Ludmilla Santana Soares e Barros, Jana Kelly dos Santos, Maurício Mascarenhas Pedreira, Sanmily Santos Damacena, Adriana dos Santos Silva
Food and Nutrition Sciences (FNS) , 2018, DOI: 10.4236/fns.2018.96049
Abstract: Tuberculosis and the taeniasis-cysticercosis complex, typical cases of zoonosis, have great importance for public health, since they cause economic liabilities to the Brazilian beef production chain. They are actually a synonym of technical inadequateness in Good Production Practices. Both diseases have existed since ancient times and their occurrence should be controlled by basic sanitary measures. However, there is a significant neglect attitude by authorities of countries with high occurrence rates, or rather, tropical underdeveloped nations, to focus on public policies for the control and decrease of the prevalence and the occurrence of these diseases. Current review elucidates the epidemiological profile of the diseases and contributes towards the elucidation and establishment of measures ensuring control.

Abstract: Since amateur fishing in fishponds has been on the increase in Brazil, there is a great concern on the microbiological quality of fish. One hundred and thirty-eight samples were collected during the dry and rainy periods in ten fish farms. Aeromonas spp. counts and tests for sensitiveness to antimicrobials were performed, coupled to the physical and chemical analyses of water. Tests revealed that 70% of samples were contaminated by Aeromonas spp., with water averaging 2.92 Log CFU/100 mL during the rainy period and 3.16 Log CFU/100 mL during the dry one. Fish contaminated by Aeromonas spp. averaged 2.58 Log CFU/100 mL during the rainy period and 3.53 Log CFU/100 mL during the dry one. Aeromonas spp. samples were multi-resistant to 2 or 8 antimicrobials in 62.5% of the samples. Ampicillin was the antimicrobial with the highest resistance percentage rate. Results showed that fish bred in amateur fish farms constituted a health risk for the population.

Abstract: Urinary tract infection (UTI) is a frequent pathology among HTLV-I+ individuals being capable of severely compromising the kidneys and bladder. Molecular characteristics of uropathogenic Escherichia coli (UPEC) from HTLV-I+ infected individuals are unknown. UPEC isolates from HTVL-I+ individuals, with and without clinical symptoms of myelopathy, were submitted to genetic typing seeking to infer bacterial diversity and potential virulence. 71 bacterial isolates were characterized according to random amplified polymorphic DNA and phylotypes. Phylotyping classified E. coli into four phylogenetic groups: A (18.3%), B1 (16.9%), B2 (39.4%), and D (25.3%) and 8 phylotypes according to the presence of the genetic sequences chuA, yjaA and the DNA fragment TSPE4.C2: (5.6%) and + (12.6%) in phylogroup A, + (7.0%) and ++ (9.8%) in B1, +++ (32.3%) and ++ (7.0%) in B2, + (15.4%) and ++ (9.8%) in D. The B2 phylogroup was the most prevalent among HTLV associated myelopathy and asymptomatic individuals. RAPD-PCR typing revealed a high degree of bacterial polymorphism indicating a non-clonal origin. Genotypes were not found to be distributed according to clinical status or epidemiological features. Our results lead us to suggest that the neurological impairment in HTLV-I+ individuals can be a risk factor for urinary infections due E. coli which are caused by distinct bacterial lineages.

Food and Nutrition Sciences (FNS) , 2017, DOI: 10.4236/fns.2017.811075
Abstract:
Hygiene-sanitary conditions, the presence of Salmonella spp. and indicator microorganisms of chicken cuts sold on the market in the Rec?ncavo da Bahia area, are analyzed and their co-relationship with conditions of commercialization is verified. Sixty samples were collected between May and August 2016 at informal selling sites (fairs, butcher shops, abattoirs) and in supermarkets of ten municipalities of the Rec?ncavo da Bahia region. Hygiene and sanitary conditions were assessed through a check list. Total coliforms, Escherichia coli, mesophylls, psychrotrophic organisms, molds and yeast, and Salmonella spp. were counted. Results revealed statistical difference for total coliforms and Escherichia coli only, featuring greater concentration rates in fairs, butcher shops and abattoirs. Further, 31.7% of samples indicated 31.7% Salmonella spp. and 16.6% of samples failed to comply with sanitary legislation on Escherichia coli. Observational analysis demonstrated that 61.83% and 38.1% of the samples respectively on informal sites and in supermarkets did not comply with legislation and indicated a co-relationship of some variables with the growth of total coliforms, Escherichia coli and mesophylls. Pathogenic and indicator microorganisms suggest flaws in hygiene and sanitary conditions in the commercialization of chicken cuts and health risks to consumers.

