An outbreak of systemic intoxication with irritant contact dermatitis due cypermethrin in dairy cows: case report / Surto de intoxicação sistêmica com dermatite de contato irritante devido à cipermetrina em vacas leiteiras: relato de caso

Pyrethroids are ectoparasiticides safe for mammals and widely used in farm animals. An outbreak of systemic intoxication with irritant contact dermatitis resulting from the use of cypermethrin pour on in dairy cows is reported in the state of Pernambuco. Eight adult animals were affected, three died on the property and five were referred to the Clínica de Bovinos, Universidade Federal Rural de Pernambuco, Campus Garanhuns. These received 100 mL of pour on Cypermethrin (Ectonil ®, Cipermetrina, Labgard, Brasil). Apathy, hyperexcitability, muscle tremors, sialorrhea, bradycardia and crusted lesions were observed on the dorsum of the neck, scapula, ears and ulcerations in the oral and vaginal mucosa. There was hyperfibrinogenemia and leukocytosis due to neutrophilia with a regenerative left shift. Histopathology showed areas of erosion and ulceration of the epidermis and perivascular lymphohistiocytic and neutrophilic infiltrate in the superficial dermis. Supportive treatment was done with improvement of systemic signs and skin lesions, however, in one animal (with 19 days hospitalized), there was no complete regression of neurological alterations of bradycardia and muscle tremors, even so, it was possible to return to productive activity. High doses of pour on cypermethrin may cause systemic intoxication in cattle and result in bradycardia, hyperexcitability, muscle tremors and sialorrhea with irritant contact dermatitis, and death in severe cases.

Os piretroides são ectoparasiticidas com grande segurança para mamíferos, utilizados amplamente em animais de produção. Relata-se um surto de intoxicação sistêmica com dermatite irritante por contato, resultante do uso de Cipermetrina Pour-On em bovinos, no estado de Pernambuco. Oito animais adultos foram acometidos: três deles morreram na propriedade e cinco foram recebidos na Clínica de Bovinos da Universidade Federal Rural de Pernambuco, Campus Garanhuns. Todos haviam recebido 100mL de Cipermetrina Pour-On (Ectonil®, Cipermetrina, Labgard, Brasil). Observou-se apatia, hiperexcitabilidade, tremores musculares, sialorreia, bradicardia e lesões crostosas no dorso da região de pescoço, na escápula, mas orelhas, bem como ulcerações em mucosa oral e vaginal. No hemograma, verificou-se hiperfibrinogenemia e leucocitose por neutrofilia com desvio à esquerda regenerativo. Na histopatologia, foram constatadas áreas de erosão e ulceração da epiderme e infiltrado linfo-histiocitário e neutrofílico perivascular na derme superficial. O tratamento de suporte gerou melhora dos sinais sistêmicos e das lesões cutâneas, porém, em um dos animais (que esteve internado por 19 dias), não houve regressão completa das alterações neurológicas de bradicardia e de tremores musculares; mesmo assim, foi possível o retorno à atividade produtiva. Doses elevadas de Cipermetrina Pour-On podem causar intoxicação sistêmica em bovinos e resultarem em bradicardia, hiperexcitabilidade, tremores musculares e sialorreia com dermatite irritante por contato, bem como morte em casos severos.

Parasitism of a capybara (Hydrochoerus hydrochaeris) by Amblyomma nodosum Neumann, 1899 and Amblyomma humerale Koch, 1844 in an Amazon forest area, Rondônia, Brazil / [Parasitismo por Amblyomma nodosum Neumann, 1899 e Amblyomma humerale Koch, 1844 em capivara (Hydrochoerus hydrochaeris) em área de Floresta Amazônica, Rondônia, Brasil]

Dois carrapatos adultos, sendo um Amblyomma nodosum e um Amblyomma humerale foram encontrados parasitando ativamente uma capivara (Hydrochoerus hydrochaeris) proveniente da região central do estado de Rondônia, Brasil, na zona rural do município de Ji-Paraná, localizado na Amazônia ocidental. Poucos trabalhos científicos relatam a presença de A. humerale em capivaras. Assim, esta é a primeira vez que A. nodosum é relatado parasitando essa espécie animal. Por não se tratar de um hospedeiro animal conhecido para A. nodosum ou comum para A. humerale, esses achados podem sugerir uma nova relação entre hospedeiros para eles. Portanto, são necessários mais estudos acerca da ecologia desses parasitas, principalmente por serem potenciais transmissores de patógenos de importância em medicina veterinária e saúde pública.(AU)

