The announcements come after a loss of confidence in Infantino's leadership following an attempt to sell stakes in FIFA competitions to private investors.
Wales became the first nation to publicly withdraw support for FIFA president Gianni Infantino's re-election bid on Monday, citing "failures in good governance, process, leadership."
The announcement came after a loss of confidence in Infantino's leadership after an attempt to sell stakes in FIFA competitions to private investors, with the Welsh FA saying it would not back Infantino's candidature for the 2027-2031 term.
"Failing to put the best interests of football first is a failure we cannot accept," the Football Association of Wales said in a statement.
The election is to be held in Rabat next March.
Serbia and Sweden have also since announced that they are withdrawing support for Infantino's re-election.
"The Football Association of Serbia has withdrawn its support for Gianni Infantino for a new term as President of FIFA," the Serbian FA said in a statement posted to social media on Monday.
"We would like to remind you that we provided Mr Infantino with our support in writing on 25 May this year, but after carefully considering the events that have seriously damaged the standing and reputation of both FIFA and its president in the past period, this is the only logical and rational course of action," it added.
Announcing its decision, the Swedish Football Association said: "At an extraordinary board meeting held on Monday, the Swedish Football Association (SvFF) decided not to support FIFA President Gianni Infantino in his upcoming re-election bid."
"This follows a lengthy assessment of developments within FIFA and the organisation’s leadership," it continued. "The decision is based on recurring shortcomings in management, transparency and governance, which mean that confidence in Gianni Infantino’s leadership no longer exists".
It comes after FIFA announced on Saturday that it was dropping plans to allow private investors to purchase stakes in major competitions following fierce pushback.
In a statement, Infantino said the project had "created divisions" that were "no longer in the interest of the objective set out in the first place."
"Our purpose has always been - and will always be - to unite and improve. As a result, this proposal will not proceed," he added.
The football world governing body had outlined a proposal in late July that it said would increase funding to its 211 member associations through a new subsidiary running its commercial operations and events, including World Cups.
Dubbed the FIFA Forward Enterprise (FFE), the venture aimed to cash in on what Infantino described as the sport's "remarkable commercial value" by inviting third parties to take minority, non-controlling investments in the new entity.
FIFA said FFE could raise up to $4.2 billion (€3.6 billion) based on an initial equity valuation of $20 billion (€17 billion).
In a statement on Saturday, European governing body UEFA said it welcomed FIFA's decision to shelve the proposal, adding that it would now work with its associations and other confederations to "devise a plan" to ensure such a situation did not occur again in the future.
"We cannot keep going on like this with secret schemes on fast track timescales, cooked up by faceless individuals and of dubious benefit to the game. We must identify those responsible and hold them to account," UEFA said.
"The current FIFA leadership has not only lost UEFA's confidence but also that of many other members of the football family."
