parvula, very small . Gender: feminine . Type strain: ATCC 10790; CCUG 5123; DSM 2008; JCM 12972; NCTC 11810 Veillonella parvula is an anaerobic gram-negative coccus that is part of the normal human flora. It has rarely been identified as a pathogen in humans, and the most frequently reported infection caused by V. parvula is osteomyelitis. We report a case of bacteremia unrelated to a central venous catheter and without an underlying source of infection. 2019-08-18 · Veillonella occurs naturally in the oral mucosa of the mouth. On a microscopic level, Veillonella is seen as a round bacterium that appears in pairs, masses, or short chains.

Thegenus Veillonella. I. General cultural, ecological, and biochemical considera-tions. J. Bacteriol. 87:162-170. 1964.-Arguments are presented for excluding Veillonella discoides, V.reniformis, V. orbiculus, and V.vulvovaginitidis fromthe genus, andfor restricting it to aerogenic organisms such as V. parvula and V. alcalescens. Thegenus We herein present a case of epidural abscess caused by V. parvula in a 68-year-old man with sinus squamous cell carcinoma who presented with a 3-week history of low back pain.Blood and pus cultures were positive for Veillonella spp.

Veillonella alcalescens Översikt Finlands Artdatacenter - Laji.fi

Propionibacteria and several other genera of anaerobic bacteria such as Veillonella, Selenomonas, and Clostridium, especially Clostridium propionicum, produce propionic acid as a main fermentation product. Propionibacteria are Gram-positive, non-spore-forming, nonmotile, anaerobic, and rod-shaped bacteria. The succinate pathway is widespread among Bacteroides spp., and is also found in several organisms belonging to the Negativicutes class of the phylum Firmicutes, such as Veillonella parvula [58]. In the Bacteroides version of the propionate fermentation pathway, ATP is generated using a primitive form of anaerobic respiration, where fumarate acts as a terminal electron acceptor and is converted to succinate [24] . Conclusions: Our findings indicate that V. parvula is not, as previously thought, protective and associated with caries health. On the contrary, V. parvula might participate in caries development through interactions with S. mutans. This study suggests that V. parvula may have an impact on the pathogenesis of dental caries.
