Evaluation of Two Multiplex PCR-High-Resolution Melt Curve Analysis Methods for Differentiation of Campylobacter jejuni and Campylobacter coli Intraspecies.

Campylobacter infection is a common cause of bacterial gastroenteritis in humans and remains a significant global public health issue. The capability of two multiplex PCR (mPCR)-high-resolution melt (HRM) curve analysis methods (i.e.

Differentiation of Campylobacter jejuni and Campylobacter coli Using Multiplex-PCR and High Resolution Melt Curve Analysis.

Campylobacter spp. are important causes of bacterial gastroenteritis in humans in developed countries. Among Campylobacter spp.

The interplay between Campylobacter and Helicobacter species and other gastrointestinal microbiota of commercial broiler chickens.

Background: Poultry represent an important source of foodborne enteropathogens, in particular thermophilic Campylobacter species. Many of these organisms colonize the intestinal tract of broiler chickens as harmless commensals, and therefore, often remain undetected prior to slaughter. The exact reasons for the lack of clinical disease are unknown, but analysis of the gastrointestinal microbiota of broiler chickens may improve our understanding of the microbial interactions with the host.

A novel miniaturized most probable number method for the enumeration of Campylobacter spp. from poultry-associated matrices.

A novel miniaturized most probable number (mMPN) method was developed for the enumeration of thermophilic Campylobacter spp. using a modification of blood-free Bolton broth (supplemented with 25mg/l of sulfamethoxazole) and CampyFood ID agar. The mMPN was evaluated by comparison with direct plating (modified ISO/TS, 10272-2:2006) for the analysis of samples (n=149) representing various poultry matrices (carcases, broiler ceca and feces, scald tank water and feed).
