Abstract
Most human cases of cryptosporidiosis are caused by Cryptosporidium parvum or C. hominis, but pathogenicity of some unusual Cryptosporidium species/genotypes is uncertain (1). In July 2008, an outbreak caused by Cryptosporidium rabbit genotype was linked to consumption of tap water in Northamptonshire, England (2). On June 23 and 24, Cryptosporidium oocysts were detected by operational monitoring of treated water at a surface water treatment works. A precautionary boil-water notice was implemented on June 25.

To the Editor: Most human cases of cryptosporidiosis are caused by Cryptosporidium parvum or C. hominis, but pathogenicity of some unusual Cryptosporidium species/genotypes is uncertain [1]
Cryptosporidium oocysts were detected by direct immunofluorescent antibody test (IFAT) (CryptoCel; TCS Biosciences, Buckingham, UK) in large bowel contents from a rabbit carcass removed by the water company from a tank at the water treatment works
Cryptosporidium species were identified by bidirectional sequencing of PCR products generated by nested PCR for the small subunit (SSU) rRNA gene [5] from 4 DNA aliquots of each sample
Summary
Rabbit Genotype, a Newly Identified Human Pathogen To the Editor: Most human cases of cryptosporidiosis are caused by Cryptosporidium parvum or C. hominis, but pathogenicity of some unusual Cryptosporidium species/genotypes is uncertain [1]. Rabbit genotype was linked to consumption of tap water in Northamptonshire, England [2].
