Dirofilaria immitis é um nematoide de ampla distribuição geográfica, que ocorre com maior frequência em áreas quentes e úmidas do planeta. O primeiro registro de sua ocorrência na América do Sul foi realizado em 1878, no Brasil. Naquela época os registros eram poucos e raramente de fácil obtenção, razão pela qual reuni-los facilitará a recuperação da memória ao longo dos anos. Quatro bases de dados (Scopus, MEDLINE, LILACS e PubMed) foram estudadas utilizando-se as palavras-chave “Dirofilaria” ou “heartworm”, os nomes dos países da América do Sul e o México. Nenhum registro foi encontrado para quatro países (Bolívia, Equador, Guiana Francesa e Uruguai) e para outros três (Suriname, Guiana e Paraguai) os registros eram antigos. Apenas o Chile é o território onde houve estudos registrados com ausência do parasita. Os outros países (México, Peru, Colômbia, Venezuela, Argentina e Brasil) apresentam registros com frequência variável no tempo ou no espaço. Assim, as informações reunidas indicam que infecções por D. immitis ocorrem na maior parte da América do Sul e no México e que os médicos veterinários devem instituir programas preventivos para garantir cuidados médicos de qualidade aos pacientes e para proteger a saúde destes e de suas famílias. | Dirofilaria immitis (Leidy, 1856; Raillet & Henry 1911) is a parasite that is widely disseminated around the globe, with a higher prevalence in warm, humid climates. The first report of its occurrence in South America is from 1878 in Brazil. At that time, reports were scarce and difficult to retrieve – therefore, gathering them will facilitate record-keeping over time. Four databases were searched (Scopus, MEDLINE, LILACS, and PubMed) and the search keywords were “Dirofilaria” or “heartworm” and the countries’ names. Four countries lacked reports (Bolivia, Ecuador, French Guiana, and Uruguay) and other three (Suriname, Guyana, and Paraguay) had only old reports. Chile was the only country in which studies were conducted over time, and no infected dogs were registered. For the other six countries (Mexico, Peru, Colombia, Venezuela, Argentina, and Brazil), reports showed that the infection frequency varied over time and with the surveyed area. Therefore, the information indicates that D. immitis is established, and veterinarians must institute preventive programs to optimally care for their patients and protect the health of their families.

