The present study aims to provide a comprehensive analysis of clinical characteristics and treatment response among patients in the Amazon region of Brazil and conduct a retrospective cohort study at a prominent referral hospital in the State of Par, Brazil, from 2012 to 2020. The M. avium group represented 58.9% of cases, followed by M. intracellulare (35.7%), M. colombiense (3.6%), and M. chimaera (1.8%). The majority of patients (73.2%) were female and with an average age of 63 years. Primary clinical manifestations included persistent cough and sputum production. The Charlson comorbidity index (CCI) averaged 2.47, with 36.3% of patients having a CCI score equal to higher than 3. Notably, over 70% of patients had received treatment for pulmonary tuberculosis before initiating treatment for MAC infection. The fibrocavitary radiologic form was the most prevalent (55.4%), frequently exhibiting a bilateral distribution (53.6%). Antimicrobial susceptibility revealed a significant prevalence of MAC resistance to drugs in the therapeutic regimen. Despite this, most of the patients experienced clinical improvement (50%). In conclusion, this study highlights a higher prevalence of MAC infections among middle-aged women, with a history of pulmonary tuberculosis treatment and presenting the fibrocavitary radiological form was predominant.展开更多

The objective was verifying the relationship between SNPs 2029 and 2258 of the TLR-2 gene and leprosy. Blood samples from 127 individuals were analyzed: 45 patients, being 34 multibacillary (MB) and 11 paucibacillary (PB) and 82 contacts, in the municipalities of the State of Pará-Brazil. SNPs 2029 and 2258 of the TLR-2 gene were genotyped by sequencing on the ABI 3130 Genetic Analyzer (Applied Biosystems), analyzed using Fisher’s exact test. Distribution of SNP 2029 genotypes: all MB individuals presented the C/C genotype and the mutant (C/T) genotype was observed in contacts and PB. Alleles: all MB individuals presented only C allele and the mutant allele (T) was observed in contacts and PB. SNP 2258 genotypes: 79 contacts had G/G genotype and only 3 had G/A genotype, the MB group had only G/G genotype and the PB group was predominant G/G, with only 1 G/A genotype. Alleles: all MB individuals had allele G and the mutant allele (A) was observed in contacts and PB. The association between the SNPs and the susceptibility or protection to leprosy was not observed.展开更多

文摘Dothideomycetes comprise a highly diverse range of fungi characterized mainly by asci with two wall layers(bitunicate asci)and often with fissitunicate dehiscence.Many species are saprobes,with many asexual states comprising important plant pathogens.They are also endophytes,epiphytes,fungicolous,lichenized,or lichenicolous fungi.They occur in terrestrial,freshwater and marine habitats in almost every part of the world.We accept 105 families in Dothideomycetes with the new families Anteagloniaceae,Bambusicolaceae,Biatriosporaceae,Lichenoconiaceae,Muyocopronaceae,Paranectriellaceae,Roussoellaceae,Salsugineaceae,Seynesiopeltidaceae and Thyridariaceae introduced in this paper.Each family is provided with a description and notes,including asexual and asexual states,and if more than one genus is included,the type genus is also characterized.Each family is provided with at least one figure-plate,usually illustrating the type genus,a list of accepted genera,including asexual genera,and a key to these genera.A phylogenetic tree based on four gene combined analysis add support for 64 of the families and 22 orders,including the novel orders,Dyfrolomycetales,Lichenoconiales,Lichenotheliales,Monoblastiales,Natipusillales,Phaeotrichales and Strigulales.The paper is expected to provide a working document on Dothideomycetes which can be modified as new data comes to light.It is hoped that by illustrating types we provide stimulation and interest so that more work is carried out in this remarkable group of fungi.

文摘Asexually reproducing fungi play a significant role in essential processes in managed and wild ecosystems such as nutrients cycling and multitrophic interactions.A large number of such taxa are among the most notorious plant and animal pathogens.In addition,they have a key role in food production,biotechnology and medicine.Taxa without or rare sexual reproduction are distinguished based on their sporulating structures and conidiomata in traditional morphology-based taxonomy.The number,variation and diversity of asexually reproducing taxa are insufficiently known,even though fungi capable of asexual reproduction may provide an untapped,rich biological resource for future exploitation.Currently,ca.30,000 asexual species belonging to ca.3800 genera have been reported(including 1388 coelomycetous and 2265 hyphomycetous genera).Recent reports(2017–2020)reiterate that the number of asexually producing fungi is higher than the number of frequently sexually-reproducing fungi.With the advent of molecular tools and the abandonment of the dual nomenclature system for pleomorphic fungi,priority criteria were established and revisited in the latest outline of fungi and fungus-like taxa.However,species numbers and taxonomic boundaries of pleomorphic taxa and their synanamorphs or synasexual morphs have yet to be addressed.The number of species of speciose genera(e.g.Alternaria,Aspergillus,Cercospora,Fusarium,Phoma and Pseudocercospora),cryptic species,species of pleomorphic genera,less studied life modes(such as lichenicolous taxa,taxa from extreme environments)and species from biodiversity-rich areas still need evaluation to achieve more reliable estimates of their diversity.This paper discusses the current knowledge on the matter,with diversity estimates,and potential obstacles in several chapters on(1)speciose genera;(2)pleomorphic genera;(3)cryptic species;(4)well-studied but insufficiently resolved taxa,e.g.leaf inhabiting species,marine fungi,(5)less studied life modes,e.g.lichenicolous,rock-inhabiting fungi,insect-associated and yeast-forming taxa and(6)species from biodiversity-rich areas.
