O objetivo deste estudo foi avaliar a ocorrência de helmintos intestinais em cavalos de trabalho utilizados em carroças na coleta de resíduos recicláveis e comparar com cavalos de lazer criados no município de Porto Alegre, Rio Grande do Sul, através de exames parasitológicos executados nos anos de 2009 a 2012. Foram incluídos nesta investigação 276 cavalos, 131 animais de trabalho do Projeto Carroceiro e 145 cavalos utilizados para lazer. Amostras fecais foram coletadas e processadas pela técnica de flutuação com solução de cloreto de sódio (D=1.20). A positividade foi de 73% (202/276), com 64,8% (94/145) e 82,4% (108/131), respectivamente, para cavalos de lazer e de trabalho, com maior frequência de ovos da família Strongylidae e baixa ocorrência de Parascaris equorum, Strongyloides westeri e Anoplocephala spp. Nas duas categorias a positividade foi alta mostrando que medidas profiláticas, terapêuticas e orientação aos proprietários quanto ao controle da verminose equina são necessárias.
Non-human primates can be reservoirs and carriers of diseases transmitted to humans. The objective of this work was to carry out a systematic bibliographical review on parasitosis with zoonotic potential that affect the genus Alouatta. In the period 2010-2021 the genders were registered: Ascaris, Ancylostoma, Bertiella, Strongyloides, Oesophagostomum, Trichostrongylus and Trichuris, and Bertiella sp. was the zoonotic parasite with the most reports. The southeast region had the greatest diversity of helminths, with six of the seven (6/7) genera of helminths with zoonotic potential, in Alouatta. Knowledge of the epidemiology and biological cycle can contribute to the prevention of parasitic zoonoses transmitted by contact between non-human primates and humans.
This study carried out a survey about enteropathogenic agents in domestic cats’ shelter as a stage of investigation for the intermittent chronic diarrhea. Individual fecal samples from 39 cats with free access to the external environment were submitted to parasitological examination, parvovirus, and coronavirus by PCR, and Cryptosporidium spp., Giardia spp. and Tritrichomonas foetus by real-time PCR. From the cats evaluated, 30 (76.9%) were positive for one or more enteric agents, and coinfections were observed in 11 cats samples (28.2%). Helminth eggs were observed in 48.7% of cats (19/30), 16 (41%) were positive for parvovirus or coronavirus and 25.6% (10/30) were infected by protozoa. From the positives for protozoa, five cats were positive to T. foetus (12.82%). The first finding of this protozoan through PCR was in the southern Brazil, and the second was in the whole country. Chronic diarrhea in cats may be multifactorial in shelter animals where the population density is high and the control of parasitic, and viral infections are deficient. Moreover, it is due to poor hygiene conditions in these shelters. The factors associated with the proliferation of infectious diseases in shelters are correlated with new pathogens infections such as T. foetus.

Estudou-se a prevalência de trematódeos no rúmen e retículo de 2.202 bovinos provenientes de 24 municípios do Estado do Rio Grande do Sul, através de necropsias efetuadas em matadouro. Constatou-se que 21 dos municípios estudados estavam positivos para Paramphistomum spp. e 26,3% dos rumens e retículos parasitados com o helminto. A prevalência deste trematódeo foi maior nos municípios de Santa Vitória do Palmar (100%); Capão do Leão (97,6%) e Palmares (90%).
