Phototherapy for neonatal nonhemolytic
Pasteurella haemolytica infections in healthy rocky mountain Bighorn sheep (Ovis canadensis canadensis): influences of sample site and handling.
If there is a hemolysis in the form of transparent zone around the colony in blood agar, it is called as beta; if there is a partial hemolysis with the greenish zone, it is called as alpha and if there is no hemolysis, it is named as nonhemolytic
. Beta-hemolytic Streptococcus types are those responsible for most significant clinical tables in humans and this group is divided into more than 20 serogroups (A, B, C etc.) compared to C antigen on the cell wall.
agalactiae, there is a nonhemolytic
fraction of SGB strains that hinder detection by the traditional method.
When culturing at 35[degrees]C was performed, medium-sized, convex, sticky, nonhemolytic
colonies formed on blood agar and pinpoint colonies with pitting on chocolate agar.
Febrile reactions (33% of all adverse reactions) reported in this study, with regard to their clinical evolutions, were concordant with febrile nonhemolytic
transfusion reactions (FNHTR).
Immune-mediated reactions can be further divided into hemolytic and nonhemolytic
reactions consisting of febrile and allergic reactions.
were observed on Brucella selective agar media after 3-5 days of incubation as small, translucent, dewdrop-like, round, and convex with smooth margins (Figure 2) and the cultural characteristics on blood agar whitish-grey, punctuate, shiny, nonhemolytic
, and convex colonies were observed (Figure 3).
Other rare reaction against transfusion observed in all patients are acute hemolytic reaction, allergic reaction, anaphylactic reaction, coagulation problems in massive transfusion, febrile nonhemolytic
reaction, metabolic derangements, mistransfusion (transfusion of the incorrect product to the incorrect recipient), septic or bacterial contamination, transfusion-associated circulatory overload, transfusion-related acute lung injury, urticarial reaction, delayed hemolytic reaction, posttransfusion purpura, transfusion-associated graft-versus-host disease, transfusion-related immunomodulation, and infectious complications .
Three sets of blood cultures obtained on admission showed microscopic, nonhemolytic
colonies on blood agar plates.
Coli, and various Streptococcus species (peptostreptococci, nonhemolytic
streptococci, microaerophilic streptococci, and [beta]-hemolytic streptococci of groups A, B, and C) [2, 3].
The effect of prestorage WBC reduction on the rates of febrile nonhemolytic
transfusion reactions to platelet concentrates and RBC.
