• reduced formation of phagocytic cups
• 70% reduction in phagocytosis of S. pneumoniae and slightly reduced phagocytosis of H. influenzae
• defective Fc-gammaR mediated phagocytosis
• 80% lethality 2 days after Salmonella typhimurium (gram -) infection at a dose that controls survived
• 60% lethality after Streptococcus pneumoniae (gram +) within 3 days of infection at a dose which controls survived, also massive inflammation of lungs and high levels of bacteria in lungs
• decreased clearance off Haemophilus influenzae and group B Streptococcus
