,6 e 357,14 cm 2 /ave na fase de produção não prejudica os parâmetros de qualidade da produção, sob os aspectos zootécnico e econômico.Palavras-chave: densidade de alojamento, desempenho, gaiola, poedeiras Productive and economical aspects of laying hens submitted to different housing densitiesABSTRACT -The objective of this research was to study productive and economical aspects of laying hens (Gallus gallus) submitted to different housing densities. Two hundred and sixty-four laying hens were housed in cages with dimensions of 100 cm × 50 cm × 40 cm in a randomized complete design with four groups distributed in a 4 × 4 factorial arrangement, with 8, 10, 12 and 14 animals/cage, corresponding to 625, 500, 416,6 and 357,14 cm 2 /animal. The following characteristics were assessed: egg production, medium egg weight, feed intake, egg mass, feed conversion per dozen and inappropriate eggs for human consumption. Cage density only had an effect on the extra large and medium type eggs and on the daily production of medium type eggs, but did not influence the other variables studied. For laying hens of the Dekalb White lineage, the use of cages with housing densities of 625, 500, 416,6 and 357,14 cm 2 /animal in the production phase did not harm the quality parameters under the productive and economical aspects.

This work aims to detect the presence of Babesia canis vogeli in dogs from Recife, Pernambuco via molecular and parasitological detection methods, and to assess the risk factors associated with this parasite. A total of 146 dogs (male and female) of varying breeds and ages that presented clinical symptoms of babesiosis were assessed at a clinical care center in the Veterinary School Hospital. Blood was obtained via venopuncture for hemoparasite detection and polymerase chain reaction (PCR). Using a commercial kit, DNA was extracted from blood samples. For the PCR reaction, an approximately 590 base pair long genetic sequence was used to detect the presence of B. canis vogeli. The forward primer, denoted as BAB1 (5'-GTG AAC CTT ATC ACT TAA AGG-3'), was specific for a conserved region on the 18S rRNA gene of Babesia spp., and the antisense primer was denoted as BAB4 (5'-CAA CTC CTC CAC GCA ATC G-3'). PCR results suggested that the percentage of Babesia canis vogeli infection was 4.8%. Through descriptive statistical analysis of the data, we observed that there was higher frequency of parasite infection associated with male dogs above two years of age, with a defined breed, from the countryside, are domiciled, and also suffer from tick infestation. We conclude that regardless of the type of risk factor, babesiosis can be found throughout Recife, Pernambuco, and its prevalence does not vary in most regions of Brazil. Our results indicate that PCR is a sensitive test for the detection of blood parasites, and should be performed as a clinical routine.

Atualmente Médicos Veterinários atendem a animais de companhia, animais não convencionais e animais de produção, sendo desta forma, necessária a atualização e aprofundamento de seus conhecimentos para acompanhar o crescimento. A obtenção de conhecimento se inicia na faculdade com as práticas de ensino e se estende a vida profissional, através de especializações, pós-graduações e leitura de artigos, com esta visão foi compilado as pesquisas neste segundo volume de Estudos em Medicina Veterinária com temas inovadores dentro da clínica médica, nutrição, produtos de origem animal e práticas de ensino.

We characterized six drug-resistant nosocomial isolates of Klebsiella pneumoniae obtained in a hospital located in northern Minas Gerais State, Brazil, by determining their antibiotic sensitivity profiles, detecting the bla KPC genetic marker and examining their clonal relationships. All isolates were found to be extensively drug resistant. A PCR assay was used to confirm the identity of the isolates as K. pneumoniae and assess the bla KPC gene. All isolates tested positive for the bla KPC gene, which is related to carbapenem resistance. The genetic profiles and clonal relationships among the isolates were evaluated by ERIC-PCR. All the isolates were in a single group with two distinct subgroups. Analysis of the ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (1): gmr18172 E.R. Lima et al. 2 genetic diversity among the isolates revealed that five of the six were clones, which suggests cross-transmission in this hospital environment. Five of the patients died from infection. We describe the first detection of KPC-producing K. pneumoniae isolates from a hospital in northern Minas Gerais state.

Concern with antimicrobial resistance in animal production systems increases the interest toward integrative therapies. The objective of the present report was to report an integrative approach to a goat undergoing rumenotomy. A goat with ruminal acidosis underwent rumenotomy, corrective rumen suture, moxibustion, and treatment of the surgical wound (TFO) with sugar. In the first twenty days, acupuncture was performed on ST36, indirect moxibustion on Sp6 and CV8, and TFO with antibiotic ointment and sugar. The wound contracted 2cm, there was gradual return of ruminal dynamics, and moderate pain. Acupuncture continued from D21 to D50 on Yin tang, BL13, BL20, BL23, and BL22. Although there was drainage of ruminal fluid, the wound contracted 4cm during this period, pain was absent, and ruminal dynamics normal. During the last thirty days, the acupuncture technique surround the dragon was used and BL13 point needled, with complete closure of the wound. The TFO from D21 was performed solely with sugar. During treatment, there was modulation of the inflammatory response, with formation of granulation tissue and neovascularization. On D84, fibrinogen was 100mg/dL. The authors conclude that the use of sugar, acupuncture, and moxibustion contributed to return of normal ruminal motility, wound contraction, and complete tissue reepithelization.

