Stedman s Medical Dictionary denes a Much is made of problems possessed by sick ani- symptom as any morbid phenomenon or departure mals and people. These problems constitute the basis from the normal in function, appearance, or sensation of the Problem-Oriented Medical Record.

Jeyaprakash Originally published in the journal Experimental and Applied Acarology, Volume 46, Nos 1 4, 329 347. Until molecular tools became available, analysis meth- ods were limited primarily to microscopic observations; some viruses and rickettsia-like organisms were observed infecting diseased M. A new phylogenetic analysis of the Bacteroidetes-Flavobacterium group suggests the unnamed Bacteroidetes in M. However, much of our current information about the role these microorganisms play in the biology of M. We also currently lack any knowledge of the importance of these microorganisms under Weld conditions.

It has been imported and established in Australia and New Zealand in classical biological control programs for the control of mites in apple and peach orchards (Readshaw 1975; Field 1978). Between 1970 and early 1981, at least 470 papers were published on the Phytoseiidae (Tanigoshi 1982) and between 1960 and 1994, more than 420 papers were published on M. The number of chromosomes (3 and 6 in males and females, respectively) and the genetic system of M. Whether this unusual genetic system is inXuenced by the microbial associates (Wolbachia or Cardinium) of M. Whether pesticide-resistant microbial symbionts are associated with these resistances also remains unknown, but many soil microorganisms have been documented to degrade pesticides (Felsot 1989) and microbial gut symbionts of a tephritid have been implicated in the pesticide resistance of its host (Boush and Matsumura 1967). Because mitochondrial organelles are derived from endosymbiotic bacteria, these unusual features will be discussed brieXy below. Diseases of Mites and Ticks 331 Despite this extensive research conducted over the past 60 years, until recently we knew little about the microbial associates of M. We adhere to the term symbiosis in its original deWnition of organisms living together, usu- ally in close association with one another, to the beneWt of at least one organism, with the partners referred to as symbionts. Infection by a particular bacterium may be beneWcial to a host under some circumstances but harmful in other hosts or environ- ments. At one extreme are the ancient symbionts that live in specialized bacteriomes (host organs or cells specialized for housing the symbionts) and are required by their hosts. Facultative symbionts may not reside exclusively in specialized organs and are not strictly necessary for host survival. Pathogenic symbionts may be pathogens at all times, or they may become pathogenic only when the host immune system allows the microorganism to increase in density. The goal of this review is to discuss what we know about the microbial associates (whether they are called endosymbionts, mutualists, pathogens, or have an unknown rela- tionship) of this important predator and provide a brief overview of what can be learned as new methods are applied to understanding these relationships. Then we will discuss what we know (and don t) about the microbial endosymbionts of M. In addition, we will discuss some of the methodological issues restricting our understanding of these relationships. One was located in epithelial cells, and was 47 nm in diameter with a 35-nm electron dense core. Some particles appeared hexagonal in cross section and were some- times associated with paracrystalline structures.
