Strongly acid intestinal content and lowered protein, carotene and vitamin a blood levels in Eimeria acervulina infected chickens

Summary

It has been shown that E. acervulina infection in the chicken is attended with a strongly acid reaction of the intestinal content. The protein present in the intestinal wall is affected and therefore carotene cannot be taken up. The carotene, vitamin A and protein concentrations in the blood decrease much. Due to the low protein concentration the liver cannot maintain the normal vitamin A level in the blood. It has been established that these phenomenons begin at an early stage of the infection and the symptoms are observed best by the decrease of the carotene level in the blood.

Zusammenfassung

Die Eimeria acervulina-Infektion bei Kücken geht mit einer stark sauren Reaktion des Darminhalts einher. Das Eiweiß in der Darmwand wird beeinträchtigt, und deshalb kann Carotin nicht aufgenommen werden. Der Carotin-, Vitamin A- und Eiweißgehalt des Blutes sinken stark ab. Im Hinblick auf die geringe Proteinkonzentration kann die Leber den normalen Vitamin-A Spiegel im Blut nicht aufrechterhalten. Es wird festgestellt, daß diese Phänomene schon auf einem frühen Stadium der Infektion auftreten; die Symptome lassen sich am besten an dem verminderten Carotin-Spiegel im Blut beobachten.
