Abstract

This study describes the influence of bioptivet GB on minimum inhibitory concentrations (MIC) for furazolidone of the intestinal E. coli flora of young broiler chickens after prophylactic treatment. From day 6 until day 15 one group of 50 birds received a diet containing 326 ppm furazolidone, another group of 75 birds served as non medicated control. Investigated E. coli had been isolated from cloacal swabs and from caecal contents. MIC of 1581 E. coli strains were determined by agar dilution test. MIC of furazolidone for the investigated strains ranged from 2 micrograms/ml to 64 micrograms/ml. For classification as "resistant" or "susceptible" limits of 16 micrograms/ml and 8 micrograms/ml respectively were used. Strains obtained from undosed birds mainly had MIC values of 4 micrograms/ml or 8 micrograms/ml, i.e. two or three times higher than MIC of E. coli ATCC 25 922, MIC values of 16 micrograms/ml or more were recorded only among isolates obtained from chickens which had received the drug. Administration of bioptivet GB resulted in a statistically significant increase in the average MIC. Statistically higher average MIC were recorded among isolates from cloacal swabs only during application of the drug. For strains from ca...Continue Reading

Allergy & Infectious Diseases (ASM)

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