FSH and LH enhance the development of goat preantral follicles cultured in vitro

This study evaluated th e effect of increased follicle stimulating hormone (FSH) concentrations on the expression of mRNA for LH receptors after in vitro culture of goat preantral follicles ( ≥ 150 μm) for 18 days. It also investigated whether the addition of luteinizing hormone (LH) to the culture medium, which contained increasing concentrations of FSH throughout the culture period, influenced the surv ival, growth and antrum formation of in vitro cultured goat preantral follicles. In experiment 1, preantral follicles were cultured in α -MEM + or α -MEM + supplemented with increasing concentrations of FSH throughout the culture period (sequential medium: FSH 100 ng/ml (days 0 to 6), FSH 500 ng/ml (days 6 to 12) and FSH 1000 ng/ml (days 12 to 18). The expression of luteinizing hormone receptor (LHR) was analyzed in noncultured and cultured follicles using real time RT-PCR. In experiment 2, isolated preantral follicles were cultured for 18 days in a sequential medium containing FSH (control) or a control medium supplemented with LH (50 or 100 ng/ml) from day 12 of culture onwards. Follicle development was evaluated on the basis of antr al cavity formation as well as follicular and oocyte growth after in vitro maturation. FSH stimulated a significant increase in the expression of mRNA for LH receptors after 18 days of culture. Furthermore, after 18 days, all tested media promoted follicular survival and antrum formation; however, a significant increase in the rate of follicular growth and resumption of meiosis was ob served when LH was used compared to the control. In conclusion, preantral follicles cultured in a medium supplemented with FSH increased LH receptor mR NA levels. Moreover, the addition of LH to the culture medium containing increasing concentrations of FSH (sequential medium) improved the in vitro development of goat preantral follicles.

Suscetibilidade a antimicrobianos e produção de betalactamase em amostras de Staphylococcus isolados de mastite caprina no semiárido paraibano / Susceptibility to antimicrobial drugs and production of beta-lactamase by Staphylococcus strains isolated from mastitis in goats in the semi-arid region of Paraiba state, Brazil

Este trabalho teve como objetivo avaliar a susceptibilidade antimicrobiana in vitro e a produção de betalactamase de 42 amostras de Staphylococcus isolados de mastite subclínica caprina. Foram utilizados 14 Staphylococcus chromogenes, 10 S. waneri, 6 S. saprophyticus, 5 S. aureus, 3 S. epidermidis, 2 S. intermedius e 2 Staphylococcus coagulase negativo. Os maiores índices de resistência foram para penicilina 66,67% e ampicilina 63,89% e sensibilidade frente a cefoxitina 97,62%. A múltipla resistência a 3 ou mais antimicrobianos foi observada em 42,86% dos isolados. Das 42 amostras de Staphylococcus avaliadas, 73,81% foram positivas para o teste de produção de betalactamase. A concentração inibitória mínima apresentou 100% das amostras susceptíveis à norfloxacina e os valores de resistência para os demais antimicrobianos não ultrapassaram os 30%. A alta resistência apresentada para penicilina e ampicilina demonstra a limitação no uso desses antimicrobianos no tratamento da mastite caprina na região. Embora neste estudo as cefalosporinas tenham apresentado boa sensibilidade, o uso desses fármacos em medicina veterinária se torna preocupante devido à incidência de estirpes produtoras de betalactamase.

The present study was aimed to test the in vitro antimicrobial susceptibility using disc diffusion assay and minimum inhibitory concentration (MIC) values, as well as the production of beta-lactamase of 42 strains of Staphylococcus sp. isolated from subclinical mastitis in goats in the semi-arid region of Paraiba state, in Brazil. To this end, 14 samples of negative Staphylococcus chromogenes, 10 S. waneri, 6 S. saprophyticus, 5 S. aureus, 3 S. epidermidis, 2 S. intermedius and 2 Staphylococcus were used. Regarding the in vitro susceptibility, the highest levels of resistance observed concerned penicillin (66.67%) and ampicillin (63.89%), and the greatest sensitivity observed concerned Cefoxitin (97.22%). Multiple resistance to 3 or more antimicrobial drugs was observed in 42.86% of the isolates. Of the total Staphylococcus isolated, 73.81% were positive for the beta-lactamase production test. The minimum inhibitory concentration showed 100% of the samples susceptible to norfloxacin, and the maximum resistance values to the other antimicrobial drugs were 30%. According to the results obtained, it is concluded that, in order to select the most appropriate drug to treat mastitis in goats caused by strains of Staphylococcus, the antimicrobial sensitivity profile of the strain must be known and routine laboratory tests for detecting beta-lactamase should be performed because these enzymes are disseminated both in human and veterinary medicine. The high resistance to penicillin and ampicillin demonstrates the limitation in the use of antibiotics in the treatment of mastitis in goats. Although in the present study the cephalosporines demonstrated a considerable degree of sensitivity, the use of these antimicrobial agents in veterinary medicine becomes a matter of concern due to the incidence of strains that produce betalactamase.

