This study aimed to analyze the parasites infesting pigs and their producers on family farms in Tanguá, RJ, Brazil, and to conduct extension activities between 2018 and 2019. Fecal samples were collected from 132 pigs, as well as, skin scrapings from the ears of 125 animals. In addition, 36 stool specimens from farmers and their families were analyzed. The collected material was processed by direct examination, sedimentation and flotation techniques. Gastrointestinal parasites were detected in 88.6% of the pigs, especially coccidia (71.8%), Balantioides coli (55%), strongyles (40.2%) and Strongyloides ransomi (31.6%) which showed statistically significance (p<0.05). Ectoparasites were identified in 16% of the pigs, mostly Sarcoptes scabiei var. suis (76.2%). Parasites were detected in 19.4% of the humans, including, Entamoeba coli (19.4%), Ascaris lumbricoides (8.3%) and Trichuris trichiura (5.5%). The frequency of B. coli and S. scabiei var. suis (p<0.05) were statistically significant, when analyzing the age group of the animals, having been more detected in the older years, fatterners phase. The pig farmers participated in these activities extension, which included lecture and “field day”, aimed at imparting information about parasites and their prophylaxis. The situation in Tanguá pig farms reinforces the need to carry out programs that provide technical support to these farmers, whose livelihood depends on pig farming.

At the national level, there are several types of pig breeding that employ diversified technologies and management, depending on the financial conditions of each producer. This difference, evidenced in the productions, ends up reflecting the presence of infectious agents in animals, including infections determined by gastrointestinal parasites such as helminths and protozoa. Due to the lack of information and the importance of this topic, this study aimed to report, through a parasitological survey, the frequency of gastrointestinal parasites detected in pig raised on a farm located in the Nova Iguaçú city, Rio de Janeiro. For this purpose, 200 fecal samples from 40 pens were collected. Fecal samples were processed in a pool using the Lutz spontaneous sedimentation technique. In 100% of the samples, forms of parasites were detected, being mainly strongyles eggs (97.5%), followed by coccidia oocysts (87.5%), Balantioides coli cysts (75%), Strongyloides ransomi eggs (42.5%), Ascaris suum (25%) eggs and Trichuris suis (7.5%), with statistically significant differences between these frequencies. From the parasitological survey carried out, it was possible to identify a high frequency of parasites in the fecal samples of the animals, confirming that the pig farm had precarious conditions for sanitary management.

This purpose of this study was to compare the efficiency of the McMaster and Mini-FLOTAC quantitative techniques in the investigation of helminths in feces of pigs. An analysis was made of 74 fecal samples from pigs raised on family farms located in Rio de Janeiro, Brazil. These were analyzed by the Mini-FLOTAC and McMaster techniques in a solution of 1,200g/mL NaCl. This investigation revealed a superiority in the frequency of all helminths detected by Mini-FLOTAC, including Ascaris suum, Trichuris suis, strongyles and Strongyloides ransomi. The Kappa index revealed substantial agreement in all comparisons made in relation to the frequency of positive samples. However, significant statistical differences in the comparison of EPGs between McMaster and Mini-FLOTAC were observed for all nematodes (p ≤0.05). Higher values of Pearson’s linear correlation coefficient (r), between the techniques in relation to EPG were observed for A. suum and T. suis, differently from what was observed for strongyles and S. ransomi. Mini-FLOTAC proved to be a more satisfactory and reliable technique both for the diagnosis of parasites and for the determination of EPG in pig feces due to the larger size of its counting chambers, thus increasing the helminth egg recovery rates.

The parasites infesting pigs and pig farmers on family farms in Rio de Janeiro city, Brazil, were analyzed, and extension activities were carried out to impart information about parasites. Between 2020 and 2021, fecal samples were collected from 180 pigs as well as ear scrapings from 142 pigs. In addition, 34 stool specimens from farmers and their families were analyzed. The collected material was processed by parasitological techniques. Parasites were detected in 86.1% of the pigs, forms of phylum Ciliophora (70.5%), strongylids (56.7%), Strongyloides ransomi (44.4%), coccidia (38.3%) and Ascaris suum (32.2%). Sarcoptes scabiei var. suis were identified in 3.5% of the pigs. An analysis of infections by age group revealed that the general frequency of phylum Ciliophora and strongylid parasites was statistically significant. Other factors also associated with the frequency of the parasites included the type of food fed to the pigs, cleaning of the facilities, care of piglets and type of facility. The frequency of intestinal parasites of farmers themselves was low; however, the high rate of parasite infections detected in pigs highlighted the precarious conditions of hygiene of the farms. Lastly, the farmers’ participation in extension activities was a step forward in actions to improve their farm management.

Este estudo teve como objetivo realizar um levantamento de curtas-metragens de animação que abordaram conteúdo de parasitologia, analisando formato e conteúdo. O mesmo foi realizado em três etapas: a primeira consistiu no levantamento dos vídeos online, e na segunda e terceira foram recuperadas informações de formato e conteúdo. Foram recuperados 21 curtas-metragens brasileiros. Destes, mais de 45% foram produzidos por Instituições públicas e tinham a duração entre 4 a 6 minutos. Cerca de 52,4% utilizou o diálogo entre personagens e narração para mediar informação, retratando o médico como principal profissional. As parasitoses mais abordadas foram malária e esquistossomose. Pode-se concluir que o curta-metragem tem elevado potencial para ser aplicado nas escolas com ferramenta midiática por ser um vídeo objetivo.
