Microbial burden on environmental surfaces in long-term care facilities: a quantitative analysis.

Background: We conducted a quantitative analysis of the microbial burden and prevalence of epidemiologically important pathogens (EIP) found on long-term care facilities (LTCF) environmental surfaces.

Methods: Microbiological samples were collected using Rodac plates (25cm2/plate) from resident rooms and common areas in five LTCFs. EIP were defined as MRSA, VRE, C.

Evaluation of antibiotic-resistant bacteria in home kitchens and bathrooms: Is there a link between home disinfectant use and antibiotic resistance?

Objective: To determine the relationship between home disinfectant use and the prevalence of antibiotic resistance among environmental isolates of human pathogens.

Methods: Bacteria were cultured from 5 kitchen and 5 bathroom sites using quantitative methods. Antibiotic susceptibility was determined by standard methods.

Inactivation of and by ultraviolet-C.

We evaluated the ability of an ultraviolet-C (UV-C) room decontamination device to kill and . With an organic challenge (fetal calf serum), the UV-C device demonstrated the following log reductions for of 4.57 and for of 5.
