A high-throughput method for the quantification of iron saturation in lactoferrin preparations.
Analytical and Bioanalytical Chemistry 405(15):5191 (2013)
Lactoferrin is considered as a part of the innate immune system that plays a crucial role in preventing bacterial growth, mostly via an iron sequestration mechanism. Recent data show that bovine lactoferrin prevents late-onset sepsis in preterm very low birth weight neonates by serving as an iro...
Bacterial infections of the lower genital tract in fertile and infertile women from the southeastern Poland.
Ginekologia polska 84(5):352 (2013)

Antibiotic resistance: a "dark side" of biofilm‑associated chronic infections.
Polskie archiwum medycyny wewnetrznej 123(6):309 (2013)
Bacteria may exist in nature in a planktonic form or in biofilms that allow bacteria to survive in an unfriendly microenvironment. Biofilm is a structured community of bacteria hidden in a self-produced polymeric matrix of polysaccharides, proteins, and extracellular DNA. Biofilm-growing bacteri...
Influence of taurine haloamines (TauCl and TauBr) on the development of Pseudomonas aeruginosa biofilm: a preliminary study.
Advances in Experimental Medicine and Biology 775:269 (2013)
Biofilms are consortia of microorganisms (sessile cells) that form on various surfaces including mucosal membranes or teeth. Bacterial biofilms cause many human infections such as chronic sinusitis, acne vulgaris, periodontal diseases, and chronic wounds. These infections are persistent as they ...
