  • Patent number: 6277562
    Abstract: A method of determining the presence of a paraffinophilic organism in a body specimen involves introducing portions of the body specimen into a plurality of receptacles (50-57) which contain a sterile broth and antibiotics. Subsequently, one paraffin coated slide (18) is introduced into each receptacle. After observing organism growth on the paraffin coated slides, at least one slide is subjected to an alcohol-acid fastness test to determine whether the organism is an alcohol-acid fast, an acid-fast organism or a non-acid-fast/non-alcohol-acid fast organism. If it is determined that an alcohol-acid fast organism is present on the first slide, a tellurite reduction assay is performed on a second slide to determine the possibility of a presence of paraffinophilic organism on the second slide.

  • Patent number: 5989902
    Abstract: A method for determining a sensitivity of a nonparaffinophilic hydrophobic microorganism to an antimicrobial agent. The method includes providing at least one receptacle containing an aqueous broth including a carbon source and introducing the nonparaffinophilic hydrophobic microorganism into the receptacle. The method further includes placing into the receptacle (i) a slide coated with a hydrophobic material and (ii) a predetermined quantity of the antimicrobial agent to be tested. By observing the nonparaffinophilic hydrophobic microorganism growth or lack thereof on the slide, it can be determined whether the predetermined quantity of the antimicrobial agent is effective in inhibiting growth of the nonparaffinophilic hydrophobic microorganism on the slide. An associated apparatus is also disclosed.

  • Patent number: 5981210
    Abstract: The method of the invention involves providing a first receptacle and a second receptacle. The first receptacle contains a sterile aqueous broth and the second receptacle contains an aqueous broth including a carbon source. The method then includes placing into the first receptacle a first support surface having a paraffin wax coating thereon and placing into the second receptacle a second support surface having a hydrophobic material coating thereon. A body specimen, such as sputum, is then introduced into each of the first and second receptacles. The presence of a nonparaffinophilic hydrophobic microorganism in the body specimen is determined by observing (i) a lack of microorganism growth on the paraffin coated material of the first support surface and (ii) a presence of microorganism growth on the hydrophobic material coating of the second support surface. The presence of the nonparaffinophilic hydrophobic microorganism can be further confirmed by performing a DNA extraction.

  • Patent number: 5726030
    Abstract: A method of automatically testing the sensitivity of a paraffinophilic microorganism to different antimicrobial agents and concentrations thereof includes a plurality of receptacles each containing an amount of liquid medium, an antimicrobial agent to be tested and the microorganism to be tested. A paraffin containing slide is placed in each receptacle after which incubation is effected. A light scatter sensor is employed to automatically and sequentially monitor the extent of microorganism growth on the slides and the growth on each slide is employed to determine which antimicrobial agent and which concentration is effective to resist growth of the paraffinophilic microorganism. The slides are moved sequentially in operative relationship with the light scatter sensor while resisting rotational movement of the slides. Positive and negative control slides are preferably employed as is a computer in receiving and processing the results of the slide testing. Related apparatus is disclosed.
