Detection and serotyping of Listeria monocytogenes in some food products from North-East of Romania

Abstract

Listeria monocytogenes represents an important hazard to human health because it is capable of causing listeriosis, an atypical foodborne disease with a high fatality rate.The aim of this study was to detect and serotype Listeria monocytogenes in some food products (of animal and vegetable origin)

Prevalence of Pathogens in Poultry Meat: A Meta-Analysis of European Published Surveys

“…After assessing all the information from the recovered publications, seventy-eight primary studies [6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,…”

Antibiotic Susceptibility Profiles of Listeria monocytogenes Strains Isolated from Food Products and Clinical Samples

“…The limited number of clinical strains can be explained by the fact that listeriosis is less common in Romania compared to other European countries, while food isolates of L. monocytogenes are usually unreported, thus making it difficult to gather a large collection of strains. Also, a recent study had shown that out of twenty five samples positive for L. monocytogenes by classical microbiological method, only 22 were confirmed by real-time PCR, suggesting that using only the standard method can lead to false results (14).…”

Scientific Achievements in the Study of the Occurrence and Antimicrobial Susceptibility Profile of Major Foodborne Pathogenic Bacteria in Foods and Food Processing Environments in Romania: Review of the Last Decade

“…Cărare et al, [15] E. coli [13]. The readyto-eat (RTE) products are considered high-risk foods, because they support the growth of L. monocytogenes and do not require heat treatment before consumption.…”

“…Over the last decade, in Romania, there was a total of nine studies that published data on the isolation frequency of L. monocytogenes from a food matrix or food processing environment. The pathogen was recovered from a variety of food products, including raw (pork, beef, sheep, poultry, and snail) and mechanically processed meat, RTE, milk and dairy products, chicken carcasses, fish, and fresh salads [5,6,10,[14][15][16], with different prevalence values as highlighted in Table 1. Two studies were designed to identify L. monocytogenes predominantly in the food processing environment, including food contact and nonfood contact surfaces [14,17].…”

“…Four studies, based on molecular serotyping tools, have provided data on the genetic diversity of a total of 98 L. monocytogenes strains [10,[14][15][16]. The multiplex PCR serotyping techniques have revealed the occurrence of five major subtypes namely, 1/2a (67.3%) as dominant subtype, followed by 1/2c (21.4%), 1/2b (5.1%), 4b (4.1%), and 4a (2.0%), respectively.…”
