ANÁLISE MICROBIOLÓGICA da CARNE DE JACARÉ do PANTANAL (Caiman crocodilus yacare)

O objetivo deste estudo foi realizar o levantamento das características microbiológicas da carne do jacaré, através da detecção e/ou enumeração dos microrganismos mais comumente encontrados na carne. Pela inexistência de padrões na legislação brasileira para a carne de jacaré, os resultados foram comparados com os padrões microbiológicos existentes para carne bovina e pescado. Encontrou-se a presença de S. aureus e de Salmonella sp, resultados estes considerados insatisfatórios, o que nos permitiu, classificar o produto como impróprio para o consumo. O trabalho sugere também, procedimentos para evitar e/ou minimizar a presença desses microrganismos indesejáveis na carne.

Fezes de galinhas poedeiras na alimentação de ruminantes análises microbiológicas

The objectives of the present study were: to evaluate the variation in total number of microorganisms in laying hen fecal samples and to identify the pathogenic microorganisms possibly present such as Staphylococcus aureus, Salmonella sp., Clostridium botulinum, C chauvoei, Campylobacter sp., Escherichia coli, and Corynebacterium sp. The experiment was conducted at the School of Agrarian and Veterinarian Sciences of Jaboticabal, - UNESP. Fecal samples were collected from the aviary. A fully randomized experimental design was used with 7 treatments and 4 replications, for a total of 28 samples. A decrease in total number of microorganisms was detected when treatment T0 (zero days of storage) was compared with treatment T6 (42 days of storage), with oscillations in numbers being observed during this period of time. Pathogenic bacteria such as Clostridium noyvi, C perfringens, C sordelli, C septicum and C noyvi type B were detected, as well as non-pathogenic bacteria such as Bacillus sp. and Staphylococcus epidermidis.

Microbiological analyses of poultry litter used for ruminant feeding

The aims of this study were to estimate the changes in total bacterial counts (TBC) in poultry litter samples, consisting of rice hulls, after storage, and to identify pathogenic bacteria. For the countings Plate Count agar (Difco) was used. Enrichment and selective media such as blood agar, MacConkey, Baird Parker, brain and heart agar, and egg yolk solid media, and cooked meat and brain and heart infusion, incubated under aerobic or anaerobic conditions were used to isolate Staphylococcus aureus, Salmonella sp, Clostridium perfringens, C. botulinum, C. chauvoei, Campylobacter sp, Escherichia coli, and Corynebacterium sp. Litter samples were collected from the houses of the Veterinary School experimental aviary. A fully randomized experimental design was used with four treatments and four replications, for a total of 16 samples. A decrease in TBC was detected when treatment T1 (zero days of storage) was compared with treatments T2 (14 days of storage). on the other hand the treatments T3 (28 days of storage) and T4 (42 days of storage) presented significantly superior counting in relation to treatment T1. Some pathogenic bacteria of Enterobacteriaceae such as Escherichia coil, Proteus, Arizona, Providencia, Edwardsiella, as well as Staphylococcus aureus, S. epidermidis, different species of genus Clostridium as C. perfringens, C. sordelli, C. chauvoei, C. tetani and C. novyi as well as some strains of Corynebacterium pyogenes were isolated.

Antimicrobial activity of the essential oils of some spice herbs

Essential oils were obtained from fennel seeds, dill, cumin and coriander. Their antimicrobial activity was tested on isolated clinical specimens of patients treated at the University Hospital of the School of Medicine of Botucatu, SP, UNESP. Microorganisms were grown in BHI (Brain Heart Infusion/Oxoid) at 37oC/18 hours and resuspended in 0,5 Mac Farland's Standard (1,5 x 108 CFU/mL). The diffusion method was performed, putting 10 μl of the essential oils on paper disks (6mm of diameter) (Blank Disks/CECON) at 37oC/24 hours. After this period, the disks were put on plates containing Mueller Hinton Agar (Oxoid) and inoculated with the microorganisms. After 48 hours at 37oC, inhibitory zones were measured (mm) for the respective oils and strains. The essential oil from Anethum graveolens showed antimicrobial activity against Staphylococcus aureus (inhibitory zone=18 mm), Salmonella sp. (=11 mm) and E. coli (10 mm). The Cuminum cyminum essential oil was effective against E. coli, P. aeruginosa and Salmonella sp. and their inhibitory zones were 18, 10 and 23 mm, respectively. Coriandrum sativum oil was active only against Salmonella sp. (18 mm) and Foeniculum vulgare inhibited only E. coli (9 mm).

Qualidade dos medicamentos contendo dipirona encontrados nas residências de Araraquara e sua relação com a atenção farmacêutica

Many studies had described the morbi-mortality related to medicines. As for the strategies to reduce the possible risks for medicine therapy is very important to readvise the pharmaceutical activity, once the pharmacist has potential for constitute an essential part for the solution of problems related to the utilization of medicines. The purpose of this work was to demonstrate that the therapeutic subdosage and the microbiological contamination may be directly involved with the inappropriate manipulation of medicines stored in residences. Liquid dosage forms containing dipyrone market in Brazil and stored at homes in Araraquara (SP) were analyzed regarding quantitative and microbiological analysis. Only in 57% from 128 samples analyzed the drug quantity was in accordance. Moreover, 26.2% from 128 samples analyzed presented S. aureus, E. coli and Salmonella sp. These results demonstrated clear reduction in their quality, as well as the presence of molds and/or bacteria in some medicines that still agreed with the expirations dates, showing the importance of the pharmacist in advising the correct use and store of medicines.

Antibacterial activity of gels with pomegranate, apricot and green tea glycolic extracts

Pomegranate (PGE) and green tea (GTGE) glycolic extracts are being employed in formulations because of their antiseptic and astringent effects. Apricot (AGE) glycolic extract possesses function cooling and antibacterial. The aim was to verify the antibacterial activity of these extracts incorporated in gel base. The antibacterial activity was verified by diffusion in agar method, using cylinder in plate. Plates containing Staphylococcus aureus (ATCC 6538p), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 10536) and Salmonella sp. (ATCC 19196) were incubated at 37°C for 24 hours. After incubation, the results were analysed with a pachymeter, observing the bacterial growth inhibition halo diameter and the statistical significance level was determined. PGE presented activity only against P. aeruginosa; GTGE presented activity against S. aureus, P. aeruginosa and E. coli; and AGE presented activity against P. aeruginosa and Salmonella sp. According to the experimental conditions, it is possible to conclude that GTGE presented the greater growth inhibition halo diameter when compared with other extracts, suggesting higher antibacterial action of this extract.
