Hello dear, welcome to Chat Doctor.come have evaluated your query thoroughly.* Pseudocodes infection is considered opportunistic infection.  Which means that the organism only causes disease when a person's immune system is already impaired.* In hospital, the causative bacteria can be spread via the hands of healthcare workers or by hospital equipments that are not properly sterilized. Hope this will clear your query. May his soul rest in eternal peace. Regards.
