common internal helminths of swine, flubendazole, dose range and efficacy studies

Zoonotic parasitic gastroenteritis has been well-known as a serious limitation to humans as well as livestock productivityin terms of man-power, pathology and fiscal losses, as human infection with these helminths from cattle can resultfrom consumption of meat containing the infective stage of the worm. This study therefore investigates the presence ofzoonotic helminth infections among cattle in Minna metropolis, and scientific basis for their potential transmission to humanpopulation. A total of 184 diarrhoeic faecal samples from cattle were collected from September 2014 to June 2015 in Minna,Niger state and processed using the direct faecal microscopic examination techniques. The obtained results showed that a total of 81 (44%) samples were positive including Ascaris sp, Fasciola gigantica, Trichuris sp. and Taenia sp. with infection rates of 22.3%, 12%, 2.2% and 0.5% respectively, and mixed infections of Fasciola gigantic with Ascaris sp. (4.3%) , and Ascaris sp. with Trichuris sp. (2.7%). Poor human hygiene, inadequate livestock husbandry managements and restriction of animals to residential areas are the major factors responsible for the high prevalence of zoonotic helminths and geo-helminths in the study area. Therefore veterinarians, animal handlers and livestock owners should practice personal hygienic and safe management practices for animal rearing and treatments.

Ascaris suum, Trichuris suis, naturally infected 10-week-old female pigs, anthelmintic activity of ivermectin administered subcutaneously or orally

Ascaris suum, swine, immune responses monitored by lymphocyte blastogenesis assays, indirect radioimmunoassays, peripheral eosinophil counts, and cutaneous delayed hypersensitivity reactions

Os suínos são acometidos por diversas enfermidades e as verminoses se constituem como as principais causas de não ganho de peso, competição e diminuição da conversão alimentar, descarte de vísceras ao abate e perdas financeiras. O nematoide Ascaris suum se constitui na principal parasitose na suinocultura nacional. Esse trabalho teve como objetivo avaliar o nível de infestação por A. suum em suínos em idade de abate provenientes de granjas tecnificadas localizadas na região do município de Piranga, região oeste da Zona da Mata, Minas Gerais, latitude 20º45'45"S, longitude 43º18'10"W. Os animais foram abatidos em três matadouros localizados no município de Piranga, e foram observados os tratos gastrintestinais dos suínos abatidos quanto à presença desse parasito. Foi observada a presença do nematoide em animais provenientes de 90% das granjas e a ocorrência total foi 22,4%, média de todo o período experimental. Também foi observado que, durante o período experimental, a ocorrência de A. suum no lume intestinal dos animais não apresentou diminuição e os protocolos de everminação não foram eficazes para a diminuição da ocorrência desses helmintos nas propriedades onde foram empregados. | Swine are affected by several diseases and worms constitute the main causes of absence of weight gain, competition and decreased feed conversion, discards of slaughter viscera and financial losses. The nematode Ascaris suum remains a major parasitic disease in national livestock pigs. The objective of this work was to evaluate the level of infestation by A. suum in pigs at slaughter age provenient from intensive production systems located in Zona da Mata region, latitude 20º45'45"S, longitude 43º18'10"W, in tropical Southeastern, Brazil. The animals were slaughtered at three slaughterhouses located in the municipality of Piranga, and their gastrointestinal tracts were observed in order to identify the presence of those helminthes. We observed the presence of nematode in animals from 90% of the farms and the total occurrence was 22.4%, media of all the experimental period. It was also observed that, during the experimental period, the occurrence of A. suum in the gastrointestinal tube did not present reduction and the protocol to administer anthelmintic were not efficient to decrease the occurrence this helminthes in proprieties in which they were applied.
