| emergence of multi-drug resistance among beta-lactamase producing salmonella. | multi-drug resistant strains of salmonella isolated from blood and bone marrow cultures of pyrexial patients received from physicians, hospitals and different clinics were studied from may to november, 1993. of 2143 samples collected, 424(20%) cases yielded the growth of different organisms. out of these 266(63%) were positive for salmonella strains. the strains isolated were salmonella typhi 239(90%) and salmonella paratyphi a 27(10%). two hundred twenty (82%) strains of salmonella showed incre ... | 1994 | 7830302 |
| molecular recognition of a salmonella trisaccharide epitope by monoclonal antibody se155-4. | the binding site of monoclonal antibody se155-4, which has been the object of successful crystallographic and antibody-engineering studies, is shown by solid-phase immunoassays to be complementary to a branched trisaccharide, alpha-d-galp(1-->2) [alpha-d-abep(1-->3)]-alpha-d-manp(1, rather than to the tetrasaccharide repeating unit alpha-d-galp(1-->2) [alpha-d-abep(1-->3)]-alpha-d-manp(1-->4) alpha-l-rhap(1- of the bacterial antigen. specificity for the 3,6-dideoxy-d-xylo-hexose (3,6-dideoxy-d-g ... | 1994 | 7513555 |
| immunochemistry of salmonella o-antigens: specificity of rabbit antibodies against the o-antigen 2 determinant elicited by whole bacteria and 3-o-alpha-paratopyranosyl-d-mannopyranosyl conjugated to bovine serum albumin. | the binding specificities of antibodies directed against the salmonella sero-group a-specific o-antigen 2 determinant were characterized by precipitation-inhibition and enzyme-linked immunosorbent assay inhibition tests. two different antigen o-2-specific antisera were investigated: one conventional factor o-2 serum (elicited by whole heat-killed salmonella paratyphi a bacteria) and another elicited by the synthetic disaccharide 3-o-a-paratopyranosyl-d-mannopyranosyl (formula: see text) covalent ... | 1980 | 6985605 |

| survivability of salmonella paratyphi b var java on experimentally infected cockroaches. | cockroaches are inhabitant of sewers and frequent visitors of kitchen and stores in the night to feed on left over. it is liable to disseminate a number of pathogens by contaminating kitchen surface, feeding vessels and food items left open. salmonella paratyphi b var java a common pathogen of man and animal was used in the study to evaluate its survival and excretion in cockroaches. the host when fed on semisolid feed containing 1 x 10(7) cfu of s. paratyphi b var java g-1, it was found that th ... | 1995 | 7558200 |
