    Method for detecting coliform organisms

    A method and apparatus are disclosed for determining the concentration of coliform bacteria in a sample. The sample containing the coliform bacteria is cultured in a liquid growth medium. The cultured bacteria produce hydrogen and the hydrogen is vented to a second cell containing a buffer solution in which the hydrogen dissolves. By measuring the potential change in the buffer solution caused by the hydrogen, as a function of time, the initial concentration of bacteria in the sample is determined. Alternatively, the potential change in the buffer solution can be compared with the potential change in the liquid growth medium to verify that the potential change in the liquid growth medium is produced primarily by the hydrogen gas produced by the coliform bacteria

    A system that performs water quality monitoring on-line and in real time much as it would be done in a spacecraft, was developed and demonstrated. The system has the capability to determine conformance to high effluent quality standards and to increase the potential for reclamation and reuse of water

    Rib Osteomyelitis in a Pediatric Patient: Case Report and Review of the Literature

    No full text
    We present a case report and review of the literature of rib osteomyelitis in a pediatric patient presenting to the emergency department (ED) with fever and increased work of breathing. The patient was seen on a return visit to the ED after discharge with presumed viral illness approximately 12 hours prior. On the second ED visit, there was concern for occult bacteremia, and work-up ultimately revealed a subperiosteal abscess with rib osteomyelitis, a rare etiology for fever in the pediatric patient. The patient was treated with antibiotics, had surgical debridement, and fully recovered
