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.	1927	19872340

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 ...	1922	19868685

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 ...	1917	19868077
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 ...	0	25923891
