Resumo: Introduction: Cronobacter spp. is a bacterial genus that includes 7 species; Cronobacter sakazakii is the clinical specie that is the most reported and associated with meningitis and septicemia in infants. Given that it is transmitted by powdered infant formula (PIF), the WHO recommends that this product be free of Cronobacter, whereas the Chilean Food Sanitary Regulation (RSA) does not consider it. Objective: To assess the risk of C. sakazakii in PIF for consumption by infants. Methodology: A total of 72 PIF samples were analyzed using three brands originating from three countries. Aerobic plate count (APC), Enterobacteriaceae (ENT), and most probable number (MPN) were performed using the methodology described by Puch and Ito (2001). Cronobacter differential agar was used to isolate strains (DFI, Oxoid, England), and the ID32E biochemical kit (Biomeriux, France) was used for phenotyping. The pathogen was identified and genotyped by multilocus sequence typing (MLST) based on the criteria found at http://www.pubmlst.org/cronobacter. Results: Median APC for step 1 and preterm PIF was 300 CFU/g (10-36 000) and 650 CFU (70-30 000), respectively and was higher in Chilean PIF (p=0.016). There were no significant differences for type, country or PIF brand in 75 CFU/g (10-36 000) and 200 CFU/g (10-1 000) ETN (p>0.05). Two strains from two different lots with characteristic strains in DFI agar were identified as C. sakazakii with 0.23 and 2.3 MPN/g. In addition, Franconibacter helveticus, specie closely related to Cronobacter spp, was found in two other strains. Conclusions: The prevalence of Cronobacter sakazakii in all the samples was 2.7% isolated only in PIFs manufactured in Chile. The absence of Cronobacter spp in 25 g must be included in the Chilean RSA.

Introducción: Cronobacter spp es un género bacteriano con 7 especies, siendo C. sakazakii la especie clínica más reportada y asociada a meningitis y septicemia en lactantes. Es transmitida por leche en polvo (LP) por lo que la OMS recomienda su ausencia en este producto. En Chile, el reglamento sanitario de los alimentos (RSA) no lo considera. Objetivo: Evaluar el riesgo por Cronobacter sakazakii en LP destinadas al consumo de lactantes. Metodología: Se analizaron 72 muestras de LP de 3 marcas y 3 países. El recuento de bacterias mesófilas (RAM), Enterobacteriaceae (ENT) y número más probable (NMP) se realizó con la metodología de Puch and Ito (2001). Se utilizó agar diferencial Cronobacter para aislamiento (DFI, Oxoid, England) y kit bioquímico ID32E (Biomeriux, Francia) para fenotipo. El patógeno fue identificado y genotipificado por multilocus sequence typing (MLST) utilizando criterios de http://www.pubmlst.org/cronobacter. Resultados: La medianas de RAM para LP etapa 1 y prematuros fueron 300 UFC/g (10-36 000) y 650 UFC/g (70-30 000), siendo mayor en las muestras de Chile (p=0,016). Para ENT de 75 UFC/g (10-1 060) y 200 UFC/g (30-1 000), no existiendo diferencias significativas por tipo, país o marca de LP (p>0,05). Dos cepas de 2 lotes diferentes características en agar DFI se identificaron como C. sakazaki con 0,23 y 2,3 NMP/g. Además de Franconibacter helveticus en otras 2 cepas, especie relacionada estrechamente con Cronobacter spp. Conclusiones: La prevalencia de C. sakazakii en todas las muestras fue de 2,7% y aisló sólo en LP de elaborados en Chile. La ausencia de Cronobacter spp en 25 g debe ser incorporado en el RSA de Chile.

