Phocaeicola abscessus strain 7401987(T) is the sole member of the genus Phocaeicola. This bacterium is Gram-negative, non-spore-forming, coccoid to rod-shaped and motile by lophotrichous flagella. It was isolated from a human brain abscess sample. In this work, we describe a set of features of this organism, together with the complete genome sequence and annotation. The 2,530,616 bp long genome...

1. It was demonstrated by pathogenicity and latency tests in mammals and birds that variations exist among a group of viruses, isolated from several sources and producing coccoid elementary bodies resembling those of psittacosis. 2. Active cross immunity tests emphasized these differences and confirmed their significance. 3. On the basis of the present experimental evidence the psittacosis-like...

Background: In vitro biofilm formation of H. pylori is demonstrated; however, its potential role in the persistent infection human stomach has not yet been addressed. Objectives: The aim this study was to assess clinical isolates on an epithelial cell line, a line that produces mucin. Methods: consisting efficient (19B) and weak (4B) ability, were selected from screening isolates. Their adhesio...

It was the purpose of this study to determine if a periodontal abscess could be differentiated from an endodontic abscess by the types and proportion of microorganisms found in the abscess exudate in darkfield microscopic examination. Dental abscesses with draining sinus tracts in 17 patients were studied. Eight of the abscesses were diagnosed clinically to be of endodontic origin and nine peri...

Purpose: Ureaplasma urealyticum is associated with several obstetric complications and increases the importance of risk management in pregnant women. Furthermore, U. urealyticum has been identified as a cofactor that interacts with human papillomavirus infection in cervical cancer onset. The aim of this study was to assess specific cytological features of U. urealyticum infection in Pap smears ...

We have studied initial killing, morphological alterations, the frequency of occurrence, and the selective growth of resistant subpopulations of Helicobacter pylori during exposure to amoxicillin, clarithromycin, or metronidazole by bioluminescence assay of intracellular ATP levels, microscopy, and a viable count assay. We found an induction of spheroplasts and a decrease in intracellular ATP l...
