RESUMO.Com o objetivo de determinar a frequência de endoparasitos em cães e gatos, foi realizado um levantamento dos resultados de exames coproparasitológicos, executados na rotina de um Laboratório Veterinário em São Luís -Maranhão, no período de julho de 2012 a julho de 2015. Nesse período foram realizados 780 exames, sendo 92% de cães e 8% de gatos. Deste total, 23% das amostras foram positivas para pelo menos um parasito. Ancylostoma sp. foi o gênero mais frequente em ambas as espécies com 48% dos cães e 63% dos gatos parasitados. Quanto à infecção, 80% dos cães e 86% dos gatos apresentaram infecção única, enquanto que 20% dos cães e 14% dos gatos apresentaram infecção múltipla. Esses resultados revelam uma incidência expressiva, o que representa elevados riscos não só aos animais como também na saúde humana e tal fato reforça a necessidade de implementar medidas efetivas no sentido de reduzir a carga parasitária dos animais e minimizar os riscos de infecção humana.

In order to determine the frequency of endoparasites in dogs and cats, a survey was conducted of the results of parasitological tests, performed in the routine of a Veterinary Laboratory in São Luís -MA, from July 2012 to July 2015. In this period they were conducted 780 tests, 92% of dogs and cats 8%. Of this total, 23% of the samples were positive for at least one parasite. Ancylostoma sp. it was the most common genre in both species with 48% of dogs and 63% of infected cats. Regarding infection, 80% of dogs and 86% of cats showed only infected, while 20% of dogs and 14% of cats showed multiple infections. These results reveal a significant impact, which is a high risk not only to animals but also on human health and this fact reinforces the need to implement effective measures to reduce the parasite load of animals and minimize the risk of human infection.

Peccaries are characterized by a prominent skin gland, known as scent gland, which is located in the middle of the rump. These animals are able to survive in a great variety of habitats, from humid tropical forests to semi-arid areas. They are omnivorous animals, and their diet includes fibrous material, vegetables, fruits, small vertebrates and insects. Collared peccary hard palate and soft palate tonsils were studied, macroscopic morphometric data were collected and tissue samples were paraffin-embedded. Sections were stained with HE, Gomori's trichrome and von Kossa; the first two were used to study general organization and the latter to detect calcium deposits. The hard palate showed one incisive papilla followed by several rugae united by a distinct raphe. The hard palate is lined by a keratinised squamous epithelium resting on a dense connective, whereas in the soft palate, the epithelium is parakeratinised and showed lymphocyte infiltration. The palate showed several pacinian corpuscles in the propria-submucosa. Two ovoid-shaped tonsils were found in the soft palate, and several crypts were observed on its surface. The epithelium was highly infiltrated by lymphocytes, and within the crypts, tonsilloliths were frequently observed. The study showed that the general organization of collared peccary palate is similar to other species, but in its oropharynx, only the soft palate tonsil was present and the pacinian corpuscles formed small aggregates.

Objetivou-se avaliar a carga parasitária da cama de frango de uma granja avícola localizada no município de Paço do Lumiar-MA. Foram coletadas 50 amostras de cama de frango de 10 galpões. Essa cama já havia sido utilizada seis vezes nos lotes anteriores. Para as análises parasitológicas foram utilizados os métodos de Sedimentação Espontânea, Método de Sheather, Esporulação para diagnóstico de oocistos de coccídios. Foram identificados ovos de nematódeos dos gêneros Strongyloides (72%), Heterakis (18%) e Ascaridia (10%). As larvas as do gênero Strongyloides destacaram-se como as mais prevalentes, com frequência de 97% de casos, seguido geohelmintos (3%). Encontrou-se 1200 oocistos de Eimeria, no estágio de esporulação. Foram encontrados também ácaros e cascudinhos (Alphitobius diaperinus). Conclui-se que a alta frequência de parasitos presentes na cama de frango pode estar relacionada à falha de manejo.

The diversity of neoplasms observed in dogs can vary geographically depending on individual susceptibility, the habitat of the animals, and environmental characteristics. The aim of this study was to evaluate the epidemiological aspects of neoplasms in dogs treated at the Veterinary Hospital of the State University of Maranhão from 2008 to 2015. We studied the medical records of 1089 dogs affected by neoplasms and treated at a hospital during the period of study, relating to the casuistry with their breed, age, sex and origin. The present study included 764 cases that were confirmed through cytopathology. The most prevalent tumors were transmissible venereal tumors (TVT) (20.17%), adenocarcinoma of the mammary gland (19.53%), mixed malignant tumor of the mammary gland (18.63%), mast cell tumor (11.31%), and mammary carcinoma (6.42%). Females with a mean age of 9.2 years were the most affected, as were SRDs, Poodles, American Pitbulls, and Dobermann Pinschers. According to the cytomorphogenetic classification, the round cell tumors were the most prevalent, with values close to those of epithelial, followed by mixed and mesenchymal cells.

