Objetivou-se com este estudo investigar a participação de Toxoplasma gondii em falhas reprodutivas em pequenos ruminantes de criatórios situados na Zona da Mata e no Agreste do Estado de Pernambuco e que apresentavam histórico de distúrbios reprodutivos. Foram selecionadas 12 propriedades das quais se coletaram amostras de 262 animais, sendo 167 caprinos e 95 ovinos. Realizou-se a pesquisa de anticorpos anti-Toxoplasma gondii, utilizando-se a técnica da Imunofluorescência Indireta (RIFI). Foram aplicados questionários investigativos nas propriedades visitadas para identificar os fatores de risco associados à infecção. em 100% das propriedades foram encontrados animais soropositivos. Para T. gondii, das 167 amostras de soro caprino analisadas, 31,7% foram positivas, enquanto que na espécie ovina, das 95 amostras, 16,9% foram positivas. Para a espécie ovina, não foram observadas associações significativas. Para os caprinos, houve associação significativa (p<0,05) para as variáveis: manejo intensivo (OR=2,40), exploração leiteira (OR=2,10), animais procedentes de outros estados (OR=7,89) e monta natural (OR=5,69). Conclui-se que a infecção pelo T. gondii encontra-se disseminada nos rebanhos de caprinos e ovinos estudados e que medidas sanitárias devem ser adotadas para controlar os fatores de risco identificados neste estudo.

Com o objetivo de comparar variáveis epidemiológicas na toxoplasmose em ovinos e caprinos, amostras de soro de animais de propriedades localizadas em duas regiões do Estado de Pernambuco, Brasil, foram testadas pela reação de imunofluorescência indireta (RIFI) para detecção de anticorpos anti-Toxoplasma gondii. Dos 173 soros ovinos testados, em 35,3% foram encontrados resultados positivos, enquanto 40,4% dos 213 soros caprinos foram positivos à RIFI. em ovinos, associações significativas foram encontradas para sexo e raça, mas não para região, tipo de manejo ou falha reprodutiva. Os resultados da RIFI para os caprinos foram significativamente associados ao sexo, raça, região, tipo de manejo e de exploração, mas não com a ocorrência de falhas reprodutivas.

A infecção por Neospora caninum é uma importante causa de abortos em bovinos, assim como mortalidade neonatal em caprinos e ovinos. Uma pesquisa sorológica de anticorpos anti-N. caninum foi realizada no município de Ibimirim (PE, Brasil). Os resultados ao teste de imunofluorescência revelaram que 26,6% (85/319) dos caprinos e 64,2% (52/81) dos ovinos foram positivos. A reatividade à sorologia foi associada com a idade nos caprinos (p < 0,01) e ovinos (p > 0,05), com maior ocorrência nos animais mais velhos. Estes resultados indicam exposição a N. caninum entre pequenos ruminantes na área estudada.

The present study had as objective contribute to the characterization of beekeeping in the Pernambuco State and evaluate the physical-chemical quality of the honeys produced in the region. For this, was applied a directed formulary to the representative organ of beekeeping class aboutthe productives and technicals aspects of beekeepers. Was obtained 14 samples of honey by Apis mellifera africanized, stored in sterile plastic vessels was sent to the Beekeeping Products Quality Control Laboratory (CEA-UNITAU). Was observed that the most of beekeepers have of 50 to 100 hives (57,14%), 28,57% of 100 to 200 hives and 14,28% more than 500 hives, being that 85,71% produce 30 to 50 kg honey/hives/flowering. All use the standard hive Langstroth and 85,71% obtain their swarm by capture. About the physical-chemical quality of the honey, was observed that moisture content varied from 18,2% to 22,0%, with mean value of 19,80±1,11; the water activity varied from 0,70 to 0,84 aw, with mean value of 0,79±0,05 aw; the total acidity was 24,91±8,99 meq/kg and the average index of hydroxymethylfurfural was 16,32±17,88 meq/kg. The results obtained are according to the quality limits established by the brazilian legislation, excepted the water activity that exceeded the maximum limit of 0,65 aw. The datasobtained in this paper shows the development of beekeeping in Pernambuco State and the honey presents nice quality.

