“…Although this study did not aim to compare the flotation solutions used in the quantitative Mini-FLOTAC technique, it was observed that the sodium chloride solution obtained the highest recovery rates of parasitic structures, mainly thin-shelled nematode eggs. This result was already expected, as the greater sensitivity of detection of these eggs by this solution has already been reported [55].…”

Aim: Determining gastrointestinal parasites’ frequency in non-human primates (NHPs) and handlers in different Brazilian institutions, and associate it with management information. Methods: Different institutions in São Paulo (A), Brasília (B), Rio de Janeiro (C), Pará (D) and Santa Catarina (E) were included in the study. Fecal samples were processed by using coproparasitological techniques; information about NHP handling and professionals’ routine were collected through the use of questionnaires. Results: In total, 33.1% of 511 NHP samples were positive for parasites; the Entamoebidae Group and Strongyloides sp.-compatible eggs were the most detected protozoa and helminths, respectively. The Entamoebidae Group was mainly diagnosed in Alouatta from Institutions E and D, and was also the only parasite detected in handlers. Strongyloides-compatible eggs were mostly evident in fecal samples collected from Cebidae from Institutions B and D. Some risk factors associated with parasite infection were a high number of animals in the same enclosure and their use for research protocol purposes, whereas quarantine, a post-infection vacant period in enclosures and antiparasitic supply were categorized as protective factors against these agents’ infection. Conclusions: Parasites showing different transmission routes but concomitantly circulating in NHP institutions located in different Brazilian regions were identified in the current study, with an emphasis on those presenting zoonotic potential.

“…A gender-based pairing between the severely asthmatic horses and their farm mates was not always possible, since some farms only possessed adult animals of a specific gender. Nonetheless, gender is not a predisposing factor for the development of SEA [ 5 , 44 ], and recent studies reported no significant differences in the excretion of helminth eggs between genders for animals of the same age, kept under a similar management program [ 45 , 46 , 47 , 48 ]. For this reason, we prioritized pairing the animals according to their age rather than their gender, with 16 out of the 20 SEA–control pairs still having the same gender.…”

The relationship between helminth infection and allergic diseases has long intrigued the scientific community. This interaction was previously studied in a horse family with high incidence of severe equine asthma and in non-related severely asthmatic horses from equine hospital referrals in Switzerland. Our aim was to determine if this interaction would also be observed in a group of non-related client-owned severely asthmatic horses living in a Mediterranean climate and recruited through a first-opinion veterinarian group. Fecal samples from severe equine asthma-affected and healthy horses living in the same farms and subjected to identical environmental and deworming management were evaluated qualitatively and quantitatively. Strongyle-type eggs and Cyathostomum sensu latum larvae were the most abundant parasites in the studied population of horses; no significant differences between the groups were observed regarding the types of egg and infective larvae. However, we observed significant differences in the number of eggs and infective larvae per gram of feces shed, as this number was significantly lower in the SEA group than in the healthy horses. This may indicate that severely asthmatic horses have an intrinsic resistance to gastrointestinal helminths. Further studies in a larger population of horses are required to ascertain the immunological mechanisms responsible for these findings.