Abstract: High nutritional content coupled with low cost and ease of purchase justifies the frequent use of chicken eggs. Even with technological innovations in the production, storage, and distribution of eggs, food poisoning continues to occur. Therefore, in the present study, we 1) evaluated the microbiological profile and the hygienic and sanitary quality of eggs commercialized in town fairs and markets and 2) verified whether there is any correlation between microbiological results and commercialization conditions. Thirty-six samples were collected from six municipalities in the region of Rec?ncavo from Bahia, Brazil. The hygienic and sanitary conditions were analyzed by quantifying the total coliforms, E. coli, mesophilic and psychrotrophic microorganisms, molds, and yeasts, and by the presence of Salmonella sp. The observational analysis showed that 91% and 68% of the samples in town fairs and markets, respectively, did not comply with the requirements of the current Brazilian legislation. There was no significant difference in the microbiological profile among samples from the fairs and markets. Several samples presented relevant significant values, indicating inadequate hygienic conditions and fecal contamination. Salmonella sp. was found in one sample. There was co-relationship between microorganism count and the variables “external dirt”, “external stains”, and “closeness to other products”, with high concentrations of total coliforms and E. coli in the non-conforming samples. Although no limits exist for mold and yeast counts, the presence of fungi makes the product unfit for consumption. Thus, the commercialization of eggs would benefit from more attention and supervision by the relevant authorities.

Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.414109
Abstract: This study aimed to evaluate the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of Coffea canephora aqueous extract (Cc), trigonelline (Tg) and 5-caffeoylquinic acid (5-CQA) against cariogenic microorganisms: Streptococcus parasanguinis ATCC 903 (SP), Lactobacillus rhamnosus ATCC 9595 (LR); and pathogens related to periodontal disease: Porphyromonas gingivalis ATCC 33277 (PG), Fusobacterium nucleatum ATCC 25586 (FN), Prevotella intermedia ATCC 49046 (PI) and Prevotella nigrescens ATCC 33563 (PN). Different concentrations of Cc (0.15625 to 10 mg/mL), Tg and 5-CQA (0.005 to 10.24 mg/mL) were tested. Chlorhexidine (0.05%) was used as positive control and the substances without the inoculum comprised the blank control. The Cc showed bacteriostatic action against SP (MIC = 5 mg/mL) and LR (MIC = 10 mg/mL). Tg showed bacteriostatic action against SP (MIC = 2.56 to 1.28 mg/mL), LR (MIC = 2.56 mg/mL), PG (MIC = 2.56 to 1.28 mg/mL), FN (MIC = 5.12 mg/mL), PN (MIC = 2.56 mg/mL), and PI (MIC = 2.56 to 1.28 mg/mL). Also, Tg showed bactericide properties against SP (MBC = 2.56 mg/mL), PG (MBC = 2.56 mg/mL), FN (MBC = 10.24 mg/mL), PN (MBC = 5.12 mg/mL), and PI (MBC = 2.56 mg/mL). Although 5-CQA has previously shown activity against Streptococcus mutans, in the present study, it showed no activity against all tested microorganisms. C. canephora extract only showed antibacterial activity against cariogenic microorganisms, not presenting action against periodontal pathogens. It was concluded that trigonelline presented the best effect against all pathogens tested, therefore coffee extracts with higher trigonelline content should be tested against these specific pathogens.

Abstract: This paper presents the analysis of a training practice developed in a Health Center located in the North Sanitary District of Belo Horizonte. The central aim of the practice was to promote initiatives of mobilization and political discussions among women who live in the region covered by the health center. During the meetings, discussions were produced through the background of gender relations, approaching themes as violence, women’s health, work division, women’s valorization, construction of social roles, and human rights. The practice was named as “Women’s Movement” by the women involved in one of the first meetings. The work is inspired in participant methodologies and in the comprehension of group as a device, especially when it comes to the co-construction of actions in the health field. The concepts of gender and empowerment were guidelines of the reflections and actions. The meetings took place every other week, with average duration of one and a half hour each. There were approximately 12 women in each meeting between users, psychology students, and health communitarian agents. As an articulation attempt, in two meetings a Municipal Health Counselor was present, discussing women’s role in social mobilization. The practice has been revealed as an important device of integrations, since it puts closer and produces accountability between university, health services, and community in the construction of health actions. En este artículo se presenta el análisis de una práctica realizada en un centro de salud ubicado en el Distrito Sanitario Norte de Belo Horizonte. El objetivo principal de la práctica era promover iniciativas de movilización y discusiones políticas entre las mujeres que viven en la región cubierta por el centro de salud. Durante las reuniones fueran producidas discusiones teniendo como telón de fondo las relaciones de género, ocupándonos de temas como la violencia, la salud de las mujeres, la división del trabajo, lo empoderamiento de las mujeres, la construcción de los roles sociales y los derechos humanos. La práctica fue llamada “Movimiento de Mujeres” por sus propios miembros en una de las reuniones iniciales. El trabajo se hay inspirado en las metodologías participativas y en la comprensión del grupo como dispositivo, especialmente con respecto a la co-construcción de las acciones de salud. Los conceptos de género y empoderamiento fueran organizadores de las reflexiones y de las acciones. Las reuniones se realizaron cada dos semanas, con un promedio de una hora y media. Había alrededor de 12 mujeres por encuentro, incluso usuar
