Threadworm (Enterobius vermicularis).

1. Female ( slides, a magnifying glass). 1. Female ( slides, a magnifying glass).

body dimensions - 10-12 mm. fusiform body. The rear end of the body greatly sharpened. A distinctive feature of the structure is the presence of

spherical expansion of the esophagus - esophageal bulb. Most of the body is busy pinworms tubular reproductive system filled with eggs. In the rear

part of the body visible intestine, ending the anus.

2. Male ( slides, a magnifying glass). 2. Male ( slides, a magnifying glass).

body dimensions - 3-5 mm. The rear end of the body is twisted spirally. In front of the body, as well as in females, visible through the

translucent bulb covers esophagus.

Whipworm (Trichocephalus trichiurus).

1. Female ( slides, a magnifying glass). 1. Female ( slides, a magnifying glass).

body dimensions - 35-50 mm. The front end of the body greatly elongated Trichomanes (hence the name of the helminth), the rear end - a straight line.

In the front end of the body has the esophagus, in the back, the extended end of the body - the remaining sections of the intestine and organs of the reproductive system.

2. Male ( slides, a magnifying glass). 2. Male ( slides, a magnifying glass).

body dimensions - 30-40 mm. Unlike females rear end of the male body is twisted spirally on the dorsal side.

Whipworm eggs.

Light microscopy. Dimensions: 50-54 x 22-33 mm. Bochonkovidnaya form, with light "cork" on the poles. Almost colorless, with a grayish granular

contents inside. Egg shell is thick, multi-layered.

1. Ascaris human (Ascaris lumbricoides), ( cross-section of the female slides). The cut has a rounded shape. The wall of the body (skin and 1. Ascaris human (Ascaris lumbricoides), ( cross-section of the female slides). The cut has a rounded shape. The wall of the body (skin and

muscle) bag consists of thick cuticle, a thin layer of hypodermis and the longitudinal muscle layer. Four hypoderm forming roller, protrude into the

body cavity, two lateral trapezoid shape (in which the channels lie excretory systems), as well as dorsal and ventral rollers triangular shape (in which

visible light sections of nerve trunks). Towards the dorsal and ventral hypodermis stretch rollers protoplasmic outgrowths muscles. The body cavity

roundworm visible slice sleeping intestine (its wall is formed by columnar epithelium) and multiple tubular sections of the pair of female reproductive

system rounded shape and different diameters. The largest of them with thick walls - sections queens, filled with brightly colored eggs mature.

x 40-50 mm. Form oblong-oval, asymmetrical (one side is more convex,

the other - is flattened). Egg colorless. Shell eggs druhkonturnaya

transparent.

Krivogolovka duodenum (Ankylostoma duodenale).

1. Male. The body size of 8-11 mm. At the front, a bent end of the body is visible worm cuticular oral capsule with teeth. The rear end of the body 1. Male. The body size of 8-11 mm. At the front, a bent end of the body is visible worm cuticular oral capsule with teeth. The rear end of the body

is extended in the form of an umbrella - it copulatrix (copulatory) bag.

Female. The body size of 10-13 mm. At the front end of the body is oral capsule with cuticular teeth. The rear end of the tapered body of the female. Female. The body size of 10-13 mm. At the front end of the body is oral capsule with cuticular teeth. The rear end of the tapered body of the female.

Most of the body is filled with helminth organs of the reproductive system.

Guinea worm (Dracunculus medinensis).

isolated from the larvae inside the host environment. As a result, most of the larvae in the calcified capsules dies.

Microfilariae.

Microfilariae in the blood smear. Light microscopy (high (1) and small (2) increase). Microfilariae in the blood smear. Light microscopy (high (1) and small (2) increase).

Against the backdrop of blood cells - red blood cells and white blood cells - visible worm-like curved filarial larvae. Each of them is covered with shaped

case, the size substantially larger than the larva itself, and therefore it is peeled from the surface of the body.
