The stools of 97 children with acute gastroenteritis, attending a private paediatric clinic, were studied for infectious agents. Putative pathogenic microorganisms were identified in 47 cases (48.5%). Food poisoning Salmonella was the most common bacteria detected, 25 cases (25.8%). Rotavirus was present in 9 cases (9.2%). Interview of the parents and care-persons revealed a general lack of knowledge in the proper cleaning and sterilisation of milk bottles, rubber teats and pacifiers. In 44 households there were at least one animal kept and there were positive bacterial isolates from 47% of such households. However, positive isolates were found in only 26% of households with no kept animals. The implications of these findings are discussed. (Copied from article).
Human saliva contains a large number of proteins which can be separated using polyacrylamide gel electrophoresis (PAGE). In this study the protein profiles of whole saliva of diabetic and non-diabetic were compared. Considerable variations between individuals in the protein profiles were observed. The saliva from diabetic patients appeared to have more of proline-rich protein bands in the molecular weight region below 56 KOa. Further investigations using individual gland saliva should be carried out.
