Infectious and parasitic diseases

Scabies

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

Pediculosis (lice)

Pediculosis is a parasitic anthroponosis with a contact mechanism of pathogen transmission, the main symptom of which is skin itching. A synonym for the disease is lice infestation.

Toxocarosis - Treatment and Prevention

There is no single etiotropic treatment for toxocariasis. Antinematode drugs are used: albendazole, mebendazole, diethylcarbamazine. All of the listed antihelminthic drugs are effective against migrating larvae and are not effective enough against tissue forms located in granulomas of internal organs.

Toxocarosis - Diagnosis

Diagnosis of toxocariasis is based on the epidemiological anamnesis and clinical symptoms. The presence of persistent long-term eosinophilia is taken into account, although it is not always found in ocular toxocariasis. An indication of keeping a dog in the family or close contact with dogs, geophagy indicates a relatively high risk of contracting toxocariasis.

Toxocarosis - Symptoms.

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

Toxocarosis - Causes and Pathogenesis

The causative agent of toxocariasis (canine roundworm) belongs to the type Nemathelminthes, class Nematodes, suborder Ascaridata, genus Toxocara. T. canis is a dioecious nematode, sexually mature individuals of which reach relatively large sizes (the length of the female is 9-18 cm, the male - 5-10 cm). Toxocara eggs are spherical, 65-75 microns in size. T. canis parasitizes dogs and other representatives of the canine family.

Toxocarosis - Overview

Toxocariasis (Latin: toxocarosis) is a chronic tissue helminthiasis caused by the migration of larvae of the dog helminth Toxocara canis in the human body. It is characterized by a recurrent course with damage to internal organs and eyes.

Trichinosis - Treatment and Prevention

Treatment of patients with moderate and severe forms of trichinellosis is carried out in an infectious hospital or a 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 examine food remains (meat or meat products) for the presence of trichinella larvae. Difficulties arise in diagnosing sporadic cases of trichinellosis. In such situations, the epidemiological anamnesis is of great importance.

Trichinosis - Symptoms

The incubation period for trichinellosis lasts on average 10-25 days, but can range from 5-8 days to 6 weeks. When infected in synanthropic foci (after eating infected meat from domestic pigs), there is an inverse relationship between the duration of the incubation period and the severity of the disease: the shorter the incubation period, the more severe the clinical course, and vice versa. When infected in natural foci, such a pattern is usually not observed.
