Bu çalışma, süt ürünleri proses hatlarından izole edilen hem gram (-) de (+) biyofilm üreticisi bakterilerin QS sinyallerini göstermeyi amaçlamıştır. sinyallerinin profilini ve kimyasal bileşimini tanımlanması, mikrobiyal direnç gelişimi oluşumunun kontrolü için önemli bir faktördür. Özellikle izolatların olağan dışı davranışlarına odaklanılmıştır. İzolatların uzun zincirli AHL sinyalleri (C14-...

background and objective: probiotics are live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance, producing metabolites which inhibit the colonization or growth of other microorganisms or by competing with them for resources such as nutrients or space. the aim of this study was to investigate the probiotic properties of candida fam...

OBJECTIVE To investigate the virulence factors including hemolysin production, β-lactamase production, and biofilm formation. Antimicrobial resistance and plasmid content of 20 Escherichia coli isolates obtained from feces and Tigris water were screened. METHODS Ten clinical and ten environmental E. coli isolates were collected from children diarrhea and swim areas on Tigris River in Baghdad ...

Objectives: The emergence of carbapenem resistance in biofilm producer Gram-negative bacteria poses a substantial challenge to manage infections. This study aimed evaluate production and molecular characterization rods. Methods: Total 46 were isolated from various clinical samples, including blood, CSF, urine, sputum, saliva, tracheal secretion, pus. Following the standard guidelines for bacter...

Ecosystems can undergo sudden shifts to undesirable states, but recent studies with simple single-species ecosystems have demonstrated that advance warning can be provided by the slowing down of population dynamics near a tipping point. However, it is unclear how this 'critical slowing down' will manifest in ecosystems with strong interactions between their components. Here we probe the dynamic...

Objective We evaluated biofilm production ability (BPA) of Streptococcus agalactiae isolates from companion animals/humans and clarified the relationship between BPA populations other microbiological features. Methods Companion animal-/human-origin were collected with host information. measured using crystal violet staining, via virulence-associated gene profiling (hylB-pavA-pilB-spb1-srtC1-brp...

In our first two columns, we described innovative practices that Advanced Practices Council (APC) members shared with their colleagues at recent meetings. In this column, we describe the ideas that Jim Tosone, a long-standing APC member, shared at the October APC meeting. A contributor to the recently published “Complete Idiot’s Guide to the U.S. Constitution,” Tosone explained how understandin...
