Publication number: 20240085285Abstract: Methods for preparing a biological sample for testing by Maldi where such methods are selected based on sample parameters. Maldi scores are obtained for a range of sample parameters (e.g. McFarland, dispense volume and number of dispenses). From the data, sample preparation parameters can be selected for a biological sample being prepared for Maldi testing. One sample preparation strategy uses multiple dispenses of sample with an intervening drying step, which yields more accurate Maldi scores, particularly for samples at the low range of McFarland values (e.g. below about 2).Type: ApplicationFiled: August 21, 2023Publication date: March 14, 2024Applicant: BECTON, DICKINSON AND COMPANYInventors: Timothy Wiles, John D.

Publication number: 20220170065Abstract: Rapid methods that identify sepsis-causing bacteria or yeast aid the physician in critical therapeutic decision-making, thus decreasing patient mortality rates. The methods described herein employ plating microorganisms directly on to a MALDI-MS plate, adding concentrated formic acid, and identifying the microorganism by mass spectrometry. Optionally, an organic solvent may be combined with the formic acid, or added to the sample before or after the concentrated formic acid is added thereto. The methods enable direct extraction of proteins from microorganisms without the need for liquid protein extraction methods and yields positive identification results for gram-positive bacteria, gram-negative bacteria and yeast in minutes.Type: ApplicationFiled: November 8, 2021Publication date: June 2, 2022Applicant: BECTON DICKINSON AND COMPANYInventors: Liping Feng, William B. Brasso, Susan M. Kircher, Vanda White, Song Shi, Xiao Mo, Tuan-Linh Ngoc Nguyen, Adrien P. Malick, Jon E. Salomon, John D. Mantlo

Patent number: 11291986Abstract: The present disclosure describes pipette tips having an absorbent material (e.g., a flocking material) anchored to a distal end of the pipette tip and related methods of use. In some embodiments, the flocked pipette tips can be used in an automated process and/or system, wherein the contact between the pipette tips and either a sample or a culture medium can be automatically sensed for accurate sample collection and/or dispense. In some embodiments, automatic detection of the liquid interface may be accomplished by detecting a threshold change in capacitance when the pipette tip contacts the sample liquid interface (e.g., for sample collection) or the agar interface (e.g., for sample release). In some embodiments, the automated process and/or system may utilize one or more predetermined, fixed heights for collecting samples and/or depositing samples.Type: GrantFiled: February 23, 2018Date of Patent: April 5, 2022Assignee: BECTON, DICKINSON AND COMPANYInventors: John D. Mantlo, Tong Zhou

Patent number: 11225681Abstract: Various embodiments disclosed herein provide for reagents and methods for rapidly isolating viable microbial cells, including S. pneumoniae, from positive blood culture samples. The resulting microbial pellet can be used for both identification and growth-based methods such as antimicrobial susceptibility testing. The buffers described herein may contain a base solution, non-ionic detergents, thiols, and optionally, ammonium chloride. The disclosed methods provide a process for rapidly isolating and concentrating viable microorganism(s) from PBC samples using only one sample preparation tube and centrifugation while removing cellular debris from the mammalian blood cells that may interfere with identification methods.Type: GrantFiled: November 7, 2019Date of Patent: January 18, 2022Assignee: BECTON, DICKINSON AND COMPANYInventors: Susan M. Kircher, Vanda White, William B. Brasso, Dyan Luper, James Y. Zhou, Julie L. Rosales, Jeffery H. Bruton, John D. Mantlo, Adrien P. Malick, Donald R. Callihan, Ben Turng, Liping Feng, Curtis M.
