| CPAP | continuous positive airway pressure |
|---|---|

| CPTN | culture-positive toxin-negative |
| reticuloendotheliosis viruses | A subgenus of retroviruses type b, mammalian comprising a few isolates from birds, with no known corresponding endogenous relatives. (12 Dec 1998) |
|---|---|
| C group viruses | A serologic group of the genus Bunyavirus (formerly called group C arboviruses), composed of 12 species including Caraparu, Murutucu, and Oriboca virus. (05 Mar 2000) |
| phlebotomus fever viruses | An unclassified serologic group of arboviruses morphologically like Bunyavirus but antigenically unrelated, transmitted by Phlebotomus papatasi (sandfly) and causing phlebotomus fever; there are 20 strains, including Icoarachi and Itaporanga. Synonym: pappataci fever viruses, sandfly fever viruses. (05 Mar 2000) |
| mink cell focus-inducing viruses | Murine leukaemia viruses discovered in 1976 by hartley, wolford, old, and rowe and so named because the viruses originally isolated had the capacity to transform cell foci in mink cell cultures. Mcf viruses are generated in a multi-step process by recombination with other viral types including akr, friend, moloney, and rauscher. (12 Dec 1998) |
| mosaic viruses | Viruses which produce a mottled appearance of the leaves of plants. (12 Dec 1998) |
| plant viruses | Viruses parasitic on plants higher than bacteria. (12 Dec 1998) |
| mouse leukaemia viruses | Retroviruses of the murine leukaemia-sarcoma complex that produce leukaemia and sometimes lymphosarcomas in mice, including the Abelron, Gross, Moloney, Friend, and Rauscher strains of virus; they have been isolated from inbred mice having high incidence of spontaneous lymphoid leukaemia. (05 Mar 2000) |
| Salisbury common cold viruses | Strains of rhinovirus of historical interest because of early studies that established the viral aetiology of common colds. (05 Mar 2000) |
| helper viruses | Viruses which enable defective viruses to replicate or to form a protein coat by complementing the missing gene function of the defective (satellite) virus. Helper and satellite may be of the same or different genus. (12 Dec 1998) |
| sandfly fever group viruses | A group of viruses in the genus phlebovirus of the family bunyaviridae transmitted by the sandfly, phlebotomus papatasii, and causing a short febrile illness in humans. The sandfly fever sicilian virus, the type species of the phlebovirus genus, is not part of this group. (12 Dec 1998) |
| sandfly fever viruses | An unclassified serologic group of arboviruses morphologically like Bunyavirus but antigenically unrelated, transmitted by Phlebotomus papatasi (sandfly) and causing phlebotomus fever; there are 20 strains, including Icoarachi and Itaporanga. Synonym: pappataci fever viruses, sandfly fever viruses. (05 Mar 2000) |
| sarcoma viruses, avian | Species of avian type c retroviruses (retroviruses type c, avian) producing sarcomata and other tumours in chickens and other fowl and also in pigeons, ducks, and rats. (12 Dec 1998) |
| sarcoma viruses, murine | Species of replication-defective mammalian type c retroviruses (retroviruses type c, mammalian) which are capable of transforming cells, but which replicate and produce tumours only in the presence of murine leukaemia viruses (leukaemia viruses, murine). (12 Dec 1998) |
| sarcoma viruses, simian | Species of mammalian type c retroviruses (retroviruses type c, mammalian) producing tumours in primates. Originally isolated from a fibrosarcoma in a woolly monkey, ssv is a replication-defective v-onc virus which carries the sis oncogene. In order to propagate, ssv requires a replication-competent helper virus, simian sarcoma virus-associated virus (ssav). (12 Dec 1998) |
| satellite viruses | Defective viruses which can multiply only by association with a helper virus which complements the defective gene. Satellite viruses may be associated with certain plant viruses, animal viruses, or bacteriophages. They differ from satellite RNA (RNA, satellite) in that satellite viruses encode their own coat protein. (12 Dec 1998) |
