| the survival of leptospira (spirochaeta) icterohaemorrhagiae in nature; observations concerning microchemical reactions and intermediary hosts. | 1. leptospira icterohaemorrhagiae is unable to grow in the urine, either with or without the addition of suitable culture ingredients, the acidity of the urine being detrimental to the growth. it survives less than 24 hours, unless the urine is neutralized or slightly alkalized, when the period of survival is somewhat longer. if suitable nutrient ingredients are added to the neutralized or slightly alkalized urine, the organism is able to grow for about 10 days, after which multiplication ceases ... | 1918 | 19868229 |
| the distribution of rickettsia in the tissues of insects and arachnids. | in the absence of a satisfactory definition of rickettsia the observations herein recorded were arbitrarily limited to bacterium-like organisms which are intracellular and gram-negative. rickettsia of this type were found in the following species: amblyomma americana, amblyomma hebraeum, boophilus decoloratus, atomus sp., casinaria infesta, chrysopa oculata, ctenocephalus canis, dermacentor variabilis, lepisma saccharina, lucoppia curviseta, margaropus annulatus, margaropus annulatus australis, ... | 1923 | 19868737 |
| cultivation of rickettsia-like microorganisms from the rocky mountain spotted fever tick, dermacentor andersoni. | a systematic study of 74 ticks, the infectivity or non-infectivity of which was determined by biting experiments, inoculation of emulsions, and specific immunity tests, showed the presence in some instances of several types of microorganisms morphologically resembling the inciting microorganism of spotted fever. the most frequently isolated was b. rickettsiformis, n. sp., those less commonly encountered were b. pseudoxerosis, n. sp., and b. equidistans, n. sp. these organisms are non-pathogenic ... | 1926 | 19869142 |
| a filter-passing virus obtained from dermacentor andersoni. | an invisible, filter-passing virus, pathogenic for the guinea pig, and capable of cultivation on special media for at least seven generations, has been isolated from a tick of the species dermacentor andersoni. one of two monkeys (macacus rhesus) inoculated became infected, and in one rabbit the result was negative. the virus has been transmitted from infected guinea pigs to ticks as also in one instance by tick feeding from an infected tick to a guinea pig the presence of the virus in the tick ... | 1926 | 19869167 |
| etiology of oroya fever : v. the experimental transmission of bartonella bacilliformis by ticks (dermacentor andersoni). | experiments are reported in which bartonella bacilliformis was transmitted from infected to normal rhesus monkeys by the bite of the tick, dermacentor andersoni. a long period of feeding, both on the infected animal and on the normal animal subjected to infection, was required in order to secure positive results. the infection transmitted by the ticks was mild, but definite, as shown by the recovery of bartonella bacilliformis from the lymph nodes and blood. | 1926 | 19869219 |

| hereditary transmission of the western type of equine encephalomyelitis virus in the wood tick, dermacentor andersoni stiles. | the western type of equine encephalomyelitis virus can be passed as an hereditary infection in a tick of the family ixodidae, dermacentor andersoni stiles. under experimental conditions, this virus has been carried in this tick for two successive generations, possibly for a third, passing certainly once, and possibly twice, from the female through the eggs to the larvae. the virus-carrying larval, nymphal, and adult stages of this tick, furthermore, are capable of infecting susceptible hosts whe ... | 1941 | 19871094 |

| blood-sucking vectors of encephalitis: experimental transmission of st. louis encephalitis (hubbard strain) to white swiss mice by the american dog tick, dermacentor variabilis say. | (1) the common dog tick, dermacentor variabilis, is capable of being infected with the virus of st. louis encephalitis, hubbard strain, by feeding on inoculated animals and, once infected, can transmit the virus to normal susceptible animals by bite. (2) a female can transmit the infection to her offspring, through all stages of metamorphosis of the 2nd generation into the 3rd generation. (3) ticks infected under laboratory conditions and kept inactive at a temperature of 12.5 degrees c., remain ... | 1944 | 19871380 |
| the experimental transmission of colorado tick fever. | 1. the symptoms, history of tick bite, characteristic fever curve, and white blood cell picture should enable the physician to make a diagnosis of colorado tick fever in nearly every case. 2. the typical white blood cell picture is a depression of the total leucocytes with a shift to the left of the granulocytes. basophilic cytoplasmic bodies appear occasionally in lymphocytes 3 to 4 days after clinical recovery. 3. the disease can be transmitted serially in human beings by parenteral injection ... | 1944 | 19871406 |
