Cotton and Surgical Face Masks in Community Settings: Bacterial Contamination and Face Mask Hygiene

Frontiers in Medicine, 2021
During the current COVID-19 pandemic, the use of face masks has become increasingly recommended and even mandatory in community settings. To evaluate the risk of bacterial cross-contamination, this study analyzed the bacterial bioburden of disposable ...

Estimating Bacterial Load in FCFM Imaging [PDF]

, 2017
We address the task of detecting bacteria and estimating bacterial load in the human distal lung with fibered confocal fluorescence microscopy (FCFM) and a targeted smartprobe. Bacteria appear as bright dots in the image when exposed to a smartprobe, but they are often diffcult to detect due to the presence of background auto fluorescence inherent to ...

Study on association of nuclear factor kappa B gene polymorphism with bacterial load in pulmonary tuberculosis

The Journal of Association of Chest Physicians, 2023
Objectives: Pulmonary tuberculosis (PTB) is a leading infectious disease and a major public health concern. Out of susceptible genes, nuclear factor kappa B (NF-κB) gene influences inflammation and hence the progression of the disease.

Pathological changes of highly pathogenic Bacillus cereus on Pelodiscus sinensis

Veterinary Quarterly, 2023
An outbreak of a disease with a high mortality rate occurred in a Chinese Softshell Turtle (Pelodiscus sinensis) farm in Hubei Province. This study isolated a highly pathogenic Bacillus cereus strain (Y271) from diseased P. sinensis. Y271 has β hemolysis,

Bacterial load and defective monocyte-derived macrophage bacterial phagocytosis in biomass smoke-related COPD [PDF]

European Respiratory Journal, 2018
Lower airway colonisation with species of potentially pathogenic bacteria (PPB) is associated with defective bacterial phagocytosis, in monocyte-derived macrophages (MDMs) and alveolar macrophages, from tobacco smoke-associated chronic obstructive pulmonary disease (S-COPD) subjects.

Nasopharyngeal Pneumococcal Density and Evolution of Acute Respiratory Illnesses in Young Children, Peru, 2009–2011

Emerging Infectious Diseases, 2016
We examined nasopharyngeal pneumococcal colonization density patterns surrounding acute respiratory illnesses (ARI) in young children in Peru. Pneumococcal densities were dynamic, gradually increasing leading up to an ARI, peaking during the ARI, and ...
