Summary
Laboratory workers
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Healthcare workers' hands are key in spreading antimicrobial resistance.
- The role of laboratory workers (LWs) in this spread is less understood.
- Jewelry, like wedding rings, can harbor microorganisms.
Purpose of the Study:
- To investigate biofilm-forming staphylococci on LWs' jewelry rings.
- To determine the antimicrobial susceptibility patterns of these staphylococci.
- To assess the potential role of LWs' jewelry in microbial transmission.
Main Methods:
- Collected samples from 79 LWs' wedding rings in Belgrade, Serbia.
- Used the rolling method to detect bacteria on rings post-hand washing.
- Analyzed bacterial species, colony-forming units (CFU), antimicrobial resistance, and biofilm production in vitro.
Main Results:
- Staphylococci were found on 60.8% of wedding rings.
- All recovered staphylococci strains exhibited biofilm-forming capacity.
- High resistance rates to penicillin, tetracycline, and erythromycin were observed; 41.7% were multidrug-resistant.
Conclusions:
- LWs' wedding rings are colonized by biofilm-forming, multidrug-resistant staphylococci.
- These rings can act as reservoirs for spreading microorganisms and antimicrobial resistance.
- This study is the first to highlight this issue specifically in laboratory workers.

164
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

01:19Handwashing II: Pre-procedure and Initial Procedure Steps
989
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

01:30Bacterial Signaling
33.5K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
