Kirstie Gordon - who impressed in last winter's ICC Women's World T20 before picking up a stress fracture - is brought into the squad after taking eight wickets in the warm-up fixture between Australia and England Women's Academy.
England's warm-up game - against Australia A - ended in victory, with centuries for Tammy Beaumont, Amy Jones and Nat Sciver.
Danni Wyatt and Jenny Gunn, who were a part of the ODI squad, will stay with England Women's Academy to take part in T20s against Australia A and Ireland, the latter fixtures a replacement for Ireland's series against Zimbabwe which as cancelled.
Lancashire's Alex Hartley and Fran Wilson will stay with the Test group in Taunton as cover.
England captain Heather Knight said: "It's obviously a very important match for us and we need to win it to stay in the series.
"The beauty of the multi-format points series means we're still very much in the battle, a normal bilateral series that finished like the ODIs would have been finished but we can get back to 6-4 with a win in the Test match and that's exciting.
"The warm-up at Millfield was ideal. We saw batters get runs and spend time in the middle and the bowlers performed well to bowl out the opposition twice on a flat one. We're raring to go again to get back into the Ashes."
