This study aimed to study the effect of antibiotic on phospholipase production of Staphylococcus aureus isolated from preputium of Aceh cattle. The parameters measured in this study were PzI of Staphylococcus aureus without any treatment, and PzI of S. aureus after being given antibiotics. The experiment was carried out by modifying the Samaranayake method on egg yolk agar media, incubated at 37 ° C for 48 hours, and the precipitation lines formed was measured. The antibiotics used were tetracycline, oxytetracycline and fosfomycin with concentrations of 10%, 20% and 30% (mg / mL, respectively). The results showed that phospholipase production of S. aureus isolated from preputium of Aceh cattle was suppressed, antibiotics were able to inhibit phospholipase production. However, the enzyme was still produced in positive category, with PzI = 0.287, the highest result was found in 30% tetracycline activity, which is equal to PzI = 0.341 and the lowest was in 10% fosfomycin which is equal to PzI = 0.332

The present study evaluated Brangus cows treated with single doses of follicle stimulating hormone (FSH) subjected to follicular aspiration after 24 h to assess oocyte recovery, in vitro fertilization and pregnancy rate. Follicles exceeding 3 millimeters in diameter were aspirated, 200 mg of FSH was administered 2 days later, and a new ovum pickup was performed 24 h afterward. These methods were performed 3 times every 3 days. In control, follicular aspirations occurred at intervals of 1-week without FSH administration o. The aspirated oocytes were evaluated, submitted to in vitro fertilization and the embryos were transferred to the recipients. The average recovery of oocytes was higher (p<0.05) in control cows (12.4±1.8) than in treated cows (9.4±1.3). There was no difference (p>0.05) in the mean percentage of viable oocytes (52.0±3.9 and 62.7±4.7%) or the mean percentage of embryos (41.4±4.8 and 41.5±4.2%) among control and treated cows, respectively. The mean percentage of pregnancy did not differ (p>0.05) for control cows (43.8±2.7%), and treated cows (40.9±6.8%). In conclusion, FSH treatment did not improve oocyte recovery, in vitro fertilization, and pregnancy percentage. However, there is possibility of several consecutive ovum pickup every t3 days, concentrating the in vitro fertilization and the pregnancy percentage.

O presente estudo avaliou vacas Brangus tratadas com doses únicas de hormônio folículo estimulante (FSH) submetidas a aspiração folicular após vinte e quatro horas, para avaliação da recuperação oocitária, fertilização in vitro e taxa de prenhez. Folículos superiores a três milímetros de diâmetro foram aspirados, 200 mg de FSH foram administrados dois dias depois e uma nova aspiração folicular foi realizada 24 horas após. Esses métodos foram efetivados três vezes a cada três dias. No controle, as aspirações foliculares ocorreram em intervalos de uma semana sem administração de FSH. Os&nbsp;oócitos aspirados foram avaliados, submetidos à fertilização in vitro e os embriões foram transferidos em receptoras. A recuperação média dos oócitos foi superior (p&lt;0,05) nas vacas controle (12,4±1,8) do que nas vacas tratadas (9,4±1,3). Não houve diferença (p&gt;0,05) na porcentagem média de oócitos viáveis (52,0±3,9 e 62,7±4,7%) ou na porcentagem média de embriões (41,4±4,8 e 41,5±4,2%) entre vacas controle e vacas tratadas, respectivamente. A porcentagem média de prenhez não diferiu (p&gt;0,05) para as vacas controle (43,8±2,7%) e as tratadas (40,9±6,8%). Em conclusão, o tratamento com FSH não melhorou a recuperação de oócitos, a fertilização in vitro e o percentual de prenhez. No entanto, existe a possibilidade de várias aspirações foliculares consecutivas a cada três dias, concentrando a fertilização in vitro e o percentual de prenhez. | The present study evaluated Brangus cows treated with single doses of follicle stimulating hormone (FSH) subjected to follicular aspiration after 24 h to assess oocyte recovery, in vitro fertilization and pregnancy rate.

