Nelly , Columnaris est omniprésent dans cette région où une section dédiée à cet agent
pathogène sera parfait .
Les pratiques durables pour contrôler / éviter pathogènes des poissons (par exemple
virulente Flavobacterium ) est le mieux pour l'Afrique de l'aquaculture .
Drs . Arias & Haitham Mohammed a récemment présenté une nouvelle bio- agent pour
Flavobacterium dans rencontrait ( Nouvelle-Orléans ) . Et , je pense que ce sera présenté
en détail lors de cette conférence .

Evans, We do cover this problem in our field training, scheduled for end of July.
The worst problems with columnaris tend to come in cool season, usually July in Ghana but
I think it is getting to be year around. Those who grow out fry in concrete tanks in
Ghana have found that disinfecting the tanks in between crops help a lot. They use
hydrated lime and just about paint the tank with it.
For fish being held in hapas, it is much more difficult. Still, antibiotic treatment via
feed is best. Dr. Arias’ lab prefers florfenicol, sold as Aquaflor. We have also had some
success with chloramine T bath.
The key thing about flavobacterium is how well it can avoid chemical treatments by hiding
deep into a biofilm. It attaches very well to PVC pipe and various types of netting.
I attach the field training announcement for this year. Will post the registration link
shortly.

Dear Karen,
As indicated by Naga, this is a real problem here in Ghana and in East Africa as confirmed
by Br. Walakira.
My question is How do we tackle it for now? Until we come for the workshop in October,
shall we continue to see our fishes die? Is there any solution we can adapt until then?

Dear Karen
This workshop will be very needful for current situation in Ghana.
Columnaris is at its peak virulent stage in Ghana. It became so deadly causing mortality
in fingerlings from 10-80% based on location of farm.
On the Volta River after Akosombo and Akuse dam the problem is not much severe except few
cases with less than 10% mortality but on main Lake its up to 80%.
The mortality starts from 4th day after stocking and continues till 9th day by when the
damage is too high. 100% fingerlings will have sickle back and confirmed columnaris.
No clue how to stop. All farms blame hatchery operators and squeezing us for
replacement.
I hope this workshop will help us to solve problems in Ghana.
If possible please conduct some program in Ghana to enlighten farmers in Ghana.
With Regards
Murali

Will, can you please post this to Sarnissa?
Flavobacterium is the causative agent of columnaris disease that affects many species in
many different environments. Lately there are strains identified that are very
pathogenic. It should be quite an interesting subject for researchers in Africa, because
I have seen signs of columnaris disease in most clarias and tilapia hatcheries that i have
visited. Even for us here in Auburn, it a very problematic pathogen. Dr. Arias' lab
including Dr. Haitham Mohammed from Egypt) has been working with this pathogen for some
years now and from looking at the past venues of this conference, so have many other
labs.

Flavobacterium est l'agent causal de la maladie de columnaris qui affecte de
nombreuses espèces dans de nombreux environnements différents. Dernièrement il ya souches
identifiées qui sont très pathogène. Il devrait être un sujet très intéressant pour les
chercheurs en Afrique, parce que je ai vu des signes de la maladie dans la plupart des
columnaris clarias et écloseries de tilapia que je ai visités. Même pour nous ici à
Auburn, un agent pathogène très problématique. Le laboratoire du Dr Arias dont le Dr
Haitham Mohammed de l'Egypte) a travaillé avec ce pathogène depuis quelques années
maintenant et en regardant les dernières salles de cette conférence, ont donc beaucoup
d'autres laboratoires.
