Mycoplasma pneumoniae respiratory disease symposium: summation and significance.

The symposium on M. pneumoniae respiratory disease has examined the clinical expression of infection in adults and children, the pathophysiologic disturbances which occur, and the laboratory diagnosis by isolation and serology. That these infections are very common has been well documented; however, a variable incidence over periods of several years tends to minimize importance of the disease for many clinicians. While good laboratory diagnostic methods exist, they provide retrospective insight predominantly and are not useful for early diagnosis or therapeutic decision making. Development of rapid diagnostic methods which are sensitive and specific is an important goal for future research. Success would facilitate our understanding and control of M. pneumoniae disease

Location of attachment moiety on Mycoplasma pneumoniae.

Mycoplasma pneumoniae initiates infection in the human host by attachment to respiratory epithelium. The organism attaches by a specialized terminal structure. Monoclonal antibodies to an organism surface protein (P1) inhibited attachment to respiratory epithelium and were localized to the tip structure by a ferritin antibody label. The P1 protein was degraded by trypsin treatment to smaller polypeptides that possessed the same antigenic determinants as the larger P1 protein when reacted with the specific monoclonal antibody, and evidence has been provided for the existence of multiple antigenic determinants on the attachment protein

Non-Parametric Analysis of ENSO Impacts on Yield Distributions: Implications for GRP Contract Design

The paper reports preliminary results of non-parametric analysis of historical and crop model generated peanut yield series in the Southwest Georgia. The results suggest ENSO phase dependent differences in yield distributions that are similar for both the simulated and actual series. The differences are magnified in GRP insurance premiums.Crop Production/Industries,

Runoff Estimates for Small Rural Watersheds and Development of a Sound Design method. Volume II, Recommendations for Preparing Design Manuals and Appendices B, C, D, E, F, G, & H

Frequency analyses of more than 1,000 small watersheds in the United States and Puerto Rico were used to develop the estimation method for design of peak flow for ungaged watersheds. This method, called the Federal highway Administration (FHWA) method, is conceptually similar to the Bureau of Public Roads (BRP) method developed by W. D. Potter. The FHWA method relates the runoff peak to easily determined hydrophysiographic parameters and is intended for use on watersheds smaller than 50 square miles. The concept of risk is incorporated inot the design procedure. The risk is the probability that one or more events will exceed a specific peak flow within the usable lifetime of the drainage structure. The return period of the design flood peak can then be modified according to the risk the designer is willing to take. Another concept dealing with the probable maximum runoff peak derived as a function of watershed area is included. The flow obtained from this relationship is considered to be the upper limit of the design flow that may realistically be expected to ever occur. As such it may be appropriate to use in situations where the consequences of failure are extremely great
