ABSTRACT

Gastrointestinal parasites are a significant challenge in sheep farming, and periparturient ewes are one of the most susceptible categories in sheep flocks. This study aimed to verify whether the injection of B vitamins at the acupuncture point governing vessel 14 (GV14) can influence the parasitic load or host-parasite interaction in naturally infected ewes during the peripartum period. Four weeks before parturition, 25 ewes were divided into five treatment groups: (1) Dose Control: 0.2 mL of B complex via IM; (2) Drug Control: 2 mL Complex B via IM; (3) Acupoint Control: 0.2 mL of Water at GV14 point; (4) Control; (5) Test group: 0.2 mL of B complex at the GV14 point. Treatments were performed at weeks -3, -1, 2, 4, and 6 about the parturition time. Fecal samples to estimate the parasitic load by fecal egg counts (FEC) and total blood samples for hemogram examination were performed seven days after the treatment, coinciding with weeks -2, 3, 5, and 7 about the parturition time. The number of peripheral eosinophils was higher in group 3 than in group 1 (p <0.05). Although groups 3 and 5 had lower mean values of FEC and higher hematological values at the time of weaning, these differences were not statistically significant (p> 0.05) according to the F test. However, all animals in groups 3 and 5 maintained low parasitism levels until the end of the experiment. Further studies should be performed with larger sample sizes and minor changes to the experimental protocol to elucidate the role of GV14 acupoint stimulation in the host-parasite relationship.(AU)


A parasitose gastrointestinal é o principal desafio sanitário para a criação de ovinos a pasto, e as ovelhas no periparto são uma das categorias mais susceptíveis a esta infeção no rebanho. O objetivo deste trabalho foi verificar se a injeção de vitaminas do complexo B no acuponto Vaso Governador 14 (VG14) poderia influenciar a carga parasitária ou modular a interação hospedeiro-parasito em ovelhas naturalmente infectadas no período de periparto. Quatro semanas antes da data prevista para o parto, 25 ovelhas foram divididas em cinco grupos de tratamento (1) Controle da dose: 0,2 mL de vitaminas do complexo B via IM; (2) Controle do fármaco: 2mL complexo B via IM; (3) Controle do Ponto: 0,2 mL de água destilada no ponto VG14; (4) Controle sem tratamento; (5) Grupo teste: 0,2 mL de complexo B no pontoVG14. Estes tratamentos foram realizados nas semanas -3; -1; 2; 4 e 6 em relação à data do parto. Amostras de fezes para contagem de ovos por grama de fezes (OPG), assim como amostras de sangue para realizar o hemograma, foram obtidas dos animais sete dias após os tratamentos, coincidindo com as semanas -2, 3, 5 e 7 do parto. O número de eosinófilos periféricos foi superior no grupo 3 se comparado ao grupo 1 (p <0,05). Os animais dos grupos 3 e 5 tiveram menores valores de OPG e maior hematócrito, mas estas diferenças não foram consideradas significativas pelo teste F (p> 0,05). No entanto, todas as ovelhas dos grupos 3 e 5 se mantiveram com níveis baixos de parasitismo durante todo o experimento. Sugere-se que novos estudos sejam realizados com algumas modificações deste protocolo a fim de aprofundar o conhecimento do potencial imunomodulador do acuponto VG14.(AU)

ABSTRACT

Abstract Knowledge of taxonomy and biodiversity of parasites is fundamental to better understand ecosystem dynamics. The objective of this study was to describe the helminth fauna of two species of marsupials in five fragments of the Atlantic rainforest in the western region of Paraná State, Brazil. In a total of 4050 trap-nights, the animals were captured using Sherman, Tomahawk, and Pitfall traps, euthanized, necropsied, and their organs inspected for helminths. After identification of the parasites, descriptors of infection, such as prevalence, mean abundance, mean intensity, and range of intensity, were calculated. Collectively, six helminth species were observed in 18 animals. The following five species were observed in Marmosa paraguayana: Viannaia hamata (58.8%), Gracilioxyuris agilisis (52.9%), Travassostrongylus sextus (17.6%), Oncicola luehei (5.9%), and Pritchardia boliviensis (5.9%). Whereas the following two species were observed in Monodelphis dimidiata: Trichohelix tuberculata (100%) and Travassostrongylus sextus (100%). This study represents a new locality record for all helminths described herein, and a new host for four helminth species. This is the first report on the helminth fauna of Monodelphis dimidiata, expanding knowledge about marsupials in the Brazilian Atlantic Forest.


