Mobile genetic elements of the human gastrointestinal tract

Cytomegalovirus infection of the human gastrointestinal tract.

BACKGROUND Current interest in cytomegalovirus (CMV) is largely due to an increase in the number of cases of acquired immunodeficiency syndrome and organ transplantation in recent years. The proper recognition of CMV-infected cells in gastrointestinal mucosal biopsies is critical for effective treatment of this condition. METHODS A total of 6580 endoscopic mucosal biopsies from 6323 patients ...

Assessment of microplastics in the gastrointestinal tract of some fish caught for human consumption in Bandar Abbas, the Persian Gulf

Background and Objective: Microplastics (MPs) are well-known emerging contaminants in the marine environment. A key route by which MPs can directly affect marine life is through ingestion. Materials and Methods: In order to investigate and measure MPs in the Persian Gulf, random sampling and digestion of tissues and flotation of MPs were used. This method has been used to study the frequency, ...

Bacterial biofilms in the human gastrointestinal tract.

Microbial biofilms were first described in 1936 and subsequent research has unveiled their ubiquity and physiological distinction from free-living (planktonic) microorganisms. In light of their emerging significance this review examines the bacterial biofilms within the human gastrointestinal tract. Attention is paid to the nature of these mucosally- associated populations, focusing on the prot...
