“…Gastrointestinal parasites are important pathogens affecting animals and humans throughout the world (BLAGBURN et al, 1996;DEPLAZES et al, 2016). According to the World Health Organization (WHO), approximately 3.5 billion of people are affected by these parasites every year, being 450 million children who present clinical manifestations (OKYAY et al, 2004).…”

“…Similarly, rodents may represent an important risk for human beings as involved in the transmission of different pathogenic agents, including gastrointestinal parasites (e.g., Giardia duodenalis and Hymenolepis diminuta) (BACKHANS et al, 2013;LÕHMUS & ALBIHN, 2013;DEPLAZES et al, 2016). Amongst the most relevant are A. tubaeforme, A. brasiliensis and T. cati, causative agents of Cutaneous and Visceral Larva Migrans in humans, especially in children (DESPOMMIER, 2003;COELHO et al, 2004).…”

Gastrointestinal parasites are important pathogens affecting animals, some of them are of medical and veterinary concern. Although the dynamic of parasitic infections is a complex phenomenon that has been studied under experimental conditions, it shows several gaps in knowledge, especially in insular regions where a confined population of animals and parasites co-exists. In this study was assessed the parasitism by endoparasite gastrointestinal in feral cats (n = 37) and rodents (n = 30) from the Fernando de Noronha Archipelago; in addition, the risk of human infection and ecological implications of these findings were discussed. Out of all samples analysed, 100% scored positive for the presence of gastrointestinal parasites in both feral cats and rodents. A total 17 genera and/or species of endoparasite gastrointestinal were identified, Ancylostoma sp., Strongyloides sp., Trichuris campanula and Toxocara cati were the parasites more frequently in feral cats. In rodents Eimeria sp., Strongyloides sp. and Trichuris muris were parasites more frequently herein detected. Human population living in this area are at risk of parasite infections due to the population of rodents and feral cats in the archipelago.Keywords: Helminths, protozoal disease, zoonosis, synanthropic animals. ResumoParasitas gastrointestinais são importantes agentes patogênicos que afetam os animais, sendo alguns destes de interesse médico e veterinário. Embora a dinâmica das infecções parasitárias seja um fenômeno complexo que tem sido estudado sob condições experimentais, existem várias lacunas no conhecimento, especificamente em regiões insulares onde existem populações confinadas de animais e parasitas. Neste estudo foi avaliado o parasitismo por endoparasitas gastrointestinais em gatos ferais (n = 37) e roedores (n = 30) do Arquipélago de Fernando de Noronha. Além disso, discutiu-se o risco de infecção humana e implicações ecológicas desses achados. De todas as amostras analisadas, 100% obtiveram resultados positivos para a presença de parasitos gastrointestinais tanto em gatos ferais quanto em roedores. Um total de 17 gêneros e/ou espécies de endoparasitos gastrointestinais foram identificados, Ancylostoma sp., Strongyloides sp., Trichuris campanula e Toxocara cati foram os parasitos mais frequentes em gatos ferais. Em roedores Eimeria sp., Strongyloides sp. e Trichuris muris foram os mais detectados. A população humana que vive nesta área corre o risco de infecções parasitárias, devido à população de roedores e gatos ferais no arquipélago.Palavras-chave: Helmintos, doenças protozoárias, zoonoses, animais sinantrópicos.

“…Therefore, the use of appropriate diagnostic procedures is of fundamental importance, together with disease awareness. Among the procedures for parasite detection, the Baermann method (Deplazes et al 2016) performed with faecal samples possibly collected over three consecutive days is recommended for the isolation of first stage larvae (L1), which can be observed microscopically. These need to be distinguished from other larvae present in faeces according to morphological characters.…”

Faecal detection of the lungworms Crenosoma vulpis and Angiostrongylus vasorum and serological detection of A. vasorum in dogs from the Czech Republic

Dogs are definitive hosts for the lungworms Crenosoma vulpis and Angiostrongylus vasorum.Intermediate hosts are gasteropoda (Mollusca). In the past, lungworms in dogs were rarely identified in the Czech Republic and in neighbouring countries. A total of 253 dogs were sampled for faecal analysis performed by the Baermann method for isolation of first stage larvae (L1) of lungworms. A total of 193 serum samples were collected and analysed by ELISA for the detection of a circulating antigen and specific antibodies against A. vasorum. All dog owners were asked to fill out a questionnaire. Nine dogs (4.7%, 95% Confidence Interval, CI: 2.2-8.7%) were positive for the A. vasorum circulating antigen, seven dogs (3.6%, CI: 1.5-7.3%) had specific antibodies against A. vasorum; of these, three animals (1.6%, CI: 0.3-4.5%) were positive for both ELISAs. Most of them were under the age of three years. Only three of 13 seropositive dogs were not healthy, namely, in one dog vomitus was observed and two dogs were pyretic. Faecal samples of 5 dogs were positive for C. vulpis L1 (2.0%, CI: 0.6-4.6%). Angiostrongylus vasorum L1 were found in the faecal sample of one dog (0.4%, CI: 0.01-2.2%). This study illustrates the wide-spread occurrence of lungworms in the Czech Republic. Disease awareness of lungworms among animal owners and veterinarians should be implemented.

“…The genera Pelodera and Rhabditis are also members of the order Rhabditida, and each genus contains a large number of species with differing lifestyles (Deplazes et al 2016). Several species are considered to be largely saprophytic, but some are facultative, opportunistic parasites, whereas others appear to have a period of obligate parasitism in their lifecycles.…”

Non-Strongyloides rhabditida identified in fecal samples – two case reports: lessons learned from morphological and molecular diagnostic approaches

2016

Nematodes in the order Rhabditida, including species of Strongyloides and Pelodera, may be parasites of domestic animals. In this paper, we describe two apparent cases of rhabditid infections, one in a dog and one in a litter of piglets. The dog infection was originally considered likely to be an infection with Strongyloides, based on superficial morphological examination and PCR results without sequencing. However, more careful morphological analysis and inclusion of several molecular analyses, including sequencing, revealed that an infection with Pelodera sp. was more likely, probably Pelodera pseudoteres. Treatment with fenbendazole and selamectin was apparently successful. Similarly, based on both morphological and molecular analyses the apparent piglet infections were considered most likely to be with Rhabditis spp., possibly Rhabditis axei. The detection of larvae of nematodes in the order Rhabditida in fecal samples, particularly from dogs, may easily be considered as being indicative of Strongyloides infection. Given the zoonotic potential of canine Strongyloides, correct diagnosis is important. However, as illustrated by these two cases, careful morphological examination and measurement, supported by full molecular investigations, including sequencing, are essential in order to avoid this misdiagnosis.
