Rapid and sensitive methods for the detection of pathogenic microorganisms are required to monitor contamination in milk and assure public health. A colorimetric antibody-based stack pad system (biosensor) was developed to detect microbiological content of milk based on nitrocellulose membranes. This modification of the lateral flow immunoassay uses a multiple-membrane biosensor containing (from top to bottom): a sample pad, a conjugation pad (with anti-Escherichia coli antibodies conjugated to horseradish peroxidase), six Escherichia coli strain DH5α bacteria-blocking layers and an absorption pad with dry substrate.

is an emerging pathogen that causes meningitis, bacteremia, sepsis, and necrotizing enterocolitis in premature infants. Strain Cr268 was isolated from imported powdered infant formula in 2009 during routine microbial examination according to ISO-22964 ("Microbiology of the food chain-horizontal method for the detection of spp.").

To understand the effects of the interaction between Mycoplasma and cells on the host cellular function, it is important to elucidate the influences of infection of cells with Mycoplasma on nuclear enzymes such as DNA Topoisomerase type I (Topo I). Human Topo I participates in DNA transaction processes and is the target of anti-cancer drugs, the camptothecins (CPTs). Here we investigated the mechanism by which infection of human tumor cells with Mycoplasma fermentans affects the activity and expression of cellular Topo I, and the anti-cancer efficacy of CPT.

Deep gastrointestinal involvement in endometriosis is characterised by fibrous, retractile thickening of the intestinal wall. The most common location is the upper rectum, in contiguity with a lesion of the torus uterinus. As part of a preoperative assessment, it is essential to establish an accurate and exhaustive map of intestinal lesions so that the surgeon can plan his actions.
