rickettsia typhi in rodents and r. felis in fleas in yucatán as a possible causal agent of undefined febrile cases.rickettsia typhi is the causal agent of murine typhus; a worldwide zoonotic and vector-borne infectious disease, commonly associated with the presence of domestic and wild rodents. human cases of murine typhus in the state of yucatán are frequent. however, there is no evidence of the presence of rickettsia typhi in mammals or vectors in yucatán. the presence of rickettsia in rodents and their ectoparasites was evaluated in a small municipality of yucatán using the conventional polymerase chain r ...025923891
spirochaeta morsus muris, n.sp., the cause of rat-bite fever : second paper.1. since our first report on the discovery of the cause of rat-bite fever, we have been able to prove the existence of the same spirochete in five out of six more cases which have come under our observation. 2. the clinical symptoms of rat-bite fever are inflammation of the bitten parts, paroxysms of fever of the relapsing type, swelling of the lymph glands, and eruption of the skin, all occurring after an incubation period usually of from 10 to 22 days, or longer. 3. our spirochete is present i ...191719868077

experimental rickets in rats : vii. the prevention of rickets by sunlight, by the rays of the mercury vapor lamp, and by the carbon arc lamp.young rats on a diet low in phosphorus can be protected from rickets by irradiations with sunlight for about 15 minutes daily. in the winter months, however, this degree of light was found insufficient. the effective rays of the sun, in the intensities studied, did not penetrate window glass. they manifested some protective value after reflection from a smooth white surface. irradiation of a few minutes with the rays of the mercury vapor lamp suffices to protect rats against rickets. this is tru ...192219868685

geotropic orientation of young rats.the geotropic orientation of rattus rattus (roof rat) obeys the equations previously found applicable for rattus norvegicus. the former is more sensitive, geotiopically, and the numerical values of the constants in the equations for the two forms are found to differ significantly. certain consequences of this difference are pointed out.192719872340

plague in africa from 1935 to 1949; a survey of wild rodents in african territories.the history of plague in africa during the period 1935-49 is reviewed. much of the information derives from a questionnaire sent to all african territories in 1950. the annual incidence of plague in africa declined, particularly from 1946 onwards. in 1949, under 400 cases were reported, as compared with over 6,000 in 1935. by the end of 1949, plague was still active in the belgian congo, kenya and tanganyika, madagascar, and southern africa. no cases were reported from egypt, tunisia, algeria, m ...195313115987

wild-rodent-flea control in rural areas of an enzootic plague region in hawaii; a preliminary investigation of methods.preliminary field tests were carried out to develop methods for controlling fleas on wild rodents in the enzootic plague region of the island of hawaii. among several designs, a metal hood-type ddt bait-box was developed which was simple in design, low in cost, easy to transport to and maintain in the field, protected the insecticide from the elements, and attracted all species of field rats inhabiting a gulch in the hamakua district. these rats-rattus rattus (and its subspecies), r. norvegicus, ...195513260882

epidemiological studies of plague in india: 2. the changing pattern of rodents and fleas in calcutta and other cities.data from early in the twentieth century up to the present day indicate that rattus rattus among rodents and xenopsylla cheopis among fleas are the two most important elements in urban human plague infection in india, r. norvegicus playing a more minor role. the relative numbers of both these species have decreased in recent years in bombay and calcutta, while those of bandicota bengalensis, which is less heavily parasitized by x. cheopis, have risen. this reduction in the numbers of the epidemi ...196020604076

studies on the parasitic helminths of korea: ii. parasites of the rat, rattus norvegicus erxl. in seoul, with the description of capillaria hepatica(bancroft, 1893) travassos, (1915).an investigation of the helminth parasites of house rat r. norvegicus erxl. in seoul has been carried on four years. a total of 325 rat was examined. ten species of helminths were considered, of which 4 species were recored for the first time from korea. the adult worm of capillaria hepatica, the most common parasite of house rats in seoul, was observed experimentally, and provided a more complete description of this worm.196412913610
[the experimental studies on capillaria hepatica]capillaria hepatica is an extremely common parasite of rats. several human cases have also been reported from various parts of the world and recently these aroused the clinical interests. the present study was undertaken to investigate the biological observations of c. hepatica and the changes occurring in blood picture and serum protein in the experimentally infected hosts. the source of c. hepatica obtained from the deposit of non-embryonated eggs encapsulated in the liver of house rats(rattus ...196412913611

double mating: its use to study heritable factors in dental caries.when osborne-mendel female rats (white) were mated with both an osborne-mendel and an nih black rat male during the same breeding period, litters were born which contained both osborne-mendel (white) and crossbred (grey to black) offspring. the osborne-mendel and crossbred animals developed widely different levels of caries activity even though they were exposed to identical environmental conditions during the intrauterine, preweaning, and experimental periods. these findings are indicative of a ...19655827346

a serological survey of rodent plague in taiwan and offshore islands.serological surveys were made on individual sera of small animals trapped on taiwan and offshore islands. the animals were shrews of the species suncus murinus, and rats of the species rattus rattus and r. norvegicus. the tests showed that on makung in the peng-hu islands (pescadores), 66% of the shrews, 30% of the r. rattus and 15% of the r. norvegicus had passive haemagglutination titres with fraction 1 antigens in the range of 1:16 to 1:256, indicative of previous plague infections. these obs ...19685303332
