Aislamiento y caracterización de Streptococcus bovis y estudio inicial para el aislamiento de su bacteriófago
Provedor de dados: 32
Autores: López Garrido, Serafín Jacobo.
El objetivo del presente estudio fue obtener un cultivo puro de la bacteria ruminal  Streptococcus bovis a partir de líquido ruminal de ovinos alimentados con una dieta  alta en sorgo (70 % en base seca). Además, se analizó su actividad fermentativa  (producción de AGV y lactato) y el proceso de liofilizado como método de  conservación, y se realizaron ensayos para expresar su bacteriófago. Para el  aislamiento se usó un medio comercial para Streptococcus spp. (Merck) preparado  bajo anaerobiosis. Para la identificación se usó el sistema API 20 Strep, reacción  catalasa, morfología celular y tinción de Gram. Con la prueba API 20 Strep se  comprobó que la bacteria aislada pertenece a la especie S. bovis. Esta bacteria  tiene forma esférica a ovoide, de 0.8...

The objective of this work was to isolate and characterize tannin-tolerant ruminal bacteria from crossbred Holstein x Zebu cows fed a chopped mixture of elephant grass (Pennisetum purpureum), young stems of "angico-vermelho" (Parapiptadenia rigida), and banana tree (Musa sp.) leaves. A total of 117 bacteria strains were isolated from enrichment cultures of rumen microflora in medium containing tannin extracts. Of these, 11 isolates were able to tolerate up to 3 g L-1 of tannins. Classical characterization procedures indicated that different morphological and physiological groups were represented. Restriction fragments profiles using Alu1 and Taq1 of 1,450 bp PCR products from the 16S rRNA gene grouped the 11 isolates into types I to VI. Sequencing of 16S...

Spontaneous bacterial peritonitis caused by Streptococcus bovis: case report and review of the literature

Spontaneous bacterial peritonitis (SBP) is a frequent and severe complication that occurs in patient with cirrhosis and ascites. It occurs in 10% to 30% of patients admitted to hospital. The organisms that cause SBP are predominantly enteric. Escherichia coli is the most frequent recovered pathogen, and Gram-positive bacteria, mainly Staphylococcus spp., are being considered an emerging causative agent of SBP. Streptococcus bovis that may be found as part of the commensal bowel flora in about 10% of healthy adults constitute an uncommon cause of peritonitis that was first reported in 1994. We describe the first case of SBP at the University Hospital of Santa Maria (HUSM) caused by S. bovis, resistant to the antibiotics erythromycin and clindamycin...
