The paper reports on the drawing up and experimentation of a kit of media for identification in liquid media and biotyping of H. influenza and H. parainfluenza. The kit is made up of 14 components, out of which the following were prepared: basic broth, X V broth, V broth, X broth, red-phenol broth, and XV factors + ribose, xylose and saccharose, urea substrate. Moeller medium with XV, with and without ornithine, covered with paraffin oil after impregnation. In the XV broth and the broth with red phenol the XV factors and saccharose, the bands for indole and H2S were put after impregnation with bacterial culture. On these media, 175 strains of Haemophilus were identified and biotyped. 109 of them were H. influenzae and 66 H. parainfluenzae, when satellitism was used. Identification in liquid media showed that 5.5% of the H. influenza strains were H. parainfluenza and 10.6% of the H. parainfluenza strains were H. influenza. Finally, 110 strains were H. influenzae and 65 H. parainfluenzae. The components of the kit permitting identification and biotyping of H. influenzae and H. parainfluenzae are: basic broth with red phenol, X broth, XV factors supplement, V supplement, mono- and bipotassium phosphate solution, 20% urea solution, 20% saccharose, 20% ornithine, Moeller medium, bands for indole and paraffine oil.

To better understand the microbial basis of oral malodor development in humans, we used a cross-sectional and longitudinal study design and the pyrosequencing approach to track and compare the tongue microbiota associated with oral malodor in 29 Chinese adults who underwent a consecutive three-day evaluation for the amount of H2S excreted orally. Three levels of the oral malodor state (healthy, oral malodor, and severe oral malodor) were defined based on the H2S level. Community structure of the tongue plaques was more sensitive to changes of malodor state than to interpersonal variations or differences in sampling times. Within each individual, the structure of microbiota was relatively stable, while their variations were correlated with the change in the H2S level. Severe oral malodor microbiota were the most conserved in community structure, whereas the healthy ones were relatively varied. Oral-malodor-associated bacteria were identified. The relative abundance of Leptotrichia and Prevotella was positively correlated with oral malodor severity, whereas Hemophilus and Gemella exhibited a negative relationship with oral malodor severity. Our study provides one of the first landscapes of oral microbiota changes associated with oral malodor development and reveals microbes potentially useful to the evaluation and control of oral malodor.
