Background: The assessment of the bacteriological quality of coastal marine waters through the search of Escherichia coli as an indicator of fecal pollution is a topic of public concern.
The microscopic cord formation is a characteristic property of the species of Mycobacterium tuberculosis complex (MTC). This feature is used as screening method of MTC and detection of drug resistant tuberculosis in law resource settings. The presence of true cording in M. abscessus poses a challenge for identification of MTC based on the cord formation.
Entamoeba histolytica is a cosmopolitan, parasitic protozoan of human large intestine, which is a causative agent of amoebiasis. Amoebiasis manifests with persistent diarrhea containing mucus or blood, accompanied by abdominal pain, flatulence, nausea and fever. In some cases amoebas may travel through the bloodstream from the intestine to the liver or to other organs, causing multiple abscesses.
The bacterial planktonic growth and the removal of bacterial cells grown on polypropylene surface coated with covalently immobilized proteases (subtilisin Carlsberg or a-chymotrypsin) was investigated for Enterococcus hirae, Staphyloccocus epidermidis and Eschericha coli. Immobilization of both proteases on plasma-treated polypropylene was carried out using as cross-linking agent i) glutaraldehyde or ii) N'-diisopropylcarbodiimide and N-hydroxysuccinimide.
Introduction: Due to the emergence of multidrug/extensively drug-resistant TB and the lack of new anti-TB drugs, tracing the infectious source and monitoring the transmission of drug-resistant TB strains have become critically important.
