Les stades larvaires de Rhammatocerus schistocercoides (Rehn, 1906), criquet ravageur de l´état du Mato Grosso, Brésil (Orthoptera, Acrididae).

A fase larval do Rhammatocerus schistocercoides (Rehn, 1906), importante gafanhoto praga do Estado do Mato Grosso, no Brasil, são descritos pela primeira vez no trabalho

Integração de dados georreferenciados no mapeamento dos biótopos do gafanhoto praga do Mato Grosso.

Divulga os resultados do projeto, realizado em parceria com o PRIFAS (França), sobre os gafanhotos do Estado do Mato Grosso, particularmente a espécie Rhammatocerus schistocercoides (Rehn, 1906) (Acrididae, Gomphocerinae). O conhecimento sobre sua bioecologia e sobre o determinismo de suas populações era muito limitado, sendo restrito o número de publicações científicas sobre o assunto. As informações encontravam-se, sobretudo, nos relatórios de instituições de pesquisa e de controle fitossanitário nacionais e internacionais, assim como em numerosos artigos de jornais e de revistas. Após três anos de pesquisas, com financiamento aprovado pelo Programa de Cooperação Científica Brasil e CCE, os resultados obtidos já permitem uma idéia bem mais clara do fenômeno, além de inferências sobre as potencialidades e adequabilidade de uso do sensoriamento remoto e do geoprocessamento para abordagens de problemas entomológicos em grande escala

Early respiratory viral infections in infants with cystic fibrosis

This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Background Viral infections contribute to morbidity in cystic fibrosis (CF), but the impact of respiratory viruses on the development of airway disease is poorly understood. Methods Infants with CF identified by newborn screening were enrolled prior to 4 months of age to participate in a prospective observational study at 4 centers. Clinical data were collected at clinic visits and weekly phone calls. Multiplex PCR assays were performed on nasopharyngeal swabs to detect respiratory viruses during routine visits and when symptomatic. Participants underwent bronchoscopy with bronchoalveolar lavage (BAL) and a subset underwent pulmonary function testing. We present findings through 8.5 months of life. Results Seventy infants were enrolled, mean age 3.1 ± 0.8 months. Rhinovirus was the most prevalent virus (66%), followed by parainfluenza (19%), and coronavirus (16%). Participants had a median of 1.5 viral positive swabs (range 0–10). Past viral infection was associated with elevated neutrophil concentrations and bacterial isolates in BAL fluid, including recovery of classic CF bacterial pathogens. When antibiotics were prescribed for respiratory-related indications, viruses were identified in 52% of those instances. Conclusions Early viral infections were associated with greater neutrophilic inflammation and bacterial pathogens. Early viral infections appear to contribute to initiation of lower airway inflammation in infants with CF. Antibiotics were commonly prescribed in the setting of a viral infection. Future investigations examining longitudinal relationships between viral infections, airway microbiome, and antibiotic use will allow us to elucidate the interplay between these factors in young children with CF
