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.
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.
Hybrid speciation may have produced Heliconius butterflies, but that is disputed. [20] Family Papilionidae. Genus Battus. The Coeruloaurean swallowtail is a hybrid produced by a Pipevine swallowtail (Battus philenor) mating with a Goldrim swallowtail (Battus polydamas). [21] As the ranges of these two species overlap, the hybrid can be ...
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 dangerous bleeding ...
Up to 80 percent of dogs infected will have symptoms, but the mortality rate is only 5 to 8 percent. [5] Infectious canine hepatitis is a sometimes fatal infectious disease of the liver. [6] Canine herpesvirus is an infectious disease that is a common cause of death in puppies less than three weeks old. [7]
Two complex chimpanzee blood group systems, V-A-B-D and R-C-E-F systems, proved to be counterparts of the human MNS and Rh blood group systems, respectively. Two blood group systems have been defined in Old World monkeys: the Drh system of macaques and the Bp system of baboons, both linked by at least one species shared by either of the blood group systems.
The animal kingdom is full of creatures with excellent memories because having a good memory increases their chance of survival. Some of the animals with the best memories are dolphins that can ...
Hemophilia is much more common in males than females because males are hemizygous. They only have one copy of the gene in question and therefore express the trait when they inherit one mutant allele. In contrast, a female must inherit two mutant alleles, a less frequent event since the mutant allele is rare in the population.
