SUMMARYThe majority (85%) of shigella isolated in 1980 and 1981 in Korea wereShigella flexneri, the others wereSh. sonnei(14%) with only a small number ofSh. dysenteriae. Only 14 of the 459 strains of shigella isolated were susceptible to all 12 drugs tested, and 445 were resistant to three or more drugs. Strains multiply resistant to the six drugs, chloramphenicol (Cm), tetracycline (Tc), streptomycin (Sm), sulfisomidine (Su), ampicillin (Ap) and trimethoprim (Tp) were most frequently encountered, followed by those resistant to Cm, Tc, Sm, Su and Tp. The complete patterns of resistance to drugs except nalidixic acid and rifampin in approximately 73% of drug-resistant strains were co-transferred toEscherichia coliby conjugation, indicating that the resistance was R plasmid-mediated. Randomly selected R plasmids conferring various patterns of resistance markers were tested for the incompatibility groups, and almost all of them were classified intoIncFII. Two of three R plasmids conferring resistance to Cm, Tc, Sm and Su were classified intoIncB and one toIncFII. Two R types with resistance markers of Cm, Tc, Sm and Ap were not classified with our standard plasmids used.

SummaryA total of 2973Escherichia coli, isolated from six different groups of animals, were examined for their ability to ferment adonitol, dulcitol, raffinose, rhamnose and sorbose in solid media. Twenty-nine fermentation patterns were recorded although 2443 (82%) of theE. colibelonged to seven of the 32 possible biotypes. Ninety-six O-serotypes were identified within the 2973E. coli.The number of O-serotypes represented in the 15 most common biotypes ranged from three to 15. Sero types O8 and O9 were found most commonly in the different groups of animals and several biotypes amongst these two O-serotypes were identified in two or more groups of the animals. The ability of theE. colito metabolize aesculin, ornithine, salicin and sucrose was also assessed. These tests proved less reproducible and were not included in the primary biotyping scheme although their use allowed the enumeration of additional biotypes. The application of biotyping to the study of the ecology of drug-resistant strains ofE. coliin five situations is briefly presented.

Tuberculosis (TB) remains one of the most difficult ailments to control in the world today. The emergence of drug resistant strains has made previously effective and affordable remedies less effective (There are more than twenty drugs that are currently used for the treatment of TB and almost all of them were developed some years ago. The drugs are used in differing combinations in different circumstances, so that for example some TB drugs are only used for the treatment of new patients who are very unlikely to have resistance to any of the TB drugs). This has made the search for new medicines from local traditional medicines. The specific objectives of this study were to identify plant species used in the treatment of TB, parts used, their methods of preparation and administration. The present study was conducted in the central tarai region of Kumaun, Uttarakhand in the year 2008-2011. Total fifteen plant species were found to be used to cure tuberculosis. The different use of Adhatoda vasica was reported first time from the study area. Species Albizia lebbeck, Bauhinia variegata, Baliospermum montanum, Sida rhombifolia, Withania somnifera, Asclepias curassavica, Echinops echinatus, and Saccharum spontaneum were reported first time of the study area.
