In a single-blinded study involving 120 patients neither the incidence nor severity of phlebitis observed with cephapirin and cephalothin was significantly different.

Eight cephalosporins were tested for their activity against methicillin-susceptible and methicillin-resistant, coagulase-negative staphylococci and for their resistance to beta-lactamase from methicillin-resistant, coagulase-negative staphylococci. Susceptibility testing by the agar plate method was evaluated for the effect of inoculum size and duration of incubation. Methicillin-susceptible, c...

Objective. To compare four different dry cow treatments (DCT) and establish their effectiveness in reducing intramammary infections (IIM). Materials and methods. DCTs included systemic tylosin (12g) alone or accompanied by cefapirine intramammary infusions and or an internal teat sealant. A total number of 278 cows at the end of lactation period were randomly assigned to one of 4 dry cow treatm...

A double-blind study with volunteers was performed to determine the incidence and severity of thrombophlebitis associated with cephalothin, cephapirin, cefamandole, and a water control. Although there were no statistical differences in the incidence of thrombophlebitis, cephalothin resulted in significantly more severe thrombophlebitis compared with the other agents.

Quarter milk samples from 51 purebred (Angus, Polled Hereford, and Simmental) and 69 crossbred (Angus x Simmental x Charolais three-way cross) beef cows were collected aseptically at three times during lactation to determine the prevalence of intramammary infection, milk somatic cell counts (SCC), and effects of infection on calf weight gain. Quarter infection prevalence was 13.1, 14.9, and 27....

Staphylococcus aureus intramammary infections (IMIs) have low cure rates using standard antibiotic treatment and increasing the duration of treatment usually improves therapeutic success. Chronic IMIs are thought to be caused by bacteria presenting a specific virulence phenotype that includes the capacity to produce greater amounts of biofilm. In this study, antibiotic susceptibility and biofil...

to evaluate the effect of intrauterine cephapirin on treatment of endometritis 39 holstein dairy cows that affected with postpartum endometritis were selected and randomly assigned to two experimental designs. in experiment 1, 6 out of 14 cows were 25 to 30 days after parturition were treated by intrauterine oxytetracycline. another 8 cows were treated by intrauterine cephapirin (metri-care). i...

Thirteen strains of the gram-negative, facultative phototrophic bacterium Rhodobacter sphaeroides were examined fro susceptibility to beta-lactam antibiotics. All strains were sensitive to the semisynthetic penicillins ampicillin, carbenicillin, oxacillin, cloxacillin, and methicillin, but 10 of the 13 strains were resistant to penicillin G, as well as a number of cephalosporins, such as cephal...
