1. Economic feasibility of Gluconacetobacter diazotrophicus in carrot cultivation
ABSTRACT The inclusion of more sustainable alternatives such as bacterial inoculants is a viable option for the competitiveness of vegetable crops in tropical countries such as Colombia. The economic feasibility of a bacterial suspension of G. diazotrophicus applied to the carrot crop was determined. The native isolate G. diazotrophicus GIBI029 was evaluated

2. Streptococcus gallolyticus Bacteremia Detected in Apheresis Platelets and Its Link to Colonic Neoplasms
Abstract Introduction Streptococcus gallolyticus belongs to theStreptococcus bovis complex, and it is a common bacterium colonizing the gastrointestinal tract. Its presence in the blood may suggest an underlying pathology such as a colonic neoplasm. We report herein a case of S. bovis bacteremia in an apheresis platelet donor, review similar cases in the li

3. In vitro selection of autochthonous bacterium with probiotic potential for the neotropical fish piauçu Megaleporinus microcephalus
RESUMO O presente estudo visou isolar, identificar e aplicar testes in vitro em bactérias com potencial probiótico, autóctones, isoladas de 15 espécimes saudáveis de Megaleporinus macrocephalus. As cepas foram selecionadas do trato intestinal dos peixes e inoculadas em placas de Petri contendo Man Rogosa Sharped Agar (MRS), por 48 horas, a 35ºC. Foram

4. Antibacterial Profile in vitro and in vivo of New 1,4-Naphthoquinones Tethered to 1,2,3-1H-Triazoles Against the Planktonic Growth of Streptococcus mutans
The cariogenic processes are mainly caused by the bacterium Streptococcus mutans (S. mutans) and consist of the demineralization of the tooth that occurs when the acid production overcomes the natural repair or if a problem occurs in the last one. In this work, we performed the synthesis of twenty-one 1,4-naphthoquinones tethered to 1,2,3-1H-triazoles (8a-8k

5. High-frequency devices effect in vitro: promissing approach in the treatment of acne vulgaris?
Abstract Background: Acne vulgaris is an inflammatory skin disorder leading to an impairment of quality of life and is therefore not only a cosmetic issue. Its pathogenesis is multifactorial - of particular importance is the colonization with the bacterium Propionibacterium acnes. A wide range of different treatment options exists including topical and syst

6. Diagnosis of cutaneous tuberculosis (lymph node scrofuloderma) using the Xpert MTB/RIF® method,
Abstract Cutaneous tuberculosis is a rare infection that is difficult to diagnose, because it shows less sensitivity and specificity in classic complementary exams when compared with the pulmonary form. The Xpert MTB/RIF® method offers an early diagnosis that identifies the DNA of Mycobacterium tuberculosis and the main mutations that give the bacterium res

7. Isolation, characterisation and continuous culture of Lactobacillus spp. and its potential use for lactic acid production from whey
Abstract Bioprospecting of microorganisms with the potential of exploiting agro-industrial wastes is an active field of biotechnological research. In this study, we aimed to isolate a microorganism adapted to the dairy matrix with specific characteristics to produce lactic acid from dairy industry wastes, such as whey. Whey was collected from the agricultura

11. Pumilacidins A-E from Sediment-Derived Bacterium Bacillus sp. 4040 an Their Antimicrobial Activity Evaluation
Marine strains of Bacillus are known to produce secondary metabolites different from that accumulated by their terrestrial counterparts, for example, lipopeptides such as surfactins, iturins and fengycins, which exhibit a variety of biological activities. Another important class of lipopeptides are pumilacidins, identified specially from Bacillus pumilus str
