epidemiology of antimicrobial resistant cholera in kenya and east africa.	strains of vibrio cholerae o1, el tor resistant to multiple antimicrobial agents, were isolated in kenya between 1982 and 1985. strains of serotype ogawa were resistant to tetracycline, ampicillin, and trimethoprim/sulfamethoxazole. resistance was mediated in all instances by a plasmid ca 100 md of incompatibility group c. based on analysis of restriction endonuclease digests, all ogawa isolates had an identical resistance plasmid. this plasmid differed from plasmids in resistant v. cholerae o1 ...	1988	3195696
the distribution of podosomes in osteoclasts cultured on bone laminae: effect of retinol.	osteoclasts, isolated and purified from the medullary bone of calcium-deficient egg-laying hens, adhere to glass coverslips in vitro by means of specialized protrusions of the ventral membrane, denoted podosomes. these structures represent dotlike close-contact adhesion sites in which most cytoskeletal proteins involved in linking the plasma membrane to microfilaments are organized according to a specific and previously described pattern also shared by many oncogene-transformed cells. we show no ...	1988	3195364
