| transmission of ehrlichia canis to dogs by ticks (rhipicephalus sanguineus). | two strains of rhipicephalus sanguineus acquired ehrlichia canis by feeding as either larvae or nymphs on acutely infected dogs and, in subsequent instars, transmitted the agent to normal dogs. three strains of r sanguineus transmitted e canis as adults after their larval and nymphal stages fed on infected dogs. more than 400 adult female ticks were fed on infected dogs as larvae or nymphs or both, but none transmitted e canis transovarially. | 1975 | 1147359 |
| the control of ticks, fleas and lice on dogs by means of a sendran--impregnated collar. | plastic collars impregnated with 9,4% sendran effectively controlled adult rhipicephalus sanguineus for a period of 49 days and immature ticks for a period possibly in excess of 70 days when fitted to four dogs. four uncollared dogs served as controls. although flea burdens were extremely low the collars were apparently effective for a period in excess of 70 days. a medicated collar killed all the ticks, fleas and lice on a severely parasited dog within a period of 48 hours. | 1976 | 1263190 |
| a survey of ticks on farm animals in libya. | thirteen species of ixodid ticks and two species of argasid ticks were collected during a three-year survey of 58 farms in libya. these included boophilus annulatus, b. microplus, b. decoloratus, seven species of hyalomma, rhipicephalus sanguineus, rh. evertsi, rh. bursa, argas persicus and ornithodoros foleyi. this is the first recording of b. microplus, b. decoloratus and rh. bursa in libya. of 20,391 animals examined by random sampling, 2020 (9.6%) had ticks; particularly common were hy. drom ... | 1992 | 1288437 |
| identification of spotted fever group rickettsiae using polymerase chain reaction and restriction-endonuclease length polymorphism analysis. | in order to facilitate the isolation and identification of spotted fever group (sfg) rickettsiae from their tick vectors, we used the centrifugation shell vial technique or traditional isolation procedures and genotypic identification using the restriction fragment length polymorphism analysis of polymerase chain amplified fragments. the presence of rickettsia conorii both in rhipicephalus sanguineus ticks collected in southern france, and in rhipicephalus simus and haemaphysalis leachi from zim ... | 1992 | 1350164 |
| evaluation of devices for removing attached rhipicephalus sanguineus (acari: ixodidae). | three types of forceps and a commercially available device, the tick solution, were used to remove adult brown dog ticks, rhipicephalus sanguineus (latreille), from dogs. the tick solution proved least effective at removing ticks, requiring significantly more removal attempts compared with forcep-removal methods. medium-tipped angled forceps provided the best overall performance. other advantages and disadvantages of the devices are discussed. | 1992 | 1404275 |
| tick (acari: ixodidae) attachment cement and salivary gland cells contain similar immunoreactive polypeptides. | a specific antiserum (12c) raised to a 90-kda immunogenic component of salivary glands of the tick rhipicephalus appendiculatus recognized similar 90-kda polypeptides from salivary glands of the american dog tick, dermacentor variabilis, and the lone star tick, amblyomma americanum, as well as 70-kda polypeptides in the cement of d. variabilis, a. americanum, and r. sanguineus (brown dog tick). the reduction in size of the polypeptide for these ticks suggests that it is modified in some way duri ... | 1992 | 1495047 |
| spotted fever rickettsiae in ticks from the northern sinai governate, egypt. | a field study was initiated in 1988 to investigate whether spotted fever group rickettsiae occur in geographic areas in egypt that are adjacent to an area in the southern israeli negev that has a defined focus of spotted fever disease. ticks were collected from dogs, sheep, and camels at four study sites in the northern sinai. tick hemolymph was processed for rickettsial detection by staining with fluorescein isothiocyanate-conjugated antibody to rickettsia rickettsii. of the 442 hemolymphs exam ... | 1992 | 1599048 |
