Actinobacillus Infection in Cattle Symptoms, Treatment and Prevention

 

Actinobacillus is also known as a wooden tongue disease and it is also the non motile facultatively anaerobic bacteria that belongs to the family pasteurellaceae and more than that these bacteria are commonly found as a normal flora in the respiratory and oral cavities of the animal but some species can act as the opportunistic or the primary pathogens and it is highly significant in veterinary medicine because it cause the economic losses in the livestock.

Etiology:

The etiology of the actinobacillus is described below in the following points:

·      It is caused by the actinobacillus lignieresii

·      It is normally found in the upper GIT

·      It is known as the opportunistic bacteria

·      It is also known as the pyogenic bacteria

·      Entry through the injury in deep soft tissues

·      It is the gram-negative bacteria

·      Cocco bacillus and nonmotile and noon spore forming bacteria

·      It is the aerobic bacteria

·      Normal Flore of upper GIT and respiratory tract

Clinically characteristics:

As we know that the there are some of the main and one of the major clinical characteristics of this disease is very watchable and that one is the chronic pyogranulomatous inflammatory condition and enlarge regional lymph nodes and this all about the clinically characteristics of this disease.

Epidemiology:

As we know that the epidemiology is the explanation related that where is the disease most common and other than that it is present in which type of animals other than that it lives how many days and most probably where it lives so here we also discuss all about this for the more and important information and that information is that it is most common in the sheep and cattle and it is also the endemic in Scotland and more importantly it can not live more than 5 days on hay or in the straw.

Transmission:

As it is the normal inhabitant and the opportunistic bacteria so when an injury occurs in the buccal cavity due to some of the sharp things or the fibrous food and it enters into the soft tissue deep and cause pathogenesis.

Risk Factors:

Following are some of the risk factors which were given below:

·      First one is the abrasive pasture

·      Second one is the puny awns 

·      Third factor is the dry, stemming and tough hay laze

·      Last and the fourth one is the cu-deficiency

Pathogenesis:

The pathogenesis of the actinobacillus is described briefly below in the paragraph as we know that this disease is also known as the wooden tongue and that is why it is start from the tongue so first the tongue is become injured and after the injury of the tongue the entry takes place and after the entry of the bacteria the first one is the glossitis in which the animal is having the no feed intake after this there is also the no mastication done by the animal then other than this there is also the granulomatous lesion present and know the second one is the regional lymphadenitis and after this one there is the third and the last one and that will the visceral involvement also occur and this all about the pathogenesis of the actinobacillus.

Clinical Signs:

Following are some of the clinical signs which are present according to the animals and they all are given below:

·      First one is the cattle and, in the cattle, they are unable to eat and that is simply called the hyper salivation

·      There will be the gentle chewing as the tongue will be the swollen and hard

·      Nodules and ulcers are present on the tongue

·      Lymphadenitis is present

·      Cutaneous actinobacilloses on skin and the cheeks also occur

·      In sheep the tongue is not usually involve and lesions is up to the 8cm on nose and face and most importantly occasionally the mastitis is also occur

Diagnosis:

As we all know that the diagnosis is one of the main role in the disease as if we are not able to diagnose the disease properly so we are not able to treat the animal correctly because the treatment is fully dependable on the diagnosis so if we are able to diagnose correctly so we are able to done the correct treatment so in the diagnosis we first taken the history of the animal in which we ask the owner about the history of the feed also where the animal is living like the management of the animal and most importantly the water routine of the animal in which we check that the water which is available to the animal is fresh or not and other than that we also check the presence of the bacteria in discharge and the after this we also see the clinical signs of the animal it also plays the most important role in the diagnosis of the disease and in last the isolation of the pathogens.

Treatment:

So, following are the treatment we followed which were given below;

·      The Na/K iodide through per orally or the IV which reduce the fibrous tissue reaction

·      In cattle K-iodide 6-10 gram per day for seven to ten days

·      Na-iodide 70g per day one dose in both cattle and sheep

·      Na iodide may lead to abortion.

·      Dyspnea and the tachycardia

·      S/C injection is a standard route for Na iodide in the sheep

·      And last, we use the broad-spectrum antibiotics.

Control:

As we also know that the control is one of the most important part to prevent the disease so in control we must do the vaccinations on time and must give the fresh and clean food to the animal and make sure that there is no hard or any material that will give damage to the animal should be removed from the food of the animal.
