Terminal subculture of blood cultures using a multipoint inoculator device.

A multipoint inoculator for petri dishes.

In recent years, rapid testing of pure cultures of bacteria for biochemical and physiological characters has been a point of great interest to clinicians and to microbial geneticists and taxonomists. The replicate plate technique (J. Lederberg and E. M. Lederberg, J. Bacteriol. 63:399, 1952), although extremely useful and widely employed, has certain disadvantages, particularly with cultures ha...

Evaluation of Mast-ID 15 system for identification of fresh clinical isolates of Enterobacteriaceae and Acinetobacter.

AIMS To assess the accuracy of the Mast-ID 15 system compared with API 20 E for the identification of stock and fresh clinical strains of Enterobacteriaceae and Acinetobacter spp; to compare the accuracy of 19 pin and 36 pin multipoint inoculator heads. METHODS One hundred frozen stock cultures of Enterobacteriaceae and Acinetobacter spp which had previously been identified by the API 20E wer...

Technique for the culture and direct sensitivity testing or large numbers of urine specimens.

A technique was required for batch culturing and direct sensitivity testing of urine specimens to reduce increasing demands on laboratory services. A comparison was made between the filter paper strip method and multipoint inoculator technique using a Denley inoculator (Denley Ltd, Billingshurst, Sussex). The results showed that multipoint inoculation was a rapid, economical, and reliable metho...

Improved automatic inoculator for bacterial cultures.

A simple automatic inoculator which allows the simultaneous inoculation of several cultures with identical or different inocula is described. The use of Teflon spaghetti tubing allows great flexibility in handling and placing of components. The inoculator can be adapted to handle aerobic and anaerobic bacteria.
