Conjunctival swabs collected in 1991-92 from 333 pedigree and non-pedi
gree cats were tested for the presence of Chlamydia spp. antigen using
an ELISA antigen kit. Forty (18.4%) of the 217 samples from cats with
conjunctivitis were positive. Seven (6%) of 116 samples from cats whi
ch were in contact with cats with conjunctivitis but which showed no c
linical signs at the time of sample collection were positive. Positive
-testing cats were frequently from multi-cat households. Chlamydia spp
. is present and associated with conjunctivitis in cats in New Zealand
. Infection may occur concurrently with viral diseases. Feline caliciv
irus was recovered from 27 (21 with conjunctivitis) of 37 cats tested
in five catteries. Four cats (with conjunctivitis) were FIV-positive.
