The use of Fourier Transform-Infrared Spectroscopy (FT-IR) in conjunction with Artificial Neural Network software NeuroDeveloper™ was examined for the rapid identification and classification of Listeria species and serotyping of Listeria monocytogenes. A spectral library was created for 245 strains of Listeria spp. to give a biochemical fingerprint from which identification of unknown samples w...

Capparis spinosa ethanolic extract: phenol, flavonoid, antioxidant potential and antibacterial activity on Enterobacter aerogenesis, Escherichia coli, Staphylococcus aureus Listeria monocytogenes

There is general agreement that listeriosis has a significant impact on Man as well as on animals. Listeria monocytogenes has been isolated from the faeces of healthy human and animal carriers and from various environmental sources. L. monocytogenes is the pathogenic species most responsible for abortion, septicaemia and meningitis in animals and Man. Listeria ivanovii is a primary cause of abo...

Listeria sps are ubiquitous in nature. Infection due to L. monocytogenes causes illness in animals and humans worldwide. Aim of the present study was to standardize a multiplex PCR for the identification and differentiation of important Listeria species, in particular, Listeria monocytogenes and to detect toxigenic potential of L. monocytogenes. Employing primers for truncated regions of seven ...

Listeria (L.) monocytogenes is an ‘emerging food borne pathogen’ that poses threat to global food safety. Its occurrence in milk and milk products constitute a negative impact to the dairy industry. Despite its veterinary public health significance, only few studies are available on the prevalence and characteristics of the organism from milk and milk products in Nigeria. The main objectives of...

AIMS This study investigated the performance of a new chromogenic plating medium for the detection of Listeria monocytogenes from naturally contaminated samples obtained from marine environments in Morocco in comparison with the conventional plating media PALCAM and Oxford. METHODS A total of 479 marine samples (sea water, sediment and mussels) were collected from 16 littoral sites in the reg...

Listeriosis outbreaks are frequently multistate/multicountry outbreaks, underlining the importance of molecular typing data for several diverse and well-characterized isolates. Large-scale whole-genome sequencing studies on Listeria monocytogenes isolates from non-U.S. locations have been limited. Herein, we describe the draft genome sequences of 510 L. monocytogenes isolates from northern Ital...
