Do cockroaches carry scabies, and how many pathogenic bacteria can cockroaches carry?

*Cockroaches carry no scabies**. Cockroaches carry the eggs of disease-causing bacteria, viruses, protozoa, fungi and parasitic worms, and can serve as intermediate hosts for many types of worms. Cockroaches have been shown to carry about 40 species of bacteria that cause disease in vertebrates, the important ones such as Mycobacterium leprae for leprosy, Murine bacillus for bubonic plague, Shigella dysentery for dysentery and Shigella paradysentery for pediatric diarrhea, Staphylococcus aureus for boils, Pseudomonas aeruginosa for urinary tract infections, Escherichia coli for genitourinary tract and intestinal infections, and a variety of Salmonella bacteria that transmit enteric diseases and gastritis, such as Salmonella typhu, Salmonella typhi, etc.

Cockroaches have been shown to carry 40-50 kinds of pathogens, such as dysentery bacilli, E. coli, etc., which can cause food poisoning and spread hepatitis, pneumonia and other pathogenic bacteria.

Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households.

Like the dark and afraid of light, day and night, this is also an important habit of cockroaches.

At night, especially after the lights are turned off and people go to sleep, they go out to do activities, or forage for food, or seek a mate.

CockroachesThere is a vice of eating, spitting, excreting, and secreting a smelly liquid, in its activity, not onlyIt can carry more than 40 pathogens such as Mycobacterium leprae, Yersinia pestis, and Shigella dysenteryIt is also an important vector for the transmission of intestinal diseases and parasitic diseases, and its secretions and feces contain a variety of carcinogens.

Cockroaches often hide in dark corners such as kitchens and bathrooms, which are not easy for people to notice, not only endangering storage items such as grain, oil, food, clothing and books, but also spreading diseases and causing harm to people.

Methods of cockroach control

To control cockroaches, it is necessary to pay attention not to use cockroach bait of the same composition for a long time to prevent them from developing resistance. It is best to use physical methods such as sticky cockroach boards in conjunction with medications.

In addition, it is necessary to pay attention to environmental remediation, manage food and garbage well, garbage should be cleaned every day, and food should not be left in the open air. Don't pile up too much clutter in the kitchen to reduce cockroach habitat. Gaps or holes in the home should be sealed with cement.

In addition, it should be noted that sometimes after the cockroach is slapped to death, the egg sheath is not damaged, and the baby cockroach will still hatch. Therefore, it is necessary to burn to death, scald to death with boiling water or trample to death after manual cleaning, or wait for the next batch of small cockroaches to hatch and apply pesticides again to completely kill them.

According to investigations, a variety of pathogenic bacteria were transmitted, such as Yersinia pestis, dysentery bacillus, Escherichia coli, Aspergillus flavus, enterovirus, poliovirus, roundworm eggs, pinworm eggs, etc. Cockroach excrement, vomit, can cause human allergic reactions, asthma or allergic dermatitis, rhinitis, aspergillus flavus, hepatitis, pneumonia, tuberculosis, intestinal disease and other more than 40 kinds of pathogenic bacteria, and cause food poisoning, cockroaches are the cause of a variety of diseases.

Transmission of bacteria and parasite eggs: Cockroaches can carry more than 40 pathogenic bacteria, such as Yersinia pestis, Mycobacterium leprae, dysentery bacillus, Pseudomonas aeruginosa, Escherichia coli and Salmonella that can cause intestinal and gastritis.

In addition, cockroaches can carry a variety of pathogenic bacteria that cause food poisoning. Cockroaches can also carry roundworm eggs, duodenal hook nematode eggs, whipworm eggs, pinworm eggs, worm eggs, etc.

Molds: A variety of molds have been detected from cockroaches, such as Penicillium, Mucor, Aspergillus flavus, yeast, Trichoderma, Rhizopus and other 12 species.

Viruses: Experimental studies have confirmed that cockroaches can carry, maintain and excrete viruses, including: enterovirus, poliovirus, etc.

Allergic reactions: The secretions, excretions, vomit in the cockroach's body, the bacteria carried on the body surface of the cockroach, the parasite eggs and the powder after the cockroach carcass is dried, and the person will have an allergic reaction after contact.

Dangers of Cockroaches Spreading Diseases Cockroaches are vectors of a variety of diseases, often inhabiting all kinds of human living and living places, going to and from garbage heaps, gutters and toilets and other filthy places, bringing serious hygiene and health problems. Its body surface and internal intestines can carry more than 40 kinds of pathogenic bacteria, molds, viruses and parasite eggs. A single cockroach can isolate tens of thousands of bacteria from its antennae, feet, and digestive tract.

