MEMBERSHIP After a “two-week retirement” in 2007, Beebe relocated to the West Coast and assumed the directorship of the County of San Luis Obispo PHL. Staff The laboratory’s 11 employees include Beebe, seven public health microbiologists, one lab technician and two medical billers. Other services of note include parasitology testing, blood lead testing and rabies testing on animals. Revenue The bulk of the laboratory’s $2.2 million annual budget, about $1.2 million (54%), comes from medical or other fees. About $350,000 (16%) comes from grants, and the remainder (30%) from county coffers. Testing The PHL performs about 38,000 tests per year, with the lion’s share looking for sexually transmitted pathogens, such as HIV, chlamydia and gonorrhea. Other high-volume tests are influenza (anywhere from 250 to 1,000 tests/year) and TB, using the QuantiFERON ® -TB Gold Plus assay, GeneXpert amplification test and traditional culture. PublicHealthLabs @APHL On the environmental side, the PHL tests both drinking water and ambient, recreational water from the nearby Pacific Ocean and local lakes and streams. It also supports area shellfish growers by providing the testing needed to assure the quality of shellfish that have undergone depuration—a process in which the animals are flushed with free-flowing, pure water for about 48 hours to remove bacterial contaminants and physical impurities. Successes Wherever possible, the laboratory favors molecular methods. Beebe said, “We’re using whole genome sequencing (WGS) to help us identify everything that’s coming through the door: bacteria, mycobacteria, soon fungi and yeasts, maybe eventually viruses. The newly expanded molecular PCR menu now runs 17 tests, including a respiratory disease panel, gastrointestinal disease panel and discrete tests for everything from measles virus to norovirus to herpes simplex virus Types 1 and 2. The county laboratory uses a California state PCR assay to test for enterovirus, one strain of which, D68, is thought to be a causative agent of acute flaccid myelitis. Now that the laboratory is performing WGS for the principle enteric pathogens, Salmonella and Shiga toxin-producing E. coli, Beebe is considering joining PulseNet, the national foodborne disease surveillance network. Already, the PHL is a member of the Laboratory Response Network for Biological Threat Preparedness (LRN-B), tasked with testing unknown samples for select agents like anthrax and plague. “It’s not high-volume work,” said Beebe, “but there’s a lot of pressure with every test.” Beebe said, “The success story here has been our transformation from a conventional laboratory to a molecular laboratory, while still maintaining conventional techniques.” One example of this transformation is the PHL’s use of molecular amplification testing for measles and mumps—a test unavailable in local private sector labs. The PHL’s ability to produce high-quality, vaccine- preventable disease results within three to four hours of specimen receipt prompted praise from the county health officer Penny Borenstein, MD, who refers to Beebe’s shop as “that gem of a lab.” Other successes include onboarding whole genome sequencing with help from Colorado bioinformatician Logan Fink—”a tremendous accomplishment for us”— and detecting a “swine flu” influenza A (H1N2) outbreak at the county’s Midstate Fair in 2018.

Currently, the PHL conducts one-way electronic laboratory reporting to both the state department of health and CDC, conducts bi-directional electronic test ordering and results reporting (ETOR) with a few major customers, and participates in the local health information exchange. Beebe is currently trying to establish bi-directional ETOR with two local hospitals, but, he said, “to get to the hospital decision-makers is probably the biggest challenge I’ve faced here.” Goal • “To keep changing with the times.” For example, the PHL was recently awarded the contract to screen county jail inmates for HIV and hepatitis C virus. “We haven’t done hep C antibody testing for probably 15 years, so now we have to bring it up again. We have to be flexible and quick enough to be prepared for whatever comes our way.... We’ve written that story again and again—figuring out how to meet public health needs without a lot of resources. The future looks about like that.” n Fall 2019 LAB MATTERS 39
