An important dairy basin located in the region of Agreste of Pernambuco, maintains the tradition in the production of milk and derivatives, having in the cream a lipid food of great sensorial appreciation. However, its artisanal production can compromise the physical-chemical and hygienic-sanitary quality. Therefore, this study aimed to evaluate the microbiological parameters and the centesimal composition of the cream produced in the Agreste of Pernambuco. Total coliforms at the mean concentration of 4.0 x 102 CFU.g-1 and thermotolerant coliforms up to 20 CFU.g-1 were found, the latter in a concentration above the limit allowed by RDC No. 12 (BRASIL, 2001). the amount of up to 10 CFU.g-1, thus proving the presence of fecal material next to the product. The presence of coagulase positive Staphylococcus and Salmonella spp. The centesimal composition of the cream showed 531.07 kcal, 39.39% humidity, 0.26 g ash, 0.92 g of carbohydrate, 1.7 g of protein, and 57.73 g of lipids. Considering the microbiological results and the centesimal composition, it is observed that the cream studied should be consumed with moderation, since besides presenting a high percentage of lipids, above the nutritional recommendation, that is up to 30%, it is unsafe as to its consumption, due to the presence of thermotolerant coliforms above the limit allowed by current sanitary legislation.

Sixty samples of chilled chicken carcasses submitted (30) and not submitted (30) to Brazilian inspection services were analyzed to investigate if inspected and non-inspected chilled carcasses represented different food safety risks in the region of Viçosa, MG, Brazil. The mean counts of indicator microorganisms (mesophilic aerobes, Enterobacteriaceae, total coliforms and Escherichia coli) of samples belonging to the inspected and non-inspected lots did not present significant differences (P>0.05). Also, no significant differences (P>0.05) were observed for the numbers of Salmonella spp. and E. coli (higher than 2log cfu g-1) between samples submitted or not to inspection. Statistical differences were observed between the two sample classes only for the numbers of mesophilic aerobes higher than 4 and 5log cfu g-1 (P<0.05). The obtained results indicated the limitations of microbiological parameters to differentiate inspected and non-inspected chilled chicken carcasses commercialized in the specific studied area.

In general, the meat contains nutrients of high biological value and susceptible to contamination by enteropathogens. One way of minimizing/eliminating this contamination is the use of food additives, in the case of meat, usually sodium sulphite. This technological resource is used to inhibit the growth of pathogenic bacteria such as Salmonella spp. and thermotolerant coliforms, mandatory parameters foreseen in sanitary legislation. Therefore, the objective of this article was to evaluate the presence of sodium sulfite and detection of Salmonella spp., total and thermotolerant coliforms in 23 samples of ground beef and 7 of fresh pork sausage, marketed in open markets and public markets of Grande Recife - PE. In a total of 30 samples analyzed, it was not detected in any presence of sodium sulphite. In the microbiological assays, also it was not detected the presence of Salmonella spp. and thermotolerant coliforms. The Total Coliforms was found in 20 meat samples (87%), at the maximum concentration of 35 MPN/g-1 and in all sausages (100%) at the concentration of 35 to 36 MPN/g-1. Although the Total Coliforms is not considered pathogenic, the presence of this indicates unsatisfactory sanitary conditions in the production, which may constitute biological risk for vulnerable groups.

Meliponine is a honey with particular characteristics; it has a high percentage of humidity, which can favor the development of microorganisms, thereby causing changes in the quality of the product. The objective of this study was to evaluate the microbiological characteristics of meliponine honey produced by different species and marketed in the State of Paraná-Brazil. The sample unit was composed of honey of Tetragonisca angustula (n = 15), Scaptotrigona bipunctata (n = 05), Melipona quadrifasciata quadrifasciata (n = 05) and Melipona bicolor schencki (n = 01). The following microbiological parameters were evaluated: counts of total and thermotolerant coliforms, fungi count and detection of Salmonella spp. Principal component analysis (PCA) was used to evaluate the possible relationships among species, locality and type of microorganism. For microorganisms of the total coliform group, 15.38% of the analyzed samples had values >3 MPN/g. The presence of thermotolerant coliforms was observed in 7.69% of the samples, all of which were T. angustula samples. For fungi counts, 100.00% of the analyzed samples had values within the established range created by the Agricultural Defense Agency of Paraná. The presence of Salmonella spp. was not observed in any of the samples evaluated. The amount of water in the honey is related to the location of the apiary and edaphoclimatic factors. Adoption of good handling practices by beekeepers is indispensable for the safety of the final product.

The study analyzed the physical-chemical and microbiological parameters carried out by the Autonomous Water and Sewage Service (AWSS) of the Municipality of Alvorada D’Oeste, Rondônia, Brazil. The parameters analyzed were: pH, turbidity, free residual chlorine, total coliforms (TC), thermotolerant coliforms (TTC) and heterotrophic bacteria. The values of hydrogen potential (pH) were obtained with a digital pH meter. The analyzes were carried out the 2013 to 2019. The turbidity and free residual chlorine values were obtained according to the method of the Practical Manual of Water Analysis of the National Health Foundation (FUNASA). To determine the microbiological parameters, PetrifilmTM plates (3MTM do Brasil Ltda) were used, following the manufacturer's guidelines. The analyzed values were compared with reference values described in Consolidation Ordinance nº. 5, of September 28, 2017, of the Ministry of Health (MS) which sets the standards for potability of water intended for human consumption. The results varied for all parameters evaluated: pH (3.11 to 8.24), turbidez (0.02 to 3,01), TC (0 to 100%), TTC (0 to 100%) and heterotrophic bacteria (85 to 100%). The values obtained for free residual chlorine were the only parameter to follow the reference values. The highest contamination for TC and heterotrophic bacteria were reported in 2019, higher the limits established in Brazilian legislation. Thus, the water was characterized as unfit for consumption and requires severe control for TC and heterotrophic bacteria.

