Antibacterial activities of almond skins on cagA-positive and-negative clinical isolates of Helicobacter pylori.

Background: Helicobacter pylori is known to be a gastric pathogen of humans. Eradication regimens for H. pylori infection have some side effects, compliance problems, relapses, and antibiotic resistance.

High prevalence of arcobacter carriage in older subjects with type 2 diabetes.

Arcobacters are potential pathogens related to diarrheic infections and, rarely, septicaemia. This study evaluated the prevalence of arcobacters in stool samples of subjects with (n = 38) and without (n = 61) type 2 diabetes by using cultural and molecular techniques. Three Arcobacter positive cultures were found, all among diabetic subjects, whereas molecular analysis showed a carriage rate of 79% and 26.

New triazoles and echinocandins: mode of action, in vitro activity and mechanisms of resistance.

Different types of mycoses, especially invasive mycoses caused by yeasts and molds, are a growing problem in healthcare. The most notable explanation for this increase is a rise in the number of immunocompromised patients owing to advances in transplantation, the emergence of AIDS and a rise in the number of invasive surgical procedures. Despite advances in medical practice, some therapeutic problems remain.

Water quality and ecological status of the Alcantara River estuary (Italy).

The Alcantara River estuary was studied to obtain the first data on both water quality and ecological status of the only River Park in Sicily (Italy). Water samples were seasonally collected from three selected stations in the estuarine area and from one station at the mouth of the estuary in the marine coastal zone. Picoplankton and picophytoplankton counts were among the highest observed in estuarine environments and in other coastal waters of the Mediterranean Sea.

Detection and differentiation of Vibrio vulnificus in seawater and plankton of a coastal zone of the Mediterranean Sea.

Vibrio vulnificus, a human and animal pathogen, is present in low numbers in the Mediterranean Sea. Seawater and plankton samples were collected from a marine coastal zone of the Straits of Messina in the Mediterranean Sea (Italy) in order to investigate V. vulnificus as free-living (>0.

Detection and enumeration of Arcobacter spp. in the coastal environment of the Straits of Messina (Italy).

Seawater and plankton samples from the Straits of Messina, Italy, were analysed to confirm the occurrence of potentially pathogenic Arcobacter butzleri, A. cryaerophilus and A. skirrowii.
