Nontuberculous mycobacteria (NTM) are ubiquitous, environmental bacteria that can cause chronic lung disease. Persons with cystic fibrosis (pwCF) at high risk for NTM. Approximately 1 in 5 pwCF the United States (U.S.) is affected by pathogenic NTM species, and incidence rates of have been increasing among as well general population. Prevalence pulmonary infections (PI) varies widely across because geographic variation exposures. This study will present updated region-level (CF) population...

Background Nontuberculous mycobacteria (NTM) are environmental bacteria which may cause chronic lung disease. The prevalence of NTM pulmonary infection and disease has been increasing in the United States globally. predominant clinically relevant species Mycobacterium avium complex (MAC) abscessus . With development rapid identification methods for (e.g. PCR probes), more testing is being conducted through commercial labs, such as Laboratory Corporation America (Labcorp), provides...

The National Institute of Allergy and Infectious Diseases organized a symposium in June 2022, to facilitate discussion the environmental risks for nontuberculous mycobacteria exposure disease. expert researchers presented recent studies identified numerous research gaps. This report summarizes identifies six major areas future related culture-based culture independent laboratory methods, alternate media culturing conditions, frameworks standardized improved sampling strategies, validation...

Rationale: Nontuberculous mycobacteria (NTM) are ubiquitous environmental bacteria, and some pathogenic species cause lung disease. Environmental factors contribute to increased NTM abundance, with higher potential for exposure infection. Objectives: To identify water-quality constituents that influence the risk of infection in Oregon. Methods: We conducted a population-based cohort study using patient incidence data from Oregon statewide laboratory collected as part public health...

Hawai'i has the highest prevalence of nontuberculous mycobacterial (NTM) pulmonary disease in United States. Previous studies indicate that certain trace metals surface water increase risk NTM infection.To identify whether influence infection O'ahu, Hawai'i.A population-based ecologic cohort study was conducted using incidence data from patients enrolled at Kaiser Permanente during 2005-2019. We obtained sociodemographic, microbiologic, and geocoded residential for all beneficiaries. To...

Laboratory studies have shown that small concentrations of silver are effective at inhibiting the growth micro‐organisms through disruption important cell structures and processes. The additional ability to incorporate into surfaces has increased usage in medical field expanded its use consumer market. To understand impact silver‐containing antimicrobial use, it is determine whether silver‐based goods reducing bacterial populations. Our study examined antibacterial effectiveness Agion...

Nontuberculous mycobacteria are ubiquitous environmental bacteria that frequently cause disease in persons with cystic fibrosis (pwCF). The risks for NTM infection vary geographically. Detection of high-risk areas is important focusing prevention efforts. In this study, we apply five cluster detection methods to identify counties high risk. Four clusters were detected by at least three the methods, including twenty-five states. geographic area and number each depended upon method used....

Recent approaches to TB control have focused on identifying and treating active cases halt further transmission. Patients with symptoms often delay seek care, get appropriate diagnosis, initiate effective treatment. These delays are partly influenced by whom the patients contact within their community network. We aimed evaluate drivers of diagnostic in an urban setting Uganda.

The prevalence of nontuberculous mycobacterial (NTM) pulmonary disease varies geographically in the United States. Previous studies indicate that presence certain water-quality constituents source water increases NTM infection risk.To identify influence risk persons with cystic fibrosis States.We conducted a population-based case-control study using incidence data collected from Cystic Fibrosis Foundation Patient Registry during 2010-2019. We linked patient zip code to county and associated...
