| temporal shifts in the dominance of serotypes of shigella dysenteriae from 1999 to 2002 in dhaka, bangladesh. | a total of 358 shigella dysenteriae strains isolated from patients attending the dhaka treatment center of the international centre for diarrheal disease research, bangladesh, between the years 1999 and 2002 were included in this study. s. dysenteriae type 1, the dominant serotype in 1999 (76.4%), declined to 6.5% in 2002. on the other hand, s. dysenteriae types 2 to 12 were isolated with increasing frequencies of 19, 67, 73.5, and 87% in 1999, 2000, 2001, and 2002, respectively. of these, types ... | 2003 | 14605138 |
| antimicrobial interactions of microbial species involved in the fermentation of cassava dough into agbelima with particular reference to the inhibitory effect of lactic acid bacteria on enteric pathogens. | lactic acid bacteria, bacillus species and yeasts are involved in the fermentation of cassava dough into agbelima. microbial interactions within and between these groups of microorganisms were investigated in addition to the survival of five enteric pathogens inoculated into agbelima under various conditions. nine out of 10 cultures of lactic acid bacteria isolated at the end of agbelima fermentation showed inhibitory effect against 10 cultures of lactic acid bacteria isolated at the start of fe ... | 2003 | 14580972 |
| acute lymphangitis treated by moxibustion with garlic in 118 cases. | tcm holds that acute lymphangitis is pathogenically caused by the accumulated internal fire and toxicity, and the external skin injury-induced infection, leading to toxicity going upward along the meridians. the treatment should be given to clear away heat and toxin. blood letting by a three-edged needle may promote qi and blood circulation and remove the toxic heat. garlic has the function of antagonizing staphylococcus aureus, bacillus dysenteriae and various kinds of bacteria. since the volat ... | 2003 | 14535186 |
