| phylogenetic foundation of spirochetes. | the spirochetes are free-living or host-associated, helical bacteria, some of which are pathogenic to man and animal. comparisons of 16s rrna sequences demonstrate that the spirochetes represent a monophyletic phylum within the bacteria. the spirochetes are presently classified in the class spirochaetes in the order spirochetales and are divided into three major phylogenetic groupings, or families. the first family spirochaetaceae contains species of the genera borrelia, brevinema, cristispira, ... | 2000 | 11075904 |

| characterization of spirochetal isolates from arthropods collected in south moravia, czech republic, using fatty acid methyl esters analysis. | aim of this study was to evaluate cellular fatty acid analysis for characterization of spirochetes. strains were isolated from arthropods collected in south moravia, czech republic. fatty acid methyl esters (fame) profile was determined for five borrelia burgdorferi sensu lato (s.l.) strains isolated from ixodes ricinus ticks, one "spironema culicis" strain recovered from mosquito culex pipiens and seven spirochetal strains (not identified yet) isolated from mosquitoes and blackflies. analysis w ... | 2004 | 15261818 |

| morphological characteristics and nomenclature of leptospira (spirochaeta) icterohaemorrhagiae (inada and ido). | the present study deals with the morphology and systematic position of the causative agent of infectious jaundice. there are several features which are not found in any of the hitherto known genera of spirochaetoidea which led me to give this organism an independent generic name, leptospira, denoting the peculiar minute elementary spirals running throughout the body. the absence of a definite terminal flagellum or any flagella, and the remarkable flexibility of the terminal or caudal portion of ... | 1918 | 19868227 |
| the spirochetal flora of the normal male genitalia. | the varieties of spirochetes enumerated and photomicrographed from the male smegma flora represent practically every form hitherto described by nankivell and sundell and by patterson in the specimens of urine from trench fever cases (figs. 32 and 33). the urethral flora, as studied by stoddard, seem to contain more varieties, but, except those of his more detailed morphological descriptions, every form observed by him is among those found in the smegma. stoddard saw certain forms with hooked end ... | 1918 | 19868233 |
| the spirochetal flora of the normal female genitalia. | the spirochetal flora of normal female genitalia is similar to that of the male and consists of treponema calligyrum, treponema minutum, and spironema refringens. the types are present in varying proportions, but the calligyrum usually predominates, and the refringens is the least frequent. the female genitalia are much richer generally in the number of spirochetes than the male. | 1918 | 19868277 |
| relapse phenomena of spironema recurrentis. | 1. squirrels and chipmunks were found to be susceptible to infection with the spironema recurrentis of north china, but no relapses occurred in normal animals. 2. splenectomy caused an increase in the intensity of the infection and the appearance of one or two relapses. 3. by inoculating splenectomized squirrels with a single human strain of spirochetes, six different strains were produced as a result of relapses. 4. the strains all retained their specific agglutinating characteristics during th ... | 1928 | 19869472 |
| suppression of the first attack with subsequent relapse: an immune phenomenon in experimental relapsing fever. | in five splenectomized squirrels and chipmunks which were reinoculated with a strain of spironema recurrentis which had previously been present in their blood, the first attack was entirely suppressed because the animals were immune to the strain of spirochetes inoculated; but after the interval which usually occurred between attacks, a relapse ensued, in which the strain of spirochetes present in the blood was different from the strain inoculated. | 1928 | 19869522 |
