Also, our results shows the recovery of L3 viable and infectious from the second week post exposure onward, a prepatent
period shorter than those recorded by Lima et al.

They also do a magnificent job of highlighting the need for standardized non-morphological characters to be used in new descriptions for coccidia, such as location and liming of sporulation, host-specificity, length of prepatent
and patent periods, and resulting pathology of infection with various life stages, and include summaries of how these data have contributed to the recognition or rejection of each taxon within its representative entry.
Considering that the prepatent
period (time from start of infection to time infection is discovered, e.g., person notices strobila excreted in feces) is 2-4 weeks, patients probably acquired infective plerocercoids during February-June.
In this study, asymptomatic infection was found in 8 subjects; however, because there was no follow-up, it raises the question of whether this parasitaemia is detected in the last moment of the incubation period; given the short time between the completion of the prepatent
period and the end of the incubation period (1 day for P.
Most of these immunological tests proved to be sensitive enough to detect fasciolids infection during the prepatent
period in ruminants.
Sarcomas in cats have been reported to develop as early as 4 months and up to several years after vaccination, although in many instances the prepatent
period is unknown .

detection," Veterinary Parasitology, vol.
(15) Additionally, the proguanil analog WR250417 (also known as PS-15) was shown to extend the prepatent
period of P cynomolgi from 8.5 days to 18.3 days in drug-treated monkeys, but did not prevent a primary infection.
