Re: [RFI No. NOT-OD-06-011]

Dear Dr. Snyder:

The American Society for Microbiology (ASM) is responding to the National Institutes of Health (NIH) request for information in seeking to identify new scientific information that might warrant the NIH issuing a contract for a new or updated edition of the Guide for the Care and Use of Laboratory Animals (The Guide) (RFI No. NOT-OD-06-011). The following comments were developed by the ASM Committee on Agriculture and Food Microbiology (Committee), of the Public and Scientific Affairs Board.

The ASM is the largest single life science society with more than 42,000 members, including scientists in academic, industrial, clinical, and government institutions, working in areas related to basic and applied research, the prevention and treatment of infectious diseases, laboratory and diagnostic medicine, the environment, animal health, and water and food safety. The ASM applauds the NIH’s efforts to assist institutions in caring for and using animals in ways judged to be scientifically, technically, and humanely appropriate.

Comments on the Guide for the Care and Use of Laboratory Animals

After carefully reviewing the publications in this area since the last revision of The Guide in 1996, the Committee detected two separate issues:

  1. The number of publications in all the four areas addressed by The Guide has not increased as would have been expected based on the expansion and increase in the use of laboratory animals over the past 15 years. This is most likely attributed to the cuts in funding for the National Center for Research Resources (NCRR) during the early 1990s (3,4). Progress in the area of Laboratory Animal Medicine and Science will only occur if there are appropriate sources of funding. 
  2. The scope of The Guide is very broad and its recommendations are used as benchmarks by many scientists. Changes in some of the base recommendations such as cage size, frequency of bedding and cage washing, and environmental enrichment may be required due to recent studies published that show certain modifications can improve the lives of laboratory animals (1,2,5,6,7,8,9,10,11,12,13).

The Committee notes that there have been publications that increase the body of knowledge in many areas regarding the four main chapters of The Guide, making it imperative to update the literature cited and the appendixes. Additionally, The Guide should be accessible electronically, which would facilitate the ability of scientists to be well informed and up to date. This would enable NIH to constantly update the reference list and make all of the reference documents electronically accessible in their entirety. The Guide should also be available for download onto PDAs and other types of mobile electronic apparatus.
