Bacteria Fisherman Arm Amputated due to Infection!

A 45 years old fisherman was fishing on a bright day. He returned to home happily after catching enough of fish for food. Next day when we woke up his right arm was swollen and very painful. On seeing a doctor, it is found that he developed a rapidly spreading cellulitis which did not respond to antibiotics. Unfortunately, he had to undergo amputation of his limb. The water in which he was fishing was collected for examination and was found that the water had more salinity than fresh water but not as much as that of sea water. What is the cause of his condition?
(please make a diagnosis. varieties of options are not availabe............thanx)

One might be inclined to think its Vibrio Vulnificus or Parahaemolyticus because of this fisherman's association with fish. However the question also gives us the clue that the water isn't clean; more salinity than fresh water.
This also reminds me of a recent case when a man caught a football in a stagnant pond and developed Necrotizing Fascitis, the culprit was Group A Strept.

"the water had more salinity than fresh water but not as much as that of sea water"
This means it is brackish water.
Brackish water is a reservoir of V vulnificus.

this seems really confusing
rapidly progressing cellulitis is Str.pyogens and in this the pain is also out of propotion to symptoms
in V.vulnificus though it is got by eating raw sea fish and oyesters but i dont know tha it can cause cellulitis,though there is vomiting and diarrhea and blistering of skin
so my answer STREP. PYOGENES

Correct Answer Vibrio vulnificus is correcto!!

Dear frens, i am very happy that many of the frens gave us the different ideas regarding water-borne organisms and their consequences.............it was a new idea of S. pyogenes and aeromonas...........thank you.
the answer here is V. vulnificus as explained by Kanishk...............the water having more salinity than fresh water but not as that of sea water is brackish water which is typical for this organism..............in contrast to necrotizing fascitis or cellulitis from Strep. pyogenes, cellulitis due to this organism is very difficult to treat (though antibiotics are available) and hence very often ends in amputation..............It is seen very often in fishermen fishing or shucking oyesters in brackish water.....................thanx.
