1Forest Biodiversity Assessment in Peruvian Andean Montane Cloud Forest显示文摘Cloud forests are unusual and fragile habitats, being one of the least studied and least understood ecosystems. The tropical Andean dominion is considered one of the most significant places in the world as regards biological diversity, with a very high level of endemism. The biodiversity was analysed in an isolated remnant area of a tropical montane cloud forest known as the 'Bosque de Neblina de Cuyas', in the North of the Peruvian Andean range. Composition, structure and dead wood were measured or estimated. The values obtained were compared with other cloud forests. The study revealed a high level of forest biodiversity, although the level of biodiversity differs from one area to another: in the inner areas, where human pressure is almost inexistent, the biodiversity values increase. The high species richness and the low dominance among species bear testimony to this montane cloud forest as a real enclave of biodiversity.Alicia Ledo Sonia Condés Iciar Alberdi 2012Journal of Mountain Science2012,9,3:5
2Streptococcus agalactiae:Identification methods,antimicrobial susceptibility, and resistance genes in pregnant women显示文摘BACKGROUND Group B Streptococcus(GBS)is a normal component of the gastrointestinal and genital microbiota in humans and can lead to important infections in newborns.AIM To compare GBS isolation and identification methods as well as to assess the antibiotic susceptibility and to identify resistance genes in GBS strains from pregnant women attended in healthcare services from the city of Vitória da Conquista,in Bahia State,Brazil.METHODS From January 2017 to February 2018,vaginorectal swabs were obtained from 186 participants and the samples were seeded onto chromogenic agar for GBS before and after inoculation in selective broth.Confirmatory identification using 3 CAMP and latex tests was performed in samples with GBS-suggestive colonies.Then,disk diffusion antibiograms were performed in GBS-positive samples,and the detection of the resistance genes ermB,ermTR,mefA,and linB in the clindamycin and/or erythromycin-resistant samples was carried out.RESULTS Thirty-two samples(17.2%)were GBS-positive.The culture in chromogenic agar after sample incubation in selective broth was the most sensitive method(96.9%)for GBS detection.All isolates were susceptible to penicillin,ampicillin,cefotaxime,and vancomycin.Clindamycin resistance was observed in 6 samples(18.8%),while 8 samples(25%)were erythromycin-resistant.All erythromycin and/or clindamycin-resistant GBS strains had negative D-tests.Two strains(25%)presented an M phenotype and 6 isolates(75%)presented a cMLSB phenotype.The ermB gene was identified in 4 samples(44.4%),the mefA gene was also found in 4 samples(44.4%),the ermTR gene was identified in 1 isolate(11.1%),and the linB gene was not found in any isolate.CONCLUSION This study evidenced that the screening for SGB can be performed by means of various methods,including chromogenic media,and that the chemoprophylaxis for pregnant women who cannot use penicillin must be susceptibility-guided.Fabrícia Almeida Fernandes Santana Tais Viana Ledo de Oliveira Marcelo Barreto de Souza Filho Lucas Santana Coelho da Silva Breno Bittencourt de Brito Fabrício Freire de Melo Cláudio Lima Souza Lucas Miranda Marques Márcio Vasconcelos Oliveira 2020World Journal of Clinical Cases2020,8,18:2
3Pseudoclitocybaceae fam. nov. (Agaricales, Tricholomatineae), a new arrangement at family, genus and species level显示文摘A new classification of several clitocyboid taxa is here proposed to accommodate results from multigenic phylogenetic inference.The analysis of ITS rDNA as well as a combined dataset including 18S and 28S rDNA,tef1 and rpb2 data,support significantly a shared monophyletic origin of the genera Pseudoclitocybe,Musumecia and Pogonoloma,and the species Clitocybe alexandri and C.harperi.The new family Pseudoclitocybaceae is here proposed to name this clade,characterized by the presence of loop-like clamp connections in most species,absence of cystidia,and parallel hymenophoral trama with broad,cylindrical hyphae with intracellular granulations.The new genera Clitopaxillus and Harmajaea are proposed to accommodate the type species C.alexandri and H.harperi,as well as the combination H.wellsiae.In addition,two new species are described:C.fibulatus has a differential distribution of clamp connections in the basidiome,while H.guldeniae is,by now,an exclusively European taxon with brownish pileus,somewhat decurrent gills,ovoid spores and basidia longer than those of H.harperi.Finally,the species concept within Pseudoclitocybe and Pogonoloma is discussed and descriptions of the most representative species are provided.Pablo Alvarado Pierre-Arthur Moreau Balint Dima Alfredo Vizzini Giovanni Consiglio Gabriel Moreno Ledo Setti Tapio Kekki Seppo Huhtinen Kare Liimatainen Tuula Niskanen 2018Fungal Diversity2018,,3:2
