Single nucleotide polymorphisms at the B1 locus in Toxoplasma gondii detected in feral domestic cat feces in central coastal California.

IUPAC codes designate mixed nucleotide bases (S = C or G, Y = C or T, R = A or G, and M = A or C). A slash (/) indicates that different nucleotides were identified on different sequencing attempts and therefore no definitive base(s) could be reported at that position for some samples.
