The Culex quinquefasciatus Johannesburg strain genome sequence is a joint effort between the Broad Institute and the J. Craig Venter Institute (JCVI). Assembly of 8x shotgun coverage was performed using the Broad's whole genome assembly package ARACHNE. The assembly presented here (CpipJ1, June 2006) consists of 3,171 supercontigs, totalling 580 Mb, with a Contig N50 of 28 Kb and supercontig N50 size of 486.76 Kb.

The Johannesburg (JHB) strain is the source of genomic DNA for the Culex quinquefasciatus genome project. This strain has been selected because it consistently yields high quality chromosome spreads suitable for in situ hybridization studies. This strain is also insecticide susceptible and so can be transported and maintained in laboratories world-wide. The Johannesburg (JHB) strain was established from offspring reared from 20 egg rafts collected in a single unused fish pond in March 2001. Population genetic studies revealed that the Johannesburg C.
