Salmonellosis remains an important cause of diarrheal illness in humans São Paulo State, Brazil. In this study were identified 3554 Salmonella isolates from human infections, during the period 1996-2003. Among 68 different serovars determined, S. Enteritidis was most frequent one gastrointestinal and extra-intestinal infections accounting for 67.4% all isolates. Typhimurium enterica subsp. (4,5,12:i:-) frequently isolated children aged < 1-4 year-old, contrast, people with likely to be 20-50...
BACKGROUND Tanychlamys indica (Godwin-Austen, 1883) was reported as a serious pest in India. The snails are voracious and feed on wide range of commercial crops. It has also been identified an intermediate nematode host Angiostrongylus cantonensis Bombay, T. recently introduced Brazil by international trade citrus fruit seedlings. First the State Santa Catarina then Paraná. Recently, it detected city São Paulo threatening to spread other Brazilian states. OBJECTIVES We report first record,...
Abstract The nematode Angiostrongylus cantonensis is the most common cause of neuroangiostrongyliasis (manifested as eosinophilic meningitis) in humans. Gastropod molluscs are used intermediate hosts and rats various species definitive this parasite. In study, we identified several environmental factors associated with presence abundance terrestrial gastropods an impoverished urban region Brazil. We also found that body condition, age co-infection other parasite Rattus norvegicus , well were...
Techniques for diagnosing intestinal parasites need technological advancements in the preanalytical (collection/processing) and analytical (detection) stages. The dissolved air flotation (DAF) technique effectively recovers from processed feces routine diagnosis. Artificial intelligence (AI) is a practical affordable alternative to modernize analysis stage of microscopy images generates high efficiency parasitological examination feces.
Angiostrongylus cantonensis, a rat lungworm, is one of the leading causes eosinophilic meningitis in humans. Infection humans occurs by ingestion intermediate hosts, undercooked paratenic hosts or contaminated vegetables and fruits mucus from infected molluscs. This zoonosis widespread tropical subtropical areas Southeast Asia, it has also been reported Pacific Islands as well other regions Americas. In Brazil, human cases angiostrongyliasis have since 2007 Southeast, Northeast, South...
Background:: Bordetella pertussis is the causative agent of pertussis. In Brazil, laboratory diagnosis based on culture. 2010, was standardized Real-Time PCR TaqMan® in routine diagnosis. Objectives:: The aim this study to evaluate impact achieved with introduction RT-PCR for and compare results obtained from Patients Methods:: 4,697 samples nasopharyngeal secretions collected suspected cases and/or contacts were analyzed culture, January 2008 until end December 2011. Results:: According...
Objetivo: As técnicas utilizadas no diagnóstico dos parasitos intestinais carecem de avanço tecnológico nas etapas pré-analítica (colheita/processamento) e analítica (detecção). A técnica flotação por ar dissolvido (FAD) se mostrou-se eficaz na recuperação processamento das fezes. Inteligência Artificial é uma alternativa prática acessível para modernizar a etapa análise imagens microscopia gerar alta eficácia. Nosso objetivo foi padronizar um protocolo fezes com em conjunto sistema...
BACKGROUND Angiostrongylus cantonensis is the etiological agent of neuroangiostrongyliasis in humans, which developed gastropods and vertebrate species, mainly rodents. Human transmission occurs through consumption molluscs paratenic hosts infected with L3, migration larvae to central nervous system causes eosinophilic meningitis. Laboratory diagnosis based on molecular immunological tests, using young or adult females as a source antigens. However, these tests give positive results only...
A Reação de Imunofluorescência Indireta (RIFI) foi utilizada para localizar antígenos em estruturas estágio-específicas cortes parafinados vermes fêmeas e tecidos caramujos do Gênero Biomphalaria infectados com larvas terceiro estágio Angiostrongylus cantonensis. Soros casos confirmados meningite eosinfílica foram usados avaliação da reatividade. não reagentes suspeitos; pacientes outras parasitoses indivíduos sem etiologias utilizados como controle reatividade cruzada. Anticorpos classe IgG...

Larval purification techniques encompass methods that depend on the biology of organism, its matrices and objectives.In this context, fecal samples are difficult substrates to handle due presence particles can compromise their use for research into various pathologies.This study presents a technique using semihydrolyzed collagen larvae from feces rodents experimentally infected with metastrongyles.