Tick infestation causes major problems in cattle. Tick parasitism accounts for significant economic losses in many beef and dairy herds in the vast majority of the states in the Brazilian territory including the State of Santa Catarina in the southern region of the country. Tick resistance to several active principles occurs due to a number of factors including the indiscriminate, injudicious and inadequate use of tick insecticides. Considering the great importance of fighting off tick infestations in cattle, we evaluated the efficiency of 8 different topical active principles against the ixodid tick R. microplus and identified the main factors that contribute to the development of ticks that are resistant to acaricides in the farms and bovine herds studied. For such purpose, R. microplus telegionae were collected in 39 farms locates in different municipalities of the West of Santa Catarina, south Brazil. At the time of sample collection, information about the management, the history of the acar used in the herd, the number of annual applications of these pesticides, the frequency of acaricide rotation, and the frequency of technical monitoring for strategic tick control were retrieved. We collected this data in order determine contributing factors to the development resistant R. microplus populations. For the sensitivity profile of these ticks to a number of different acaricides tested, 10 engorged females for each principle and a control were used. The results of our study show that most associations between pyrethroids and organophosphates had an efficiency between 96.6% and 100% in the control of R. microplus except for the combination of Alfacipermetrine 15%, Ethion 16%, and Chlorpyrifos 8.5% that had 93.4% of efficiency. Among the chemicals not associated with any other type of compound, Amitraz 12.5% ​​was effective in 98.3% of the cases. In contrast, Cypermethrin 15% had an efficiency in only 25.8% of the farms/herds analyzed. Based on the results of the present study, we may infer that the methods of control and management used by producers may be related to the low indexes of resistance to topical acaricides in the different populations of ticks in the study area.

A infestação por carrapatos em bovinos gera grandes problemas, sendo esse parasito responsável por elevados prejuízos econômicos em diversos rebanhos de produção de corte e também de leite na maioria das regiões brasileiras, inclusive em Santa Catarina. A resistência dos carrapatos frente aos diversos princípios ativos pode ser decorrente de fatores como o uso indiscriminado de carrapaticidas, bem como a inadequada forma de aplicação dos mesmos. Tendo em vista a grande importância em combater essas infestações, buscou-se avaliar a eficiência de oito diferentes princípios ativos de contato contra o carrapato Rhipicephalus microplus, bem como identificar os principais fatores que possam contribuir com a seleção de carrapatos resistentes nas propriedades avaliadas. Para isso, teleóginas de R. microplus foram coletadas em 39 propriedades de diferentes municípios do Oeste de Santa Catarina. No momento da coleta também foram obtidas informações referentes ao sistema de manejo dos animais, histórico dos carrapaticidas utilizados, número de aplicações anuais, frequência de rodízios de acaricidas, e frequência de acompanhamento técnico para controle estratégico, com a finalidade de evidenciar os diferentes fatores que possam estar contribuindo para o surgimento de eventual resistência das populações do R. microplus. A avaliação de suscetibilidade foi realizada através da técnica de biocarrapaticidograma, utilizando 10 teleóginas ingurgitadas para cada princípio e mais o controle. Dentre os principais resultados obtidos, a maioria das associações entre piretróides e organofosforados demonstraram ter eficiência entre 96,6% e 100%, com exceção da associação de Alfacipermetrina 15%, Ethion 16% e Clorpirifós 8,5% com 93,4% de eficiência. Dentre as bases químicas sem nenhum tipo de associação o Amitraz 12,5% demonstrou ser eficaz em 98,3%, em contrapartida a Cipermetrina 15% teve eficiência em apenas 25,8% das propriedades analisadas. A partir dos resultados obtidos, pode se afirmar que as formas de controle e manejo adotados pelos produtores podem estar relacionadas com os baixos índices de resistência aos carrapaticidas de contato, nas diferentes populações de carrapato na região do estudo. | Tick infestation causes major problems in cattle.