O objetivo deste estudo foi avaliar a influência do fator de crescimento epidermal (EGF) em diferentes momentos da maturação in vitro de oócitos caninos. Os ovários foram coletados de 55 cadelas consideradas sadias e isolados assepticamente, imersos em solução fisiológica e transportados refrigerados. Os complexos cumulus-oócito (COCs) grau 1 foram selecionados e divididos em dois grupos, denominados grupo controle (GC) e grupo tratamento (GT). No GC, 698 COCs grau I foram cultivados em placas de quatro poços contendo meio TCM-199 suplementado com 25 mM de HEPES, 100 UI/mL de penicilina, 100 mg/mL de estreptomicina, 26 mM de bicarbonato de sódio, 1,5 mM de piruvato de sódio, 2,9 mM de lactato de sódio penta hidratado, 0,6 mM de cisteína, 0,03 UI/mL de hCG, 0,5 µg/mL de FSH, 20 µg/mL de estrógeno em estufa úmida a 38ºC, 5% de CO2 nos períodos de 24h, 48 h e 72 h . Já no GT, 547 COCs receberam o mesmo meio de maturação acrescido de 10 ηg/mL do EGF. Modelos de regressão logística foram elaborados para estimar as chances do oócito ser observado nos estágios de maturação nuclear em diferentes tempos de cultivo. Com base nos resultados encontrados, o meio suplementado com EGF demonstrou 2,56 vezes mais chances de ter um oócito no estágio de metáfase I (M-I) do que o meio sem EGF (p < 0,0001). Os resultados desse estudo demonstraram também que o tempo de 72 h mostrou 5,88 vezes mais chances de ter um oócito no estágio de metáfase II (M-II) do que o tempo de 2 h (p = 0,0001) e 7,69 vezes mais chance do que o tempo de 48h (p = 0,0001). As chances de se encontrar um oócito em M-II também foram 9,09 vezes maiores no meio suplementado com EGF do que no meio sem EGF (p = 0,0001). Dessa forma, estes resultados demonstraram a importância essencial do EGF em diferentes momentos da maturação oocitária, sendo componente chave para a aquisição da competência meiótica nas cadelas, aumentando os índices de M-I e M-II. | The aim of this study was to evaluate the influence of epidermal growth factor (EGF) on in vitro maturation of canine oocytes at different times of the process. Ovaries were collected from 55 bitches considered healthy and aseptically isolated, immersed in physiological solution (0.9% NaCl) and transported under refrigeration. Grade 1 cumulus-oocyte complexes (COCs) were selected and divided into two groups: control group (CG) and treatment group (TG). In CG 698 grade I COCs were placed in 4-well plates containing TCM-199 medium supplemented with 25 mM HEPES, 100 IU/mL penicillin, 100 mg/mL streptomycin, 26 mM sodium bicarbonate, 1.5 mM sodium pyruvate, 2.9 mM sodium lactate pentahydrate, 0.6 mM cysteine, 0.03 IU/mL hCG, 0.5 μg/mL FSH, 20 μg/mL estrogen at 38.5ºC in a humidified atmosphere of 5% CO2 in times of 24 h, 48 h, and 72 h. In TG 547 COCs received the same maturation medium plus 10 ηg/mL EGF. Logistic regression models (SAS, 2011) were constructed in order to estimate the chances of oocytes being observed at nuclear maturation stages in different culture times (24 h, 48 h, and 72 h). Based on the results found EGF-supplemented medium showed 2.56 times more chances of having an oocyte at metaphase I (M-I) than medium without EGF (p < 0.0001). The results of this study demonstrated that the time of 72 h showed 5.88 times more chances of having an oocyte at metaphase II (M-II) compared to time of 24 h (p = 0.0001) and 7.69 times more chance than time of 48 h (p = 0.0001). The chances of finding an oocyte at M-II were also 9.09 times higher in medium supplemented with EGF than in medium without EGF (p = 0.0001). Thus, these results demonstrated the essential importance of EGF at different moments of oocyte maturation, being a key component for the acquisition of meiotic competence in bitches, increasing the M-I and M-II rates.

