MT Public Health Laboratory Guidance Documents

Antimicrobial Resistance

Antimicrobial resistance is a growing threat to effective treatment of infection. The Montana Public Health Laboratory provides the following information to assist providers, pharmacies, and laboratories in their efforts to manage antibiotic use.

Guidance Document for Implementation of Antimicrobial Resistance Testing at MTPHL

CDC’s Epidemiology and Laboratory Capacity Cooperative agreement (ELC) has requested Public Health Laboratories to collect, confirm, and characterize antimicrobial resistant organisms, including carbapenem-resistant Enterobacteriaceae (CRE), Pseudomonas aeruginosa (CRPA), and Candida spp. (especially C. auris). Isolates will be collected from jurisdictional healthcare facilities using a strategy that allows for estimating the burden of antimicrobial resistance within the population served by the Public Health Laboratory. The Public Health Laboratory and state Epidemiologists will collaborate with the state HAI/AR prevention programs and with the Antimicrobial Resistance Laboratory Network regional laboratories (ARLN). This Guidance document will identify expectations for testing, submitting, and reporting. Download the complete guidance document.

COVID Surveillance

The CDC tracks emerging COVID variants through genomic surveillance. Genomic surveillance identifies circulating variants to rapidly inform public health response efforts. Testing, treatment, and vaccination programs can be improved based on regularly updated surveillance of variants, including updating future vaccines if needed. Detection of variants that are more transmissible or cause more severe disease support outbreak preparedness, prevention efforts, and strengthens public health response.

The Montana Public Health Lab is one of the many labs that contribute data to this surveillance program. Sequencing conducted by our lab can help provide a better understanding of local epidemiology and transmission, and these data can help investigate clusters of disease in various settings. Our goal is to receive samples representing all areas of Montana, but we need your help! We are requesting COVID-positive samples be sent to the PHL for “SARS-CoV-2 Variant Surveillance.” 

2024-2025 Influenza Surveillance

Appropriate treatment of patients with respiratory illness depends on accurate and timely diagnosis. Early diagnosis of influenza can reduce the inappropriate use of antibiotics and provide the option of using antiviral therapy.

Surveillance for the 2024-2025 influenza season officially begins on Sunday, September 29th, 2024. Receiving positive influenza specimens to Montana Public Health Lab (MTPHL) for surveillance testing is important in determining the circulating strains and prevalence. MTPHL also shares these specimens with the Centers for Disease Control for further characterization and testing for antiviral resistance.

Please refer to this guidance document for important information.

 Norovirus Surveillance

Montana Department of Health and Human Services (DPHHS) needs your help this season to improve our outbreak surveillance regarding Norovirus in Montana. Gastroenteritis outbreaks or any outbreaks that occur in congregate settings such as schools, nursing homes and child cares are reportable and provide a glimpse inside infectious diseases in Montana. DPHHS is asking our partners to do their part to improve our understanding of norovirus in Montana. 

Letter to laboratories regarding submission of specimens for Norovirus surveillance and outbreak investigation.
