Disseminated cutaneous leishmaniasis due to Leishmania(Leishmania) amazonensis in human immunodeficiency virus(HIV)-infected patients: A report of two cases

引用

Asian Pacific Journal of Tropical Medicine 2021年第6期14卷 281-284页

作者： camila F Araújo Iara B N Oliveira Murilo B silveira Fátima Ribeiro-Dias Hospital de Doenças Tropicais Doutor Anuar Auad GoiâniaGoiásBrazil Laboratório de Imunidade Natural(LIN) Instituto de Patologia Tropical e Saúde PúblicaUniversidade Federal de GoiásGoiâniaGoiásBrazil

Rationale: Co-infection of human immunodeficiency virus(HIV) and Leishmania spp. has impact on clinical and therapeutic outcomes of leishmaniases. Most studies do not present the identification of Leishmania species causing American tegumentary leishmaniasis in co-infections. In the Americas, Leishmania(L.) Viannia(V.) braziliensis and L.(V.) guyanensis have been identified. Patient concerns: In this study, two cases of American tegumentary leishmaniasis in patients infected with HIV are described. Patients presented several lesions with rapid dissemination and mucosal involvement. Diagnosis: Disseminated cutaneous leishmaniasis caused by L. amazonensis was identified by molecular test. Interventions: The patients were treated with conventional therapies for HIV infection and American tegumentary leishmaniasis. Outcomes: In co-infection, the clinical manifestations are atypical and the treatment response can be impaired. Lessons: These cases show that HIV infection impacts L. amazonensis infection and point to the relevance of identifying Leishmania species, which can lead to a better patient management.

Comparison of grain protein profiles of Brazilian cowpea (Vigna unguiculata) cultivars based on principal component analysis

引用

Food Production, Processing and Nutrition 2022年第1期4卷 172-182页

作者： Tuany camila Honaiser Gabriela Barbosa Rossi Maurisrael de Moura Rocha Ana Carolina Maisonnave Arisi Food Science and Technology Department CAL CCA UFSCFederal University of Santa CatarinaRod.Admar GonzagaFlorianópolisSanta Catarina134688034-001Brazil Embrapa Meio-Norte Caixa Postal 001TeresinaPiauí64008-780Brazil

This study aims to compare the grain protein profile of four Brazilian cowpea cultivars (BRS Aracê, BRS Itaim, BRS Pajeú, and BRS Xiquexique) by two-dimensional electrophoresis (2-DE) and principal component analysis (PCA). 2-DE efficiently separate cowpea protein profiles, showing high homogeneity among the four cultivars. In addition, the principal component analysis indicated that there is a difference in abundance of proteins among the cultivars. The cultivars BRS Aracê and BRS Xiquexique, both biofortified in iron and zinc, were separated from the cultivars BRS Itaim and BRS Pajeú. These results demonstrate that protein profiles can be used to discriminate cowpea varieties.

Antagonistic Activity, Antimicrobial Susceptibility and Potential Virulence Factors of Enterococcus faecalis

引用

Journal of Life Sciences 2015年第7期9卷 318-326页

作者： camila de souza Cameiro Norma Suely Evangelista-Barreto Carla Silva da silveira-Oliveira Irana Pain Silva Thiago Alves Santos de Oliveira Margarete Alice Fontes Saraiva Center of Agricultural Environmental and Biological Sciences (CCAAB) Federal University of Rec6ncavo da Bahia (UFRB) Cruzdas AImas Bahia 44380000 Brazil

Enterococcus faecalis isolates (87) were phenotypically and genotypically identified and subsequently subjected to the antagonism test and antimicrobial susceptibility. The lipolitic, hemolytic and DNAse activities were identified along with the genes gelE, cylL, cylS, ccf, cpd and cob that, encode virulence determinants. Thirty seven percent of isolates inhibited Listeria monocytogenes (CERELA), Listeria innocuous (CERELA), Staphylococcus aureus (ATCC25932), Lactococcus lactis (IL1403), Micrococcus luteus (ATCC10240) and Enterococcus faecalis (ATCC29212). All strains were sensitive to the ampicillin antibiotic, but 47% were resistant to at least one antimicrobial agent and 6% of isolates presented multidrug resistance. Ninety seven percent of isolates contained the gelE gene, but 77% of these isolates showed gelatinase activity. Presence of cylL and cylS genes was observed in 25% of the isolates, but only 5% presented hemolytic activity. None isolates showed lipase and DNAse activities. Eight percent of isolates contained the ccf gene and 2% showed the presence of the cpd and cob genes. The ability to inhibit pathogenic bacteria, low resistance to antibiotics and absence of virulence factors make some of Enterococcus faecalis strains characterized in the present study promising for exploitation in other applications such as probiotics in aquaculture.
