Construction and in vitro characterisation of aroA defective ( aroA Δ) mutant Salmonella Infantis
Abstract Poultry vaccine programs are important for control of Salmonella infections. Although there are vaccines for Salmonella Enteritidis, Salmonella Typhimurium and Salmonella Typhi, there are no vaccines for Salmonella Infantis which has an increased rate in the world. In this study, it was aimed to generate aroA gene deleted mutant bacteria for the constitution of S. Infantis vaccine prototype and the in vitro characterisation of this bacterium. S. Infantis auxotrophic mutant...

Proteomics-based discrimination of differentially expressed proteins in antibiotic-sensitive and antibiotic-resistant Salmonella Typhimurium, Klebsiella pneumoniae , and Staphylococcus aureus
Abstract This study was designed to compare the differentially expressed proteins between antibiotic-sensitive and antibiotic-resistant Salmonella Typhimurium, Klebsiella pneumonia, and Staphylococcus aureus. The susceptibilities of wild-type (WT), ciprofloxacin (CIP) and/or oxacillin (OXA)-induced, and clinically isolated resistant (CCARM) S. Typhimurium (STWT, STCIP, and STCCARM), K. pneumoniae (KPWT, KPCIP, and KPCCARM), and S. aureus (SAWT, SACIP, SAOXA, and SACCARM) to antibiotics...

Investigation of the effect of different environmental conditions on biofilm structure of Salmonella enterica serotype Virchow via FTIR spectroscopy
Abstract This study aims to describe the content of polymeric matrix components under different incubation temperatures and pH levels. Optimal biofilm production of 15 S. Virchow isolates occurred following the incubation in LB−NaCl for 72 h, at pH 6.6 and 20 °C. The expression of csgA, csgD, adrA and bcsA genes at 20 °C, 25 °C and 30 °C in S. Virchow DMC18 was analyzed, and it was discovered that the maximum production of cellulose and curli fimbriae occurred at 20 °C. The physical...

Bacteriocinogenic Lactococcus lactis subsp. lactis 3MT isolated from freshwater Nile Tilapia: isolation, safety traits, bacteriocin characterisation, and application for biopreservation in fish pâté
Abstract This work was aimed to screen bacteriocin-producing LAB from freshwater fish, select a prominent strain and evaluate its safety, characterise the bacteriocin produced, and evaluate its potential to be used as biopreservatives. Isolate 3MT showed the ability to produce bacteriocin-like substances and was identified as Lactococcus lactis subsp. lactis. This strain proved to be free from virulence factors as well as biogenic amine production and antibiotic resistance patterns....

Isolation and identification of the Raoultella ornithinolytica -ZK4 degrading pyrethroid pesticides within soil sediment from an abandoned pesticide plant
Abstract We examined how Raoultella ornithinolytica-ZK4 degraded pyrethroid pesticides within soil sediment from an abandoned pesticide plant. Lambda-cypermethrin and deltamethrin are two pyrethroid insecticides with high insecticidal activity and a wide range of applications. However, their increased use has raised concerns regarding toxicity and accumulation. We isolated a strain of ZK4 (Raoultella ornithinolytica-ZK4) from soil taken from a channel that surrounded a pesticide...
