AMERICAN SOCIETY OF PARASITOLOGISTS NEWSLETTER

PRESIDENT ADDRESSES SOCIETY
In the tradition of past presidents of the American Society of Parasitologists, my message as President will address recent Society activities. A more personal agenda is also presented, followed by a request for volunteers and suggestions.
Over the past decade, the American Society of Parasitologists has become a more proactive society as is evidenced by the numerous new initiatives implemented by Council. In my opinion, these actions are extremely important as federal research dollars to support the study of human and animal parasites shrink while the challenges of maintaining parasite-free water and food sources as well as controlling parasites in human populations continue to grow. In recognition of the importance of these challenges along with the importance of preserving our ability to use animals in research, ASP Council recently moved to make the Political Advocacy Network (PAN) a standing committee. Members of ASP who serve as PAN contacts are notified of pending federal legislative actions on matters concerning science and asked to contact congressional representatives from their area in an effort to influence decisions that may impact not only on us as parasitologists, but also on scientific research in general. In addition, this fall, I will charge the Public Responsibilities Committee with considering membership for ASP in organizations such as Americans for Medical Progress which actively support efforts to assure that animal research will be allowed to continue with a minimum of regulatory measures. In an effort to educate the public on not only the importance of parasites in today's world and the exciting nature of parasitology as a discipline, but also on how parasites can be used in teaching, a new initiative will be implemented this year by the ASP Education Committee - the ASP Speakers Bureau. Council has committed funds to support volunteer speakers from the membership who are willing to address organizations (large or small) and/or students in classrooms. Finally, the Society's Biodiversity Committee has focused on developing a mission statement for ASP interactions in biodiversity research, developing a comprehensive list of taxonomic expertise within the Society, and a synoptic listing of pertinent programs which support biodiversity research. These data will be made available from the Manter Laboratory at the University of Nebraska. In addition, the Committee will write biodiversity editorials for submission to appropriate journals that address the integrative nature of biodiversity research, phylogenetic reconstruction, biogeography and ecology.
To ensure that we will recruit bright young scientists that will continue to support and enjoy the field of parasitology, ASP Council has made a special effort to create an endowment of $100,000 to be used solely for student travel grants. This endowment will provide support for travel by increasing numbers of students as the endowment grows. By making the ASP Auction an integral part of our annual meeting, the proceeds from which support student travel, and by depositing funds, as available, from other sources as well, it is anticipated that by the year 2000 the endowment will be self-sustaining. Once this goal is reached we can begin to divert resources into new initiatives that will increase student participation in the Society and in parasitology in general. Along this line, Council has acknowledged the importance of recognizing contributions of members and non-members to the field of parasitology and the importance of mentoring young scientists in our discipline. As a result, we have moved from a single annual society award, the H.B. Ward Medal, to four additional awards: The Eminent Parasitologist Award, The Distinguished Service Award, and The Mentorship Award. The latter is the most recent addition and will be initiated this year.
The Society is in good health financially and during the past year the Business Advisory Committee and the Secretary-Treasurer have done an excellent job of assessing and reorganizing investments so that maximum interest is realized. However, we need to expand Society supported activities such as symposia, workshops, etc., while maintaining our current financial base. To do this, we need to increase the principal in our endowment funds and develop a system that will allow for more accurate projection of anticipated expenses. To accomplish these goals, Council approved an Endowment Fund Drive which will be initiated this year while the Business Advisory Committee is developing a budget projection plan for the Society.
My personal agenda includes making the Society more "user friendly" for the membership. As an organization, we can be proactive and financially healthy, but if we are not serving the constituency, the Society will not continue to grow in number of members nor expand in disciplinary diversity. As one member of the 1994-1995 Priorities Committee stated, " We need to establish more clearly a list of needs and wants from the membership." Thus, I plan to create an interactive forum for discussion at the 1996 Business Meeting. I urge all of you to attend and participate! I also plan to continue efforts already begun to increase involvement of our colleagues working in the applied areas of parasitology (medical, veterinary and industrial). As was very aptly put by yet another member of last year's Priorities Committee, the lack of participation by this sector is "...particularly distressing in this period of diminished funding possibilities, given that applied research activities provide opportunities for support as well as quality science." Other 1995-1996 Presidential agenda items include completing a handbook for Officers and Committee Chairs that was begun last year, reducing the number of committees (currently we have a total of 35), and reestablishing the rotational service on committees.
In an attempt to make the Business Meeting more interactive and to establish a list of needs and wants from the membership, I request that the membership submit to me items and issues for open discussion at the Business Meeting in Tucson next June. I also extend an invitation to anyone interested in being part of the Public Advocacy Network to contact Larry Roberts (see article on PAN in this Issue), Chair of the PAN, and to those interested in serving as volunteer speakers in your geographic area for the ASP Speakers Bureau to contact Bill Font, Education Committee Chair. Finally, if you are willing to serve on any of the ASP committees, please contact me by October 1 at (915) 747-6894, or by e-mail at dn00%utep@utepvm.utep.edu.
If I am unable to accommodate your request for committee service this year, your name will be passed to the next President, Bob Grieve, who will be making committee assignments in July of 1996.
This is truly an exciting time to be President, and I am very pleased to be able to serve the Society in this capacity.
Lillian F. Mayberry
President of ASP

