A dad who was "too macho" to see a doctor after being bitten in bed by a spider ended up dying from the bite.

48-year-old Luciano Marchioro was asleep in Pato Branco, Brazil, when he was nipped in the leg by the brown spider which was hidden in his sheets.

Marchioro’s son Rodrigo, revealed his dad was bitten on November 3 but "he thought he didn’t need medical attention".

Marchioro’s family claimed his "stubborn refusal to go to the doctor and macho attitude" directly contributed to his untimely death.

Rodrigo, 22, said: “He hated going to the doctors and refused to get it checked out. But after three days, the poison began to affect his legs and started to compromise the functioning of his kidneys.

“It turned out that the infection had spread. At first he thought it was a virus or something but he kept leaving it. After three days of putting it off, his leg was badly swollen and he had not been able to urinate throughout this whole period.”

His heartbroken mother Inelde, 74, wept: “Luciano waited too long and it got too late. He was trying to tough it out like a hard guy, to be all macho and resilient but it was the wrong way to act.

“I want to warn others to watch out for your family members and take care of them. Make them run to the emergency room. If they’re men, don’t let them give you ‘macho excuses’ because they believe it’s the manly thing to do.”

Luciano was referred to hospital in a serious condition and admitted immediately to Intensive Care but died on November 6.

The brown spider is prevalent across several continents and if its venomous sting is left untreated the bite can cause debilitating swelling in the thighs, trunk and arms which can spread to vital organs.