ResumoObjetivou-se avaliar a adição do prebiótico mananoligossacarídeo (MOS 0,2%), probiótico (Bacillus subtilis 30g/tonelada) e antibiótico (bacitracina de zinco 125g/tonelada) em rações para leitões na fase de creche. Utilizaram-se 80 leitões (Danbread x Agroceres), sendo 40 machos e 40 fêmeas, com peso inicial de 7,1±0,0175kg, distribuídos em delineamento de blocos ao acaso, com quatro tratamentos e cinco repetições: 1 -controle; 2 -prebiótico; 3 -probióticos; e 4 -antibiótico. As variáveis avaliadas foram ganho de peso diário (GPD), consumo de ração diário (CRD), conversão alimentar (CA), consistência fecal e leucometria global. Aos 43 dias de idade, os animais apresentaram o mesmo ganho de peso (P>0,05), porém, a dieta contendo prebiótico aumentou o consumo (P>0,05); a conversão alimentar foi melhor na dieta controle (P<0,05). No período de 54 dias de idade dos animais, não houve diferença para ganho de peso diário (P>0,05), consumo de ração diário (P>0,05) e conversão alimentar (P>0,05). Não houve diferença para consistência fecal (P>0,05). O número de leucócitos aumentou aos 32 dias de idade, quando as dietas contendo prebióticos e probióticos foram utilizadas (P>0,05). A ração contendo prebiótico aumentou o número de monócitos (P<0,05) e a dieta contendo antibiótico proporcionou maior número de basófilos (P<0,05), aos 36 dias de idade dos animais; o número de linfócitos não foi alterado pelas dietas experimentais (P>0,05). As dietas não promoveram alterações nas imunoglobulinas IgA, IgM e IgG (P>0,05). Conclui-se que o uso de prebióticos, probióticos e antibióticos não influenciou o desempenho dos animais dos 22 aos 54 dias de idade. Palavras-chave: aditivos; consistência fecal; imunoglobulinas; suínos. AbstractThe objective of this study was to evaluate the addition of the prebiotic mannan oligosaccharide (MOS 0.2%), probiotic (Bacillus subtilis 30g/ton) and antibiotic (Bacitracin zinc 125g/ton) to piglets' feed in the post-weaning phase. Eighty (Danbread x Agroceres) pigs were used, that is, 40 males and 40 females, with initial weight of 7.1 ± 0.0175 kg. A randomized block design was used with four treatments and five replicates: 1 -Control; 2 -Prebiotic; 3 -Probiotic; 4 -Antibiotic. The variables evaluated were average daily gain (ADG), daily feed intake (DFI), feed conversion (FC) fecal consistency and leukocyte count. At 43 days of age, the animals presented the same weight gain

ResumoA neosporose é uma doença infecciosa, causada pelo Neospora caninum, protozoário intracelular obrigatório, formador de cistos, tendo o cão como principal hospedeiro definitivo. Este pode contaminar água e alimentos destinados a ruminantes, transmitindo assim a doença. Trata-se de uma das principais causas de abortos, gerando expressivos prejuízos econômicos na produção destes animais. A prevalência pode variar bastante em função do sistema de criação. Vários fatores de risco são associados a ocorrência da neosporose em ruminantes, dentre eles está a presença de cães em áreas destinadas a criação desses animais. O diagnóstico pode ser feito por métodos

BackgroundObesity is a chronic and multifactorial disease characterized by increased adipose tissue. In females, obesity leads to reduced ovulation and lower chances of conception in diseases like polycystic ovary syndrome, making it important to characterize complementary medicine to attenuate such deleterious effects. Therefore, the aim of this study was to assess the effects of a hydroethanolic extract from Syzigium cumini leaves in female reproductive impairments present in the obesity model of neonatal L-monosodium glutamate injection.MethodsNewborn Wistar rats received saline (CTRL) or L-monosodium glutamate 4 mg/g BW (MSG). At 90 days of age, CTRL and some MSG rats received saline, while others received hydroethanolic extract of S. cumini leaves (HESc 500 mg/kg/day, MSG-Syz group) for 30 consecutive days. Estrous cycle was determined by daily vaginal washes. On days 26 and 28 of treatment, oral glucose tolerance test and blood collection were performed for biochemical assessment. At the end, animals were euthanized during estrous phase; blood was collected to measure sex hormones and organs collected for weighing and histological evaluation.ResultsMSG-Syz showed reduced Lee Index, retroperitoneal fat pads and restored gluco-insulin axis. Moreover, HESc treatment reduced serum cholesterol levels when compared to MSG. Treatment with HESc did not restore the oligociclicity observed in obese animals, though MSG-Syz reestablished ovarian follicle health back to CTRL levels, with proliferating primordial follicles – these effects were followed by a decrease on periovarian adipocyte area.ConclusionsThis is the first report to show the reversibility of the reproductive dysfunctions seen in MSG female rats through ethnopharmacological treatment. Moreover, it expands the use of HESc as a prominent tool to treat metabolic and reproductive disorders. Finally, we provide novel evidence that, without a functioning hypothalamus-pituitary-gonads axis, metabolic improvement is ineffective for estrous cyclicity, but critical for ovarian follicle health.
