Table 2 Isolates with potential inter-assemblage recombination within loci

From: Population-based analyses of Giardia duodenalis is consistent with the clonal assemblage structure

Source (Isolate ID)

Locus

Mixed

Reference

Nested-PCR

Description

Cattle (K2521)

GDH

A/E

DQ182604 [37]

Yes

18SRDNA sequence of this rectal faecal sample was identified as Ass E. Other study samples contained Ass AI, AIII or Ass E.

Surface water (R24)

GDH

A/B

EU350516 [38]

Yes

Environmental water sample,which contained very few cysts.

Human (D6)

TPI

B/E

EU272164 [39]

Yes

Faecal sample derived from rural community in Egypt, where people commonly live in close contact with their livestock.

Cattle (K4016)

GDH

Is Ass AIII

DQ182607 [37]

Yes

AIII is excluded as recombinant from AI and AII as they latter two could not be identified as parental strains.

Cat (Swecat171)

GDH

Is Ass AIII

EU769223 [14]

Yes

 
  1. DNA sequences presented in this table were all generated by a (semi)-nested PCR for GDH [40] and TPI [41]. All these isolates were identified previously as potential recombinants [26].
