A cooperative MLT program between a community college and a university.

In 1991 the University of Utah collaborated with Salt Lake Community College to establish a jointly sponsored Medical Laboratory Technician (MLT) program. With documented need for MLTs in Utah and surrounding states, both institutions combined their resources to create an associate degree program that neither institution could offer alone. The first academic year of prerequisite science and liberal education courses are completed at the Community College followed by a second year of professional didactic and laboratory courses taught by faculty of the Medical Technology (MT) Program at the University of Utah, Department of Pathology. Following the second year of professional courses, MLT students complete 15 weeks of clinical rotations in the Salt Lake Metropolitan area. MLT students as well as MT students benefit from their shared experiences in combined courses that are taught on the university campus.

Suitability of new chlamydia transport medium for transport of herpes simplex virus.

A new chlamydia transport medium (ChlamydiaPort; Scott Laboratories, Inc., Fiskeville, R.I.) was evaluated for its suitability as a transport medium for herpes simplex virus (HSV). Two laboratory HSV strains (McIntyre and 333) and two clinical isolates (AO218 and AO301) were suspended in ChlamydiaPort, ViraPort (Scott Laboratories), and cell culture medium and maintained at 2 and 22 degrees C. Samples were tested at various time intervals to determine surviving virus. The range of half-lives of the HSV strains held at 2 degrees C in ChlamydiaPort medium was from 3.5 to 10 days, while virus stability was greater in ViraPort and less in cell culture medium. These HSV strains held at 22 degrees C in ChlamydiaPort had half-lives from 1.5 to 6 days, which were significantly greater than the half-lives of the viruses held in either tissue culture medium or ViraPort. Clinical specimens were tested for virus by using the Selecticult-HSV (Scott Laboratories) system to determine the performance of the transport medium under field conditions. Clinical specimens maintained up to 5 days at ambient temperatures in ChlamydiaPort medium appeared suitable for diagnostic testing without detectable loss of positive specimens. In addition, there was a significant decrease in the average time required for diagnosis when compared with a standard transport system, Virocult (Microdiagnostics, Cleveland, Ohio). These results show that HSV infections can be successfully diagnosed in distant virology laboratories by shipping specimens in ChlamydiaPort transport medium at ambient temperatures.

Production and reactivity of immune sera specific for HADEN virus polypeptide antigens.

Antisera were prepared against the three structural polypeptides of HADEN virus dissociated with sodium dodecyl sulfate. These immunological reagents were used in immunofluorescence tests to study the kinetics and location of polypeptide antigen appearance in infected cells. These sera did not neutralize virus infectivity, did not cross-react with adenovirus-associated virus-infected cells, and reacted in complement fixation tests with sodium dodecyl sulfate-dissociated virus, but not with complete virus antigen. The polypeptide antigens were heat labile, and all appeared in infected cells at least 2 h prior to whole-virus antigen.