Lymphoma is a very common lymphoid malignancy in dogs, but cardiac involvement is rare. Primary cardiac lymphoma is defined as lymphoma involving the heart, the pericardium, or both, and is classified as extranodal anatomical form. The present report describes the cases of three animals with cardiac lymphoma. All cases presented moderate to severe pericardial effusion and cardiac tamponade. The cytological analysis of the effusion was consistent with the diagnosis of cardiac lymphoma. The anatomopathological evaluation of the tumor extracted from the heart of one of the animals, after euthanasia, was consistent with cardiac lymphoma. The other two animals were treated with Madison-Wisconsin chemotherapy protocol and survived between 6 to 8 months. This report emphasizes the importance of pericardial effusion cytology for the diagnosis, appropriate treatment approach and monitoring of cardiac tumors in dogs and cats.

The objective of this study was to evaluate the in vivo predatory viability of the nematophagous fungus, Duddingtonia flagrans, after storage (36 months) and refrigeration (2-8 °C). This viability was evaluated using the infective larvae of gastrointestinal nematodes of sheep in the Northeastern semi-arid region of Brazil. Sixteen Santa Inês sheep with negative counting of eggs per gram of feces (EPG) were divided into four experimental groups, each group comprised of four animals. The pellets were administered at the dose of 3 g/10 kg of live weight (20% fungal micelyum), and a single administration was performed for each animal. Group I was administered pellets that had been stored for 36 months; Group II, freshly produced pellets; Group III, freshly produced pellets that did not contain fungi; and Group IV, pellets were not administered, and this was the control group. Feces were collected for 5 days, every 24 h for analysis. There was a significant decrease in the number of infective larvae of sheep nematodes that received D. flagrans pellets in a sodium alginate matrix, 82% was observed for Group I and 71% for Group II, compared to the control group. It is therefore concluded that the fungus, D. flagrans, pelleted in sodium alginate matrix after 36 months of storage at 2-8 °C, showed efficacy in reducing the number of infective larvae of gastrointestinal nematodes of sheep.

The presence of lactic acid bacteria (LAB) and histamine in foodstuffs indicate the level of deterioration in the quality of food and cause poisoning. Sie Balu is the Acehnese dried meat preserved by the addition of salt, acid and dried, but the long processing and drying it under the sun can cause microbial contamination in meat products. Irradiation can eliminate bacteria in foodstuffs. This study aimed to determine the amount of LAB and histamine levels of Sie Balu after irradiation doses of 5, 7 and 9 kGy and stored 2 to 4 months. Sie Balu was made of fresh beef 5 kg, dried in the sun to dry, vacuumed and irradiated with gamma rays. The samples for LAB determination cultured in MRS agar and incubated at 37°C for 24 hours. The number of colonies was counted using Total Plate Count. The histamine level of Sie Balu conducted by ELISA. Irradiation did not significantly (P0.05) affect the amount of LAB, but the shelf life significantly (P0.05) affected the amount of LAB in Sie Balu. Extending the shelf life up to 4 months can increase the amount of LAB. Irradiation dose and shelf life had no effect on histamine levels of Sie Balu (P0.05). This study concluded that irradiated Sie Balu cannot be stored for more than two months.

Brazilian spotted fever is a serious and lethal illness for humans and is caused by the Rickettsia rickettsii bacteria. In the state of São Paulo/SP (Brazil), the etiological agent of this disease is transmitted by the Amblyomma sculptum tick. It was already shown that horses infected with this bacteria produce a strong immune response and could be important sentinels for the detection of the disease in a proper region. The present investigation performed a serological survey in horses from five farms of Vale do Paraíba, São Paulo state, Brazil, searching for antibodies against, Rickettsia rickettsii, Rickettsia parkeri, Rickettsia amblyommatis, Rickettsia rhipicephali, and Rickettsia bellii. In each farm, ticks were also collected that were taxonomically identified and examined by real-time PCR for Rickettsia spp DNA. Blood samples were collected from 206 horses, and 334 ticks were picked up from these animals from January to December 2017. Eighty ticks were A. sculptum and 254 Dermacentor nitens. Of the blood samples, 7.3% seroconverted to Rickettsia spp. Of these, 0.97% had a positive serological response to R. bellii. None of the 80 A. sculptum ticks were positive through real-time PCR for Rickettsia spp. Although there was no detection of ticks infected by Rickettsia spp in five farms of Paraíba Valley, the horses presented serological positive reactions against this agent. Thus, further large studies should be conducted in the area targeting hosts and vectors to generate data for control measures of the transmission of Brazilian spotted fever.

