Custom made total hip replacement--necessary or not?

Indication and technical requirements analyses for custom made THR have been made. Indications for the use of custom made THR and the results achieved have been assessed according to the available literature and compared to the results of standard THR. There is a significant divergence in indications, late results and production costs.

Correlation of teichoic acid D-alanyl esterification with the expression of methicillin resistance in Staphylococcus aureus.

Methicillin-susceptible and -resistant isolates of Staphylococcus aureus, including a teichoic acid-deficient mutant, were examined under varying physiological conditions for their degree of teichoic acid and lipoteichoic acid D-alanyl esterification. Methicillin-resistant strains grown in the presence of methicillin and NaCl possessed significantly decreased amounts of D-alanyl ester when compared with methicillin-susceptible isolates. These strains also exhibited reduced autolysis.

Evidence for association of bacteriocinogenic activity with membrane vesicles of Thermus rubens.

Thermus rubens has previously been reported to exhibit bacteriocin-like antagonism against other members of the genus Thermus when assayed via the deferred antagonism technique. Bacteriocin activity was not detectable in various age batch culture supernatants assayed by simple spotting procedures. Successful cell-free isolation was accomplished by way of a procedure employing French press disruption of T.

Bacteriocinlike Activity within the Genus Thermus.

Members of the genus Thermus were examined for the presence of bacteriocinlike inhibitory activity. Testing was done by the deferred antagonism technique. Antagonistic activity, as evidenced by zones of inhibition, was expressed by Thermus rubens against all other Thermus strains tested.

Screening method for recovery of methicillin-resistant Staphylococcus aureus from primary plates.

A study designed to screen for the presence of methicillin-resistant Staphylococcus aureus from primary plates was conducted from 1 January to 1 September 1985 in a small community hospital. The screening method used a plate of lipovitellin salt mannitol agar and a 4-microgram oxacillin disk incubated at 30 degrees C. Growth of yellow colonies, typical of S.