Therefore, cockroach control is an important part of nosocomial infection. Cockroaches were detected by pathogen detection, and pathogens such as hepatitis B, hepatitis A virus, Pseudomonas aeruginosa, Proteus, Salmonella, dysentery bacillus, and roundworm eggs were isolated.

The Oriental cockroach (Blatta orientalis, i.e., the Oriental cockroach) is considered the dirtiest household pest. The body is ovate, black or dark brown, shiny, and 25 to 30 mm long. The life history resembles that of the American cockroach, the males have short, well-developed wings, while the females have vestigial wings.

Native to Asia, it was later distributed to all temperate regions with merchants' means of transportation.

Cockroaches can be artificially infected with bacteria that cause diseases such as cholera, pneumonia, diphtheria, melioidosis, anthrax and tuberculosis in Asia. Cockroaches can carry a variety of worm eggs such as roundworms, duodactyl bridges, hookworms, beef tapeworms, windworms, whipworms, etc. They can also serve as intermediate hosts for a variety of nematodes, such as Candida candida, Hymenola brevis, and tumor tubes.

Cockroaches can also carry a variety of protozoa, of which 4 species are pathogenic to humans or animals, such as dysentery Amima, Giardia enterus, etc. Experimental studies have confirmed that cockroaches can carry, maintain and excrete viruses, including coxsackievirus, poliovirus, etc. Cockroaches can also carry fungi.

In Nanjing, Jiangsu Province, and Nantong, a variety of fungi have also been isolated from cockroaches caught indoors, including a large number of Aspergillus flavosalis. Although cockroaches carry a variety of pathogens, it is generally believed that pathogens cannot multiply in their bodies and are mechanically transmitted.

However, due to their wide range of aggression and miscellaneous food habits, they can not only move in garbage, toilets, washrooms and other places, but also can eat on food, so they cause intestinal diseases and the spread of parasite eggs cannot be ignored.

In addition, there have been reports of allergies caused by cockroach body fluids and feces. In addition, factory products, store goods, and home food can all cause economic losses due to cockroach bites and fouling. Occasionally, there are accidents caused by cockroach infestation that leads to malfunction of communication equipment and computers.

Some people abroad call cockroaches "computer pests".

Cockroaches harboring viruses carry at least 40 kinds of bacteria, nearly 10 kinds of viruses, 7 kinds of parasite eggs and 12 species of molds, according to the survey, the detection rate of aspergillus flavus on cockroaches is 29-50%, which are all teratogenic and carcinogenic substances. Cockroaches are omnivorous insects. It loves the food that humans eat; I also love books, leather, clothes, soap, etc.; They also often climb into gutters, garbage heaps, toilets and other places to eat feces, dead animals, and other decaying organic matter, and eat everything.

1. Cockroaches are the oldest insects 350 million years ago, cockroaches have been active on the earth, and they are the oldest insect population in the world that has successfully multiplied so far. Paleontologists have found hundreds of species of cockroach fossils in the Carboniferous strata. It's amazing how many cockroaches were the same as what you see in the kitchen today.

2. How much do you know about cockroaches in the world In 1969, it was estimated that there were more than 4,000 species of cockroaches in the world, and in 1982 there were more than 5,000 species. There were 52 species recorded in China at the earliest, and now there are as many as 200 species. But the vast majority of cockroaches live in the wild, and there are only more than 10 species that are closely related to humans.

3. Cockroaches carry at least 40 kinds of bacteria, nearly 10 kinds of viruses, 7 kinds of parasite eggs and 12 kinds of molds, according to the survey, the detection rate of Aspergillus flavus carried by cockroaches is 29-50%, which are teratogenic and carcinogenic substances.

4. Several methods of cockroach extermination are now commonly used and effective methods include putting cockroach poison erbium, spraying insecticides, smearing cockroach chalk, sprinkling powder, and applying insecticidal smoke, etc., according to the actual situation, choose to use. In addition to the method of killing pests with chemical drugs, cockroach extermination can also be trapped, such as sticky trapping boxes and trapping bottles.

5. The nemesis of cockroaches has recently been approved for the market in the United States by a new compound called hydrogenated juvenile hormone. Spraying in a 100-unit apartment in Florida showed a 95 percent reduction in cockroach density over eight months, and a 100 percent kill rate in a closed kitchen. This drug can deform the pest's wings, behave abnormally, and eventually lose its ability to reproduce.

Doing no evil, eating everything, and crawling on the food where cockroaches crawl everywhere will leave a disgusting odor; often chews people's beloved clothes; Accidents that injure people, such as cockroach bites and burrows into the ears, occur from time to time.
