“…The inner spore membrane, the peptidoglycan cortex, and the outer protein coat surround the dehydrated spore core, with the cortex playing a crucial role in the preservation of resistance 13 . Also, some bacteria such as Lactobacillus inhibit the growth of gram-negative bacteria 14 . In contrast, the studies of (15,16) mentioned that the negative bacteria are prevalent within the washing clothes and dishwasher machine community as they are more resistant to detergents (without bleaching agent), while the Gram positive bacteria are more resistant to high temperatures.…”

This study aimed to isolate, molecular identify, and evaluate the antimicrobial activity of the three commercial types of household detergents; Persil (P), Arial (A), and Peros (Pe) in both forms of gel liquid and (Tate ) powder and antibiotics susceptibility test to assessed against isolates from used washing machines in Mosul city/ Iraq. A total of 46 bacterial isolates were isolated. Five isolates were designated as Kh-Am1, Kh-Am4 from the Drum part, Kh-Am3, Kh-Am6 from the Rubber door seal part and Kh-Am5 from Drain dictum; these isolates were selected for molecular identification by 16S rRNA. The 16S rRNA gene of Kh-Am1, Kh-Am3, Kh-Am4, Kh-Am5 and Kh-Am6. The disc agar diffusion method was adopted for each selected isolate using stock and diluted concentrations. After incubation at 37ₒC for 24 hours, inhibition of Aerea was recorded. The results showed that the powder and gel form detergent stock solution has more inhibitory efficacy for the assayed isolates than dilutions. Susceptibility to antibiotics assay revealed that almost all the selected isolates were resistant. Even though infectious strains were not found, opportunistic pathogens were detected. However, because many bacteria have been detected in wash water, washing items at home with it may result in microbial contamination. Keywords: Washing machine bacteria, Washing machine environment, Detergents effect on bacteria, Antibiotic Susceptibility of washing machine bacteria.

in recent years, a number of studies have shown a close relationship between broiler performance, health and the gastrointestinal microbiota. However, taking the complexity and biodiversity of the micro-ecosystem into consideration, a manipulation of the microbiota in a way that is profitable both for the host bird and for the farmer seems a difficult goal to achieve. Bacteriocins are extracellular proteinaceous compounds, synthesized by many bacterial species. Due to their different bacteriostatic effects, they have been used in human nutrition for decades. However, limited information is available regarding their effects in poultry, even though that similar mode of action as in other animals is possible. therefore, the aim of the present review is to discuss present bacteriocin classification, mode of action and their potential role in poultry nutrition.