Resumo: ABSTRACT Objectives This cross-sectional study compared the frequency of oral periodontopathogens and H. pylori in the mouths and stomachs of obese individuals with or without periodontitis submitted to bariatric surgery. Material and Methods One hundred and fifty-four men and women aged 18-65 were conveniently distributed into four groups. Two groups were composed of individuals who underwent bariatric surgery with (BP) (n=40) and without (BNP) (n=39) periodontitis and two obese control groups with (CP) (n=35) and without (CNP) (n=40) periodontitis. The oral pathogens Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Parvimonas micra, Treponema denticola, Tannerella forsythia, Campylobacter rectus, and Helicobacter pylori were detected by a polymerase chain reaction technique using saliva, tongue and stomach biopsy samples. Results Statistical analysis demonstrated that periodontopathogens were highly frequent in the mouth (up to 91.4%). In the bariatric surgically treated group, orally, P. gingivalis, T. denticola and T. forsythia were more frequent in periodontitis, while C. rectus was more frequent in non-periodontitis subjects. Stomach biopsies also revealed the high frequency of five oral species in both candidates for bariatric surgery (91.6%) and the bariatric (83.3%) groups. H. pylori was frequently detected in the mouth (50.0%) and stomach (83.3%). In the stomach, oral species and H. pylori appeared in lower frequency in the bariatric group. Conclusions Obese individuals showed high frequencies of periodontopathogens and H. pylori in their mouths and stomachs. Bariatric surgery showed an inverse microbial effect on oral and stomach environments by revealing higher oral and lower stomach bacterial frequencies.

Título: Intereactions between doripenem and clavulanate ­ Application of minimal inhibitory concentration analysis and cytometry flow for bactericidal studies
Fonte: Electron. j. biotechnol;32:41-46, Mar. 2018. tab, ilus, graf.
Idioma: en.
Projeto: National Science Centre (Poland).
Resumo: Background: In view of the current low efficacy of bacterial infection treatment the common trend towards searching for antibiotic systems exhibiting synergistic action is well justified. Among carbapenem analogues a particularly interesting option is provided by combinations of clavulanic acid with meropenem, which have proven to be especially effective. Results: Determination of the minimal inhibitory concentration (MIC) along with the method based on flow cytometry constitutes an important tool in the identification of bacterial sensitivity to active substances. Within this study the inhibitory effect of doripenem, clavulanic acid and the doripenem-clavulanate acid system was analyzed in relation to such bacteria as Salmonella enteritidis, Salmonella typhimurium, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Clostridium butyricum and Clostridium pasteurianum, Acinetobacter baumannii, Enterobacter aerogenes. The lowest MIC, amounting to 0.03 µg/mL, was observed for the doripenem-clavulanate acid system in the case of E. coli ATCC 25922. In turn, the lowest MIC for doripenem applied alone was recorded for K. pneumoniae ATCC 31488, for which it was 0.1 µg/mL. The strain which proved to be most resistant both to doripenem and the doripenem-clavulanate acid system, was A. baumannii, with MIC of 32 µg/mL (clinical isolate) and 16 µg/mL (reference strain). Cytometric analysis for P. aeruginosa ATCC 27853 and S. aureus ATCC 25923 showed changes in cells following exposure to limiting concentrations of the active substance. Conclusions: Analysis of MIC supplies important information concerning microbial sensitivity to active substances, mainly in terms of limiting concentrations causing mortality or vitality of the tested species, which is essential when selecting appropriate antibiotic therapy.

Resumo: Microbial mats are horizontally stratified microbial communities, exhibiting a structure defined by physiochemical gradients, which models microbial diversity, physiological activities, and their dynamics as a whole system. These ecosystems are commonly associated with aquatic habitats, including hot springs, hypersaline ponds, and intertidal coastal zones and oligotrophic environments, all of them harbour phototrophic mats and other environments such as acidic hot springs or acid mine drainage harbour non-photosynthetic mats. This review analyses the complex structure, diversity, and interactions between the microorganisms that form the framework of different types of microbial mats located around the globe. Furthermore, the many tools that allow studying microbial mats in depth and their potential biotechnological applications are discussed.

