MASTITIS 97 



cramps in the legs. The disease was traced to the use 

 of milk from the same herd. This herd comprised 14 

 cows, one of which was proven to be afflicted with mas- 

 titis. Two persons working in the stable were sick with 

 these same symptoms. The same forms of bacteria were 

 found in the faeces of the sick persons that were found in 

 the udder secretion of the diseased cow. 



6. Moro ^^ has reported the following case due to the 

 use of the milk of a goat suffering with a necrotic 

 inflammation of the udder: six persons who had taken 

 the milk in coffee became very sick one to two hours 

 afterward; they had chills, were nauseated and had 

 headache ; 11 hours later colic, vomiting and great thirst. 



7. Lameris and van Harrevelt ^® mention an outbreak 

 of diarrhoea among a number of persons in a hospital. 

 The disease was traced with comparative certainty to 

 the use of milk. This came from a herd in which several 

 cases of streptococcus mastitis were found. The infec- 

 tion probably came from the use of milk from a cow that 

 appeared to have recovered, but whose milk still con- 

 tained streptococci. As the milk was used only after 

 being boiled it was thought that the disease was really 

 due to the presence of toxins, but it is very probable that 

 streptococci may have lived through boiling of milk, as 

 tubercle bacilli have, that is in the film, froth, scum or 

 on the spoon, etc. 



An observation by Edwards and Severn " seems to 

 belong here. It concerns an epidemic of follicular in- 

 flammation of the tonsils which was traced to the milk, 

 probably from one cow, which contained staphylococci 

 and streptococci, which bacteria were also found in the 

 coating of the throat of the affected persons.
