Eggs hatched from MG infected birds

[Glenda L Heywood]

I want to make a statement here about this idea
on the long post on MG flock one person made this state,emt

THE POSTER SAID THIS
PLEASE READ IT ALL

I share your pain. I'm 90% sure my flock is also infected. I've culled off
my remaining silkies but cannot bring myself to cull off my original hens.

I also know where and whom the disease came from. It is a member
(inactive) of BYC. I didn't use basic biosecurity so it's my fault.


I continue to hatch eggs but the chicks stay inside my house and are
given away ASAP.




GLH replied here

Well this is not true that you are not giving away MG infected chicks

you see the EGGS hatched come from your flock and in your incubator you will have the MG germs
whether you keep the chicks in the house
It is not actually where they get the MG.

first place you will carry it in to the house on your clothes and shoes and your hands from feeding and gathering the eggs

second the eggs will send it thru to the chicks hatched in the incubator

third you do take a big responsibility for giving away these chicks

you might as well keep them your self

biosecurity starts with cleaning up the infected birds and disinfecting all areas they may have been on

quite a large responsibility
so if restocking the premisis of your farm with new chicks declared MG free you must really disinfect the whole farm area

to do this is a very large project
MG germs stay active for a long time

Also the joining NPIP is vry good as they can test for pulluroum typhoid and MG free flocks

so give some thought to the hatching egg thing

any question as to my statements email me PM

Acually, thats not true. According to this article:

http://www.cfsph.iastate.edu/factsheets/pdfs/avian_mycoplasmosis_mycoplasma_gallisepticum.pdf


and I quote: "Micoplasmas are typically fragile and only survive in the environment for a few days; birds can be re-introduced after 2 weeks." They do recommend thoroughly cleaning and disinfecting the poultry premises.

I
it is a known fact that MG flocks that lay eggs
and then the eggs are hatched will spread the MG thru out the hatched chicks

Dr Ron Okimoto thoughts on MG

Mycoplasm is not a serious problem to the fancy unless you also have other diseases in your flock. Mortality is a little higher and egg production is decreased, but your flock will survive it.

This is the main
reason that nearly all purebred backyard flocks have mycoplasm. Once you have it you can't really get rid of it unless you are willing to disinfect your property and treat all your birds with a strong
antibiotic. Baytril seems to work, but all it takes is for one bird to retain the mycoplasm and you have it again.

Nearly all fancy breed birds that I have tried to bring in, test positive for mycoplasm either MS or MG
or both. So if you do manage to clean up your flock you have to quarantine, test and clean up any bird before you introduce it into your flock.

You test for it by sending a blood sample to your state testing lab and ask for the mycoplasm MS and MG test. To test whether your birds are clean if they have already had mycoplasm and been treated with antibiotics, the antibody test will still test positive.

You have to do a more expensive PCR swab
test to tell you if you have been successful. Your state lab may not do this test, and you will have to look around for someone that will.

The best way to clean up your flock would be a generational replacement. You clear all your old birds
out and disinfect the pens. You raise the new chicks at a clean facility and treat them with Baytril
imediately after hatch. We did this for two lines treating around 600 total chicks and it worked.

Even though their parents had mycoplasm, none of the chicks tested positive after treatment for 8 days on Baytril. We used twice the recommended dosage (check with a vet) and treated the chicks with vitamin and electrolytes after the 8 day treatment.

READ THIS GOOD
Mycoplasm is transferred through the egg at a low frequency (1% to 10%). The older the bird the lower
the frequency, but all it takes is one infected chick and the entire brooder gets infected, and as long as
you have infected birds on your property the other birds are bound to get it eventually.

I wouldn't worry about it unless other diseases are a problem in your flock. Mycoplasm weakens the bird, but it doesn't weaken most birds enough for people to work hard to erradicate it.

Commercial birds are free of it because any decrease in viability and egg production is a decrease in profits, but most backyard flocks aren't managed for maximum production. Commercial breeders would be happy if the fancy erradicated mycoplasm so that it would infect their birds less often.

The reason I would throw eggs away
I do hope that you will evade the MG
as it can be carried in recovered birds for yrs
and then when they are sold to some one who has never had it all will be infected with in 10 days to three weeks after getting infected birds


GLH replied
the MG birds will live after recovery and you would not realize they have MG
but it is passed to all eggs in the incubator from infected eggs
and the fact that the lady did not know that her hens had it causes me to feel she passed it on to the egg shells as she gathered them and carried it on her feet or clothes to the other hens
just my experience with the MG
The oxine she is using is the best in disinfectants
it has been thourghly tested to work

so do disinfect the incubator good
use the Oxine it will cure the MG premisis

Mycoplasma Gallisepticum (MG)

Contagious disease of poultry, gamebirds, pigeons, and passerine birds of all ages. Younger birds are more susceptible than older or mature birds. At one time the most common means of MG spreading was by trans ovarian passage from infected breeders. Today, however, breach of sound management and biosecurity measures is more often the cause.

MG can spread within the poultry house by direct bird to bird contact and by exhaled respiratory droplets (indirect contact). Clinical signs may be slight when uncomplicated. Sticky exudate from nostrils, foamy exudate in eyes, and swollen sinuses. Airsacculities with yellow exudate in air sacs. Infected birds develop respiratory rattles, sneeze and flip their heads.

Many infections display similar symptoms especially cold type symptoms. It is a mistake to presume that every bird with rattly breathing or other cold like symptoms has MG. Without a proper lab test one sometimes cannot be really certain what the infection is.

May spread slowly through a flock or maybe acute. Affected birds often are stunted and unthrifty. Infection can be acute in an individual bird, but take considerable time to spread throughout a flock. Recovered birds remain carriers.

Treatment is erythromycin, tylosin, spectinomycin and lincomycin. Tylosin consistently gives good results. Administration of most of these antibiotic is by feed, water or injection.

Halo, from that same article you quoted:



Transmission
M. gallisepticum is transmitted during close contact between birds as well as on fomites. Aerosol spread occurs over short distances and can be responsible for transmission within a flock. M. gallisepticum is also transmitted vertically in eggs.

The first is from my friend Dr Okimoto

no this is from another article
I forgot to put the url in
sorry
just trying to emphsise the symptoms

2nd is from
www.ruleworks.co.uk/poultry/M-Gallisepticum.htm - 12k

I must say this I personally did contact MG from a Duccle at a poultry show and had to dispose of all my breeding flock
so I do know that a sick snoting bird does carry MG and when shaking the snot from the head it spreads to other birds
I had to cull all of them myself very sad and stressful thing to have to do

if you feel I should remove the 2nd article just PM me
as I was only posting the symptoms
