Henneguya sp. in yellowfin goby Acanthogobius flavimanus from the San Francisco Estuary

Table 1 Prevalence of myxozoan infections from yellowfin gobies as determined by PCR

Number of fish	Total	Mortality	Histopathology	End of study	PCR	Myxozoan prevalence (%)
Group 1	151	18 (11.9%)	10 ^a	123^*	30/30^**	100
Group 2	55	0	15 ^a	40^*	15/15^**	100

^aSections were variable for myxozoan spores but difficult to confirm for vegetative stages by histopathology.
^*Fish remaining at termination of the study at 1 month from which fish were randomly collected for PCR testing for presence of the myxozoan.
^**Number of fish positive for the myxozoan per number of fish examined.
