HOSPITAL MEDICAL STAFF BY-LAWS: AN INSTRUMENT FOR SELF-GOVERNMENT.

Hospital medical staff by-laws are important. By them the governing board of a hospital can and does confer on the medical staff the power to set up a form of organization by which that staff can give assurance of quality hospital medical care. The form of medical staff organization is patterned on familiar concepts of democratic self-government as we know it on this continent. Within the ordered society of the hospital medical staff, as in society at large, there is control of citizenship, classification of citizens as to their citizen rights, licence to do differing kinds of work, election of representatives, definition of rules for conduct, application of the cabinet principle, law enforcement by appointed judges, the right of appeal and, importantly, incentive for voluntary effort. Traditional professional freedom, self-determination and voluntary association of colleagues are guarded by this method of hospital conduct which is unique to the voluntary hospital system on this continent. Knowledge of the democratic process and of the motivation required to make it work well are essential for its preservation.

COMPARISON OF TWO METHODS FOR THE ISOLATION OF SALMONELLAE FROM IMPORTED FOODS.

Two methods for the detection of salmonellae in foods were compared in 179 imported meat and egg samples. The number of positive samples and replications, and the number of strains and kinds of serotypes were statistically comparable by both the direct enrichment method of the Food Hygiene Laboratory in England, and the pre-enrichment method devised for processed foods in the United States. Boneless frozen beef, veal, and horsemeat imported from five countries for consumption in England were found to have salmonellae present in 48 of 116 (41%) samples. Dried egg products imported from three countries were observed to have salmonellae in 10 of 63 (16%) samples. The high incidence of salmonellae isolated from imported foods illustrated the existence of an international health hazard resulting from the continuous introduction of exogenous strains of pathogenic microorganisms on a large scale.

Isolation of Salmonellae from food samples. IV. Comparison of methods of enrichment.

A comparison of various methods of enhancing frequency of Salmonella isolations revealed that inoculation of a second enrichment broth, with culture from the first, was no improvement over the single direct enrichment method. It was inferior to centrifugation. Selenite was observed to produce more positive isolations at 48 hr than at 24. No change occurred in tetrathionate. Reconstitution of dried albumen with water produced a significant increase in isolations over direct inoculation of enrichment broth in the case of tetrathionate but not selenite broth.Pre-enrichment in lactose broth before inoculation of enrichment media was vastly superior to reconstitution in water for both enrichment broths. A comparison of results obtained using dulcitol, mannitol, lactose and carbohydrate-free purple broths in pre-enrichment indicated that the carbohydrate added was immaterial.

Isolation of Salmonellae from food samples. V. Determination of the method of choice for enumeration of Salmonella.

Comparison of three methods by which salmonellae may be isolated and enumerated from dried albumen, direct inoculation of enrichment media, centrifugation of samples, and pre-enrichment in noninhibitory media, reveals pre-enrichment to be the method of choice. The superiority of pre-enrichment manifests itself in replicate aliquots of the same sample by producing a statistically significant increase in numbers of isolations of salmonellae and in empirical use with various albumen samples by consistently higher values of most probable numbers (MPN). The primary factor involved in this superiority appears to be the greater ability of small numbers of salmonellae to initiate growth in the nonselective mannitol purple sugar broth than in the inhibitory enrichment media. The method of analysis recommended entails inoculation of mannitol broth pre-enrichment medium, transfer of 24-hr culture aliquots to tetrathionate broth, and streaking on brilliant green agar for isolation of salmonellae.