Devido ao aumento do número de cães e gatos domiciliados, a indústria de alimentos para animais de estimação tem expandido a gama de produtos existentes no mercado de pet food. Para obter informações mais relevantes sobre o segmento de alimentos úmidos para cães e gatos, este trabalho determinou a composição nutricional, avaliou as informações declaradas nos rótulos e comparou a composição com as recomendações da Fediaf de proteína e gordura. Também foram comparadas três metodologias diferentes de análise de gordura: extrato etéreo (CFa), extrato etéreo após hidrólise ácida (CFAH) e teor de gordura obtido no analisador Ankom XT15 (ANKOM) para determinar o método mais adequado de avaliação de gordura em alimentos úmidos. Foram avaliadas 25 marcas de alimentos úmidos, 13 para cães e 12 para gatos. As análises de composição centesimal obtidas neste estudo foram comparadas com a informação nutricional declarada nos rótulos e com as necessidades mínimas recomendadas pela Fediaf para cada espécie. Os resultados da composição nutricional, os valores descritos no rótulo e a avaliação dos três métodos para determinação da gordura foram comparados com o emprego do teste t e modelo misto com medidas repetidas nas mesmas amostras, respectivamente (p < 0,05) no programa SAS. Já a avaliação da adequação nutricional de proteína e do teor de gordura foram analisados por cálculos matemáticos de diferença e proporção. Para a maioria dos alimentos avaliados não foi observada diferença entre a composição nutricional dos alimentos úmidos e os valores declarados em rótulo, e houve predominância de produtos que excederam as recomendações mínimas de proteína e gordura da Fediaf para ambas as espécies. Quanto às metodologias de extração de gordura, não foi observada diferença entre os três métodos avaliados (p = 0,68). Concluiu-se que os alimentos úmidos avaliados atendem às informações declaradas pelos fabricantes e também às recomendações nutricionais da Fediaf com base na ingestão energética recomendada. Em relação às metodologias avaliadas para determinação de gordura nestes alimentos, a similaridade entre tais resultados justifica o uso da técnica de maior facilidade ou de menor custo. | As a consequence of the increasing number of dog and cat owners, the pet food industry is expanding the range of pet food products in the market. In order to obtain more necessary information about the wet food segment for dogs and cats, the aim of this study was to determine the nutritional composition, to evaluate the information declared on the labels, and to compare the composition with the FEDIAF recommendations for protein and fat. Furthermore, three different methodologies of fat analysis were compared: crude fat (CFa), crude fat after acid hydrolysis (CFAH), and fat content obtained with Ankom XT15 (ANKOM) to determine the most adequate method for fat determination in wet foods. Twenty-five wet food products were evaluated, 13 wet foods for dogs and 12 for cats. Centesimal composition analyses obtained in this study were compared with guaranteed analysis declared on the label and with FEDIAF minimum recommended requirements for each species. The results of the nutritional composition and the values described on the label and the evaluation of the three fat determination methods were compared using the mixed model test with repeated measurements in the same samples, respectively (p < 0.05) in the SAS program, evaluation of protein adequacy and fat content were analyzed by mathematical calculations of difference and proportion. No difference was observed between nutritional composition of wet foods and the values declared on the labels for the majority of the diets analyzed, and there was a predominance of products that exceeded FEDIAF minimum recommendations of protein and fat for both species. No difference was observed between the three methods of fat content evaluation (p = 0.68). It was concluded that wet foods evaluated in this study match the label information and FEDIAF nutrient requirement recommendations, considering recommended calorie intake. All three fat determination methodologies evaluated were similar, justifying the choice of the easiest or cheapest method.

A cinomose canina é uma das principais doenças infecciosas em cães e animais selvagens, resultando em alta morbidade e mortalidade. O gene H tem uma das maiores variabilidades genéticas entre os genes codificados pelo vírus da cinomose canina (CDV), e tem sido utilizado para caracterizar as estirpes de CDV, permitindo a identificação de linhagens específicas. A variação no gene H pode permitir que o vírus evite o reconhecimento por anticorpos induzidos pela vacina, resultando em falha vacinal. O objetivo deste estudo foi caracterizar o gene H em estirpes de CDV de cães infectados naturalmente no estado de São Paulo. A análise filogenética revelou que as estirpes de CDV brasileiras estão geneticamente relacionadas as estirpes circulantes no Uruguai, na Argentina e na Europa. Não foi encontrada nenhuma evidência da circulação no estado de São Paulo das linhagens América do Sul 2 e 3. O grau de divergência genética entre linhagens selvagens de CDV brasileiras e as estirpes vacinais podem sugerir a possibilidade de falhas vacinais e consequentemente a ocorrência de surtos de cinomose canina. | Canine distemper is one of the major infectious diseases in dogs and wild animals, resulting in high morbidity and mortality. The H gene has the greatest genetic variability among the genes encoded by the canine distemper virus (CDV) genome, and it has been used to characterise field samples, allowing the identification of specific lineages. Variation in the H gene can allow the virus to evade recognition by vaccine-induced antibodies, resulting in vaccine failure. The purpose of this study was to characterise H gene in CDV strains from naturally infected dogs in the state of São Paulo. The phylogenetic analysis revealed that Brazilian CDV strains were genetically related to the circulating CDV strains in Uruguay, Argentina, and Europe. We found no evidence of South America 2 and 3 CDV lineages circulating in Brazilian dogs. The degree of genetic divergence between wild Brazilian CDV strains and vaccine strains may suggest the possibility of vaccine failures and consequently the occurrence of canine distemper outbreaks.

