Evaluation of dipstick kit for detection of vibrio cholerae 01

ABSTRACT

Background:The kit Crystal VC is a Lateral Flow Imunochromatographic test for the qualitative determination of Lipopolysacharide (LPS) antigen of both V cholerae 01 and 0139, from stool specimens, using monoclonal antibodies specific to V. cholerae 01 and 0139 LPS. It does not include culturing the specimen and is performed without the need for sophisticated laboratory equipment. \r\n', u'Objectives: To evaluate the dipstick kit for detection of V. cholerae 01. Subjects and methods: A total of 65 stool specimens from diarrhea patients were tested to determine V. cholerae 01 by Crystal VC kit. \r\n', u'Results: The sensitivity of the 01 dipstick compared to culture was 93.7%, with a specificity of 87.7%. Crystal VC kit is simple, sensitivity, specific and does not require culturing procedures, making it suitable for direct detection of V. cholerae in clinical specimens. Also, the test only requires 10 minutes to complete.\r\n', u'Conclusions: The dipsticks test may be helpful in confirming clinically suspected cholera cases, especially during the start of an outbreak. Once a cholera outbreak has been confirmed, large scale preventive measures could be mobilized to minimize morbidity and mortality. \r\n', u'
