infectious bronchitis and mixed infections of mycoplasma synoviae and escherichia coli in gnotobiotic chickens. i. synergistic role in the airsacculitis syndrome.the synergistic role of infectious bronchitis virus (ibv) and mixed infections of mycoplasma synoviae (ms) and escherichia coli (ec) in the airsacculitis syndrome was evaluated in gnotobiotic chickens. relative air sac lesion score indexes, in descending order of severity, from various combinations of organisms were: 9.5-ibv, ms, ec; 6.8-ibv, ec; 4.5-ibv, ms; 2.7-ibv; and 0.5-ms, ec. infectious bronchitis virus caused a mild fibrinous inflammation. m. synoviae combined with ibv increased heterop ...19744609905

the histopathogenesis of the nephrosis-nephritis syndrome.chickens were infected with the australian t-strain of infectious bronchitis virus. histologically the disease started as a mild tracheo-bronchitis, accompanied by severe degenerative changes of the renal epithelia and marked inflammatory changes in the intertubular interstitium of renal cortex and medulla and in the propria and submucosa of the ureters and the main collecting ducts. there was a good correlation between the sequence of clinical signs and pathophysiological changes of the disease ...197418777251

the survival of infectious bronchitis (ib) virus in water.observations on the survival of infectious bronchitis virus in 3 mains waters showed that it survived for a much shorter period in one of them which contained a relatively high content of copper (0.2 mg/1). other factors adversely affecting survival were 5 ppm of free residual chlorine and increase in temperature over the range of 20-35 degrees c. survival of virus was prolonged in the presence of 0.1% w/v powdered skim milk (psm), 1,0% w/v poultry mash, 1,0% w/v fresh poultry droppings, rust an ...197318777388
a virus neutralization screening test: its limitations in classifying field isolates of infectious bronchitis virus.a virus neutralization screening test using a 1:5 serum dilution of known antisera against approximately 100 embryo infective doses50 of an unknown virus was used to classify field isolates of infectious bronchitis virus. such a test will detect the major antigen and antibody relationships. the weakness of a screening test is that it does not quantitatively measure the minor antigen-antibody relationships between strains which would be essential to develop a classification scheme for infectious ...197318777389
the combined influence of age of embryo and temperature and duration of incubation on the replication and yield of avian infectious bronchitis (ib) virus in the developing chick embryo.two experiments were undertaken to investigate the combined influence of the age of embryo at infection and the temperature and duration of incubation on the replication and yield of the beaudette strain of ib virus lin allantoic fluid and the chorio allantoic membrane. in general a higher titre of virus was found in the allantoic fluid and chorioallantoic membrane of living embryos than of dead ones and with continued incubation of dead embryos the titre of virus fell still further. for embryos ...197318777405