A esporotricose é uma dermatozoonose que tem como agentes etiológicos fungos do gênero Sporothrix. É responsável por quadros micóticos ditos de implantação. Essa micose, de características antropo e saprozoonóticas e cujas principais fontes de infecção são os felinos domésticos, o solo e os vegetais, tem sido responsável por surtos epizoóticos e epidêmicos no sul e sudeste brasileiro. Este relato apresenta o caso de um felino diagnosticado e tratado para esporotricose pelo Serviço de Dermatologia do Hospital Veterinário da FMVZ/USP, após ter sido encaminhado pelo Departamento de Dermatologia da EPM/Unifesp, onde os proprietários do animal estavam sendo tratados para esporotricose humana. | Sporotrichosis is a dermatozoonosis caused by fungi of the Sporothrix genus. It is classified as an implantation mycosis. This fungal infection, with anthropozoonotic and saprozoonotic characteristics and which has domestic felines, soil, and vegetables as main sources of infection, has been responsible for epizootic and epidemic outbreaks in southern and southeastern Brazil. This report presents the case of a feline diagnosed and treated for sporotrichosis at Dermatology Service of FMVZ/USP, after referral from the Dermatology Department of EPM/Unifesp, where the owners of the cat were being treated for human sporotrichosis.

Öz?ensoy, Yusuf | ?ahin, Seyda
Objective: The identification of meat species in meat products is important for protection of human health, economic reasons, religious factors and for controlling the compliance with food regulations. For this purpose, DNA must be obtained in good quality and quantity. The aim of this study was to compare different DNA isolation methods from different meat products.Materials and methods: Comparison among different DNA isolation methods was done. DNA was isolated from different meat products (e.g., sucuk, salami, sausage, braised meet, meatball and pastrami). The methods included phenol/chloroform, DNA isolation kit, Cetyl Trimethyl Ammonium Bromide (CTAB) and Dodecyle Trimethyl Ammonium Bromide (DTAB).Results: Although DNA was obtained from all of these methods, the phenol/chloroform and DNA isolation kit methods were found to be the most effective methods for obtaining high quantity DNA. RNA contamination was determined to be common in DTAB method. High quantity of DNA and RNA contamination in terms of quality was detected in CTAB method. Ruminant specific 16S rRNA primer was used to amplify genomic DNA by polymerase chain reaction and all samples were amplified except for some samples of DTAB.Conclusion: DNA isolation kit, another best method, is recommended due to quality and quantity of DNA for researchers who do not want that phenol/chloroform method have toxic substances. This study is also the first study in which DTAB method is used for DNA extraction from meat products.http://doi.org/10.5455/javar.2016.c175

Objective: Brucellosis is a highly contagious zoonosis with global distribution. The disease remains endemic in many countries including Iran, while its seroprevalence in endemic area is not well documented. We aimed to determine the seroprevalence of brucellosis in sheep and goats in Hamedan province, west of Iran.Material and methods: A total of 3,250 blood samples from 2,550 sheep and 700 goats were collected randomly. All samples were analyzed for the presence of Brucella antibodies using Rose Bengal, Wright standard tube agglutination and 2-mercaptoethanol agglutination tests.Results: The seroprevalence rate of brucellosis in animals and flock level were found in 4.6% and 13.6% of goats and 3% and 27.9% of sheep, respectively. No evidence of correlation between gender and Brucella infection rate were found in animals (P>0.05). Statistical significant differences was seen between age groups and infection rate in goats (P=0.033, OR=2.1); unlike to sheep (P=0.373). Also, the infection rate in nomads population of sheep was higher than fix location animals (P=0.003; OR=1.9); unlike to goats (P=0.195). In animals with history of abortion and vaccination against brucellosis, seroprevalence rate was significantly lower than other (P<0.05).Conclusion: This is the first report of brucellosis in sheep and goats in Hamedan province. The design of a comprehensive control program including vaccination, screening, and culling of brucellosis-positive animals is recommended.http://doi.org/10.5455/javar.2016.c179

