| identification of equine cecal bacteria producing amines in an in vitro model of carbohydrate overload. | acute laminitis has been associated with the overgrowth of gram-positive bacteria within the equine hindgut, causing the release of factor(s) leading to ischemia-reperfusion of the digits. the products of fermentation which trigger acute laminitis are, as yet, unknown; however, vasoactive amines are possible candidates. the objectives of this study were to use an in vitro model of carbohydrate overload to study the change in populations of cecal streptococci and lactobacilli and to establish whe ... | 2003 | 12676687 |
| no synthesis in human saliva. | human saliva contains nitrate that is converted into nitrite by the activity of facultative, anaerobic bacteria of the oral cavity. nitrite can be reduced to no in the acidic gastric milieu; some no may also form in the mouth at acidic ph values. in this paper, we show that bacteria (s. salivarius, s. mitis and s. bovis) isolated from saliva, may contribute to no production in human saliva. no formation by bacteria occurs at neutral ph values and may contribute to the antibacterial activity of s ... | 2003 | 12653214 |
| [streptococcus bovis endocarditis - predictor of colonic carcinoma? ]. | the association of streptococcus bovis endocarditis with colonic neoplasia is classically described and exceeds 50 percent. the prevalence of streptococcus bovis in fecal cultures from patients with carcinoma of the colon is significantly increased (56%) as compared to that in controls (10%) and also in patients with inflammatory bowel disease (28%). streptococcus bovis endocarditis is relatively benign, but it stresses the frequency of the associated colonic carcinoma, requiring colonoscopy and ... | 2003 | 12626871 |
| molecular characterization of hpr and related enzymes, and regulation of hpr phosphorylation in the ruminal bacterium streptococcus bovis. | molecular properties of hpr, enzyme i, and hpr kinase in streptococcus bovis, and the regulation of hpr phosphorylation were examined. the genes encoding hpr (ptsh) and enzyme i (ptsi) were found to be cotranscribed. two transcriptional start sites were detected in a region upstream of the hpr kinase gene (hprk). hpr kinase had both hpr-phosphorylating and hpr-dephosphorylating activities. the importance of phosphorylation of ser-46 in hpr was shown by using a mutant hpr in which ser-46 was repl ... | 2003 | 12610726 |
| diet influences the ecology of lactic acid bacteria and escherichia coli along the digestive tract of cattle: neural networks and 16s rdna. | in this manuscript, the authors have sought to gain a better understanding of the interactions between escherichia coli and lactic acid bacteria (lab) isolated from rogossa mrs agar along the digestive tract of grain- and forage-fed cattle. e. coli from cattle receiving a high-grain diet were more numerous (p<0.05) than from the high-forage diet and the highest numbers were in the faeces. isolates on rogossa mrs agar were always greater in the high-grain diet (p<0.05) and contained a significant ... | 2003 | 12576580 |
| molecular diagnosis of infective endocarditis by pcr amplification and direct sequencing of dna from valve tissue. | we used broad-range eubacterial pcr amplification followed by direct sequencing to identify microbial pathogens in heart valve material from 29 patients with histologically confirmed infective endocarditis and 23 patients free of infective endocarditis. microorganisms cultured by conventional techniques matched those identified by pcr in 21 cases. pcr alone identified the causative agent in three cases (streptococcus bovis, staphylococcus cohnii, and coxiella burnetii), allowing better patient m ... | 2003 | 12574279 |
| regulation of lactate dehydrogenase synthesis in a ruminal bacterium, streptococcus bovis. | lactate dehydrogenase (ldh) was purified from three strains of streptococcus bovis, and the gene ldh was cloned and sequenced. the ldh of s. bovis from a goat (th1) was different from the ldhs of two other strains from cattle (th2, jb1) in that asp(220) was substituted for glu. northern blot analysis revealed that the ldh-mrna of s. bovis was approximately 1.0 kbp, which was transcribed in a monocistronic fashion. when cells were grown at ph 6.9 in a batch culture, the level of ldh transcript de ... | 1997 | 12501303 |
| lotus corniculatus condensed tannins decrease in vivo populations of proteolytic bacteria and affect nitrogen metabolism in the rumen of sheep. | condensed tannins in forage legumes improve the nutrition of sheep by reducing ruminal degradation of plant protein and increasing crude protein flow to the intestine. however, the effects of condensed tannins in forage legumes on rumen bacterial populations in vivo are poorly understood. the aim of this study was to investigate the specific effects of condensed tannins from lotus corniculatus on four proteolytic rumen bacteria in sheep during and after transition from a ryegrass (lolium perenne ... | 2002 | 12489781 |

| spontaneous bacterial peritonitis caused by streptococcus bovis: case series and review of the literature. | streptococcus bovis is the rare cause of spontaneous bacterial peritonitis in decompensated cirrhosis. s. bovis bacteremia has long been known to be associated with colon cancer. we describe seven patients and review the seven previous reports of spontaneous bacterial peritonitis patients with s. bovis infection. most of the patients had cirrhosis and presented with fever, abdominal pain, abdominal distention, and jaundice. colonic adenomatous polyps with dysplastic change were found in 18.2% of ... | 2002 | 12094869 |
| special issues in the management of infective endocarditis caused by gram-positive cocci. | gram-positive cocci, mainly streptococci and staphylococci, continue to cause the majority of cases of infective endocarditis. among the streptococci causing ie, the long-standing predominance of oral or viridans-group streptococci has progressively faded, while the number of cases caused by "enteric streptococci" (streptococcus bovis and enterococci) has increased. while most oral streptococci and s. bovis strains remain fully sensitive to penicillin, nutritionally variant streptococci--now ren ... | 2002 | 12092481 |
| source of enterococci in a farmhouse raw-milk cheese. | enterococci are widely distributed in raw-milk cheeses and are generally thought to positively affect flavor development. their natural habitats are the human and animal intestinal tracts, but they are also found in soil, on plants, and in the intestines of insects and birds. the source of enterococci in raw-milk cheese is unknown. in the present study, an epidemiological approach with pulsed-field gel electrophoresis (pfge) was used to type 646 enterococcus strains which were isolated from a ch ... | 2002 | 12089042 |
| molecular characterization and expression of pyruvate formate-lyase-activating enzyme in a ruminal bacterium, streptococcus bovis. | to clarify the significance of the activation of pyruvate formate-lyase (pfl) by pfl-activating enzyme (pfl-ae) in streptococcus bovis, the molecular properties and gene expression of pfl-ae were investigated. s. bovis pfl-ae was deduced to consist of 261 amino acids with a molecular mass of 29.9 kda and appeared to be a monomer protein. similar to escherichia coli pfl-ae, s. bovis pfl-ae required fe(2+) for activity. the gene encoding pfl-ae (act) was found to be polycistronic, and the pfl gene ... | 2002 | 12089014 |