A febre maculosa brasileira é uma doença grave e letal para seres humanos causada pela bactéria Rickettsia rickettsii.&nbsp;No estado de São Paulo, SP, Brasil, o agente etiológico desta enfermidade é transmitido pelo carrapato Amblyomma&nbsp;sculptum. Conforme descrito na literatura científica, os cavalos infectados com esta bactéria produzem uma forte resposta&nbsp;imune e podem ser importantes sentinelas para a detecção da doença. A presente investigação realizou um levantamento&nbsp;sorológico em cavalos de cinco fazendas do Vale do Paraíba, São Paulo, Brasil, à procura de anticorpos contra Rickettsia&nbsp;rickettsii, Rickettsia parkeri, Rickettsia amblyommatis, Rickettsia rhipicephali e Rickettsia bellii. Em cada fazenda, também&nbsp;foram coletados carrapatos identificados taxonomicamente e examinados por PCR em tempo real para o DNA de&nbsp;Rickettsia spp. Foram coletadas amostras de sangue de 206 cavalos e coletados 334 carrapatos desses animais entre os meses de janeiro e dezembro de 2017. Oitenta carrapatos foram identificados como A. sculptum e 254 Dermacentor nitens.&nbsp;Das amostras de sangue, 7,3% soroconverteram para Rickettsia spp., sendo que, 0,97% apresentaram soropositividade&nbsp;homóloga para R. bellii. Nenhum dos 80 carrapatos de A. sculptum foi positivo com o emprego de PCR em tempo real&nbsp;para Rickettsia spp. Embora não tenham sido detectados carrapatos infectados por Rickettsia spp em cinco fazendas&nbsp;do Vale do Paraíba, os animais apresentaram reações sorológicas positivas para este agente. Assim, outros estudos&nbsp;abrangentes deverão ser realizados na área investigando hospedeiros e vetores, gerando dados para medidas de controle&nbsp;da transmissão da febre maculosa brasileira. | Brazilian spotted fever is a serious and lethal illness for humans and is caused by the Rickettsia rickettsii bacteria. In the&nbsp;state of São Paulo/SP (Brazil), the etiological agent of this disease is transmitted by the Amblyomma sculptum tick. It was&nbsp;already shown that horses infected with this bacteria produce a strong immune response and could be important sentinels&nbsp;for the detection of the disease in a proper region. The present investigation performed a serological survey in horses&nbsp;from five farms of Vale do Paraíba, São Paulo state, Brazil, searching for antibodies against, Rickettsia rickettsii, Rickettsia&nbsp;parkeri, Rickettsia amblyommatis, Rickettsia rhipicephali, and Rickettsia bellii. In each farm, ticks were also collected that&nbsp;were taxonomically identified and examined by real-time PCR for Rickettsia spp DNA. Blood samples were collected&nbsp;from 206 horses, and 334 ticks were picked up from these animals from January to December 2017. Eighty ticks wereA. sculptum and 254 Dermacentor nitens. Of the blood samples, 7.3% seroconverted to Rickettsia spp. Of these, 0.97%&nbsp;had a positive serological response to R. bellii. None of the 80 A. sculptum ticks were positive through real-time PCR&nbsp;for Rickettsia spp. Although there was no detection of ticks infected by Rickettsia spp in five farms of Paraíba Valley, the&nbsp;horses presented serological positive reactions against this agent. Thus, further large studies should be conducted in&nbsp;the area targeting hosts and vectors to generate data for control measures of the transmission of Brazilian spotted fever.&nbsp;