This work aimed to evaluate the biogas production potential of swine manure (SM) under different temperatures through the use of experimental biodigesters (EB), investigating the physical, chemical and microbiological parameters of the process. The experiment consisted of three treatments a) with solid fraction separation (WSSF), b) without solid fraction separation (W-SSF) and c) solid fraction only (OSF).  The assays were performed in triplicate and submitted  to room temperature (RT) (13.36 to 23.71° C) and to controlled temperature (30.00ºC), during 28 days. The average biogas production in the EB was 390.41 ml (WSSF), 390.53 ml (W-SSF) and 400.53 ml (OSF), at RT and 393.00 ml (WSSF), 393.00 ml (W-SSF) and 390.67 ml (OSF) at 30.00ºC. The results showed that significant differences occurred in the biogas production due to the different treatments and temperatures. The highest average reduction of parameters as a function of treatment and temperature was 53.22% for total solids in WSSF (30°C), 10.73% for nitrogen in W-SSF (RT), 27.50% for phosphorus in the WSSF (TA), 63.55% for the COD in the W-SSF (TA), 99,10% for the total coliforms in the W-SSF (TA) and 99.59% for the thermotolerant coliforms in the WSSF (30°C).

Cabacinha cheese from Vale do Jequitinhonha is similar mozzarella, but in this milk is crude, being the product is stored at ambient without packaging. Besides it contributes to local income, customers may be food-poisoned. The objective of this study was to verify the physical-chemical and microbiological characteristics of samples of Cabacinha cheese produced and marketed in Vale do Jequitinhonha-MG. Samples were bought in tents (n=25), restaurants (n=4) and bakeries (n=2) located by BR 251 and BR 116 highways in the towns of Medina, Cachoeira de Pajeú and Pedra Azul. Cheeses from 17 marketplaces were purchased from the first town, 10 from the second and 4 from the third, respectively. The coliforms at 35ºC, Escherichia coli, coagulase positive Staphylococcus, lactic acid bacteria, filamentous fungi and yeasts were 1.8 x 103; 1 x 101; 4.6 x 103; 6.3 x 107 and 4.9 x 106 Colony Forming Units per gram, respectively, and Salmonella spp. are absent. The chemical characteristics mean was 26.47% of protein, 27.69% of fat, 4.34% of minerals, 36.23% of moisture, 843.66 mg/100g of sodium and pH of 5.14. This is the first paper that describes microbiological and chemical characteristics of Cabacinha cheese from Vale do Jequitinhonha. The absence of regulations for microbiological parameters may put the health of consumers at risk.

The wastewater plant of Rome airport, which receives all the sewage from the airport as well as the cess from aeroplanes, was analysed for microbiological parameters. From the bacteriological point of view, in the water and sludge samples the densities of the faecal indicator of pollution and the presence of Salmonella spp and Vibrio cholerae as bacteriological pathogens were determined. At the same time, samples were analysed for the presence of enteric viruses and phages. Overall, the mean reduction of the faecal coliforms was 96%, E. coli 92% and faecal streptococci 99%. Salmonella spp was identified in all but one of the final effluents and V. cholerae in 2/10. Enteric viruses were identified in all but one of the raw waters and in three samples of final effluent. Bacteriophages (somatic coliphage, F-plus phage and B40-8), were found in all the samples but irregularly. Phages and enteric viruses were also found in the prefilter membranes used for prefiltering the raw water samples.

Gelchromatography column scanning has been used to study the fractions of reduced hydrolyzed 99mTc, 99mTc-pertechnetate and 99mTc-chelate in a 99mTc-glucoheptonate (GH) preparation. A stable high labelling yield of 99mTc-GH complex in the radiopharmaceutical has been obtained with a concentration of 40-50 mg of glucoheptonic acid-calcium salt and not less than 0.45 mg of SnCl2 2 H2O at an optimal pH between 6.5 and 7.0. The stability of the complex has been found significantly affected when sodium hydroxide solution was used for the pH adjustment. However, an alternative procedure for final pH adjustment of the preparation has been investigated providing a stable complex for the usual period of time prior to the injection. The organ distribution and the blood clearance data of 99mTc-GH in rabbits were relatively similar to those reported earlier. The mean concentration of the radiopharmaceutical in both kidneys has been studied in normal subjects for one hour with a scintillation camera and the results were satisfactory.

ABSTRACT Progesterone was determined and identified in human peripheral blood during the preovulatory period of the menstrual cycle, by combined isotope derivative and recrystallization analysis. The mean concentration of progesterone in 1.095 ml of plasma obtained 9 days before ovulation was 0.084 μg/100 ml. However, the mean concentration of progesterone in 1.122 ml of plasma obtained 4 days before ovulation was 0.279 μg/100 ml. These data demonstrate a source of progesterone secretion other than the corpus luteum. The higher plasma-progesterone concentration 4 days before ovulation may indicate progesterone secretion of the ripening Graafian follicle of the ovary.