Objective: This study was carried out to investigate the effects of estradiol benzoate (EB) injection to male rabbits on glucose, total-protein, albumin, calcium concentrations and prostate tissue, and the role of prolactin as an important mediator of estrogen action in prostate.Materials and methods: Fifty four adult male rabbits were used in this study. The rabbits were randomly divided into two groups. Group A contained 36 male rabbits, which were further randomly divided into four sub-groups, three of them contained 10 rabbits and one sub-group contained 6 rabbits as control. Group B contained 18 male rabbits, which were divided randomly into three equal sub-groups. Three sub-groups of Groups A and B were treated once each on alternative day with the intramuscular injections of EB dosed at 40, 80 and 120 µg/rabbit, respectively for 20 days, whereas the fourth sub-group of Group A received no estradiol, and Group B received 1 mg Bromocriptine Mesilate in addition to EB through oral route on each alternative day. Blood samples were collected for measuring glucose, t-protein, albumin and calcium levels. Prostate tissue samples were collected from all the rabbits for histological studies.Results: Glucose was significantly (P?0.05) increased as a result of 80 µg EB injection, while significantly (P?0.05) decreased due to 40 and 120 µg EB injection. Total protein significantly (P?0.05) increased due to injection of 40 µg EB, however t-protein was not changed due to 40 and 120 µg injection. On the other hand, the results of albumin and calcium were not affected (P?0.05) by EB. In prostate tissues, EB induced hyperplasia with dysplasia or dysplasia only, but this effect was mild due to inhibition of prolactin.Conclusion: The injection of EB to male rabbits increased or decreased glucose level, increased t-protein level mildly or not changed, while albumin and calcium levels were not affected. EB induced hyperplasia on prostate tissue, and this effect was reduced by prolactin inhibition indicating that prolactin might have a role on the action of estrogen.http://doi.org/10.5455/javar.2017.d184

Objective: Molecular based study was conducted to determine the associated serotypes in the reemergence of Foot and Mouth Disease (FMD) outbreak in Assiut governorate, Egypt during 2014 and 2015.Materials and methods: One hundred and twenty cattle with clinical signs suggesting their infection by FMDV were examined clinically and twenty three of them were used for confirmation by laboratory diagnosis. Different clinical samples including vesicular fluid and tongue epitheliums were collected and after RNA extraction using commercial kit, RT-PCR was done using different primer sets.Results: Serotype O was detected in 8 samples, 2 of them were also positive for SAT2 serotype. The determination of specific serotype was failed in case of the rest 13 samples although they were positive when tested by the universal primer specific for FMDV. Conclusion: Serotypes O and SAT2 were the more prevalent serotypes in the current outbreak in Assiut governorate, Egypt.http://doi.org/10.5455/javar.2017.d186

Objective: This study envisages dynamics and factors affecting fecal oocyst counts (FOC) in natural infection in goats in semi-arid India.Materials and methods: A total of 1152 fecal samples from Jamunapari goats in semi-arid India were collected, processed and examined for fecal oocysts over a period of 3 years for prevalence and severity of the disease through FOC using modified Mc Master Technique. The log transformed FOC data on 912 animals from 59 sires were used for subsequent analyses for genetic and non-genetic factors affecting FOC. Fixed effects included were years of collection (1-3), seasons of collection (summer, rainy, winter), sex (male, female), age group (0-3, >3-6, >6-12, adults). Least squares analysis of variance for fitting constant was applied to data set.Results: The overall prevalence of coccidian infection in goats was 86.71%(n=999/1162). Highest incident was found in winter season (91.74%) and >6-12 M age (97.95%). Eimeria arloingi and E. ninakohlyakimovae were the most frequently occurring species. The heritability of FOC was found to be 0.06±0.06. The effect of sire on FOC was not significant; however, effects of animal age, year, season of collection and sex on FOC were found to be significant.Conclusion: Coccidiosis in goats is seasonally occurring disease, most commonly affecting animals of less than one year age. FOC in coccidiosis affected animals is lowly inherited trait for selection of goat against this disease.http://doi.org/10.5455/javar.2017.d190
