Ecology of Listeria monocytogenes and Listeria species in India: the occurrence, resistance to biocides, genomic landscape and biocontrol

Abstract

Summary Listeria monocytogenes, the causative agent of listeriosis, has been implicated in increasing foodborne outbreaks worldwide. The disease is manifested in various forms ranging from severe sepsis in immune‐compromised individuals, febrile gastroenteritis, still birth, abortions and meningoencephalitis. In India, data from studies on the detection and molecular epidemiological analysis of L. monocytogenes are only recently emerging. The presence of Listeria in different ecological niches has been recorded from India, including foods, soil, vegetables, mangrove swamps, seafood, freshwater fishes, clinical cases, and also insects. The organism has also been isolated from women with spontaneous abortions, miscarriage or recurrent obstetric history, aborted foetuses, animal clinical cases and wildlife samples. A novel species of Listeria has also been characterized. Listeria monocytogenes strains isolated from clinical, environmental, and foods showed biofilm‐forming abilities. Listeria monocytogenes serotype 4b isolates of ST328, a predominant and unique ST observed in India, was repeatedly isolated from different sources, times, and geographical locations. Here, we reviewed the occurrence of Listeria in different sources in India, its resistance to biocides, and provide epidemiological analysis on its genomic landscape.

Genomic epidemiology of the clinically dominant clonal complex 1 in the Listeria monocytogenes population in the UK

“…Listeriosis is a systemic infection caused by the Gram-positive bacterium Listeria monocytogenes . The genus Listeria comprises at least 26 species [1–4], and is ubiquitous in plant, water and soil environments [5]. L.…”

“…Listeriosis is a systemic infection caused by the Gram-positive bacterium Listeria monocytogenes. The genus Listeria comprises at least 26 species [1][2][3][4], and is ubiquitous in plant, water and soil environments [5]. L. monocytogenes and Listeria ivanovii are the two species within this genus known to cause infection in humans and animals, with L. monocytogenes being the leading cause of human clinical listeriosis [6].…”

Effect of different process conditions on the physicochemical and antimicrobial properties of plasma-activated water

“…monocytogenes (G + ) is also a highly lethal zoonotic pathogen that can cause sepsis and meningitis, with strong survivability, and can survive in soil, feces, and hay. L. monocytogenes as a 'refrigerator killer' can grow at refrigerator conditions and is one of the main pathogenic bacteria in refrigerated food [11]. Some of the traditional sterilization methods have risks to the environment and human health due to reagent residues [12].…”

The assessment of microbial ecology: a special emphasis on the Indian scenario

“…Multiple ST328 isolates of Listeria monocytogenes serotype 4b were identified from different sources, times and geographical locations throughout India. In the review published in this issue, the authors examined the occurrence of Listeria in different sources in India, its genomic landscape and its resistance to biocides (Barbuddhe et al ., 2021). Another article in this issue focuses on the symbiosis of NF‐containing species with legumes, i.e.…”
