  1. Weil-Felix test

    Cleanup date July 2009 The Weil Felix test is an agglutination test for the diagnosis of rickettsia l infections . It was first described in 1916. By virtue of its long history and of its simplicity, it has been one of the most widely employed tests for rickettsia on a global scale, despite being superseded in many settings by more sensitive and specific diagnostic tests. History and basis for test The basis of the test is the presence of antigenic cross reactivity between Rickettsia spp. and certain serotypes of non motile Proteus bacterium Proteus spp., a phenomenon first published by Edmund Weil and Arthur Felix in 1916. ref Cruikshank, R. The Weil Felix reaction in typhus fever. 1927. J Hyg Lond 27 1 64 69. ref The serum of patients diagnosed with epidemic typhus was found to agglutinate in the presence of bacteria now known as Proteus vulgaris . Ensuing work elucidated that it was in fact the somatic O antigen that cross reacted with anti rickettsial antibodies, and furthermore, that different Proteus O antigens would cross react with different species of Rickettsia . Typhus group rickettsiae Rickettsia prowazekii , Rickettsia typhi R. typhi react with P. vulgaris OX19, and scrub typhus Orientia tsutsugamushi reacts with Proteus mirabilis P. mirabilis OXK. The spotted fever group rickettsiae Rickettsia rickettsii R. rickettsii , Rickettsia africae R. africae , Rickettsia japonica R. japonica , etc. react with P. vulgaris OX2 and OX19, to varying degrees, depending on the species. ref Walker, DH and DH Bouyer.

    File Transovarian and Transstadial Transmission.jpg thumb 250px Transovarial and transstadial transmission of the Ixodes tick Transovarial or transovarian transmission occurs in certain arthropod Vector epidemiology vector s as they transmit disease causing bacteria from parent arthropod to offspring arthropod. For instance, Rickettsia rickettsii , carried within tick s, is passed on from parent to offspring tick by transovarial transmission. In contrast, Rickettsia prowazekii is not passed on by transovarian transmission because it kills the vector that carries it human louse . This is the mechanism by which many Rickettsiae are maintained in their arthropod hosts through generations.which occurs also in aedes mosquito vector of the yellow fever virus and in Phlebotominae phlebotomine sandflies that transmit pappataci fever ref name Tesh1984 Cite book last Tesh first R.B. year 1984 chapter Transovarial transmission of arboviruses in their invertebrate vectors title Current topics in vector research editor K.F.

Richard Dawkins in The Extended Phenotype page 222 1999 edition notes that bacterial endosymbionts of insects which are transmitted transovarially share an interest in the success of their host s gametes.....as well as the survival of their host s body. In this case, the interest of the host genes and parasite genes might not be quite identical, but they would..... be very much closer than the case of fluke and snail. where host and parasite have different means of propagation into the next generation, and therefore more divergent interests.
