The fish's primary immune system in epidermis produces the mucosal layer as a surplus mechanism to cover the surface of the fish's body against infections. In addition to its physical functions such as reducing water friction and protecting against abrasion, it contains biologically active constituents, which is the first line of defense against pathogens. During the past years, the antimicrobi...

Antimicrobial resistance (AMR) of foodborne pathogens is public health concern, especially in developing countries such as Zambia. This study was undertaken to determine the antimicrobial profiles Escherichia coli (E. coli) and Salmonella isolated from retail broiler chicken carcasses purchased open markets supermarkets A total 189 E. five isolates were isolated. Identification confirmation don...

Background: Lactic acid bacteria interfere to improve the taste of food products and and to prevent the growth of food spoilage organisms and pathogens with producing antimicrobial substances called bacteriocin. To study the antagonistic effect of isolated Lactobacillus from soil where native yogurt is processed against pathogenic bacteria is the purpose of this study. Methods: In this cross-s...

The antimicrobial effect of the mastic tree (Pistacia atlantica) under in vitro conditions has been reported. Therefore, it is of interest to evaluate the effect of the plant leaf extract (aqueous) on bacterial load in mouth and saliva. The leaf of the Pistacia atlantica plant was collected and cleaned, dried at 40⁰c and then powdered. The extraction was carried out using the maceration method ...

A total of 24 strains of the Mycobacterium fortuitum complex were tested for susceptibility to antimicrobial agents by the disk diffusion and agar dilution techniques. By comparing zones of inhibition obtained with the disk diffusion technique with results of minimal inhibitory concentration determinations, it was shown that disk diffusion results could predict in vitro susceptibility to select...

To evaluate the occurrence of out-of acceptable ranges and accuracy of antimicrobial susceptibility tests, we applied a new statistical tool to the Inter-Laboratory Quality Control Program established by the Kyushu Quality Control Research Group. First, we defined acceptable ranges of minimum inhibitory concentration (MIC) for broth microdilution tests and inhibitory zone diameter for disk diff...

The utility of Etest for antimicrobial susceptibility testing of Yersinia pestis was evaluated in comparison with broth microdilution and disk diffusion for eight agents. Four laboratories tested 26 diverse strains and found Etest to be reliable for testing antimicrobial agents used to treat Y. pestis, except for chloramphenicol and trimethoprim-sulfamethoxazole. Disk diffusion testing is not r...

Essential oils (EOs) are aromatic oily liquids extracted from different parts of specific plants, well known especially for their aromatic and antibacterial properties. Nowadays, EOs are exploited in the food sector mainly for their aromatic properties. Thanks to their antimicrobial activity, however, they could also be used as additives to increase the safety and the shelf-life of food product...
