A previously healthy 74-year-old Caucasian man with penicillin allergy was admitted with evolving headache, confusion, fever, and neck stiffness. Treatment for bacterial meningitis with dexamethasone and monotherapy ceftriaxone was started. The cerebrospinal fluid showed negative microscopy for bacteria, no bacterial growth, and negative polymerase chain reaction for bacterial DNA. The patient ...

Using phenotype techniques, characterization was realized of species and serovars of 255 strains of Listeria isolated from human material: 220-86.3% were from patients with possible invasive disease, while 35-13.7% were from colonized healthy individuals. The strains were collected in several regions of Brazil from 1969-2000. In individuals aged 0-10 or 41-60 years old Listeria monocytogenes wa...

INTRODUCTION Listeria monocytogenes is considered one of the most important food-borne pathogens transmitted to humans via contaminated food. The aim of the present study was to demonstrate the importance of L. monocytogenes as a food-borne pathogen. METHODOLOGY A total of 340 samples were collected from different localities in El Giza Governorate, Egypt, to check the occurrence of L. monocyt...

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...
