“…The low percentage of carbapenem resistance in our study suggests that these antibiotics are still very active against multiresistant strains [55]. Antibiotic resistance among E. coli isolated from wildlife may be acquired from the food [56][57][58][59] they consume, the environment [60] and water [61]; resistance may also reflect the use of antimicrobials in humans and livestock [15,52]. Further, foodborne transmission of multiresistant E. coli has already been described as an important source of infection in mammals [15].…”

In Gabon, terrestrial mammals of protected areas have been identified as a possible source of antibiotic-resistant bacteria. Some studies on antibiotic resistance in bats have already been carried out. The main goal of our study was to detect extended-spectrum beta-lactamases (ESBLs) that are produced by enterobacteria from bats in the Makokou region in Gabon. Sixty-eight fecal samples were obtained from 68 bats caught in the forests located 1 km from the little town of Makokou. After culture and isolation, 66 Gram-negative bacterial colonies were obtained. The double-disk diffusion test confirmed the presence of ESBLs in six (20.69%) Escherichia coli isolates, four (13.79%) Klebsiella pneumoniae isolates, and one (3.45%) Enterobacter cloacae isolate. The analysis based on the nucleotide sequences of the ESBL resistance genes showed that all cefotaximase-Munichs (CTX-Ms) were CTX-M-15 and that all sulfhydryl variables (SHVs) were SHV-11: 41.67% CTX-M-15-producing E. coli, 16.67% CTX-M-15+SHV-11-producing E. coli, 8.33% CTX-M-15-producing K. pneumoniae, 25% CTX-M-15+SHV-11-producing K. pneumoniae, and 8.33% CTX-M-15-produced E. cloacae. This study shows for the first time the presence of multiresistant ESBL-producing enterobacteria in fruit bats in Makokou.

“…Food-borne pathogens are one of the main causes of foodborne diseases and they have become an important public health problem threatening people's health [1]. The Gram-positive bacterium L. monocytogenes is widely distributed in a variety of foods (meat, aquatic products, dairy products, vegetables, etc.)…”

Antimicrobial Susceptibility and Antibacterial Mechanism of Limonene against Listeria monocytogenes

2019

Limonene is a monoterpenoid compound, which is founded in a lot of plants' essential oils with good antibacterial activity against food-borne pathogens, but it has an ambiguous antimicrobial susceptibility and mechanism against Listeria monocytogenes (L. monocytogenes). In this study, the antimicrobial susceptibility of Limonene to L. monocytogenes was studied, and some new sights regarding its antibacterial mechanism were further explored. Scanning electron MICroscopy (SEM) verified that limonene caused the destruction of the cell integrity and wall structure of L. monocytogenes. The increase in conductivity and the leakage of intracellular biomacromolecules (nucleic acids and proteins) confirmed that limonene had an obvious effect on cell membrane permeability. The results of Propidium Iodide (PI) fluorescence staining were consistent with the results of the conductivity measurements. This indicated that limonene treatment caused damage to the L. monocytogenes cell membrane. Furthermore, the decrease in ATP content, ATPase (Na + K + -ATPase, Ca 2+ -ATPase) activity and respiratory chain complex activity indicated that limonene could hinder ATP synthesis by inhibiting the activity of the respiratory complex and ATPase. Finally, differential expression of proteins in the respiratory chain confirmed that limonene affected respiration and energy metabolism by inhibiting the function of the respiratory chain complex.Molecules 2020, 25, 33 2 of 15 terpenes in nature and is widely found in the volatile oils of various plants (black pepper, lemon and orange, etc.) [9]. Limonene has broad application prospects in antibacterial and food preservation due to its broad-spectrum bactericidal activity, safety, and low toxicity [10]. Moreover, D-limonene can significantly inhibit gram-negative and gram-positive bacteria as well as fungal activity [11]. In addition, many researchers have confirmed that D-limonene can effectively inhibit the growth of spoilage bacteria, such as Aspergillus niger, Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli [12,13]. Limonene, which is the main ingredient of lemon essential oil, was found to have antimicrobial activities against L. monocytogenes in minced beef meat [14]. However, few studies have investigated the antibacterial mechanism of limonene.The aims of this study were to determine the antibacterial susceptibility and its antibacterial mechanism of limonene against L. monocytogenes. The minimum inhibitory concentration (MIC) was used to evaluate the anti-L. monocytogenes susceptibility of limonene. The growth curves of the bacterial were determined for evaluating the effect of limonene on the growth and reproduction of L. monocytogenes. The mechanism of action of limonene was explored by analysing its influence on the cell morphology, membrane permeability and changes in the protein, nucleic acid, ATP, ATPase (Na + K + -ATPase, Ca 2+ -ATPase), respiratory chain complex I~V, and differential protein expression of the respiratory chain complex of L. monocytogenes.

“…Because of their richness in micronutrients needed for the growth of pathogenic germs that are harmful to humans (WCRF, 2018;Nohr et al, 2007), flesh foods represent an important source of foodborne diseases worldwide (Heredia et al, 2018). Actually, poultry is considered as the first source of Salmonella (SfAM, 2014), while this germ is known as the major zoonotic bacterium responsible for death related to foodborne illnesses in the united states (Mead et al, 1999) and one of the public health problems worldwide (WHO, 2018).…”

The current study aimed to determine the epidemiological profile of foodborne diseases associated with flesh foods during 2010-2016 in Morocco. A retrospective study of foodborne diseases caused by flesh foods recorded by the Moroccan anti-poison and pharmacovigilance center during 2010-2016. During this period, 2963 foodborne diseases related to flesh foods were declared to the center, in which 24.83% were registered in 2015, and 20.75% in 2013. Diseases occurred mostly in urban areas (67.06%). The major affected group's ages were adults (33.81%) and children (14.44%). The average patient's age was 25.09 ± 15.37 years. Male were the most vulnerable to infection (54.80%) with a sex ratio (male / female) of 1.72. The most incriminate flesh foods were respectively chicken (47.35%), aquatic products (30.94%) and red meat (16.57%). The high incidence rate was related to chicken skewers (3.55 per 100000 people), while the high fatality rate was associated with giblets (3.33%). Diseases due to the restauration outside home accounted for 58.15%. The majority of cases were collective (84.27%) and occurred significantly in spring (18.49%) and summer (14.51%). clinical symptoms were present in 67.19 % of cases, mostly moderate (81.77%) with four death cases corresponding to fatal condition. The high incidence rates were recorded in the regions of Sahara. Foodborne diseases are spreading progressively in Morocco, especially in summer and hot climates. The majority of these diseases are due to the consumption of contaminated flesh foods. Therefore, the responsible of food safety in Morocco must ensure the quality control of these foodstuffs.
