Mosquito midgut plays a crucial role in its vector susceptibility and pathogen interaction. Identification of the sustainable microflora of the midgut environment can therefore help in evaluating its contribution in mosquito-pathogen interaction and in turn vector competence. To understand the bacterial diversity in the midgut of Aedes aegypti mosquitoes, we conducted a screening study of the g...

The microbiota of the human large intestine influences health and well-being. Whereas it has long been accepted that gut bacteria play a role in host pathogenesis, current opinion is that certain microflora components can have beneficial effects on gastroenteritis resistance, blood lipids, antitumor properties, lactose tolerance, and gastrointestinal immunity. It is postulated that in the infan...

BACKGROUND/AIMS We investigated gut flora characteristics in patients with functional constipation (FC) and influences of short-term treatment with VSL#3 probiotic on flora and symptom improvement. METHODS Thirty patients fulfilling Rome III criteria for FC and 30 controls were enrolled. Fecal samples were obtained before and after VSL#3 intake (one sachet twice daily for 2 weeks) and flora w...

We have developed experimental murine Campylobacter infection models which demonstrate efficient establishment and reproducible, high-level colonization. Following oral inoculation, wild-type C3H mice with normal enteric flora were colonized inconsistently and inefficiently by C. jejuni strain 81-176. However, C3H mice with a limited gut flora (LF) were efficiently colonized at high levels (10(...

Acute pancreatitis is a potentially fatal condition, and its incidence is increasing. Bacterial translocation and end organ failure are the main causes of death. Gut flora have the potential for modulation of the inflammatory cascade. Fasting has a negative impact on gut flora. Animal studies suggested a role for probiotics in the treatment of severe acute pancreatitis; however, a very recent h...

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder with an estimated worldwide prevalence of 10-20%. IBS can be associated with severe gastrointestinal symptoms, including abdominal pain, bloating, and altered bowel function. Although the causes of IBS remain undefined, recent research has increasingly suggested roles for gut flora in IBS. These roles involve postin...
