Parasitical Worms.com Dog hookworm disease is collectively known as subcutaneous larva syndrome or typhus. Two commonly mentioned agents are Ancylostoma caninum and A.Braziliensis.
It may also be caused by other species of the Ancylostoma genus such as A

.ceylanicum .. The permanent hosts of these worms are dogs, cats, wolves, foxes, raccoons, hyenas ..

Human hookworm disease is classified as a parasitic animal disease. And up to now, although the number of clinical cases is increasing, this pathology has not been studied much.
1. Shape of hookworm disease in humans
Adult ancylostoma caninum is about 14mm long and 0.6mm across The smaller male is 10mm long and 04mm across. Adult worms have a wide mouth with three characteristic sharp teeth. Eggs like human hookworm eggs are smaller than average 64 x 40 µm.

. The cycle of development of hookworm disease in humans
Eggs are discharged in the feces of dogs and cats. 24 - 48 hours later, the larvae will hatch 1, under normal conditions of temperature and environment will develop to stage 2 or phase 3 (with tubular esophagus).
In addition to the infectious larvae environment capable of surviving more than a week, when the dog or the host permanently exposed the larvae, the larvae will penetrate hair follicles and penetrate into the bloodstream.
Dogs can also be infected by swallowing larvae After entering the bloodstream, the larvae also move to the lungs and enter the alveoli and return to the intestine similar to the cycle of human hookworms.
From the time it enters the dog's body until the adult worm's intestinal cavity takes about a week. Adult worms can live for about 6 months, averaging about 28,000 eggs a day and the process of laying about 2 months.
When people accidentally come into contact with contaminated soil by risky behaviors such as not wearing protective gloves when working in contact with soil, barefoot, children playing with soil, shooting bi balls, etc. skin and will penetrate hair follicles into the connective tissue beneath the skin.
Because the larval collagenase cannot digest the human venous wall, the larvae do not enter the bloodstream and return to the lungs, from which the larvae move into the subcutaneous layer, causing the larvae to move under the skin.

3. Epidemiological characteristics of hookworm disease in humans
The disease is found all over the world, much in the Northern Hemisphere The disease is mainly found in tropical regions and where people have a habit of barefoot or direct contact with the soil. In 1974, Saito discovered a 35% infection rate in dogs.
4. Symptoms of hookworm disease in humans
There are two types of diseases caused by cat and dog hookworms: the larvae that travel under the skin (CLM) and eosinophilic enteritis (EE).

4.1 Larva syndrome moves under the skin
Several hours after the larva invades, the lesion forms a red nodule. When the larvae start moving, a tunnel will appear. Surrounding tissue may be inflamed.



The larvae will move a few millimeters per day, the old location of the tunnel will be dry and itchy.
The larvae can be moved by secreting the protease enzymes (metaprotease with a molecular weight of 68kda, a protease enzyme of 38kda) and hyaluronidase, which destroy the connective tissue under the skin along the path of the larva. coincide.
Some small water bubbles may appear along the tunnel, impregnated with eosinophils. Secondary secondary infections may sometimes occur.
The most common lesions are areas that are in contact with the soil, such as hands, feet, forearms, and legs, sometimes in the abdomen when the patient has a habit of holding agricultural products in front of the abdomen, ..
42. Eosin-stained enteritis with eosinophils
Inflammatory reactions are seen in the small intestine, colon, cecum and appendix.



. Inflammatory phenomena and inflammatory secretions along with eosinophil invasion. The larvae are found and surrounded by eosinophils.
The main symptom is abdominal pain, located along the colon frame, which tends to deviate from the right towards the colon. Usually disappears after 1 month, sometimes anorexia, nausea and diarrhea. Some patients with hypersensitivity may experience acute appendicitis or intestinal obstruction. Rarely, there is a chance that larvae may migrate together
The majority of cases in patients are usually mild, self-limiting or asymptomatic despite ulcerative intestinal sores. The pathological immune system in eosinophilic colitis is still unknown. Everything refers to the general defense mechanism of the infection caused by helminths although there have been many findings about the enzyme system produced by adult worms when parasitic in the intestines (fibrin explanation, anticoagulant, inhibition 1Xa.cysteine protease, protease, inhibits neutrophil function).



.
5. Diagnosis of hookworm disease in humans
Most important is based on the specific clinical and epidemiological factors.
A diagnostic serum with secretory antigens can be used to find specific antibodies (ELISA) in 85% of eosinophilic enteritis.
6 Treatment of hookworm disease in humans
Thiabendazole, Albendazole, antibiotics, anti-inflammatory, topical cream as needed
7. Prevention of hookworm disease in humans
Use labor protection equipment when.