Joint diseases are relatively common in domestic animals, such as dogs. The involved inflammation produces thermal emission, which can be imaged using specific sensors that allow capturing of infrared images. Given that there have been few reports on the use of thermography in the diagnosis of inflammation associated with diseases of the hip joint in dogs, we here propose a method for identification of inflammatory foci in dogs by using infrared thermometry. The present study aimed to find non-invasive and low-cost resources that couldfacilitate a clinical diagnosis in cases withinflammation in the coxofemoral joint of dogs.To this end, we developed a system in whichthe Flir Systems TG165 thermograph is coupled to a black PVC cannula with a 30-cm focus-to-animal distance.External effects of the environment on the temperature of the animalswere compared with the body temperature as measured by a conventional thermometer.Thirty-one dogs with and without inflammation in the coxofemoral joint underwent clinical evaluation.We verified that the temperature registered by the thermograph inthe animals with joint inflammation was significantlydifferentfrom that incontrol animals without inflammation, in the lateral projection.The method showed a sensitivity of 80%, specificity of 87.5%, and accuracy of 83.87%. This standardized method of diagnosis of inflammatory foci in the coxofemoral articulation of dogs by way of thermography showed sensitivity, specificity, and satisfactory accuracy. ResumoTentando buscar recursos não invasivos e de baixo custo, para auxiliar o diagnóstico clínico em casos de inflamação na articulação coxofemoral de cães, idealizou-se o presente trabalho, que teve como objetivo propor um método de diagnóstico, em casos de inflamação na articulação coxofemoral de cães, desenvolvido a partir do registro do aumento da temperatura no local da inflamação, mediante o emprego de um termógrafo do tipo TG165 da Flir Systems acoplado a uma cânula de PVC, negra, com 30 cm de distância foco-animal para diminuir os efeitos externos que o ambiente exerce sobre a temperatura dos animais, e comparando-a com a temperatura corpórea, aferida por um termômetro convencional. Foram submetidos à avaliação clínica, 31 cães com e sem inflamação na articulação coxofemoral, onde verificou-se que a temperatura, registrada pelo termógrafo, dos animais pertencente ao grupo com inflamação na articulação apresentou diferença significativa na projeção lateral, em relação a temperatura dos animais do grupo sem doença articular, também aferida através do aparelho termográfico. O método apresentou sensibilidade de 80%, especificidade de 87,5% e precisão de 83,87%. Conclui-se que a padronização do método de diagnóstico de focos inflamatórios na articulação coxofemoral de cães pela termografia apresentou sensibilidade, especificidade e precisão satisfatória.

Com o objetivo de avaliar os aspectos clínicos, hematológicos, bioquímicos e citopatológicos de cães com tumor venéreo transmissível (TVT) tratados com o sulfato de vincristina foram selecionados 10 cães sem distinção de sexo, raça ou idade que tiveram o diagnóstico de TVT pelo exame citopatológico, dos quais foram colhidas amostras de sangue para realização de hemograma e dosagens bioquímicas. Os cães foram tratados com o sulfato de vincristina na dose de 0,75mg/m2 com administração intravenosa a cada sete dias durante seis semanas. Dos 10 cães avaliados e acometidos pelo TVT, 70% eram fêmeas e 30% machos, com média de idade de 4,8±1,3 anos e todos sem raça definida. A principal queixa clínica foi secreção sanguinolenta, nasal e/ou genital. Após a quimioterapia, apenas o sangramento vulvar apresentou diferenças estatisticamente significativas (p<0,05) a partir de 21 dias, onde 100% dos cães não apresentaram mais sangramentos. Na classificação citopatológica, observou-se que 50% dos tumores foram do tipo plasmocitário, 30% misto e 20% linfocitário. A alteração hematológica observada foi à diminuição na contagem dos bastonetes (p=0,042) no início e após sete dias, enquanto que na bioquímica sérica foi constatado aumento na dosagem sérica de fósforo (p=0,024) com resultados estatisticamente significativos (p<0,05). Concluiu-se que a citologia aspirativa por agulha fina e o imprint foram métodos eficazes, simples e seguros para o diagnóstico do TVT e que independente da classificação tumoral, houve resposta satisfatória de todos os pacientes ao tratamento com o sulfato de vincristina. Um protocolo a partir de seis aplicações do quimioterápico, com intervalos de sete dias entre as aplicações se mostrou eficiente para o tratamento do TVT com regressão completa da neoplasia.