Ascorbic acid improve the survival and in vitro growth of isolated caprine preantral follicles

The present study aims to investigate the influence of two concentrations of ascorbic acid on the survival, growth , antral formation and m RNA expression of the matrix metalloproteinases - 9 (MMP - 9) and their tissue inhibitor - 2 (TIMP - 2) on caprine preantral follicles during long - term in vitro culture. Isolated preantral follicles were individ ually cultured without or with ascorbic acid at 50 μ g/ml (AA50) or 100 μ g/ml (AA100) during 18 days. The parameters evaluated were follicular viability, growth, antrum formation and extruded oocytes. The genes MMP - 9 and TIMP - 2 were quantified by real - time polymer ase chain reaction (qPCR) after 18 days of culture in the control medium (MEM + ) or ascorbic acid (50 or 100 μ g/ml) and in fresh control (non cultured) . At the end of culture, AA50 significantly increased the percentage of viable follicles compared w ith other treatments . Moreover, mean daily increase in follicular diameter (μm/day) was significantly higher in the presence of both concentrations of ascorbic acid than in MEM + alone. Higher rates of antral formation and lower percentages of extruded oocy tes were observed in medium containing AA50 compared with control medium. Real Time RT - PCR assays showed that AA50 increase s MMP - 9 expression significantly compared with fresh control and MEM + alone. In conclusion, ascorbic acid at 50 μ g/ml was very import ant for the maintenance of caprine preantral follicle viability and development after in vitro culture and influences in vitro the enzymes involved with basement membrane remodeling.

Expression of protein and mRNA encoding Insulin Growth Factor-I (IGF-I) in goat ovarian follicles and the influence of IGF-I on in vitro development and survival of caprine preantral follicles

The aim of this study was to investigate the protein and mRNA expression levels of IGF-I and the effects of IGF-I on preantral follicle survival and development, using an in vitro goat ovarian cortical culture system. The ovaries were used for immunohistochemical localization of IGF-I protein or used to demonstrate mRNA expression of IGF-I. For the latter goal, preantral and antral follicles, cumulus-oocyte complex, mural granulosa and theca cells were collected to study mRNA expression. For in vitro studies, ovarian cortex were cultured for 1 and 7 days with MEM supplemented IGF-I (0, 1, 10, 50, 100 or 200 ng/ml). Immunohistochemical results showed strong reactions for IGF-I in oocytes and granulosa cells of all follicular stages, except in granulosa cells of primordial and primary follicles. mRNA expression analysis demonstrated a discrete increase in the production of IGF-I during the transition from primordial to the primary and secondary follicle stages. After 7 days of culture, addition of 50 ng/ml of IGF-I to the medium showed the greatest percentage of normal follicles when compared with other concentrations. Furthermore, the highest percentage of primary follicles was observed after 7 days of culture in MEM+ plus 10 and 50 ng/ml of IGF-I. Culture of ovarian tissue for 7 days in MEM+ plus 50 ng/ml of IGF-I promoted the greatest increase (P < 0.05) in follicular diameter of all of the concentrations tested. In conclusion, IGF-I protein and mRNA were expressed in all follicular categories of goat. Furthermore, IGF-I maintained preantral follicle survival, promoted primordial follicle activation and stimulated the transition from intermediate to primary follicles.(AU)

Papel do Hormônio Folículo Estimulante na foliculogênese in vivo e in vitro / Role of Follicle Stimulating Hormone in folliculogenesis in vivo and in vitro

A foliculogênese é controlada por diversos hormônios e fatores de crescimento, que sinergicamente agem regulando os eventos envolvidos na fisiologia da reprodução. Dentre esses hormônios, destaca-se o Hormônio Folículo Estimulante (FSH), que é uma gonadotrofina presente em todas as fases da foliculogênese, atuando de forma direta ou indireta para promover o desenvolvimento folicular in vivo e in vitro. Nesse contexto, a revisão irá abordar o papel do FSH na regulação da foliculogênese de mamíferos, bem como a influência das diferentes origens de FSH sobre o crescimento folicular in vivo e in vitro e o seu papel na reprodução assistida.(AU)

