SYNOPSIS. Inhibitors, acid production, and substrate utilization by 4 strains of Tritrichmonas foetus (BP-3, BP-4, A-1, and A-2) were studied manometrically. All used glucose, galactose, mannose, fructose, sucrose, maltose, trehalose, glycogen, starch, lactate, and pyruvate. Strain A-1, with the highest aerobic and anaerobic endogenous rates, used these substrates less than did the others. Strain BP-3 did not use lactose; strains BP-4 and A-2 did not use raffinose aerobically and only slightly anaerobically; strain A-1 used both nearly as well as maltose and sucrose. All were strongly inhibited by iodoacetate and, if tested in the presence of glucose, aerobically or anaerobically, by fluoride, arsenite, hydroxylamine, and 8-hydroxyquinoline. Aerobically, 2,4-dinitrophenol produced stimulation which was greater in the presence of glucose; anaerobically, it produced inhibition which was, in some cases, comparable to the effects produced by the other inhibitors. Fluoride, arsenite, azide, and hydroxylamine, although producing insignificant inhibitory effects on endogenous O2 consumption, reduced and, in some cases, abolished motility of all strains. All 4 strains produced acid under anaerobic and aerobic conditions; strain A-1 produced more than the others. Lactic acid accounted for 30–51% of the acid produced in all strains.Strain A-1 more closely resembled the nasal trichomonad of swine (strain PN-610) than did strain BP-1. (Doran(3)). The writer believes that the swine nasal strain is a highly adapted strain of T. foetus.