Knowing the annual climatic conditions is of great importance for appropriate planning in agriculture. However, the systems of climatic classification are not widely used in agricultural studies because of the wide range of scales in which they are used. A series with data from 20 years of observations from 45 climatological stations in all over the state of Pernambuco was used. The probability density function of the incomplete gamma distribution was used to evaluate the occurrence of dry, regular and rainy years. The monthly climatic water balance was estimated using the Thornthwaite and Mather method (1955), and based on those findings, the climatic classifications were performed using the Thornthwaite (1948) and Thornthwaite and Mather (1955) for each site. The method of Kriging interpolation was used for the spatialization of the results. The study classifications were very sensitive to the local reliefs, to the amount of rainfall, and to the temperatures of the regions resulting in a wide number of climatic types. The climatic classification system of Thornthwaite and Mather (1955) allowed efficient classification of climates and a clearer summary of the information provided. In so doing, it demonstrated its capability to determine agro climatic zones.

[Proteinogram and serum concentrations of copper, iron and zinc in Santa Ines ewes with Staphylococcus aureus experimentally induced mastitis.] Proteinograma e teores de cobre, ferro e zinco no soro sanguineo de ovelhas da raca Santa Ines com mastite experimental por Staphylococcus aureus. Pesquisa Veterinaria Brasileira 30(5):435-442. Clinica de Bovinos, Campus Garanhuns, Universidade Federal Rural de Pernambuco (UFRPE), Avenida Bom Pastor s/n, Boa Vista, Caixa Postal 152, Garanhuns, PE 55292-901, Brazil. E-mail: carlalopes.mendonca@gmail.comThe aim of the present study was to evaluate the effect of Staphylococcus aureus experimentally induced mastitis on proteinogram and serum concentrations of cupper, iron and zinc levels of Santa Ines primiparous ewes. The right mammary gland of ten healthy ewes was inoculated with 1,0x10(4) UFC/mL of S. aureus. Clinical examination and determination of serum concentrations of proteins by electrophoresis in polyacrylamide gel (SDS-PAGE), cupper, iron and zinc, as well plasma level of fibrinogen were measured before the inoculation (control) and 12h, 24h, 36h, 48h, 60h, 72h, 84h, 96h, 108h, 120h, 132h, 168h, 180h, 288h and 336h after bacteria inoculation. All animals experimentally infected presented clinical mastitis and subsequent loss of mammary gland function. The electrophoretogram allowed the identification of 23 proteins with molecular weights (MW) ranged from 26.000 to 185.000 daltons (Da) including acute-phase proteins, IgG and IgA. A significant increase (P<0,05) in haptoglobin, ceruloplasmin, IgG and IgA concentrations was observed. Antitrypsin and acid glicoprotein concentrations did not alter. The levels of iron and zinc decreased and the cupper concentration increased. A positive correlation between plasma fibrinogen and serum ceruloplasmin (r=0.74), haptoglobin (r=0.62) and IgA (r=0.62) was also identified. Results showed the importance of ceruloplasmin and haptoglobin as acute-phase proteins in ewes with intramammary infections and confirms fibrinogen as an inflammatory marker because its high correlation with specific proteins. The alterations in the serum levels of Cu, Fe and Zn suggest the action of inflammatory mediators triggered by S. aureus.

This paper aimed to verify the presence of black-fly of citrus in the state of Pernambuco in Brazil and wordwide. The material with symptoms were collected in the metropolitan area of Recife/PE and subsequently led to the identification in the Insect Biology Laboratory of the Federal Rural University of Pernambuco - UFRPE on February 4, 2011. The samples collected from the branches of citrus and bilocular, found the presence of eggs, nymphs, "pupae" and adults of Aleurocanthus woglumi, confirming its occurrence in the state of Pernambuco. The presence of blackfly of citrus had been detected in the city in the state of Pernambuco as Timbauba, Bom Jardim, Macaparana, Axes, Orobo, Sao Vincent Farrer and Itambe in citrus plants. Before that had a suspect in the Valley Siriji/PE, now it is in the metropolitan area of Recife, therefore we can confirm that the material collected and identified in the metropolitan area of Pernambuco is A. woglumi.
