“…suum infection has been reported to result in a visceral larval migrans (VLM) pattern of pulmonary eosinophilia (107,133,160). However, whether these cases are truly representative of Ascaris-associated VLM, with liver and lung involvement, rather than either VLM due to Toxocara or misclassified Löffler's syndrome, remains an unresolved issue (142).…”

SUMMARY This review starts with discussions of several infectious causes of eosinophilic pneumonia, which are almost exclusively parasitic in nature. Pulmonary infections due specifically to Ascaris , hookworms, Strongyloides , Paragonimus , filariasis, and Toxocara are considered in detail. The discussion then moves to noninfectious causes of eosinophilic pulmonary infiltration, including allergic sensitization to Aspergillus , acute and chronic eosinophilic pneumonias, Churg-Strauss syndrome, hypereosinophilic syndromes, and pulmonary eosinophilia due to exposure to specific medications or toxins.

RESUMOEste trabalho descreve um relato de caso de parasitas intestinais encontrados em um suíno criado sob condição artesanal no município de Piripiri, PI, onde foi levado e abatido em matadouro de inspeção municipal de Teresina, PI. Durante o abate, na linha de inspeção, foi verificada a presença de alguns nematódeos da espécie Ascaris suum e de acantocéfalos da espécie Macracanthorhynchus hirudinaceus na mucosa intestinal deste animal. Os vermes foram retirados do intestino, colocados em recipiente contendo álcool e levados ao Laboratório de Parasitologia do Departamento de Parasitologia e Microbiologia do Centro de Ciências da Saúde da Universidade Federal do Piauí para confirmação da identificação das espécies. A presença e a persistência de Ascaris suum no meio devem-se, principalmente, a sua capacidade de sobrevivência às condições ambientais, sendo altamente capazes de reinfectar outros animais. A transmissão por M. hirudinaceus se dá pela ingestão de hospedeiros coleópteros parasitados, importante fonte de infecção para o animal. No estado do Piauí, o relato da ocorrência desses parasitas em suínos não é conhecida, sendo importante uma avaliação mais detalhada em suínos abatidos em matadouros oficiais. PALAVRAS-CHAVE: abate, acantocéfalo, Ascaris suum, suíno. INTESTINAL PARASITES FOUND IN SLAUGHTERED SWINE AT MUNICIPAL INSPECTION SLAUGHTERHOUSEABSTRACT This paper describes a case report of intestinal parasites found in a swuine, created under a handicraft condition in the municipality of Piripiri, PI, where it was taken and slaughtered in a slaughterhouse of municipal inspection of Teresina, PI. During the slaughter, in the inspection line, the presence of some nematodes of the species Ascaris suum and of acanthocephalus of the species Macracanthorhynchus hirudinaceus was verified in the intestinal mucosa of this animal. The worms were removed from the intestine, placed in a container containing alcohol and taken to the Laboratory of Parasitology of the Department of Parasitology and Microbiology of the

“…The cause could be in the great amount of serotypes of viruses and bacteria. Helminths often belong among the opportune pathogens that attack the organisms of patients with serious respiratory disease (Shuji et al, 2006). Königová et al (2010) found in paediatric patients at the age of 9 months up to 16 years with acute or chronic respiratory and gastrointestinal infection the occurrence of A. lumbricoides and T. trichuria.…”

Endoparasitoses in hospitalised paediatric patients with pulmonary disease

SummaryFaeces examination of hospitalised paediatric patients with respiratory diseases (recurrent and chronic bronchitis, bronchial asthma, contact with TBC, active TBC, rhinopharyngitis, bronchitis, pneumonia, cystic fibrosis, fluidothorax, pleuropneumonia) revealed the total prevalence of endoparasites of 19.85 %, out of which the prevalence of helminth was 7.35 %. Following genera, or species were represented Ascaris lumbricoides, Trichuris trichuria, Hymenolepis spp., Enterobius vermicularis. The total prevalence of protozoa was 12.50 % in the following representation: Cryptosporidium spp., Entamoeba spp., Isospora spp., Giardia spp. Out of helminthoses the greatest representation was in Ascaris lumbricoides 4.41 %, and out of protozoa Cryptosporidium spp. 6.62 %. In paediatric patients the increased levels of IgE antibodies were found for individual age groups as well as higher values of eosinophiles (Eo > 5 %), lymphocytes (Lym > 56 %), and Creactive protein (CRP > 8 mg.l -1 ). Statistically significantly (P < 0.05) higher level (above the reference values) of IgE, Eo, Lym were found in the patients with helminthoses.