Resumo Conhecimentos taxonômicos e da biodiversidade parasitária são fundamentais para uma melhor compreensão da dinâmica do ecossistema. O objetivo do estudo foi descrever a helmintofauna de marsupiais em cinco fragmentos de Mata Atlântica, na região Oeste do Estado do Paraná, Brasil. Em um total de 4.050 armadilhas/noite, os animais foram capturados com as do tipo Sherman, Tomahawk e Pitfall, eutanasiados, necropsiados e seus órgãos inspecionados em busca de helmintos. Após a identificação do parasita, foram calculados os indicadores de infecção (prevalência, abundância média, intensidade média e variação de intensidade). Seis espécies de helmintos foram observadas em dezoito animais; cinco em Marmosa paraguayana: Viannaia hamata (58,8%), Gracilioxyuris agilisis (52,9%), Travassostrongylus sextus (17,6%), Oncicola luehei (5,9%) e Pritchardia boliviensis (5,9%), e duas em Monodelphis dimidiata: Trichohelix tuberculata (100%) e Travassostrongylus sextus (100%). Este estudo representa um novo registro de localidade para todos os helmintos descritos e um novo hospedeiro para quatro deles. Trata-se do primeiro relato da helmintofauna de Monodelphis dimidiata, expandindo-se os conhecimentos sobre marsupiais na mata Atlântica brasileira.

ABSTRACT

The objective of this work was to evaluate the proteins, minerals, metabolites, and serum enzymes profile in Quarter Mile equines subjected to training for Team Penning competitions by comparing the results before and after training. The animals were from the Agricultural Exhibition Park of Uberlândia (CAMARU), in Uberlândia in the State of Minas Gerais, Brazil. These animals perform constant periodic training with an average duration of two and a half hours per training. Blood samples from twenty male and female equines were collected at the beginning and end of a 45-day interval and then analyzed. A 5 mL blood sample from each animal was collected before and after training by a jugular external venipuncture, and the samples were placed in a tube­without anticoagulant and containing separator gel­to obtain the serum. The components analyzed were: total proteins, albumin, globulins, albumin to globulin ratio (A:G), total and ionized calcium, phosphorus, calcium to phosphorus ratio (Ca:P), cholesterol, triglycerides, creatinine, urea, alkaline phosphatase, ɤ-glutamyl transferase, lactate dehydrogenase (LDH), aspartate amino transferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK). Statistical differences were observed with higher values after exercise for total calcium, ionized calcium, Ca: P ratio, creatinine and ALT and decreased concentrations were found for globulins, phosphorus, cholesterol and triglycerides. Despite the changes observed in the serum concentrations of some elements after exercises, it was concluded that the animals were in adequate physical condition to perform the proposed physical exercises.

ABSTRACT

The occurrence of Oncicola luehei is reported in a road killed crab-eating raccoon (Procyon cancrivorus) near the municipality of Uberlândia, Minas Gerais State. The animal was collected as part of a study that monitors wildlife road killing in the Triângulo Mineiro region. In necropsy, a single male acanthocephalan was recovered from the large intestine. The parasite was wrinkled, whitish in color, with a total body length of 15.88mm, globular proboscis (0.71 x 0.81mm) armed with 36 spiraled hooks, long lemniscus (7.30 x 0.81 mm) surpassing the anterior testis. The testes were ellipsoid in shape, disposed in tandem, the anterior measuring 1.44 x 0.53mm and the posterior 1.5 x 0.50mm. At the posterior part of the body, eight cement glands arranged in two rows of four, measuring 0.38 x 0.46 mm each. Based on this, the parasite was classified as Oncicola luehei. This study represents a new host and locality records for the parasite.
