| determination of toxinotypes of environmental clostridium perfringens by polymerase chain reaction. | toxinotype of clostridium perfringens (cp) isolates collected from the bernam river, selangor river and tengi canal between april 2007 and january 2008 were determined by polymerase chain reaction (pcr) using published primers. all the 147 isolates were toxinotype type a, harbouring the alpha toxin gene. in addition, 5 of the isolates also had the enterotoxin (cpe) gene. | 2011 | 21602783 |
| clostridium perfringens and sulphite reducing clostridia densities in selected tropical malaysian rivers. | clostridium perfringens (cp) and sulphite reducing clostridia (src) densities in the selangor river, bernam river and tengi river canal were examined between april 2007 and january 2008. water samples were taken from two or three locations along each river, using either depth-integration or grab sampling methods. the downstream sampling site of the selangor river, rantau panjang, reported the highest arithmetic mean of cp and src densities (583.45 and 8,120.08 cfu/100 ml, respectively). both cp ... | 2012 | 23082563 |
