Bacterium Borrelia Anserina

Espiroquetosis en aves: Spirochaeta gallinarum.

Septicemia espiroquetosis it is a disease transmitted by the bites of mites and insects. The germ causing is Borrelia anserina, also called. Spirochaeta gallinarum.

Birds affected by espiroquetosis show deeply downs, being able to move towards a state caquéctico accented or succumb to one or two days in access of fever.

The exceedance of the acute crisis in the bird determines immunity for about six months.

Borrelia. It is a genus of spiral-shaped, Gram-negative bacteria belonging to the spirochete class that grows in synthetic and enriched media. It is a microaerophilic microorganism. It infects both humans and animals.

Because so little is known about this pathogen, there isn't much to say, but there are some implications for veterinary medicine, particularly in birds.

Tick, Borrelia anserina

Tick larvae, Borrelia anserina

Routes of transmission:

An infected tick can transmit Lyme disease to humans and animals through their bite.

The risk of becoming ill varies by region, and after a tick bite, this risk is actually quite low.

Only those ticks that remain in the body for more than 12 hours to transmit the disease.

The risk is greater after 48 to 72 hours after contact with the tick.

Often, the tick remains in the body without the person realizing, and many are infected without having noticed bite one.

Because bacteria multiply very slowly, the lyme disease develops perniciosamente in several phases. The evolutionary course is benign.

Symptoms:

A typical symptom that manifests itself shortly after the infection is a stain of red in the area of the bite, the darker at the edges and the size of the palm of the hand; it is the so-called erythema chronic migration (ECM).

Over the course of weeks, months, or years, other organs may become involved (joints, nerves, meninges, heart, eyes, skin): a multi-system inflammatory disease; that is, it affects the skin and spreads to the joints and the nervous system, and may affect other organs in its most advanced stage.

If diagnosed and treated with antibiotics in its early stages, Lyme disease is almost always curable; otherwise, the likelihood of a cure depends on how each individual’s body responds to treatment.

Typical symptoms of this stage are:

  • Erupción roja y circular a lo largo de la picadura.
  • Fever and chills.
  • Fatigue.
  • Muscle pain of joints.
  • Headache.
  • Swollen glands.
  • Enlargement of lymph nodes.

Types of Borrelia that affect animals:

Within the Borrelia genus, the species that can infect animals is Borrelia anserina, which directly affects birds; its spirochetes primarily affect chickens. This type of Borrelia has also been detected in ducks, turkeys, and geese.

In birds, avian spirochetosis is caused and transmitted by ticks; it is also transmitted by other vectors such as mosquitoes and mites. This disease is characterized by acute septicemia, which can lead to high mortality rates in chickens within three or four days.
