Pseudomonic acid is an antibiotic and bacterial metabolite that has been found in P. fluorescens.1 It is bacteriostatic against S. aureus (MIC = 0.05 µg/ml) and active against skin wound clinical isolates of methicillin-resistant S. aureus (MRSA; MICs = 1-4 µg/ml).2,3 Pseudomonic acid inhibits MRSA and P. aeruginosa biofilm formation in vitro.4 It inhibits bacterial cell wall isoleucyl-tRNA synthetase, slowing bacterial growth.2,4 Topical administration of pseudomonic acid (2% v/v) reduces the number of wound colony forming units (CFUs) in a mouse model of MRSA skin infection.3

Evaluation of culture media for selective enumeration of bifidobacteria and lactic acid bacteria
Braz J Microbiol 2014 Oct 9;45(3):1023-30.PMID:25477939DOI:10.1590/s1517-83822014000300035.
The purpose of this study was to test the suitability of Transgalactosylated oligosaccharides-mupirocin lithium salt (TOS-MUP) and MRS-clindamycin-ciprofloxacin (MRS-CC) agars, along with several other culture media, for selectively enumerating bifidobacteria and lactic acid bacteria (LAB) species commonly used to make fermented milks. Pure culture suspensions of a total of 13 dairy bacteria strains, belonging to eight species and five genera, were tested for growth capability under various incubation conditions. TOS-MUP agar was successfully used for the selective enumeration of both Bifidobacterium animalis subsp. lactis BB-12 and B. breve M-16 V. MRS-CC agar showed relatively good selectivity for Lactobacillus acidophilus, however, it also promoted the growth of Lb. casei strains. For this reason, MRS-CC agar can only be used as a selective medium for the enumeration of Lb. acidophilus if Lb. casei is not present in a product at levels similar to or exceeding those of Lb. acidophilus. Unlike bifidobacteria and coccus-shaped LAB, all the lactobacilli strains involved in this work were found to grow well in MRS pH 5.4 agar incubated under anaerobiosis at 37 °C for 72 h. Therefore, this method proved to be particularly suitable for the selective enumeration of Lactobacillus spp.