PLANS FOR 1996 JOINT ANNUAL MEETING OF THE AMERICAN SOCIETY OF PARASITOLOGISTS AND THE SOCIETY OF PROTOZOOLOGISTS BLOSSOM

A joint annual meeting of the American Society of Parasitologists and the Society of Protozoologists will be held June 11-15, 1996 in Tucson, Arizona. To add to an already broad and interesting meeting agenda, the 4th International Workshop on Opportunistic Protozoans will be held in conjunction with the ASP/SP joint meeting. This promises to be among the best, most diverse and most interesting gatherings in which ASP has participated in recent years. Be sure to make your plans early for attending this exciting meeting in beautiful Tucson. ASP PUBLIC ADVOCACY NETWORK REPORTS
A Public Advocacy Network of the American Society of Parasitologists (ASP-PAN) was organized by Dr. J.R. Seed over the past year. The function of ASP-PAN is to act on behalf of our profession when issues of concern to parasitologists become subjects of legislative or regulatory action. Everyone knows that federal, state and local governments enact laws that dramatically affect our personal lives, but acts of governments may also affect our professional lives as parasitologists. Such acts, to name but a few, are changes in research funding for NIH, NSF and NBS, and animal welfare legislation. We heretofore have not had a mechanism by which we as parasitologists could convey our opinions to Members of Congress in an organized way, and we hope that ASP-PAN will meet this need.
As Acting Chair of ASP-PAN in 1994, Dr. Seed contacted a number of ASP members throughout the United States and asked them to serve as regional chairs and co-chairs for ASP-PAN. The regional chairs in turn contacted more members who agreed to contact the Members of Congress from their areas regarding pending legislation that might have an impact on parasitology. At the recent Council meeting in Pittsburgh, Dr. Seed recommended and Council appointed Dr. Larry S. Roberts Chair of ASP-PAN for a three-year term and named him as ASP representative to the Federation of Societies of Parasitology (FSP).
Operation of the ASP-PAN is coordinated with the Legislative Task Force of the American Society of Tropical Medicine and Hygiene and with other parasitology societies in the U.S. through FSP. In its first year of operation, ASP-PAN has had some notable successes. Cooperating with the Task Force of ASTMH and other biological scientists, we avoided a catastrophic cut in the NIH budget and a shut down of the School of Public Health at UCLA. Another success was resolution of a regulation proposed by the U.S. Fish and Wildlife Service on importing and exporting scientific specimens. The proposed USFWS regulation would have increased cost, imposed onerous paperwork, and increased delays in shipment of study specimens.
The ASP-PAN needs more members to increase its effectiveness. The day has passed when we can sit idly by and hope for the best while things get worse. We can make a difference. If you would be willing to phone, fax or write your congressional representatives on bills important to parasitology, we welcome your help. You would be asked to write or call a few times a year. Contact: Dr. Larry Roberts or one of the regional chairs: Janine Caira, Eugene Foor (Northeast Co-Chairs); Ray Kuhn (Southeast Chair); John Oaks, Bert Stromberg (North Central Co-Chairs); Lillian Mayberry, Jane Starling (South Central Co-Chairs); Don Wassom (West [Mountain] Co-Chair); Mike Moser (West [Northwest] Co-Chair); Austin MacInnis (West [Southwest] Co-Chair).

