In vitro susceptibility testing of phytochemicals from essential oils against Prototheca species
Phytochemicals isolated from essential oils are effective alternatives for inhibiting microbial pathogens. Bovine protothecal mastitis is the cause of a reduction in milk production and the secretion of thin, watery milk with white flakes. In the present study, we performed in vitro susceptibility t...

| description | Phytochemicals isolated from essential oils are effective alternatives for inhibiting microbial pathogens. Bovine protothecal mastitis is the cause of a reduction in milk production and the secretion of thin, watery milk with white flakes. In the present study, we performed in vitro susceptibility testing of the phytochemicals carvacrol, citral, and thymol in Prototheca strains isolated from cases of protothecosis in small animals and cow feces. The susceptibility of the algae to carvacrol, citral, and thymol was assessed using the modified CLSI M27-A3 broth microdilution method. The ranges of the minimum inhibitory concentrations (MIC%) of the phytochemicals in all isolates were 0.03% to 0.125% for carvacrol, 0.03% to 0.25% for citral, and 0.06% to 0.25% for thymol. Based on these results, carvacrol, citral, and thymol appear effective against Prototheca species at the tested concentrations, and may thus be useful for environmental disinfection in barns. |
