Midpoint-rooted neighbor-joining tree with map of New Zealand showing regions and feral cat prevalence data. Subtypes are shown along the right side of the tree. F represents sequences from a recent study in Texas (32) with accession numbers U02422, AY139094, AY139095, AY139096, AY139097, AY139098, AY139099, AY139100, AY139101, AY139102, AY139103, and AY139104. U represents sequences from New Zealand that do not group with a known subtype. Three subtype A Australian sequences are included (AUS1, AUS2, and AUS3). The reference sequences downloaded from GenBank include subtype A: JN-BR1 (D67052, Japan), Petaluma (M25381, United States), PTH-BM3 (AB010401, Japan), SAP03 (AB010404, Japan), Sendai1 (D37813, Japan); subtype B: Aomori2 (D37817, Japan), RP1-A (AJ304988, Portugal), Sendai2 (D37814, Japan), TM2 (M59418, Japan), and TY1 (D67064, Japan); subtype C: CABCpady02C (U02392, Canada), CABCpbar01C (U02393, Canada), DEBAfred (U57020, Germany), TI-2 (AB016026, Taiwan), TI-3 (AB016027, Taiwan), and TI-4 (AB016028, Taiwan); subtype D: Fukuoka (D37815, Japan), MC8 (D67062, Japan), MY2 (D67063, Japan), Shizuoka (D37811, Japan), and TSU104 (AB021111, Japan); subtype E: LP3 (D84496, Argentina) and LP20 (D84498, Argentina). Numbers are bootstrap values based on 1,000 replicates.