The foliculogenesis is controlled by various hormones and growth factors, which act synergistically to regulate the events involved in the physiology of reproduction. Among these hormones, the Follicle Stimulating Hormone (FSH) is a gonadotropin which is present in all stages of folliculogenesis, acting directly or indirectly to promote the follicular development in vivo and in vitro. In this context, the review will contribute to a better understanding of the role of FSH in the regulation of folliculogenesis of mammals as well as the influence of different sources of FSH on the follicular growth in vivo and in vitro and its role in assisted reproduction.(AU)

Efeito do consumo de óleo de linhaça e de vitamina E no desempenho e nas características de carcaças de frangos de corte / Effect of linseed oil and vitamin E consumption on poultry performance and carcass traits

Foi avaliado o efeito da utilização de óleo de linhaça na ração, em substituição ao óleo de soja em diferentes proporções, e de vitamina E, até o nível de 400mg/kg de ração, sobre o desempenho e a composição de carcaça de frangos de corte. O desempenho produtivo foi avaliado com base em pesagens das aves e da ração aos 21 e 49 dias de idade. No 49º dia, as aves foram abatidas, e os rendimentos de carcaça e dos principais cortes comerciais e a porcentagem de vísceras e de gordura abdominal foram avaliados. A composição da fração oleosa da ração, de forma geral, não interferiu nos parâmetros de desempenho avaliados (P>0,05). Os machos consumiram mais ração e ganharam mais peso que as fêmeas (P<0,01). As fêmeas apresentaram, em geral, pior conversão alimentar, associada à maior deposição de gordura abdominal. Os machos apresentaram maior porcentagem de coxa com sobrecoxa em relação ao peso da carcaça eviscerada, e as fêmeas apresentaram maior porcentagem de peito. A porcentagem de asas e vísceras não diferiu entre os sexos.(AU)

The effect of the utilization of linseed oil at different concentrations in poultry feed instead of soy oil and the effect of vitamin E administration up to 400mg/kg feed on performance and carcass traits of broilers was investigated. Productive parameters were determined by weighting birds and rations at 21 and 49 days of experiment. Broilers were slaughtered on the 49th day of the experiment for the evaluation of yields of carcass and main cuts, percentages of viscera and abdominal fat. The oil composition of rations did not influence the performance of the broilers (P>0.05). Male broilers had higher feed consumption and weight gain (P<0.05). Female broilers showed worse feed conversion and higher deposition of abdominal fat (P<0.05). Male broilers also had higher percentages of legs and forelegs in relation the weight of the eviscerated carcass while females showed higher breast percentage (P<0.05). Percentages of wings and viscera did not differ between genders (P>0.05).(AU)

PLANEJAMENTO DAS AÇÕES DE MANEJO POPULACIONAL DE CÃES E GATOS NO MUNICÍPIO DE LENÇÓIS PAULISTA, SÃO PAULO

O planejamento e execução de ações de manejo das populações de cães e gatos em áreas urbanas é um grande desafio para os gestores da saúde, pela falta de diagnóstico situacional relacionado à realidade da população destes animais no território urbano do município. São indicados três métodos para o controle populacional de cães e gatos: restrição da movimentação, controle do habitat e controle reprodutivo. As ações de educação permanente em saúde para a posse responsável de animais de estimação e a esterilização cirúrgica de cães e gatos são medidas indicadas como estratégias de controle populacional para essas espécies. Com base nestas afirmações, o objetivo do presente trabalho foi realizar um diagnóstico situacional do aspecto de castração dos animais levados aos postos de vacinação contra a Raiva, em 2013, na 18ª Campanha de vacinação anual contra a Raiva de cães e gatos de Lençóis Paulista/SP. Os dados foram obtidos a partir da ficha de cadastro de animais que foi utilizada na campanha de 2013, que continham campos para preenchimento de informações relacionadas à castração e à localização do proprietário. Com base nesses dados realizou-se a análise descritiva bem como a distribuição espacial dos resultados. O software ArcGIS 10.1® foi utilizado para elaboração dos mapas. Os resultados revelaram que a população de animais castrados representa apenas 7,14% do total de animais
