Modificação da microbiota associada às lesões peridentárias da cara inchada em bezerros transferidos para área indene

Observations on the epizootiology of cara inchada in cattle (CI) indicated that animals affected by the disease recover spontaneously when they are transferred from the CI-prone area to CI-free pastures. In the presente study 13 young bovines with actively progressing periodontal CI-lesions were transferred to a CI-free area, in order to investigate the clinical course of the disease and the composition of the microflora in the periodontal lesions in two distinct situations: (1) in the actively progressing lesions, and (2) in the healed periodontal pouches of clinically recovered animals. The semi-quantitative and qualitative bacteriological study was undertaken in regard to the percentage of black-pigmented Bacteroides in cultures. In the actively progressing lesions of the 13 CI-diseased bovines the percentage of these bacteria was 71.3% in average. The evaluation of the composition of the microflora in the healed periodontal pouches of the clinically recovered bovines showed that bacteria of the black-pigmented Bacteroides group existed only at an average of 1.7%. The results of this investigation give further support for the infectious nature of the CI-periodontitis and the primary involvement of these bacteria.

Colheita de líquido cefalorraquidiano em cães: modificação de técnica prévia

Unlike the already described techniques, which are based on imaginary lines among extremities or bone projections, this research describes a collection technique modification of cerebrospinal fluid (CSF) in dogs, in the atlantooccipital space. The palpation of bone structures in this joint, plus the supported directioning of the needle, does make the collection easy, even by professionals which have no experience in this kind of procedure. The applied technique enabled the collection of adequate volumes of limpid and colorless CSF of 50 healthy dogs in the first attempt of collection. There was no contamination with blood during the procedure, what made possible the correct interpretation of laboratory parameters usually examined in CSF samples.

Effects of different disinfection treatments on the natural microbiota of lettuce

In this study, water and eight sanitizing solutions (vinegar at 6, 25, and 50%; acetic acid at 2 and 4%; peracetic acid at 80 ppm, sodium hypochlorite at 200 ppm, and sodium dichloroisocyanurate at 200 ppm) were compared in terms of their effectiveness against the natural microbiota of lettuce. All of the samples were kept in contact with the sanitizing solutions for 15 min, and the effectiveness of a sanitizing agent was evaluated on the basis of the number of decimal reductions of the total aerobic mesophilic count, the mold and yeast count, the total coliform count, and the Escherichia coli count. The average initial levels of these organisms in the samples were 6.94 log(10) CFU/g for aerobic mesophilic microorganisms, 5.62 log(10) CFU/g for molds and yeasts, and 3.25 log(10) CFU/g for total coliforms. of 10 samples analyzed, only 4 contained E. coli, and the average initial level of this microorganism in these 4 samples was 1.64 log(10) CFU/g. Salmonella was not detected in any of the samples tested. The decimal reductions of the populations of aerobic mesophilic microorganisms, molds and yeasts, total coliforms, and E. coli were 0.78, 0.87, 0.82, and >0.14 log(10) CFU/g, respectively, in water; 2.89, >3.41, >2.21, and >0.26 log(10) CFU/g, respectively, in 50% vinegar; 2.42, >3.20, >1.99, and >0.26 log(10) CFU/g, respectively, in 25% vinegar; 1.83, 2.57, 1.58, and >0.26 log(10) CFU/g, respectively, in 6% vinegar; 3.91, >3.58, >2.25, and >0.26 log(10) CFU/g, respectively, in 4% acetic acid; 3.37, >3.53, >2.25, and >0.26 log(10) CFU/g, respectively, in 2% acetic acid; 1.85, 2,32, 1.44, and >0.20 log(10) CFU/g, respectively, in 80 ppm of peracetic acid; 2.63, 2.75, 1.91, and >0.26 log(10) CFU/g, respectively, in 200 ppm of sodium hypochlorite; and 3.23, >3.08, >1.95, and >0.26 log(10) CFU/g, respectively, in 200 ppm of sodium dichloroisocyanurate. Statistical analysis of the results showed that the effectiveness levels for all of the sanitizing agents tested were equivalent to or higher than that for sodium hypochlorite at 200 ppm.

Microbiota intestinal de indivíduos que sofreram acidente ocupacional com materiais biológicos e que realizaram profilaxia anti-retroviral

Avaliar a microbiota intestinal de indivíduos que sofreram acidente ocupacional com materiais biológicos e receberam anti-retrovirais foi o objetivo deste estudo. O grupo de estudo constou de 23 indivíduos com idade entre 18-45 anos, sendo 13 doadores de sangue e 10 que sofreram acidente ocupacional. Foram avaliados a microbiota intestinal, antropometria e exames laboratoriais pré, pós e 30 dias após o término da medicação. Zidovudina mais lamivudina foi utilizada em 70% dos indivíduos associado ao nelfinavir, 20% ao efavirenz e 10% ao ritonavir. As alterações nutricionais e dietéticas-laboratoriais e de microbiota intestinal foram analisadas em três momentos. M1: até dois dias do início da profilaxia; M2: no último dia da profilaxia e M3: 30 dias após o término da profilaxia. Náuseas, vômitos e diarréia estiveram presentes em 50% no segundo momento do estudo. Sobrepeso em 70%, desnutrição e eutrofia em 10%, dos indivíduos, não se modificaram durante o estudo. Transaminases, triglicérides, LDL-colesterol se elevaram no segundo momento e normalizaram 30 dias após término da medicação. Houve redução significativa dos Lactobacillus, Bifidobacterium e Bacteróides nos três momentos. Uso de anti-retrovirais provocou impacto significativo na microbiota intestinal dos indivíduos, sem recuperação em 30 dias.
