What's the difference between variola and variolous?
Variola
Definition:
(n.) The smallpox.
Example Sentences:
(1) It is therefore possible to describe both the viruses as being very close to the variola virus.
(2) On the contrary, the vaccination against variola has to be discontinued.
(3) Household aggregation of cases, one possible characteristic of person-to-person transmitted disease, was formally tested in one epidemic of variola minor by using a pair statistic.
(4) Aerosol mixtures of the psittacosis agent, yellow fever virus, and variola virus were assayed by selective immunofluorescence in conjunction with fluorescent cell counting.
(5) The results also indicate that Cercopithecus aethiops are not very susceptible to infection with either variola major or minor.
(6) Of the three agents, variola virus exhibited the lowest biological decay.
(7) Various strains of vaccinia, variola, whitepox, monkeypox and cowpox viruses were examined for their capacity to induce a specific early antigen detectable on the surface of infected cells.
(8) Furthermore, whereas the specific humoral antibody response in the undernourished subjects was partially adequate, the development of specific cellular immunity against vaccinia was remarkably poor, indicating that smallpox vaccination in these subjects might be less effective against variola infection.
(9) This is strong evidence that monkeypox virus is not ancestral to variola virus and strengthens confidence in the long-term success of smallpox eradication.
(10) Some, from Turkmenistan rodents or from white rats caught near Moscow, appeared to be very close to cowpox virus, while others (from Zaire rodents) were identical to variola-like (whitepox) viruses found earlier in monkeys in the same region.
(11) No student with a previous attack of variola showed any clinical manifestation in any school.
(12) Also shown are the numbers of students with variola and of students without variola but with homemates with variola, by grade and school.
(13) The Chimp-9 and 64-7255 strains differed from the variola virus only in their greater pathogenicity for white mice after intracerebral inoculation.
(14) It was established that microfocus assay of the variola virus in HeLa cell cultures on Microtiter plates is a suitable method for titrating the virus in numerous specimens of small volume.
(15) Trend-surface analysis (TSA), a form of polynomial regression used in geology, ecology and geography, was applied to analysis of the spread of an epidemic of variola minor in a small Brazilian city.
(16) In general, the features are indistinguishable from the papulonecrotic stage of smallpox (variola) and from tanapox as recorded in man.
(17) Endonuclease SmaI cleaves exceptionally infrequently and distinguishes variola, monkeypox, vaccinia, cowpox or ectromelia viruses.
(18) Electropherograms of continuous (8%) and gradient (3 to 30%) gels were made of purified vesicular stomatitis virus, variola virus, Rickettsia rickettsii, and alpha and beta chains of hemoglobin in order to demonstrate the resolution of the gradient system.
(19) The isolated strains produced small necrotic haemorrhagic pocks on CAM, grew well at 39.0 degrees C, formed large plaques in Vero cell cultures, showed markedly more virulence for chick embryos and mice than do variola strains, and produced large necrotic haemorrhagic local lesions with generalized illness and florid secondary exanthem when inoculated into rabbit skin.The finding of smallpox-like illness in humans resulting from infection with a poxvirus of lower animal origin serves to emphasize the importance of thorough epidemiological and laboratory evaluation of all suspect smallpox cases occurring in areas where smallpox has been or is about to be eradicated.
(20) An overall description of the epidemic of variola minor (alastrim) affecting Bragança Paulista County (Brazil) in 1956 is given.
Variolous
Definition:
(a.) Of or pertaining to the smallpox; having pits, or sunken impressions, like those of the smallpox; variolar; variolic.
Example Sentences:
(1) With smallpox, the variolation (since 1730) gave first relief, until Sir Edward Jenner discovered in 1798 the highly successful cross-immunity through vaccination.
(2) Smallpox vaccination was known as variolation before the modern practice of vaccination with cowpox (Vaccinia) was demonstrated in 1796.
(3) Man's first attempt to immunize susceptibles against smallpox infection was by variolation, a practice which could be traced back several thousand years.
(4) Variolation is an ancient method of protection against naturally acquired smallpox that was officially proscribed in the early 1950s but was renewed in remote areas when smallpox vaccination activities were interrupted during the three-year famine of 1959-1962, following the "great leap forward" program of 1958.
(5) The last known cases occurred in 1965, and the practice of variolation is now believed to be extinct.
(6) The health authorities responded by capturing the variolators, confiscating their variolation material and equipment, and vaccinating the population.
(7) Fear of smallpox provoked the first important attempts to prevent epidemic disease by a primitive form of immunization called variolation.
(8) All were among persons who had been variolated or were their close contacts.
(9) It is ironic that smallpox became an epidemic pestilence upon the growth of populations, yet it played a major role in preventing population growth until variolation and vaccination became common.
(10) It was found that the variolators in Shanxi Province and Nei Monggol Autonomous Region inoculated persons with the use of powdered smallpox scabs mixed with human milk, and that they obtained fresh supplies of scabs every 6-12 months by variolating relatives and friends.
(11) Smallpox existed in Romania since the 17th century, when both variolation and vaccinia were used for preventing the disease.
(12) Tissot's influence manifested itself also in the early introduction of variolation.