Resumo: Background: Microbial Fuel Cell (MFC) technology is used in various applications such as wastewater treatment with the production of electrical energy. The objective of this study was to estimate the biodepuration of oils and fats, the elimination of blue dye brl and bioelectro-characterization in MFCs with Chlorella vulgaris and bacterial community. Results: The operation of MFCs at 32 d showed an increase in bioelectrogenic activity (from 23.17 to 327.67 mW/m2 ) and in the potential (from 200 to 954 mV), with biodepuration of fats and oils (95%) in the microalgal cathode, and a removal of the chemical oxygen demand COD (anode, 71%, cathode, 78.6%) and the blue dye brl (73%) at the anode, here biofilms were formed by the bacterial community consisting of Actinobacteria and Deltaproteobacteria. Conclusions: These findings suggest that MFCs with C. vulgaris and bacterial community have a simultaneous efficiency in the production of bioelectricity and bioremediation processes, becoming an important source of bioenergy in the future.

Projeto: Mauritius Research Council for funding the project; . LANDRACE.
Resumo: Background: The past years have witnessed a growing number of researches in biofilm forming communities due to their environmental and maritime industrial implications. To gain a better understanding of the early bacterial biofilm community, microfiber nets were used as artificial substrates and incubated for a period of 24 h in Mauritian coastal waters. Next-generation sequencing technologies were employed as a tool for identification of early bacterial communities. Different genes associated with quorum sensing and cell motility were further investigated. Results: Proteobacteria were identified as the predominant bacterial microorganisms in the biofilm within the 24 h incubation, of which members affiliated to Gammaproteobacteria, Alphaproteobacteria and Betaproteobacteria were among the most abundant classes. The biofilm community patterns were also driven by phyla such as Firmicutes, Bacteroidetes, Chloroflexi, Actinobacteria and Verrucomicrobia. The functional analysis based on KEGG classification indicated high activities in carbohydrate, lipid and amino acids metabolism. Different genes encoding for luxI, lasI, agrC, flhA, cheA and cheB showed the involvement of microbial members in quorum sensing and cell motility. Conclusion: This study provides both an insight on the early bacterial biofilm forming community and the genes involved in quorum sensing and bacterial cell motility.

Título: Escherichia coli GutM4 produces 2, 5-diketopiperazines and inhibits human pathogens in vitro
Fonte: Electron. j. biotechnol;28:35-40, July. 2017. ilus, tab.
Idioma: en.
Projeto: Shanxi Scholarship Council of China.
Resumo: Background: It has been a very common practice to use probiotics or their metabolites as alternative antimicrobial strategies for the treatment and prevention of infections as rampant and indiscriminate use of antibiotics causes the development of antibiotic-resistant pathogens. The objective of this study was to select a potential antimicrobial probiotic strain of Escherichia coli from the human gastrointestinal tract and investigate the production of diketopiperazines that contribute to the antimicrobial activity. Results: E. coli GutM4 was isolated from the feces of a healthy adult. E. coli GutM4 showed significant antagonistic activity against 10 indicator pathogens, and this activity was no less than that of the reference strain E. coli Nissle 1917 against eight of the indicator pathogens. Moreover, E. coli GutM4 produced antagonistic substances containing trypsin-targeted peptide bonds because the inhibitory effects of E. coli GutM4 supernatant significantly decreased upon treatment with trypsin. Consistent with the antagonistic activity and peptide compounds of E. coli GutM4, 14 2,5-diketopiperazines were isolated from the fermented broth of E. coli GutM4, including 12 cyclo(Pro-Phe), 3 cyclo(Pro-Tyr), and 5 cyclo(4-hydroxyl-Pro-Leu), which are reported to have antipathogenic activity. Conclusion: E. coli GutM4 produces 2,5-diketopiperazines that are partly involved in antagonistic action against human pathogens in vitro.

