ABSTRACT
Immunoglobulins, or antibodies, are large molecules formed by the immune system, developed by higher organisms to combat the invasion of foreign substances (1). In both humans and animals, the administration of specific antibodies is an attractive approach to establishing protective immunity against viral and bacterial pathogens, and has been prompted by the need to find alternatives to antibiotics in response to the increasing number of antibiotic resistant organisms, as well as organisms that are not responsive to traditional antibiotic treatment (2). There are also individuals who are unable to mount an active immune response against pathogens, including infants, children with congenital or acquired immunodeficiency syndromes, and those rendered immunodeficient by chemotherapy, malnutrition, or aging (3,4), who would benefit significantly from effective passive immunization techniques.
