1. Qual é o perfil de resistência antimicrobiana ambulatorial às fluoroquinolonas em casos de cistite não complicada causada por Escherichia coli no Brasil?
Há carência de estudos de qualidade aplicáveis à Atenção Primária à Saúde sobre o tema no Brasil. Os principais estudos utilizam amostras de urina de pacientes atendidos em serviços de média e alta complexidade, o que pode introduzir importantes vieses no trabalho, prejudicando o grau de generalização dos resultados para os pacientes atendido

2. Temporal trend in early sepsis in a very low birth weight infants' cohort: an opportunity for a rational antimicrobial use
Abstract Objective This study aimed to evaluate annual trends of early neonatal sepsis and antimicrobial use in very low birth weight infants for 12 years, as well as to identify microbiological agents, antimicrobial sensitivity profiles, and association with early neonatal death. Method This was a retrospective cohort study including 1254 very low birth w

3. Synthesis, Hypoglycemic Effect, Antimicrobial and Molecular Docking Studies of Organotin(IV) Complexes Derived From N-Phthalimido β-Amino Acid Derivatives
N-Phthalimido β-amino acid derivatives, 3-phthalimido-3(2-hydroxyphenyl) propanoic acid (P2HPA) and 3-phthalimido-3(2-nitrophenyl) propanoic acid (P2NPA) with new series of di- and triorganotin(IV) complexes (1-12) have been designed and synthesized. All the ligands and organotin(IV) complexes were characterized by elemental analysis, Fourier transform infr

4. Complementary Performance of Organoselenides and Organotellurides as Antimicrobials Agents
Fungi and bacteria are well-known pathogens for plants, fruits, and animals, including humans. In this context, the prospection of antimicrobial agents is crucial to provide new alternatives for the treatment of microbial diseases. Hence, selenium- and tellurium-containing compounds are underexploited and herein, antimicrobial activity of several organochalc

5. Alternative source of probiotics for lactose intolerance and vegan individuals: sugary kefir
Abstract In this review, we aimed to explain general information about sugary kefir, microbial diversity, production process and potential health effects. Although sugary kefir has been known for many years, it has not been studied much. Studies have shown that sugary kefir has a similar microbial diversity compared to traditional milk kefir and therefore ma

6. CONSTITUENTS FROM ROOTS OF Maytenus distichophylla, ANTIMICROBIAL ACTIVITY AND TOXICITY FOR CELLS AND Caenorhabditis elegans
Maytenus distichophylla is a medicinal species used in Northeast of Brazil. The hexane (HE), chloroform (CE), ethyl acetate (EAE) and methanol (ME) extracts and compounds from its roots were evaluated for their protective activity against Staphylococcus aureus and Candida albicans. The cytotoxicity for chronic myeloid leukemia (K562), acute monocytic leukemi

7. Activity of ceftolozane-tazobactam and comparators against gram-negative bacilli: Results from the study for monitoring antimicrobial resistance trends (SMART – Brazil; 2016–2017)
Abstract Multi-drug resistant Gram-negative bacilli (GNB) have been reported as cause of serious hospital-acquired infections worldwide. The aim of this study was to investigate the in vitro activity of ceftolozane-tazobactam compared to other agents against GNB isolated from patients admitted to Brazilian medical centers between the years 2016 and 2017. Pre

8. Impact of whey protein isolate coatings containing different antimicrobial agents on sliced bologna-type sausage during refrigerated storage
Abstract In this study, we aimed to determine the possibility of using the edible whey protein isolates coatings containing different antimicrobial agents on the bologna-type sausage slices and the inactivation effects of these coatings against Listeria innocua. For this purpose, edible whey protein isolates (WPI) coatings were prepared to contain essential

9. SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF NEW Cu (II), Co (II) AND Sn (II) COMPLEXES WITH THE SODIUM HYDROTRIS(2-MERCAPTOTHIAZOLYL)BORATE LIGAND
The emergence of antibiotic resistance among microbial pathogens is a serious public health problem, resulting in a constant need of discovering new antibiotics. For this purpose, we synthetized and determined the antimicrobial activity of copper (Cu), cobalt (Co), and tin (Sn) complexes coordinated with scorpionate ligand in a tridentate mode against microo

12. ENDOPHYTIC FUNGI COMMUNITY IN Eremanthus erythropappus TREE FROM ANTHROPOGENIC AND NATURAL AREAS OF MINAS GERAIS
ABSTRACT It is know that many plants live in symbiosis with microorganisms that can be found on their interior, the endophytes. Environment and tissue type are modulating factors of this community, in which most of these microorganisms produce important antimicrobial molecules and they may be powerful biocontrol agents in agriculture. Thus, the aim of this s
