    Witches’ broom disease (WBD), caused by the fungus Moniliophthora perniciosa, is one of the main diseases in cocoa (Theobroma cacao) and has caused severe economic losses. Integrated disease management has been the focus for its control and therefore, the identification of new inducers of plant resistance is desirable. Thus, the goal of this work was to evaluate two potential inducers of resistance against WBD. A phosphorylated mannan oligosaccharide-based product (PMO) and acibenzolar S-methyl (ASM) were tested on M. perniciosa inoculated seedlings and in field experiments and showed a reduction on the incidence of WBD. The expression of two defense-related expressed sequence tags (ESTs) in cocoa, coding for peroxidase (Pox) and chitinase (Chi), were accessed by qPCR. Both products induced the expression of the Pox defense-related EST. In general, ASM induced the expression of chitinase (Chi) and peroxidase (Pox) in earlier time-points than PMO. However, PMO provided long-lasting and higher levels of expression. Chi expression was triggered in the time-points succeeding the spraying but was very low. On the other hand, peaks of Pox transcripts were detected in later time-points for both inducers. ASM and PMO modes of action might be explained, at least partially, by the overexpression of defense-related ESTs.Keywords: Cocoa, witches’ broom disease, disease control, peroxidase, chitinase, induced resistance, elicitors, quantitative reverse transcriptase PCR (qRT-PCR)African Journal of Biotechnology Vol. 12(12), pp. 1311-131

    This study aimed to evaluate the effect of inoculation with lyophilised and/or activated Lactobacillus buchneri on lactic acid bacteria populations in corn silage. Experimental treatments consisted of corn silage without additives or silage with the inoculants of L. buchneri (1 x 105 cfu/g) applied according to the manufacturer’s recommendations (1 g/tonne fodder) in the forms of the lyophilised inoculant and pre-activated inoculant. Purified isolates from corn silage with and without the inoculant were identified, and 93% of the isolates corresponded to the lactic acid bacteria of the species Lactobacillus plantarum. Among the isolates, no bacteria of the species L. buchneri were detected. The application of lyophilised or activated L. buchneri improved the microbiological profile and reduced ethanol production in corn silage, even without being identified among the isolates captured 70 days after ensilage. Highlights: Lactic acid bacteria showed greater development at 7 days of fermentation. Lactobacillus plantarum predominated at 70 days, representing 93% of the total LAB population. Lactobacillus buchneri improved its microbiological profile with decreased ethanol production.This study aimed to evaluate the effect of inoculation with lyophilised and/or activated Lactobacillus buchneri on lactic acid bacteria populations in corn silage.

All rights reserved.This study aimed to evaluate the influence of bareback sexually explicit media (SEM) consumption on anal sex without a condom by men who have sex with men (MSM). To this end, a page was created on the Facebook® social network with a link that directed interested parties to a questionnaire. Cisgender men, aged 18 years and over, who had sex with other men in the last 12 months, were included. Data were collected in 2017 and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. A total of 2,248 MSM participated in the research, with a mean age of 24.4 years and a mean number of 3.9 partners in the last 30 days. Having multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), preferring movies with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), considering this practice a fetish and realizing it (ORa: 3.52; 95% CI 2.3-5.4), having casual partnerships (ORa: 1.8; 95% CI 1.5-1.9) and being aware of the partner’s negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the likelihood of engaging in anal sex without a condom. Thus, we found an association between the consumption of bareback SEM and sex without a condom among MSM.

    The aim of this study was to evaluate the influence of sexually explicit media (MSE) consumption of the "bareback" type in the practice of anal sex without a condom by men who have sex with men (MSM). To this end, a Facebook® page was created, with a link that directed participants to the study questionnaire. Users who identified themselves as cisgendered men, aged 18 or over and who had sex with another man in the 12 months prior to the survey were included. Data were collected in 2017 across Brazil and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. 2248 MSM participated in the research, with a mean age of 24.4 years. Most were single (69.1%), with casual sexual partner (68.9%) and an average of 3.9 partners in the last 30 days. Have multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), prefer films with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), judge this practice a fetish and perform it (ORa: 3.52; 95% CI 2.3-5.4), have casual partnership (ORa: 1.8; 95% CI 1.5-1.9) and awareness of the partner's negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the chances of engaging in anal sex without a condom.

    Causada pelo Mycobacterium tuberculosis, a tuberculose é uma doença infecciosa e transmissível que afeta prioritariamente os pulmões, embora possa acometer outros órgãos. O tratamento da TB em pessoas vivendo com HIV (PVHIV) segue as mesmas recomendações para os não infectados. Objetivou-se explanar o conhecimento vivenciado a partir da utilização da SAE a um paciente com TB-HIV. Trata-se de um estudo descritivo do tipo relato de experiência desenvolvido em um hospital universitário da capital do Pará. O sujeito do estudo foi selecionado ao acaso, os dados coletados, analisados e posteriormente elencados os diagnósticos de enfermagem, implementadas as intervenções necessárias e verificado os resultados esperados, utilizando a taxonomia NANDA, NIC e NOC. Após identificação dos problemas, foram priorizados 4 diagnósticos de enfermagem e elaborou-se o plano de cuidados para cada um deles, evidenciando os resultados a serem alcançados por meio das intervenções. Sistematizar a assistência de enfermagem é, antes de tudo, oferecer ao paciente/cliente uma assistência de enfermagem determinada em lei, que possa garantir a biossegurança e a continuidade do cuidado

    The occurrence of antimicrobial residues and antimicrobial resistance genes in urban drinking water and sewage in Southern Brazil

    Get PDF
    Antimicrobial resistance (AMR) is currently discussed as an important issue worldwide, and the presence of antimicrobial residues (ARs) and antimicrobial resistance genes (ARGs) in the environment, especially in the water sources, is a challenge for public health. This study was conducted to evaluate the occurrence and diversity of AR and ARG in water sources from an urban center, in Southern Brazil. A total of thirty-two water samples from drinking water treatment plants (24) and sewage systems (8) were collected during two annual samplings, winter and summer. The PCR was performed by 18 ARGs, and the detection of 47 ARs was performed by LC–MS/MS. All sewage samples presented carbapenemases, ESBL, and mcr-1 genes as well as quinolones and sulfamethoxazole residues. In drinking water, we just detected blaTEM and tetB genes and doxycycline residues in samples before treatment. This study provides data about AR and ARG in drinking water and sewage systems showing that these sources are important reservoirs of both. The limited effectiveness of wastewater treatment processes to remove mainly AR demonstrates the need to implement better protocols of disinfection, in order to limit the spread of AMR in the environment

    We evaluated the effects of urea addition on gas and effluent losses, fermentation profile, microbial populations, aerobic stability and chemical composition of corn silages. A completely randomised design with five levels of urea (0, 0.5, 1.0, 1.5, and 2.0% based on dry matter) and five replicates was used. A decreasing linear effect of urea levels on effluent losses in corn silages was observed. In parallel, an increasing linear effect of urea levels on pH, increasing from 3.49 to 4.12 in silages without urea in relation to silages with the maximum urea level, was also observed. Urea addition improved the aerobic stability of the silages, with 62 h for the silages without urea and from 90 to >96 h for the silages with urea. Based on the results of the principal components, two groups (I and II) could be distinguished. The most discriminating variables in group I were dry matter (-0.9), pH (-1.2) and lactic acid bacteria (-0.9), while in group II, effluent losses (1.0), ethanol (1.0), acetic acid (0.8) and gas losses (0.8) were most important. The use of urea at inclusion levels of around 2% in corn silage reduced gas losses, improved the nutritive value and promote the aerobic stability of silages
