Synopsis
CAPC Recommends Continuing to monitor the health of the pet for those dogs that test positive for Cryptosporidium spp. on annual wellness fecal testing. Diagnosing and treating any underlying conditions that may be weakening the animal’s immune system or causing stress, which can allow Cryptosporidium species to multiply.
Disease
Cryptosporidiosis is a self-limited, small bowel infection characterized by secretory diarrhea. Fluid loss may be severe in clinical cases.
Prevalence
Seroprevalence along with microscopic identification and PCR-based diagnostic studies indicate that Cryptosporidium infection is relatively common in dogs. Confirmation of current infection by fecal examination is infrequent; commonly seen in only 1% to 5% of cases.
Diagnosis
Diagnosis can be difficult. Specimens should be sent to an academic or commercial testing laboratory familiar with the necessary diagnostic techniques.
Treatment
Treatment is difficult and few drugs are consistently effective against Cryptosporidium . Symptomatic patients may require treatment, particularly if clinical signs are severe or persistent.
Control and Prevention
Due to the low infective dose and persistence of oocysts in the environment coupled with the lack of effective treatment, control and prevention should be focused on reducing environmental contamination with infectious oocyst and should consist of: Promptly picking up and removing feces to prevent fecal contamination of the environment. Cleaning with heat or steam followed by disinfection and drying to promote desiccation, may be useful.
Public Health Considerations
The zoonotic risk of all recognized Cryptosporidium species and genotypes is not known. However, 19 species and 4 genotypes have been identified in humans (See “Zoonotic Potential of Valid Species and Genotypes of Cryptosporidium ” for more information).
