25. HEALTH PROFILE OF BOVINE CURRALEIRO FRONT OF RACE The disease of economic importance / PERFIL SANITÁRIO DE BOVINOS DA RAÇA CURRALEIRO FRENTE A ENFERMIDADES DE IMPORTÂNCIA ECONÔMICA
Com o objetivo de ampliar os conhecimentos sobre os aspectos sanitários de bovinos da raça Curraleiro, foi realizado o estudo comparativo entre animais Curraleiros e outras raças bovinas (Guzerá, Nelore, Girolando e Caracu), em relação a enfermidades de importância econômica e epidemiológica para pecuária. Para tanto avaliou-se a ocorrência de eve

26. Isolamento e atividade antimicrobiana de actinomicetos endofÃticos e da rizosfera de melÃo-de-sÃo caetano (Momordica charantia L.)
As plantas medicinais constituem uma fonte valiosa para o isolamento de microrganismos capazes de produzir diversas molÃculas bioativas. Momordica charantia L., conhecida popularmente como MelÃo-de-SÃo Caetano, pertence à famÃlia das CucurbitÃceas e à uma planta muito utilizada na medicina popular para o tratamento de vÃrias afecÃÃes de origem micr

27. Isolamento de Mycobacterium spp. do leite de vacas suspeitas e positivas para tuberculose
Considerando-se o risco à saúde pública representado pela eliminação de micobactérias pelo leite, foram colhidas 780 amostras de 52 fêmeas bovinas leiteiras consideradas suspeitas ou positivas para tuberculose ao teste de Stormont. As amostras foram submetidas à pesquisa de Mycobacterium spp. e consistiam de 300 ml de leite/vaca, colhidos na primeira

28. Use of a siderophore detection medium, ethylene glycol degradation, and beta-galactosidase activity in the early presumptive differentiation of Nocardia, Rhodococcus, Streptomyces, and rapidly growing Mycobacterium species.
A simplified scheme for the presumptive early identification of Nocardia, Rhodococcus, rapidly growing Mycobacterium, and Streptomyces species is presented. The Nocardia and Streptomyces spp. and the Mycobacterium spp. were positive. The spp. were positive for siderophore activity, but only 25% of the Rhodococcus spp. were positive. The Rhodococcus and Mycob

29. Aerobic Degradation of 1,1,1-Trichloroethane by Mycobacterium spp. Isolated from Soil
Two strains of 1,1,1-trichloroethane (TCA)-degrading bacteria, TA5 and TA27, were isolated from soil and identified as Mycobacterium spp. Strains TA5 and TA27 could degrade 25 and 75 mg · liter of TCA−1 cometabolically in the presence of ethane as a carbon source, respectively. The compound 2,2,2-trichloroethanol was produced as a metabolite of the degrad

30. GenoType Mycobacterium Assay for Identification of Mycobacterial Species Isolated from Human Clinical Samples by Using Liquid Medium
The GenoType Mycobacterium assay was used to identify 98 mycobacteria isolates by using liquid cultures from positive BACTEC, MGIT, and ESP bottles. This system identifies 16 mycobacteria. There was complete agreement between the GenoType results and the laboratory identifications for Mycobacterium tuberculosis complex and other Mycobacterium spp. GenoType a

31. Identification of Mycobacterium spp. by Using a Commercial 16S Ribosomal DNA Sequencing Kit and Additional Sequencing Libraries
Current methods for identification of Mycobacterium spp. rely upon time-consuming phenotypic tests, mycolic acid analysis, and narrow-spectrum nucleic acid probes. Newer approaches include PCR and sequencing technologies. We evaluated the MicroSeq 500 16S ribosomal DNA (rDNA) bacterial sequencing kit (Applied Biosystems, Foster City, Calif.) for its ability

33. Activities of the glycylcyclines N,N-dimethylglycylamido-minocycline and N,N-dimethylglycylamido-6-demethyl-6-deoxytetracycline against Nocardia spp. and tetracycline-resistant isolates of rapidly growing mycobacteria.
Susceptibilities to the new semisynthetic tetracycline (Tet) compounds N,N-dimethylglycylamido-minocycline (DMG-MINO) and N,N-dimethylglycylamido-6-demethyl-6-deoxytetracycline (DMG-DMDOT) were compared with those to doxycycline, minocycline, and Tet for 198 Tet-resistant (Tetr) and 33 Tet-susceptible (Tets) clinical isolates of rapidly growing mycobacteria

34. Influence of Environmental Gradients on the Abundance and Distribution of Mycobacterium spp. in a Coastal Lagoon Estuary▿
Environmental mycobacteria are of increasing concern in terms of the diseases they cause in both humans and animals. Although they are considered to be ubiquitous in aquatic environments, few studies have examined their ecology, and no ecological studies of coastal marine systems have been conducted. This study uses indirect gradient analysis to illustrate t

35. Quantitative Analysis of Mycobacterial and Propionibacterial DNA in Lymph Nodes of Japanese and European Patients with Sarcoidosis
The cause(s) of sarcoidosis is unknown. Mycobacterium spp. are suspected in Europe and Propionibacterium spp. are suspected in Japan. The present international collaboration evaluated the possible etiological links between sarcoidosis and the suspected bacterial species. Formalin-fixed and paraffin-embedded sections of biopsy samples of lymph nodes, one from

36. Specific inhibition of spermidine synthesis in Mycobacteria spp. by the dextro isomer of ethambutol.
Only the dextro isomer of ethambutol inhibited mycobacterial spermidine synthase and spermidine biosynthesis. Inhibition of mycobacterial spermidine synthase appeared to be specific. Spermidine synthase from Mycobacterium fortuitum, which was resistant to ethambutol in vitro, required a higher concentration of ethambutol for its inhibition than the enzyme of
