Immunization with Shigella dysenteriae type 1: evaluation of antitoxic immunity in prevention of experimental disease in rhesus monkeys (Macaca mulatta).

The role of serum antitoxic antibody in protection against the dysentery caused by Shigella dysenteriae type 1 (Shiga's bacillus) was studied in monkeys fed 10(10) virulent organisms after parenteral immunization with a formalin-inactivated Shiga toxoid preparation standardized in mice. Two 125-microgram doses of toxoid adsorbed on aluminum hydroxide adjuvant and given 14 days apart provided mice with a 54-fold increase in resistance to parenteral toxin. In rhesus monkeys (Macaca mulatta), the same regimen of toxoid permitted the safe parenteral administration of toxin in incremental doses ranging from 100 to 1,000 mouse 50% lethal doses and resulted in correspondingly high titers of antitoxin in serum. Nevertheless, the immunized monkeys responded to orally administered Shiga bacilli by development of diarrhea and dysentery that was as severe as (or more severe than) the response of unimmunized controls. The failure of extraordinarily high levels of circulating antibody to protect against experimental shigellosis suggests that the intestinal mucosal sites of toxinmediated response are beyond the reach of systemic antitoxin.

Herpesvirus saimiri-induced lymphoproliferative disease in howler monkeys.

Four of 5 howler monkeys (Alouatta caraya) experimentally infected with Herpesvirus saimiri (HVS) developed a rapidly fatal malignant lymphoma accompanied by peripheral T-cell lymphocytosis. HVS was isolated from fresh and tissue cultured blood and tissue lymphocytes and from cell cultures derived from nonlymphoid organs. Humoral antibodies against HVS-induced antigens were detected in the sera of the animals. The in vitro response of the peripheral blood lymphocytes to mitogenic stimulants was depressed following HVS infection.

Attempts to produce gynaecological disease in grivet monkeys with Ureaplasma urealyticum.

Attempts were made to infect grivet monkeys with Ureaplasma urealyticum, including strains freshly isolated from patients with infection of the genito-urinary tact, laboratory reference strains and simian strains. The organisms were inoculated directly into the uterine tubes exposed at laparotomy, or through the cervical canal into the uterine cavity before endometrial curettage; but only colonisation, of up to 5 months' duration, was achieved, without evidence of inflammation in the genital tract or elsewhere, and without an antibody response.

Isolation and biological characterization of an adenovirus of rhesus macaques.

The etiology of a disease in rhesus monkeys the main clinical manifestation of which was acute conjunctivitis of an epizootic character has been studied. The cytopathogenic agent well propagating in primarily trypsinized kidney cells of monkeys has been isolated when investigating the affected eye mucosa. It was not pathogenic for laboratory animals. The mean diameter of the virions is 75 nm, the buoyant density in CsCl is 1.34 g/cm3, the viral DNA density is 1.706 g/cm3. The biological properties and findings of physicochemical, electron-microscopic, and serologic investigations allow one to allocate the isolated agent to the SV-37 strain, a representative of the adenovirus group.
