Onchocerciasis in Cattle and Associated Animals. 33 



A.DDENDUM 2. 



Since i he foregoing has been printed, I have received from Dr. 

 L. de Blieck, Director of the Government Veterinary School at 

 Buitenzorg, Java, a statement by Dr. Sniit of the results of the 

 enquiries made by the Dutch authorities at my request, into the 

 occurrence of worm nodules in Netherlands India. 



The following is a translation of this report : — " I have often 

 observed the ' worm-nodules ' caused by Onchocerca gibsoni at tho 

 abattoir at Buitenzorg. They have been seen in native as well as 

 in cross-bred cattle (i.e.. of native with European, Australian, 

 and Bengal (Zebu) cattle). They have been mostly found in cattle 

 originating from Gombong, and Poerworedjo, principally in 

 Javanese cattle. Several times, however, they have been seen in 

 animals originating from the Buitenzorg district and Bantam, also 

 in cross-bred Australian and in the few Australian cattle killed at 

 Buitenzorg. 



" At Batavia, Mr. Jenne found them to occur in nearly every 

 animal killed (these being imported Australian). 



" In native cattle they were only found in the breast muscles; in 

 Australian cattle at Batavia, however, they were found also in the 

 abdominal muscles in front of the stifle. 



" Out of about 4000 karbouws inspected, two were found to have 

 one worm-nodule each — in both cases in the breast muscles — which 

 macroscopic-ally differed in no way from the worm-nodules in cattle. 

 It is seen from this, that they .only very rarely occur in karbouws. 

 Mr. Sohns was able to inform me that they have been repeatedly 

 found by him in the residencies of Rembong and Kediri, in the 

 breast muscles of native cattle. He also found them in the karbouws. 

 but only very seldom. 



" Finally, it may be stated that Mr. de Does a short time ago 

 personally intimated to me, that he had also seen them in cattle at 

 Poeloe Laoet, an island at the S.E. point of Borneo. 



" Briefly stated, it may therefore be accepted that worm-nodules 

 caused by Onchocerca gibsoni occur over the whole of Java in native 

 as well as cross-bred native cattle, and in karbouws. Further, that 

 the said disease has also been found on other islands (Poeloe Laoet) 

 of the Archipelago." 



The term, native cattle, employed in Dr. Smit's report, cannot 

 obviously refer to the original wild ox of Java, the Bantin (Bos 

 (Bibos) banteng). It is, however, undoubtedly applied to animals 

 of the Bos indicus type bred in Java, and possibly the direct
