Figure 8. — Correlation of pup deaths from malnutrition 

 with death from malnutrition and enteritis, St. Paul 

 Island, 1964 and 1966-69. 



Malnutrition was a secondary cause of death 

 in two cases each of enteritis and cause unde- 

 termined; in one case each of hookworm 

 disease, perinatal complex, bite wound, and 

 hemorrhagic gastritis; and in three pups un- 

 suitable for examination. 



Hookworm Disease 



The percentage of deaths from hookworm 

 disease in 1969 for all study areas combined 

 was 27.9, or 11 percent more than in 1968, 

 although the number decreased from 64 to 58. 



For the 3d consecutive year that area 3 on 

 Vostochni Rookery at Northeast Point has been 

 used as a study area, the death rate there from 

 hookworm disease has been much higher than 

 in areas 1 and 2 on Reef Rookery (table 5). 



Microbial Infection 



The most prevalent form of microbial in- 

 fection was omphalophlebitis (navel infection) 

 and peritonitis, the primary cause of death in 

 11 and 6 pups, respectively. Enteritis was the 

 primary cause of death in 2 pups and a sec- 

 ondary cause in 13 pups that died of malnu- 

 trition. Infection was a secondary cause of 

 death in 7 of 10 pups that were severely bit- 

 ten.