PIONEER PAPERS
Stoll, N.R. 1929. American Journal of Hygiene 10: 334-418 and Stewart, D.F. 1955. Nature 176: 1273-1274.

One of the most fascinating manifestations of the immune response by the host to nematode infections is the self-cure reaction. This phenomenon was first demonstrated by Stoll (1929) who reported that sheep, after undergoing an initial infection, developed a resistance to reinfection by Haemonchus contortus. His study revealed the occurrence of a self-cure process on the part of the host, evidently through elimination of resident parasites. Moreover, animals which had undergone a self-cure were protected against reinfection. The question was raised that certain special conditions associated with the experiment might have caused this effect. Stoll concluded that the most likely possibility was that there occurred in nematode infections of the type of H. contortus the development of a resistance, independent of age resistance which acted to protect the host and might have the same mechanistic basis as that seen typically with bacterial infections. This was indeed a very important finding for parasitic nematode immunology as it presented the first good evidence that immunity to nematode infections could serve in a protective role. It also raised some important implications for better understanding the epidemiology of these infections. Nowadays we take it for granted that a host will develop a protective response to the presence of a worm species, but in 1929 there was little support for this idea. Taliaferro (1929) in his "Immunology of Parasitic Infections" was able to cover the subject of "Acquired Immunity in Infections with Metazoan Parasites" in just 2 pages of a 400+ page book.
Subsequently, Stewart (1953, 1955) reported on studies of the immunologic mechanism of this phenomenon. In these studies, it was shown that the reaction in the host was accompanied by a release of histamine into the blood and a brief rise in circulating antibodies. The rise in blood histamine was observed when sheep infected with either H. contortus or Trichostrongylus colubriformis were given H. contortus infective larvae and subsequently manifested self-cure. It was also shown to occur when self-cure took place in sheep infected with T. colubriformis following the administration of T. colubriformis larvae. No increase in blood histamine was detected when T. colubriformis larvae were given to sheep infected with H. contortus and the self-cure reaction did not occur. Administration of antihistamine drugs prevented the fall in fecal egg counts after the administration of larvae but did not interfere with a rise in circulating antibodies. Furthermore there was no evidence that histamine had a detrimental effect on adult worms. Sheep displaying self-cure were hypersensitive to the intradermal injection of a larval antigen. Infected sheep given a dose of larvae and slaughtered on the day in which they exhibited a rise in blood histamine had edematous changes in the mucosa of either the abomasum or small intestine dependent upon the site of infection. Laparotomy examinations of the abomasa of sheep directly exposed to exsheathed infective larvae showed that in sensitized sheep infected with H. contortus, the abomasa underwent increased peristalsis and segmentation within 10 minutes of exposure and within one hour had contracted in diameter and were pale and edematous. The reactions commenced to subside in 1« to 2 hours and the sheep subsequently manifested self-cure. On the other hand, abomasa of worm-free lambs exposed to exsheathed larvae remained flaccid and normal for the entire period of observation. On the basis of these results, Stewart hypothesized that the self-cure reaction was due to an alteration produced in the environment of the worms by an immunologic reaction caused in hypersensitive sheep by the intake of infective larvae. These results served as the stimulus for a host of later studies on the immunologic effects of nematodes in the gut as well as initiating investigations into the possible mechanisms mediating the immunoexpulsion of populations of worms in immunocompetent hosts.
