Blood cultures should also be performed in children with suspected lung abscess.There is often a close working relationship between clinicians caring for patients with cystic fibrosis and laboratory scientists. As such, it needs to be constantly tested to determine whether the defined properties of each class actually extend to all of the members of the class, and whether the hierarchy of the classes is true. For the most part, pathologists see hyphae or yeast forms, and these forms and most of the many species of infectious fungi can look more or less equivalent when observed in tissue. Rhodococcus equi and Arcanobacterium haemolyticum, formerly classified in the genus Corynebacterium, are members of the loosely defined taxon "coryneform" bacteria. Arcanobacterium hemolyticum is a β‐hemolytic Gram‐positive, pleomorphic, facultative anaerobic, non‐acid‐fast rod that has been implicated as an etiologic agent of non‐streptococcal pharyngitis, especially in adolescents and young adults, as well as a cause of skin and wound infections, osteomyelitis, sepsis, and central nervous system infections.

The usual manifestation is a skin infection or pharyngitis. As a partial remedy for this situation, pathologists have discovered a wide range of subtle clues that may help them distinguish one fungus from another: width of hyphae, angle of hyphal branching, septation of hyphae, the presence or absence of pigment, the size of yeasts and the morphology of budding, the type of host response to the fungal organisms (e.g., granuloma, acute inflammation), the anatomic site of infection, and so on. Arcanobacterium haemolyticum: Agent mostly causes pharyngitis or soft tissue infections. The incubation period is unknown, although long-term pharyngeal carriage has been identified.

This organism may be part of commensal flora of the respiratory and gastrointestinal tracts.It has also been associated with septicemia, septic thrombophlebitis (Lemierre’s syndrome), tonsillar abscesses, pneumonia, empyema, otitis media, sinusitis, ocular infections, peritonitis, chorioamnionitis, endocarditis, brain abscesses, subdural empyema, skin/soft tissue (cellulitis, necrotizing fasciitis, omphalitis, venous ulcers), and bone/joint infections.
