A brief account is given of the morphology, biochemistry and serology of Salmonella braenderup isolated from mussel meat, obtained from fish markets in Calicut, India. Possible implications regarding human salmonellosis are also considered

Is ation braenderup 7: e, h: e, 
The serotype Salmonella braenderup was 
isolated from a sample of mussel meat colle-
cted from Calicut fish market on 25th March 
1986. The method suggested by AOAC 
(197 5) was followed for the detection of 
Table 1. Morphological, biochemical and

Sabnonella. One strain of Salmonella iso-
lated from this sample was sent to the National 
Salmonella and Escherichia Centre at Kasauli 
and was identified to be S. braenderup. A 
final report on the identification was received 
on 13th May 1986. In India, this serotype 
has been isolated only m two prev,ous cases 
and both were from human sources exhi-
biting disease sysrnptoms (personal communi-
cation from the National Salmonella Centre). 
The chances of association of this serotype 
in human salmonellosis is thus evident. 
Centres for Disease Control, U.S. Depart-
ment of Health and Human Services (1981) 
have also reported isolation of this serotype 
from human cases. The biochemical pro-
perties of S. braenderup were similar to that 
of typical Salmonella (Table 1). 
The authors are thankful to the National Salmo-
nella and Escherichia Centre, Central Research Insti-
tute, Kasauli, for serotyping the strain. The authors 
are grateful to Shri M. R. Nair, Director, Central 
Institute of Fisheries Technology, Cochin -29, for 
his kind permission to publish this note. The tech-
nical assistance given by Shri M. K. Sasidharan of 
quality control section, CIFT is also acknowledged.
