Ascaris is a type of parasitic worm that can infect humans and animals. Male Ascaris worms are typically smaller and thinner than female worms, and they have a slightly curved shape. They can be found in the small intestine of their host, where they feed on partially digested food.

Male Ascaris worms are primarily responsible for the reproduction of the species. They have a specialized reproductive system that includes testes and a copulatory bursa, which is a structure used for fertilizing the female worms. Male Ascaris worms have a small opening on their underside, called the cloaca, which is used for both excretion and reproduction. During mating, the male worm uses its cloaca to transfer sperm to the female worm's genital opening, called the vulva.

One of the main characteristics of male Ascaris worms is their size. As mentioned earlier, male worms are typically smaller and thinner than female worms. This is because the female worms have a larger and more developed reproductive system, which requires more energy and resources to maintain. Male worms are also more numerous than female worms in an infected host, as females typically produce thousands of eggs each day, while males do not.

Another characteristic of male Ascaris worms is their ability to move. Unlike female worms, which are often found stationary in the intestine, male worms are more mobile and are able to swim through the intestinal contents. This is due to their thin and elongated shape, which allows them to move more easily through the intestine.

Male Ascaris worms can cause a variety of health problems in humans and animals. In humans, they can cause abdominal pain, nausea, and diarrhea. They can also block the intestine and cause serious complications, such as perforation or obstruction. In animals, Ascaris worms can cause weight loss, reduced appetite, and diarrhea.

Overall, male Ascaris worms are an important part of the parasitic life cycle of this organism. They play a crucial role in the reproduction of the species and can cause a variety of health problems in humans and animals. It is important to take steps to prevent Ascaris infections, such as washing hands thoroughly after using the bathroom and cooking meat to proper temperatures, in order to reduce the risk of infection.

The post-anal portion in the male is sharply curved downwards while in the female it is nearly straight. The two canals unite with each other at the anterior end and open to the outside through the single excretory aperture situated on the ventral side. Once they're back in the intestines, the parasites grow into male or female worms. It gradually tapers at both ends. This layer has three strata.

ADVERTISEMENTS: The dorsal and ventral longi┬ştudinal nerves are connected with each other by transverse commissures. One of the most common worm infections in people worldwide, ascariasis is uncommon in the United States. People can accidentally ingest swallow contaminated soil through hand-to-mouth contact or by eating uncooked fruits or vegetables that have been grown in contaminated soil. In lungs the juveniles make their way out from the blood capillaries into the alveoli. Expert Review of Anti-infective Therapy. Then, in another 3or 4 days, these reach into the lungs via the hepatic veins, heart and pulmonary arteries. Xavier; Arolas, Joan L.

Difference Between Male and Female Ascaris

In such organs, these soon become dead and encysted in calcified cysts. These spicules can protrude out and get retracted through the cloacal aperture by special protractor and retractor muscles. The tiny microscopic ascariasis eggs can't become infective without coming into contact with soil. This peculiar appearance is due to the differentiation of the cell into a contractile and a nuclear part. This structure is differentiated at the anterior region as the testis, the middle region as the vas defe┬şrens and the posterior region as the seminal vesicle. The cuticle is permeable to salts, water and the products of metabolism.

Summary ÔÇö Male vs Female Ascaris Ascaris is a genus of roundworms. The body of these worms is covered by cuticle, which has minute striations which imparts a pseudo segmented appearance to the worms. Fertilized eggs pass one-by-one into the uteri. One of the lips is situated mid-dorsally and the remaining two are situated sub-ventrally. Infection occurs when a human swallows water or food contaminated with embryonated eggs.

Vagina: The uteri open into short and relatively narrow vagina. Female worms are larger than the males and are further distinguished by the presence of separate and independent genital aperture situated on the ventral surface at about one-third of the body length from the anterior Fig. Moreover, they are cylindrical in shape. However, they both have reproductive organs since they reproduce through sexual reproduction. Male Ascaris is a short and thin worm while female Ascaris is a long and wide worm.

In quite early stages, different blastomeres of the embryo become earmarked to form different organs of future juvenile ascaris. It is milk-white in colour but presents a reddish-yellow shade when alive. Posterior end:Sexual dimorphism is clearly visible at the posterior end of these roundworms. A little up on the ventral side of the posterior end is situated the anus which is transverse in position and in males it serves also as the reproductive aperture.

They are mostly concentrated in China, Philippines, India, Korea and the Pacific Islands. In addition, they contain a CONTENTS 1. Boring through the intestinal wall, these juveniles make their way into the sub-mucosal blood capillaries. The wall of vagina is quite muscular and contractile. Wash fresh fruits and vegetables thoroughly. The sperms are amoeboid whereas the ova are elliptical in shape. In females, just before the tail ending, anus is present.

It is presumed that the canal is an intracellular tubular extension of a single enormously elongated cell. These structures are present near the posterior opening. Here it grows and gets differentiated into amoeboid gametocytes. Eggs containing the second stage juvenile are called embryonated eggs. ADVERTISEMENTS: In this article we will discuss about:- 1.
