 paramyxoviruses (from greek para-, beyond, -myxo-, mucus or slime, plus virus, from latin poison, slime) are viruses of the paramyxoviridae family of the mononegavirales order; they are negative-sense single-stranded rna viruses responsible for a number of human and animal diseases. ==classification== paramyxoviridae is split into two sub-families, the paramyxovirinae and pneumovirinae. these sub-families are further diveded into different genera. *subfamily paramyxovirinae **genus aquaparamyxovirus ( type species atlantic salmon paramyxovirus: others include pacific salmon paramyxovirus) **genus avulavirus (type species newcastle disease virus) **genus ferlavirus (fer-de-lance virus): others include anaconda paramyxovirus **genus henipavirus (type species hendravirus; others include nipahvirus) **genus morbillivirus (type species measles virus; others include rinderpest virus, canine distemper virus, phocine distemper virus, ovine rinderpest) **genus respirovirus (type species sendai virus; others include human parainfluenza viruses 1 and 3, as well some of the viruses of the common cold) **genus rubulavirus (type species mumps virus; others include achimota virus 1 and 2, human parainfluenza viruses 2 and 4, simian parainfluenza virus 5, menangle virus, tioman virus, tuhokovirus 1, 2 and 3) **genus tpmv-like viruses (type species tupaia paramyxovirus: other species mossman virus, nariva virus and salem virus) **species beilong virus *subfamily pneumovirinae **genus pneumovirus (type species human respiratory syncytial virus, others include bovine respiratory syncytial virus, pneumonia virus of mice and canine pneumovirus) **genus metapneumovirus (type species avian pneumovirus, human metapneumovirus) *unassigned viruses **j virus **sunshine virus **tailam virus ===notes=== the beilong virus is now known to be a member of the subfamily paramyxovirinae.{{cite journal |author=woo pc, l
