Tail Docking

Amputation of the tail of a lamb.

Tap Water

Water coming out of the sink faucet; contains chlorine, which is bad for the fish and will kill them. If used to wash equipment, make sure equipment is dry before using it or rinse it with system water.

Task Codes

Codes used by lab personnel to indicate the type of care provided.

  • F: Feed provided (restricted or topped off)
  • W: Water bottle topped off
  • CW: Changed water bottle
  • CC: Cage change performed
  • S: New cage started

Technician Time Charges

  • Supplies: An amount or quantity of a commodity that is needed outside the normal per-diem fee schedule. For example: additional cages, water bottles when placed long-term on ventilated racks, and non-standard lab requested Personal Protective Equipment (PPE). Note: the time spent and/or service provided must also be charged to the lab monthly.
     
  • Services: To provide time and assistance with a specific job/ task above and beyond standard husbandry duties. For example: euthanasia, amount of time spent changing diabetic animal cages, etc. Technician time may also refer to additional supplies used and provided beyond the normal standard operating procedures.
     
  • Technical Services: Laboratory requested contracted services to be provided by the ULAM Technical Service Team. For example: checking plugs, tagging, tailing, bleeds, injections, measure tumors, etc. Note: the time it takes to provide the service will be billed in 15-minute increments unless management approves otherwise.
     
  • Overtime: Will be charged to time spent providing additional services on weekends, holidays, or after regular working hours (6:00 AM - 4:15 PM). Overtime charges will be a multiplication of the total time on weekends/holidays/after hours by 1.5 (ULAM Business Office personnel will perform this calculation).

Tecniplast Recirculating Tank System

Standard recirculating housing for frogs and fish in which water recirculates throughout the rack.

Temperature Set Point

Room temperature desired to be maintained for each species according to the room temperature table (see Appendix A in the Animal Room Environmental Monitoring SOP).

Temperature Tape

Sticker that is placed on equipment processed through cage wash machines that indicates highest temperature equipment reached up to 180°F.

Teratogen

An agent capable of causing developmental abnormalities.

Test-and-Cull

This method of eradication is an option for most viral outbreaks in SPF barrier rodent rooms (i.e. rodents housed in microisolator cages). Because microisolator cages are individual biologic units, if appropriate technique is used, there should be minimal risk of viral spread from cage to cage. Eradication is directed at testing one or all mice in each cage and euthanizing any positive cages. This definition may change in unique circumstances.

The Elements Of Fire

The fire tetrahedron can be applied to fires associated with animal use procedures.

Thermo-Hygrometer

Device capable of reading max/current/min temperature as well as relative humidity.

Topical (epicutaneous)

The application of substances directly to the skin for topical effect.

Toxin

An antigenic poison or venom of plant or animal origin, especially one produced by or derived from microorganisms and causing disease when present at low concentration in the body.

Toxoid

A vaccine administered for long-term protection against a bacterial toxin.

Transdermal (percutaneous)

The application of substances directly to the skin for systemic effect.

Transport Cage

Complete cage set up; including cage bottom, feeder, and micro-isolation top.

Treatment (Tx)

This indicates this animal is being treated for tumor ulceration or a condition secondary to its tumor burden after veterinary consultation or as outlined in the animal use protocol (ex. diet gel will be provided when body condition drops below a 3 out of 5).

Document any laboratory approved ULAM veterinary treatment recommendations (i.e. dietary supplementation, SQ fluids, topical triple antibiotic ointment, etc) on the Tumor Monitoring Form - Cage Card Size (see Appendix A of the Guidelines and SOP on Tumor Monitoring) or on the Tumor Monitoring Form - Notebook Size (see Appendix B of the Guidelines and SOP on Tumor Monitoring) and include the date of treatment, the unique identifier of the cage treated, the treatment itself, and the initials of the person administering the treatment.

Treatment and Observation Sheet

A full-page form used for documenting information for inclusion in the permanent medical record.

Treatment Card

A cage card-sized form for recording rodent treatments as they are completed. This is one option for documenting treatments provided by investigative personnel.

Trio

Alternative breeding strategy in which two adult females and one adult male are co-housed resulting in two litters. One of the adult females must be removed prior to parturition such that only one litter is born in the cage unless breeding records demonstrating problem breeding are submitted as scientific justification for overcrowding and approved by the IACUC. Singly housed pregnant females or stud males should be labeled with a blue tab as described in the Identifying Single Housed Animals SOP.

TST

Technical Service Team. Part of the Unit for Laboratory Animal Medicine (ULAM). E-mail address: ULAM-Techservice@med.umich.edu.

Tuberculin

A sterile liquid containing the growth products of, or specific substances extracted from the tubercule bacillus.

Tuberculosis (TB)

Applied generally to diseases caused by the tuberculous group of bacteria in the genus Mycobacteria.

Tumor Monitoring Exam

A hands-on exam evaluating for each animal for body condition score, hydration, general behavior, mobility and other contributors to the End-Stage Illness Scoring System in addition to any protocol-specific endpoints like tumor size or tumor ulceration.

Tumor Monitoring Records

A record maintained by investigative personnel that includes the dates and observation codes for animals with experimentally induced tumors. Detailed information on tumor monitoring can be found in the Guidelines and SOP on Tumor Monitoring.
