Infectious and parasitic diseases

Scabies

Scabies - anthroponous tick disease, affecting the stratum corneum of the epidermis, with the contact mechanism of transmission of the pathogen. The causative agent of scabies is a parasitic itch mite Sarcoptes scabiei hominis.

Pediculosis (lice)

Pediculosis is a parasitic anthroponotic disease with a contact mechanism for the transmission of the pathogen, the main symptom of which is pruritus. A synonym for the disease is lice.

Toxocariasis: treatment and prevention

Etiotropic treatment of toxocarosis does not have a single scheme. Apply antinematode drugs: albendazole, mebendazole, diethylcarbamazine. All these anthelmintic drugs are effective against migratory larvae and are not effective against tissue forms found in granulomas of internal organs.

Toxocariasis: diagnosis

Diagnosis of toxocarias is based on epidemiological history, clinical symptoms. Consider the presence of persistent long-term eosinophilia, although with eye toxocariasis it is not always found. Indication of the maintenance in the family of a dog or on close contact with dogs, on geophagy indicates a relatively high risk of infection by toxocarosis.

Toxocariasis: symptoms

Symptoms of toxocarias are the main criterion for dividing this disease into: toxocarias manifest and asymptomatic, and in the course of the course - acute and chronic.

Toxocariasis: causes and pathogenesis

The causative agent of toxocarosis (ascarid dog) is of the type Nemathelminthes, the class Nematodes, the suborder Ascaridata, the genus Toxocara. T. Canis - dioecious nematodes, sexually mature specimens of which reach relatively large sizes (female length 9-18 cm, male 5-10 cm). Eggs of Toksokara are spherical in shape, 65-75 microns in size. T. Canis parasitizes in dogs and other representatives of the canine family.

Toxocariasis: an overview

Toxocarosis (Latin toxocarosis) is a chronic tissue helminthiasis caused by the migration of the helminth larva of Toxocara canis in the human body. It is characterized by a recurrent course with internal organs and eyes.

Trichinosis - Treatment and Prevention

Treatment of patients with moderate and severe form of trichinosis is carried out in the conditions of an infectious inpatient hospital or general medical institution. Treatment is largely individual and includes specific (etiotropic) and pathogenetic therapy.

Trichinosis - Diagnosis

It is necessary to establish a common source of infection and, if possible, to conduct a study of food residues (meat or meat products) for the presence of Trichinella larvae. Difficulties arise in the diagnosis of sporadic cases of trichinosis. In such situations, a significant epidemiological history.

Trichinosis - Symptoms

The incubation period for trichinosis on average lasts 10-25 days, but can range from 5-8 days to 6 weeks. When infected in synanthropic foci (after consuming infected meat from domestic pigs), there is an inverse relationship between the duration of the incubation period and the severity of the course of the disease: the shorter the incubation period, the harder the clinical course, and vice versa. When infecting in natural foci, such patterns are usually not noted.
