    Human Angiostrongyliasis Outbreak in Dali, China

    Angiostrongyliasis, caused by the rat lungworm Angiostrongylus cantonensis, is a potentially fatal food-borne disease. It is endemic in parts of Southeast Asia, the Pacific Islands, Australia, and the Caribbean. Outbreaks have become increasingly common in China due to the spread of efficient intermediate host snails, most notably Pomacea canaliculata. However, infections are difficult to detect since the disease has a rather long incubation period and few diagnostic clinical symptoms. Reliable diagnostic tests are not widely available. The described angiostrongyliasis epidemic in Dali, China lasted for eight months. Only 11 of a total of 33 suspected patients were clinically confirmed based on a set of diagnostic criteria. Our results demonstrate that the rapid and correct diagnosis of the index patient is crucial to adequately respond to an epidemic, and a set of standardized diagnostic procedures is needed to guide clinicians. Integrated control and management measures including health education, clinical guidelines and a hospital-based surveillance system, should be implemented in areas where snails are a popular food item

    CatĂĄlogo TaxonĂŽmico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

    The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the CatĂĄlogo TaxonĂŽmico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

    O presente trabalho trata do primeiro registro de Plesiophysa guadeloupensis (" Fischer" MazĂ©, 1883) no Estado do Rio de Janeiro, no municĂ­pio de Itaocara. Os exemplares foram coletados em uma ĂĄrea alagada situada no distrito de JaguarembĂ© em abril/maio de 2003 e março de 2005. SĂŁo mencionadas as espĂ©cies encontradas em simpatria com P. guadeloupensis, assim como algumas caracterĂ­sticas fĂ­sicas e quĂ­micas da ĂĄgua (pH, oxigĂȘnio dissolvido e temperatura), alĂ©m da atual distribuição geogrĂĄfica do gĂȘnero Plesiophysa no Brasil.<br>This paper deals with the first report of Plesiophysa guadeloupensis (" Fischer" MazĂ©, 1883) from Rio de Janeiro State, in the municipality of Itaocara. The gastropods were collected at a swamp situated in the district of JaguarembĂ© in April-May 2003 and March 2005. Other species found together with P. guadeloupensis are mentioned, as well as some physical and chemical characteristics of the water (pH, dissolved oxygen and temperature), and the geographical distribution of the genus Plesiophysa in Brazil

    Schistosomiasis haematobia: histopathological course determined by cystoscopy in a patient in whom praziquantel treatment failed EsquistossomĂ­ase hematĂłbica: seguimento histopatolĂłgico determinado por cistoscopia em um paciente com falha terapĂȘutica ao praziquantel

    Schistosomiasis haematobia or urinary schistosomiasis is one of the main public health problems in Africa and the Middle East. A single dose of 40 mg praziquantel per kg body weight continues to be the treatment of choice for this infection. The aims of this follow-up were to study the post-treatment course of a patient infected with S. haematobium and not submitted to re-exposure, and to identify complications of the disease and/or therapeutic failure after praziquantel treatment by histopathological analysis. Treatments were repeated under medical supervision to ensure the correct use of the drug. In view of the suspicion of lesions in cystoscopy, the patient was submitted to bladder biopsy. The histopathological characteristics observed in biopsies obtained, after each treatment, indicated viability of parasite eggs and activity of granulomas.<br>A EsquistossomĂ­ase HematĂłbica ou EsquistossomĂ­ase UrinĂĄria Ă© um dos principais problemas de SaĂșde PĂșblica na África e no Oriente MĂ©dio. Uma Ășnica dose de praziquantel 40 mg/kg de peso, continua sendo o tratamento de escolha para esta infecção. Os objetivos deste seguimento foram: avaliar o perĂ­odo pĂłs-tratamento de um paciente infectado com Schistosoma haematobium e nĂŁo submetido Ă  re-exposição e, identificar as complicaçÔes da doença e/ou falha terapĂȘutica, apĂłs o tratamento com praziquantel, por anĂĄlise histopatolĂłgica de material obtido por biĂłpsia vesical. O tratamento foi repetido sob supervisĂŁo mĂ©dica para assegurar o uso correto do medicamento. Na presença de lesĂ”es suspeitas a cistoscopia, o paciente foi submetido a biĂłpsia vesical. As caracterĂ­sticas histopatolĂłgicas observadas nos materiais obtidos por biĂłpsia, apĂłs cada tratamento, indicaram viabilidade de ovos e atividade dos granulomas
