abstract

the objective of the present study was to determine whether there was an association between the in vitro antimicrobial susceptibility test results of subclinical mastitis pathogens and bacteriological outcomes of intramammary treatments using cefquinome. a total of 110 intramammary pathogens from 51 cows were assessed in this study. most intramammary infections were due to coagulase-negative staphylococci, environmental streptococci, and coliforms. the antimicrobial susceptibility to cefquinome was determined using the kirby-bauer disc diffusion method. bacteriological cure rates for the sensitive, intermediate, and resistant isolates in the standard treatment group (three intramammary infusions of 75 mg cefquinome at 16 h intervals) were 82.4%, 90%, and 87.5%, respectively. these figures in the extended treatment group (six intramammary infusions of 75 mg cefquinome at 16 h intervals) were 83.3%, 100%, and 100%, respectively. treatment outcomes were not associated with the results of sensitivity tests in the standard group. however, in the extended group, the probability of a bacteriological cure was lower in quarters from which cefquinome-sensitive pathogens were isolated than the quarters from which intermediate or resistant pathogens were isolated. based on this study, the kirby-bauer susceptibility test result is a poor predictor for the bacteriological cure of subclinical mastitis treated with intramammary cefquinome.

Relationship between in vitroantimicrobial sensitivity of bovine subclinical mastitis isolates and treatment outcome in lactating dairy cows

The objective of the present study was to determine whether there was an association between the in vitroantimicrobial sensitivity test results of subclinical mastitis pathogensand bacteriological cure following intramammary treatment using a combination of nafcillin, penicillin, and streptomycin (NPS). Eighty-six intramammary pathogens from 43 cows were examined inthis study. Most intramammary...

a comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
