(Reuters) - Walt Disney Co <DIS.N> and Microsoft Corp <MSFT.O> joined a list of potential suitors for Twitter Inc <TWTR.N>, according to media reports on Monday.

Twitter shares were marginally down at $23.33 in after-market trading.

The microblogging service has reportedly started talks with a number of technology companies to sell itself, including Google parent Alphabet Inc <GOOGL.O> and may receive a formal bid soon. A source told Reuters that Salesforce.com Inc <CRM.N> is also in pursuit.

Salesforce is working with Bank of America on a potential bid, a Bloomberg report on Monday said. (http://bloom.bg/2d0WfLi)

Jack Dorsey, who returned to Twitter as chief executive more than a year ago, has been a part of Disney's board since 2013.

Microsoft is also among the list of potential suitors, although Facebook Inc <FB.O> is not likely to have an interest in the social network, CNBC said, citing sources, following the Bloomberg report. (http://cnb.cx/2d4j924)

A sale could occur in the next 30 to 45 days, CNBC reported.

"At this moment, Microsoft has nothing to share," said a spokeswoman for the company.

Facebook declined to comment on the matter while Twitter and Disney were not available for comment.
