Therapy of Native Valve Endocarditis Caused by Highly Penicillin-Susceptible Viridans Group Streptococci and Streptococcus bovis... 

In patients with endocarditis of prosthetic valves or other prosthetic material caused by viridans streptococci and Streptococcus bovis, treatment courses are extended to 6 weeks (Table 37-5). 

Lactic acid has a number of applications in the food industry as well as nonfood uses. The bacterium Pediococcus pentosaceus has the ability to hydrolyze inulin via an exo-inulinase and convert it to lactic acid (Middlehoven et al., 1993). Likewise, a number of Lactobacillus sp. strains and Streptococcus bovis can form lactic acid from inulin (Shamtsyan et al., 2002).

A method is given that involves fermenting Jerusalem artichoke tuber with Streptococcus bovis. This simplifies and decreases the cost of preparing L(+)-lactic acid.

TABLE 1 09—5. Therapy for Native-Valve Endocarditis Due to Strains of Viridans Streptococci and Streptococcus bovis Relatively Resistant to Penicillin G (Minimum Inhibitory Concentration > 0.1 mcg/mL and < 0.5 mcg/mL) ... 

All enterococci causing endocarditis must be tested for antimicrobial susceptibility in order to select optimal therapy (see text). This table is for endocarditis due to gentamicin- or vancomycin-susceptible enterococci, viridans streptococci with a minimum inhibitory concentration of >0.5 mcg/mL, nutritionally variant viridans streptococci, or prosthetic valve endocarditis caused by viridans streptococci or Streptococcus bovis. Antibiotic dosages are for patients with normal renal function.

Using starch as substrate yields were also low. An explanation may be that Streptococcus bovis. a homofermentative lactic acid organism common in the rumen grows rapidly on starch with low yield of biomass (jl). Table n shows some of the results for fermentation of sugar beet pulp (SBP). 

L. gallinarum, L. plantarum, Propionibacteriumfreudenreichii, and Streptococcus bovis, and these bacterial types interestingly are localized in the rumen or small intestine. As a direct-fed microbial, selected L. acidophilus strains, alone or in combination with P. freundenreichii, have been the most thoroughly studied and often are very effective at reducing the prevalence of fecal shedding of E. coli 0157 H7 when dosed at 10 cells per animal daily (Peterson et al., 2007a Tabe et al., 2008 Younts-Dahl et al., 2005).
