Roundworms are a kind of biohazard organism harmful to humans and other living organisms. Roundworms can’t be seen with naked eyes because they are microscopic. There are various types of roundworms that possess serene threats to the health of humans. Some of which are filaria, rishta, whipworm and diseases they tend to cause include diarrhea, fever, etc. There are a total of 20,000 species of roundworms inhabiting our planet.
Now, how they are named so is because their bodies possess round transverse incisions. They can be found everywhere from deep inside the soil to land. Roundworms are further classified into many types that link them to several other categories of organisms. So, the first classification criteria are whether they are parasitic or free-living. Most roundworms just live at the expense of other representative organisms.
Appearance Of Roundworms
Roundworms aren’t very evolved or modified organisms, so their body is quite simple and lack proper or separate systems for different functions. Scroll below to know their anatomy.
- The roundworms are indeed very small in size, being microscopic.
- They can attain up to a length of 8m.
- Their body structure follows bilateral symmetry.
- Their body is usually shaped like a spindle.
- They lack any kind of segmentation.
- Sexual dimorphism is present.
- The actual excretory organs are absent, so they use their cavity fluids for the excretion of harmful and indigestible substances.
- This primary body cavity can be termed as pseudo goals.
- They have phagocytic cells in the excretory system.
- No circulatory or transportation system is there.
- They have their muscular system as only a longitudinal group of muscles.
- The respiratory system is absent.
- Their nervous system looks like muscle rollers.
- They have a reproductive and digestive system inside.
- Their digestive tube has three diverse parts, anterior, middle, and hindgut.
- Their anus is quite visible.
Roundworm’s Life Cycle
Now, the life cycle varies with the varying type of roundworms. If it is free-living, then it resides in the sea or ocean bottom. Those living in soil and freshwater also remain at the bottom. Those who belong to the parasitic category reside in decomposing residues of plants, plankton, and other animals. They also live in other roundworms. In fact, they settle up in human bodies and rule over different internal systems, like the brain, blood vessels, heart, eyes, intestines, lungs, stomach, and all the remaining others. Roundworms are able to crawl on soil and swim in or underwater.
Do you know that the smallest roundworm is called rotifer? The size it attains in its life cycle is 2mm. It is also the smallest multicellular animal.
Type Of Reproduction In Roundworms
The organisms of this species are usually dioecious, along with being hermaphrodites. Their reproductive system resembles some tubular structure. They possess sexual dimorphism, so there are visible variations in their males and females. Let’s examine it differently for both male and female roundworms.
- Males possess a single unpaired tube.
- They are prolific.
- Females have two unpaired tubes.
- They are also very fertile.
- A single female has a tendency to lay 200,000 eggs in a day.
Conditions Required For Larvae’s Maturation
- The parasite can only develop inside upon entering the human body.
- A temperature of 20-25 degrees is required.
- A humid environment is required.
- The maturation process takes around 2-3 weeks.
Process Of Egg Development
Roundworms can also give live birth. The eggs of their larvae are covered with a lean shell covering.
If the egg development occurs externally in aerobic conditions, then it takes 21 days. After that, eggs become harmful and potentially capable of causing a parasitic infection. This is how the larva is formed.
If it occurs inside a human intestine, then the larva emerging from the shell is introduced into its walls and then enters the blood capillaries. Blood flow makes the larva enter the liver, then into the lungs. It reaches the oral cavity passing through the respiratory tract from here. Next, it enters the intestine after getting mixed with saliva in the mouth. Then there, it attains puberty.
The roundworm breeding cycle doesn’t involve any change of hosts, unlike flat parasites that have two different hosts- immediate and main. Also, they require oxygen to develop their larvae.
Roundworms Are What Type Of Biohazard
Roundworms are very infectious to human health. These mainly include filaria, whipworm, rishta, etc. They hamper and damage their host’s body organs. The parasitic category roundworms cause massive harm to human health, poison their tract, and hamper digestive functioning. Some common examples of reversion to roundworms are what type of biohazard include:
- Vladislav resides in the large intestine. The length of their body reaches up to 5.5 cm. They are gray in color and have a tail as an identification mark. The females own an arc-shaped tail, whereas it is spiral-shaped in the case of males. These worms feed human blood. Mostly, these make human men their host.
- Rishta resides in dirty and filthy water. So, if one consumes unpurified water, then they have the potential of inviting it into their body. From there, they reach subcutaneous tissue. They secretly create holes in the skin to remove their larvae from the host’s body. Such parts of their host man get inflamed.
- Trichinella is another dangerous parasite for humans. The females are about 3mm in size, and the males are approx. two times smaller than that. Their larvae enter the human body via meat consumption. The larvae reach muscle following the blood flow. Here, they are covered with a calcareous capsule that helps them remain the same for several years. They target rats to make their hosts. Pigs feed on decayed rats, and then these pigs can infect humans later on.
- There are many other ways to by which one can get infected with roundworms, as-
- Consuming raw and poorly washed vegetables, fruits, pulses, etc.
- Even flies in the ambiance can act as a medium for transferring roundworms.
- Dirty hands and unhygienic practices can contribute to the ingestion of roundworm eggs in the body.
- Drinking dirty water.
How To Be Safe Against Roundworm Infections
It’s important to ensure proper hygiene for your body and in your environment. Develop healthy eating habits. Drink purified water. Now, you know the different passages by which such infectious roundworms can reach you, so ensure you take care of all those.
- Wash your hands before and after taking your meals
- Sprinkle and wash vegetables with boiling water before cooking. Hot water tends to kill such parasites.
- Always cover the leftover food as open food attracts such worms.
- Usage of aerosols and adhesive tapes is needed to prevent the existence of these harmful bugs.
There is a diverse range of organisms on this planet. Some were giant as dinosaurs to be several feet tall, whereas some are too small to be seen with naked eyes like bacteria. So, for their easy and enhanced diagnosis and analysis, they have been divided into different categories. Roundworm is one such category. They are multicellular, so they are definitely not as simple as bacteria. But their bodies are microscopic in size, so they aren’t even as complex as huge animals and humans.
The main question which arises is that roundworms are what type of hazard. There are various categories of roundworms. Mainly parasitic and free living. The parasitic ones are a biohazard to human health. They need some host to reproduce and develop their larvae. But, for their hosts, they hamper the body parts and functioning of humans and other animals. This is because they cause so many diseases like infections, fever, diarrhea, indigestion, and whatnot. Even if they make hosts in other animals, still the chances of spreading infections among humans are high.
For this, one must be very careful about their hygiene and healthy habits. Wash hands in certain intervals of time. Eat well-cleansed vegetables and fruits. Avoid water stagnation after rain. Avoid consuming filthy water. Healthy habits and a hygienic environment are what can save you.
The main concern is that considering the anatomy of roundworms, they possess sexual dimorphism. And if you see the females of their species, they are very prolific and can lay up to 200,000 eggs in a day, so they require multiple hosts too in short intervals of time. In fact, their egg development consumes a maximum of 21 days. So, this fertility factor also possesses a high infection rate they tend to cause.
So, maintaining proper conditions and taking care of all the essentials needed to get rid of them is what can help you fight off the infections they cause. If you get caught by them once, your body will suffer and will need time to recover. You will become weak physically and stressed mentally because of not being able to focus on your work. Obviously, the medicines and treatment for such infections can burn a hole in the pocket.
