Maryland’s Department of Health and Mental Hygiene (DHMH) aims to promote and improve the health and safety of all Marylanders through disease prevention, access to care, quality management and community engagement. Public Health Services is a division of Maryland’s DHMH. Recently, the Maryland Public Health Services Laboratory moved into a six-story laboratory facility, designed to ...
After determining optimum conditions for the coagulation, flocculation and sedimentation processes in terms of turbidity reduction, jar tests were performed using the same waters seeded with test viruses. ...
MC‐LR was administered through gavage once every 48 h for 8 wk. Pure water was used as control. Each female rat was mated with an unexposed adult male rat. Motor development, behavioral development and learning ability of pups were detected using surface righting reflex, negative geotaxis and cliff avoidance tests on postnatal day (PND) 7. Open field and Morris ...
Outbreaks of AJS were identified in some of the camps in 2007 and 2008. Moreover, water samples from drinking water sources were screened for human adenoviruses considered as viral indicators and for hepatitis A virus and HEV. ...
A list of disease causing microorganisms is provided in Figure 1 (figure 1).In addition, 30 percent of cases of hospital pneumonias are attributable to Legionella, a contaminant in hospital water systems (Legionella in Hospitals: A Review. The Journal of Hospital Infection, 18, Suppl A, 481-489). Legionella infection is caused by the inhalation of water aerosols ...
The present study sought to determine if integron-mediated streptomycin and sulfisoxazole resistance genes could be transferred from Shiga toxin-producing Escherichia coli (STEC) strains 6-20 (O157:H7) and 7-63 (O111:H8) to the susceptible strain E. coli K-12 MG1655 in bovine feces (pH 5.5, 6.0, or 6.5) and storm water (pH 5, 6, 7, or 8) at 4, 15, and 28°C, which are average ...
Quantitative characterization of this source at high powers is assisted by deconvolving the hydrophone's calibrated frequency response in order to accurately reflect the contribution of harmonics generated by nonlinear propagation in the water testing environment. Results are compared to measurements with a membrane hydrophone at 0.3% duty cycle and to ...
