Haemophilus influenzae (formerly called Pfeiffer's bacillus or Bacillus influenzae) is a Gram-negative, non-motile, coccobacillary, facultatively anaerobic, capnophilic pathogenic bacterium of the family Pasteurellaceae.
H. parainfluenzae biotypes I and II are capable of natural genetic transformation. [3] Natural genetic transformation is a bacterial adaptation for DNA transfer. In order for a bacterium to bind, take up and recombine exogenous DNA into its genome it must enter a special physiological state termed natural competence.
Hemophilia, or haemophilia, is an X-linked recessive disorder that impairs the body's control over blood clotting. Haemophilia A and Haemophilia B arise from mutations in the genes for factor VIII and factor IX, respectively. [6] Females with this disease are almost exclusively unaffected, obligate carriers.
Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
WASHINGTON (AP) — U.S. officials on Thursday approved drugmaker BioMarin's gene therapy for the most common form of hemophilia, a $2.9 million infused treatment that can significantly reduce ...
[2] [3] In most species with XY sex determination, an organism must have at least one X chromosome in order to survive. [4] [5] The XY system contrasts in several ways with the ZW sex-determination system found in birds, some insects, many reptiles, and various other animals, in which the heterogametic sex is female.
Over 13 canine blood groups have been described. Eight DEA (dog erythrocyte antigen) types are recognized as international standards. [3] [4] [5] Of these DEA types, DEA 4 and DEA 6 appear on the red blood cells of ~98% of dogs. Dogs with only DEA 4 or DEA 6 can thus serve as blood donors for the majority of the canine population.
MHC-based sexual selection is known to involve olfactory mechanisms in such vertebrate taxa as fish, mice, humans, primates, birds, and reptiles. [1] At its simplest level, humans have long been acquainted with the sense of olfaction for its use in determining the pleasantness or the unpleasantness of one's resources, food, etc.