El objetivo de este estudio ha sido realizar un seguimiento de la etiología de las infecciones urinarias, de adquisición comunitaria, de la resistencia a los antimicrobianos de primera línea y la presencia de Betalactamasas de Espectro Extendido en bacilos gram negativos (BLEE). MATERIAL Y MÉTODOS: El estudio fue realizado entre enero de 2011 y diciembre de 2015 con datos del Laboratorio Microbiología del Hospital de Clínicas de la Universidad Nacional de Asunción. RESULTADOS: Se obtuvieron 1957 uropatógenos en mujeres. Escherichia coli fue el gérmen más frecuentemente aislado (57%), seguido de Klebsiella pneumoniae (11%) y Streptococcus agalactiae, Staphylococcus saprophyticus y Proteus mirabilis (2%). El promedio de resistencia de Escherichia coli fue para trimetoprim-sulfametoxazol 43 %, ciprofloxacina 32%, ampicilina-sulbactam 32%, cefotaxima 13%, piperacilina tazobactam 8%, nitrofurantoína 2% y meropenem no presentaba resistencia alguna en este lapso. El 11% de las cepas de Escherichia coli y el 30 % de Klebsiella pneumoniae produjo betalactamasas de espectro extendido. CONCLUSIONES: Las tasas de resistencia y de resistencias cruzadas que se evidencian en este estudio representan un grave problema que obliga a evaluar permanentemente el tratamiento empírico de las infecciones urinarias en nuestro hospital

INTRODUCTION: The growing resistance rates of urinary pathogens represent a serious problem. The aim of this study was to analyze the etiology of community-acquired urinary tract infections, their first-line antimicrobial resistance and the presence of extended-spectrum beta-lactamases (ESBL) in gram negative bacilli. METHODS: The study was conducted between January 2011 and December 2015 using data from the Microbiology Laboratory at the teaching hospital Hospital de Clínicas, which belongs to the National University of Asunción. RESULTS: A total of 1957 urinary pathogens were found in women. Escherichia coli was the most commonly isolated bacterium (57%), followed by Klebsiella pneumoniae (11%) and Streptococcus agalactiae (2%), Staphylococcus saprophyticus (2%) and Proteus mirabilis (2%). The resistance rates of Escherichia coliwere the following: to trimetoprim-sulfametoxazol, 43%; to ciprofloxacin, 32%; to ampicilin/sulbactam, 32%; to cefotaxime, 13 %; to piperacillin/tazobactam, 8%; nitrofurantoin, 2%, whereas it did not show resistance to meropenem during this period. Extended-spectrum beta-lactamases were produced by 11% of the E. coliisolates and 30% of the Klebsiella pneumoniae isolates. CONCLUSIONS: The resistance and cross-resistance rates found in this study pose a serious problem which compels the continuous assessment of the empirical therapy for urinary tract infections at this hospital

Resumo: Bacillus cereus group includes not pathogenic and high pathogenic species. They are considered as a risk to public health due to foodborne diseases and as an important cause of economic losses to industries due to production of spoilage enzymes. Some researches have been performed in order to assess the possible factors that contribute to put public health into risk because of consumption of food contaminated with viable cells or toxins which have complex mechanisms of production. The control of these bacteria in food is difficult because they are resistant to several processes used in industries. Thus, in this way, this review focused on highlighting the risk due to toxins production by bacteria from B. cereus group in food and the consequences for food safety and dairy industries.(AU)

Diversas espécies fazem parte do grupo de Bacillus cereus, desde algumas apatogênicas até outras com alta patogenicidade. Consistem em risco à saúde pública decorrentes de toxinfecções alimentares, além de causarem importantes perdas econômicas para as indústrias em virtude da produção de enzimas deteriorantes. O controle da contaminação em alimentos por esses micro-organismos é difícil, visto que são resistentes a vários tratamentos utilizados pelas indústrias. Assim, diante do exposto, esta revisão objetivou fornecer informações em relação aos aspectos genéticos desse grupo de bactérias e seus mecanismos de produção de toxinas, além de ressaltar a importância e as novas estratégias de controle para as companhias alimentícias e de laticínios.(AU)
