refeed and periodically harvest infected cultures several times before extensive cell destruction stops the formation of new virus. ConclusionIn this necessarily brief report we have discussed certain aspects of the growth of measles virus in simian cell cultures for the preparation of inactivated vaccines. This is not to¡ imply that other sources cannot be used. On the contrary, recent evidence from our and other laboratories indicates that measles antigen can accumulate in avian, canine, or bovine cell cultures under the proper growth conditions. However, because of the vast experience acquired with simians through the use of poliomyelitis and adenovirus vaccines, because of the ex¬ tensive body of information of the cytology of monkey kidney tissue culture, and be¬ cause of its apparent freedom from allergenicity we believe the monkey offers a proved and reliable tissue source for killed measles vaccines. SummaryThe various considerations which led to the use of simian kidney cell cultures for measles vaccine manufacture are briefly discussed. Virulent strains of measles are superior to attenuated strains for the pro¬ duction of antigen.

IntroductionIn areas where the disease is not endemic and the flocks on neighbouring farms are well separated, the most satisfactory method of controlling infectious laryngotracheitis is to dispose of all survivor stock, clean and disinfect the premises and after a period of at least a month restock with uninfected chickens. Such a method was first advocated by GIBBS in 1933. Where the disease is endemic and the poultry flocks on neighbouring farms are within a few hundred yards of each other reinfection commonly occurs and vaccination is the best means of control. BEAUDETTE (1949) and SEDDON (1952) reviewed the control of the disease in the U.S.A. and Australia, respectively, and it is in these two countries that most of the recent research into the control of the disease by vaccination has been undertaken. Thus, in America, BENTON, COVER and GREENE (1958) have shown that a relatively mild virus administered by intranasal drop produces immunity which, at least for a short period, is comparable with that produced by cloacal scarification. HITCHNER and WINTERFIELD (1960) showed that one vaccination by cloacal scarification does not always produce a durable immunity and that revaccination is advisable, for which they advocate the conjunctival drop method. SHIBLEY, LUGINBUHL and HELMBOLT (1963) produced immunity in seven-day-old cockerels by intraconjunctival drop. I n Australia,
