Fowl typhoid is a septicemic acute or chronic disease of domesticated birds.
The disease is worldwide distributed and natural outbreaks occur in chickens, turkeys, guinea fowl, peafowl, duckling and game birds such as quail, grouse and pheasant.
This can cause mortality in birds of any age.
Broiler parents and brown-shell egg layers are especially susceptible.
The purpose of the Handbook of Poultry Diseases is to acquaint veterinarians and poultry health professionals with current information on the diagnosis and prevention of poultry disease in commercial broiler and egg production flocks in emerging and established industries. Productivity and profitability are enhanced by application of sound principles of bio security, vaccination, and management. Improving efficiency increases the availability of eggs and poultry meat to supply the protein needs of populations in countries with expanding demand.
During the past two decades, primary breeders of broiler, egg and laying strains have eliminated vertically-transmitted diseases from their elite and great-grandparent generations. Unfortunately, infection of grandparent and parent flocks occurs in many developing countries resulting in dissemination of diseases including mycoplasmosis, salmonellosis and reoviral infection.
Improved bio security and an awareness of the need for appropriate vaccination programs, reduces the potential losses caused by both catastrophic and erosive infections on commercial-scale farms, village cooperatives and in integrated operations.

Inoculation with a specific biological substance (antigen) to stimulate resistance or immunity to a particular disease.
Purpose of vaccination
To prevent or reduce problems that can occur from infection of a field strain of a disease organism
To incite high levels of immunity to protect birds in the face of aggressive endemic disease challenges.
To prevent heavy losses in the form of high mortality, morbidity and lowered protective performance by building up resistance in birds
To hyper immunize hens to maximize maternally derived antibody passed through the egg to the hatching progeny.

PREVENTION AND CONTROL OF
COMMON BROILER DISEASES
1
3. Common viral diseases
Marek’s disease
Vaccination is carried out at the hatchery with live virus
vaccine, either heterologous or homologous or both together,
which work to prevent the early multiplication of the field
strain in the body and the later appearance of tumours.
It is well known that 85% of the flock on average is effectively
protected. For this reason we must protect the baby chicks
from an early strong infection of the field virus.
This Marek’s vaccination is not required for all broilers, but is
certainly necessary for the flocks that are killed at an older
age.
4. Gumboro disease
The presence or absence of maternal antibodies will determine
the Gumboro vaccine programme.
It is very difficult to fix the level of passive (maternal)
antibodies in a batch of chicks, since the transmission of
antibodies from the parent flock varies widely.
The absence of antibodies exposes the chicks to Gumboro
disease, whose immunosuppressive effects concerning other
infections (Marek, Newcastle, colibacillosis, and salmonellosis)
are well known.
The vaccination of breeder flocks with inactivated oil–based
killed vaccines, transfers a more uniform and long lasting
passive immunity to the chicks.
5. In farms, create a vaccination program based on the following
principles:
1. in the absence of maternal antibodies vaccinate at day 1,
use a very attenuated live vaccine and repeat again during
the first few weeks –
2. if maternal antibodies are present, vaccinate relative to
the decline in maternal antibodies and the type of vaccine
used
3. if the maternal antibody level is not known or irregular,
vaccinate at day old with a very attenuated vaccine and
revaccinate at 3 weeks.
In known contaminated farms, the use of new strains of
vaccine and a thorough review of the vaccination procedures
have been known to improve results.
Gumboro disease
6. Newcastle disease
Protection can be based on:
1. local immunity in particular area where the virus is very
virulent
2. general immunity in particular area where the virus is
less acute.
The use of attenuated live vaccines, followed by inactivated
oil–based vaccines gives good immunity.
The use of mixed vaccination, an attenuated live together
with an inactivated vaccine at day old gives good results in
countries where Newcastle disease virulence is high.
In countries which are free of the disease, there is no need to
vaccinate, especially for standard weight broilers.
7. Chronic respiratory disease (CRD)
Epidemiologists agree that environmental conditions can cause
a greater problem than the disease itself. However, several
contaminants can intervene together or separately.
1. Infectious Bronchitis virus
Vaccinate at 1 day: the target organ is the Harderian gland.
Spraying a full dose of an attenuated strain (0.5 liters of
water/1 000 doses), as a course droplet has the same effect as
an eye drop and is proven to be efficient.
To avoid destroying the virus by heat, this work is best done
at the hatchery or in the boxes when the chicks are still
confined.
8. 2. Mycoplasma
Mycoplasma gallisepticum is particularly aggressive. Check the
chick quality as well as the possibility of horizontal
transmission to/from other birds/sources. Unfortunately,
serum tests at this early age are not very reliable. Several
cultures must be made to have a statistically reliable result.
Mycoplasma synoviae is also a problem, but to a lesser degree.
In some countries, the vaccination of parent stock with an
inactivated vaccine will produce chicks free of the disease, but
which carry antibodies.
3. Infectious swollen head syndrome (Big Head)
This infection is caused by a pneunovirus and is present in
many countries. A live vaccine can be used for broilers.
Vaccinating breeders with an inactivated vaccine will transmit
maternal antibodies and delay the appearance of the
9. Salmonella
Pullorum caused by Salmonella pullorum/gallinarum only
originates from a contaminated environment. Strict control of
breeding stock over many years has eradicated this problem.
Certain salmonella can also provoke health hazards for the
consumers, notably Salmonella enteritidis and Salmonella
typhimurium.
General hygiene measures, control of the raw feed materials,
backed up by a well coordinated supervisory programme can
be designed to slow down contamination and to separate the
contaminated products from the distribution chain.
Common bacterial diseases
10. Some countries have special rules for salmonella control:
1. specific local standards for poultry houses and equipment
that must be approved
2. investigating contamination
3. compensated slaughter of contaminated flocks by the
state.
Certain countries are considering vaccination. The use of
"competitive flora" has also been proposed to reduce the risk of
contamination
Staphylococcus
Usually located in the leg joints, seldom visceral and generally
caused by accidental injury or skin lesions, which must be
avoided to reduce the incidence of the disease.
Salmonella
11. Control of bacterial infections
Regulations governing the absence of residual chemicals in
slaughtered animals are becoming more and more precise in
many countries today.
The withdrawal periods are becoming longer, which makes it
difficult to give treatment late in the life of the flock.
The use of permissible additives (expectorants, diuretics, etc.)
may limit the problems until slaughter.
The choice of treatment is a veterinary decision. It needs for
good knowledge of the suitability and availability of the
products, an understanding of how to use the product. A bad
choice quite often provokes more losses than that caused by
the illness itself.
