The microbial growing is suspected, by inconspicuous hemolytic zones at 24 hours (h) of incubation at 37[degrees]C on bovine blood agar, thereafter at 48 h and with an exhaustive macroscopic examination, it is possible to see white pin point colonies with 1-2 mm diameter, surrounded by a more prominent total ([beta]) hemolysis [9, 46, 57], it is partially acid-alcohol resistant and has a fermentative metabolism ; unlike clinical samples, cultures do not have a characteristic odor; CAMP test is helpful to confirm the identification [13,31] and differentiation from Arcanobacterium haemolyticum, which inhibit Staphylococcus aureus [beta] haemolysin
13] Virulence factors like haemolysin
production and presence of fimbriae in Escherichia coli may be associated with urovirulence.

Characterization of a haemolysin
from Mycobacterium tuberculosis with homology to a virulence factor of Serpulina hyodysenteriae.
Association between the presence of Enterococcal virulence factors gelatinase, haemolysin
and enterococcal surface protein and mortality among patients with bacteremia due to Enterococcus faecalis.
Effects of medium composition, calcium, iron and oxygen on haemolysin
production by Plesiomonas shigelloides isolated from water.
lugdunensis strains carry the delta-like haemolysin
Characterization of a new termostable direct haemolysin
produced by a Kanagawa-phenomenon-negative clinical isolate of Vibrio parahaemolyticus.
The study also showed significantly higher number of biofilm forming isolates produced haemolysin
and coagulase in comparison to planktonic isolates, however biofilm forming isolates were significantly lower producers of protease in comparison to the planktonic isolates.
Dermatophilus congolensis produces virulence factors such as haemolysin
, phospholipases, ceramidases and proteolytic enzymes, which may be used to penetrate epidermal barrier and interact with inflammatory response of host (How et.
The pathogenicity of Vibrio parahaemolyticus and the role of thermostable direct haemolysin
and related haemolysins

expression were observed in a strain of Salmonella enterica serovar Typhimurium and Congo red binding activity, On the other hand the result agreed with Chart et al.
