Asthma in workers manufacturing cephalosporins.

complex describes a hallux valgus which touches or overrides the second toe and is associated with an inflamed bursa around the metatarsal joint. Other toe deformities such as overriding and clawing were common but associated with inflammation over joints only in four patients. Most patients had more than one foot problem; the range was from none to eight problems with a modal value of between ...

Dissociated resistance among cephalosporins.

When disks containing cefuroxime (CXM) or HR 756 (756) were placed next to cefoxitin (FOX) on plates inoculated with Enterobacter resistant to FOX, there was marked flattening of the zones of inhibition produced by CXM or 756, but colonies growing near the CXM or 756 disks were found to be fully susceptible to these drugs on retesting. In contrast, when a checkerboard titration with CXM or 756 ...

Sensitivity tests with cephalosporins.

The sensitivity of 127 strains of miscellaneous Gram-negative bacilli to various cephalosporins was determined by three methods. Disc tests with cephaloridine (CLOR), cephalothin (CTIN) and cephalexin (CLEX) made most strains of beta-lactamase-producing Escherichia coli appear sensitive. Eight cephalosporins were tested by the agar break-point method using concentrations of 16 and 4 mg/l for al...

Penicillins and cephalosporins.

Resemblances and differences between the penicillins (I) and cephalosporins (II) are considered from a chemical and biochemical point of view.
