Diamantina: an endemic new genus of Neotropical Atalophlebiinae (Ephemeroptera: Leptophlebiidae) evidenced by morphological and molecular data

Publication date: Available online 14 November 2019Source: Zoologischer AnzeigerAuthor(s): Frederico Falcão Salles, Jeane Marcelle C. Nascimento, Marina Monjardim, Roberta Paresque, Neusa Hamada, Eduardo DominguezAbstractA new genus and species is described based on nymphs and adults collected exclusively at the Chapada Diamantina National Park, in Brazil. The generic category of this new taxon was tested by reanalyzing a morphological dataset used to access the phylogenetic relationships of species of Ulmeritus and Ulmeritoides and by the use of molecular analysis, using two different genes. Both analysis corroborated the new taxon belongs to a new genus and species, sister group of Ulmeritus-Ulmeritoides, herein described as Diamantina ulmeri gen et sp. nov. Among members of this complex, Diamantina gen nov. presents a unique apomorphy: absence of setae on lateral margins of abdominal segments. Diagnostic features include the anterior position of the proximal row of setae on dorsal surface of labrum, the U shaped emargination of labrum, eyes of male imago widely separated and shape of penis lobes.

In this study, we generated two recombinant RABVs, rERAG333E/NiVG and rERAG333E/NiVF, expressing the NiV Malaysian strain attachment glycoprotein (NiV-G) or fusion glycoprotein (NiV-F) gene based on the rERAG333E vector platform. Both rERAG333E/NiVG and rERAG333E/NiVF displayed growth properties similar to those of rERAG333E and caused marked syncytia formation after co-infection in BSR cell culture. Adult and suckling mice intracerebrally inoculated with the recombinant RABVs showed NiV-G and NiV-F expression did not increase the virulence of rERAG333E. Oral vaccination with rERAG333E/NiVG either singularly or combined wi...

Conclusions: A significant increase (P = .02) in Lyme arthritis cases was observed at Oishei Children's Hospital of Buffalo. Lyme arthritis may clinically present similarly to other forms of arthritis, such as oligoarticular juvenile idiopathic arthritis, so health care providers should be aware of distinguishing clinical features, which include rapid onset of swelling and patient age. Because the geographic area of endemic Lyme disease is expanding, all health care providers need to be aware of Lyme arthritis as a possible diagnosis. PMID: 31819695 [PubMed]

Conclusion: Vulnerable populations were found to be less knowledgeable on risk factors and they had poor practice. Education had significant impact on knowledge and attitude of urban population; however, their practice did not improve with education. PMID: 31815581 [PubMed - as supplied by publisher]

ConclusionsAn overview of possible pathogenesis will gain a first insight into why HEV, traditionally recognized as only hepatotropic, can induce many neurological disorders represented by GBS. Moreover, understanding of the underlying mechanisms may contribute to development of a novel therapeutic strategy. This review also summarizes management and clinical characteristics of HEV ‐associated GBS, aiming to achieve early recognition and good recovery.

We report an exceptional case of cervical fungal mycetoma that occurred in a 13-year-old Senegalese child. He consulted for a cervico-submandibular tumefaction with multiple sinuses and black grains discharge evolving since 6 years, associated to laryngeal dyspnoea. Mycological examination with culture isolated Madurella mycetomatis. Cervical CT Scan showed bone and soft tissue invasion. Terbinafine alone was administered. During the evolution, tracheotomy was performed following the aggravation of the laryngeal disorders. Death from severe sepsis occurred after 8 months of evolution. The particularities of our case are th...

In this study, prophylactic passive immunization was performed in a miniature swine model, using two vaccination-induced monoclonal antibodies (mAb), JEV-31 and JEV-169. These were selected as representatives for antibodies reactive with the major antigenic structures in the E protein of JEV and related flaviviruses. JEV-31 recognizes the lateral ridge of E protein domain III (EDIII) whilst JEV-169 has a broad footprint of binding involving residues throughout domains I (EDI) and II (EDII) of the E protein. Detection of neutralizing antibodies in the serum of immunized animals mimics the presence of neutralizing antibodies...
