ABSTRACT. Pyogenic hepatic abscess (PHA) is a rare but potentially serious disease. Investigations of new therapeutic methods urgently need experimental support in corresponding animal models. However, to date, few studies have evaluated PHA in the minipig. The linear regression equation of the Staphylococcus aureus ATCC 25923 strain was established. PHA was successfully mocked, and S. aureus ATCC 29213 was the only pathogenic bacterium identified. The abscess formation stage was observed on the 21st day of the operation. This study will provide a baseline for further studies evaluating new treatment methods for PHA.
Porphyromonas gingivalis W50 adheres in vitro to biofilms of Streptococcus gordonii G9B. This phenomenon is believed to facilitate the initial colonization of the oral cavity by P. gingivalis and to contribute to the maturation of dental plaque. In this report, we describe the modulating effects of human submandibularsublingual saliva (HSMSL) on this in vitro model of intergeneric bacterial adhesion (coaggregation). HSMSL inhibited P. gingivalis adhesion to S. gordonii by 50% at a concentration of 57 t.g of protein per ml.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
