    It consists of a combination of two antibacterial agents, bacitracin (C66H101N17O16SZn) and neomycin (C23H46N6O13). Bacitracin is mainly active against gram-positive organisms, such as Clostridia, Corynebacterium Diphtheriae, Hemolytic streptococci, Staphylococci, Treponema. Bacitracin is also active on some gram-negative pathogens such as Haemophilus influenzae, Neisseria, in addition to Actinomycetes and Fusobacteria. Resistance to bacitracin is extremely uncommon. Meanwhile, neomycin acts on…

Streptococcal anaerobes inhabit the gingival crevice. ‘The pharynx can be a point of entry and initial colonization for Neisseria, Bordetella, Corynebacterium, and Streptococcus spp.’ Davis (1996). S. mutans is implicated to cause cavities and periodontitis leading to tooth loss. Periodontitis is also linked to heart disease. Ouyang et al (2000).

    and wound healing [11]. It can also be used as a precursor for the synthesis of other amino acids, such as arginine and citrulline, and putrescine, an important diamine used as a nylon precursor [28]. L-Ornithine could be produced by fermentation using auxotrophic mutants, for example, citrulline- or arginine-required mutants of Acinetobacter lwoffi and Coryneform bacterium obtained by traditional mutagenesis [1,6,18]. However, the product yield of L-ornithine is low and growth of the…
