Jorge R. Paredes Thank you so much for the link.

Although the symptoms are slightly different, but I do see similar symptoms around on other leaves.

Appreciate your input.

I would also go with the gall wasp diagnosis. The gall is flat on one side of the leaf, with a small indentation in the center. The other side bulges out and when cut open the developing larva is found inside the gall.

Dear Dr. Mustafa A Adhab

It is gall confirmed (as you already discussed). Just for your information- Galls on trees are caused by insects laying eggs inside or feeding on the branches of leaves of trees and other plants. This usually occurs in the spring. The galls, or tumor-like growths, are produced by the tree in response to chemicals injected into it by an adult or larval gall-making insect.

Regards,

Harun

What is the primary cause of wetwood disease on oak tree?

Bacterial wetwood, also known as slime flux, is caused by an infection of one or more of several bacteria. Enterobacter cloacae (Erwinia nimipressuralis) has been implicated as the cause of wetwood in elm, but numerous other bacteria (including Clostridium, Klebsiella, Bacillus megaterium, and Pseudomonas) have been associated with this disease in other trees. We found in oak trees Klebsiella pneumonia, Pantoea agglomerans, Yersinia enterocolitica and Proteus penneri. Diagnostic has been done by BIOLOG. Looks quite scary... Has anybody found similar species?

Definition of "isolates" in plant pathology?

I have a question on plant disease sampling methods. I plan to collect wilt samples from different farms. I am rather confuse with the term, "isolates". Does 1 fungi isolate represent 1 farm in general? Or, does 1 fungi isolate represent 1 sample tree in that particular farm?

For example, if I collected 3 diseased samples from a farm and I have successfully isolated the pathogen, does that mean I have 3 isolates from that particular farm? If I have visited 3 different farms and similarly, I collected 3 diseased samples from each farm, does that mean I have 3 farms x 3 diseased samples = 9 isolates?

I hope someone could enlighten me. Thanks in advance!
