Animal model for determining the no-effect level of an antimicrobial drug on drug resistance in the lactose-fermenting enteric flora.
Mature beagles were fed a ground-meal diet containing 0, 2, or 10 mug of oxytetracycline per g for 44 days. The 10-mug/g diet resulted in a shift from a predominantly drug-susceptible population of enteric lactose-fermenting organisms to a multiply antibiotic-resistant population which peaked at 78% resistant organisms. Since a shift to drug-resistant organisms did not occur in the group fed 2 ...
متن کاملLactose-fermenting yeasts in yoghurt and their effect upon the product and the bacterial flora.
With the exception of certain sour milks such as kefir and koumiss, the presence of lactose-fermenting yeasts in dairy products is most undesirable because it results in gassy fermentation. Since the early days of microbiology, many lactosefermenting yeasts, both sporogenous and asporogenous, have been isolated. In most of the cases, however, the descriptions of these yeasts, viewed by present ...
متن کاملEffect of antibiotic treatment on the incidence of infectious drug resistance among intestinal lactose-fermenting bacteria isolated from burn patients.
Antibiotic-resistant lactose-fermenting bacteria were recovered from the feces of 20 of 25 burn patients studied. Of the Escherichia coli isolated from patients receiving antibiotic treatment, 81.5% were shown to be infectiously resistant; only 32% of the E. coli recovered from patients not receiving antibiotics were shown to be harboring R factors. Three resistance patterns, ampicillin-chloram...
متن کاملIncidence of infectious drug resistance among lactose-fermenting bacteria isolated from raw and treated sewage.
Raw and treated sewage samples were examined for antibiotic-resistant, lactose-fermenting bacteria. Approximately 1% of the total lactose-fermenting bacteria were multiply resistant. Of these organisms, 50% were capable of transferring all or part of their resistance to a drug-sensitive recipient. Only 43% of those isolated on media containing a single antibiotic were capable of resistance tran...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
