Leptospirosis

Also known as Weil’s Disease, Mud fever, Canicola fever, Flood fever, Swineherd’s Disease, Japanese Seven Days fever.

Definition and Background

* A bacterial zoonotic disease caused by spirochaetes of the genus Leptospira that affects humans and a wide range of animals, including mammals, birds, amphibians, and reptiles.

* First described by Adolf Weil in 1886 when he reported an “acute infectious disease with enlargement of spleen, jaundice and nephritis”

Causative Agent

Leptospira - genus bacteria was isolated in 1907 from post mortem renal tissue slice.

Commonly found: Leptospira pyrogenes, Leptospira manilae, & other species like L. leterohemorrhagiae, L. canicola, L. batavia, L. Pomona, L. javinica

Predisposing Factors

Direct exposre to the microorganism is the method in which the disease is contracted.

* Occupational exposure: farmers, abattoir workers, trappers, veterinarians, loggers, sewer workers, rice field workers, and military personnel.

* Recreational activities: fresh water swimming, canoeing, kayaking, and mountain biking in warm areas.

* Household exposure: pet dogs, domesticated live stock, rainwater catchment systems, and infestation by infected rodents.

Source of Infection

Infection comes from contaminated food and water, and infected wild life and domestic animals especially rodents.

1. Rats ( L. leterohemorrhagiae) are the source of Weil’s disease frequently observed among miners, sewer, and abattoir workers.

2. Dogs (L. canicola) can also be the source of infection among veterinarians, breeders, and owners of dogs.

3. Mice (L. grippotyphosa) may alos be a source of infection that attacks farmers and flax workers.

4. Rats (L. bataviae) are the source of infection that attacks rice field workers.

Modes of Transmission

* Wild mammals seem to serve as the primary reservoir of most leptospiral serovars. The organism has been found in

    Zoonotic Disease

    • 122 Words
    • 1 Page

    CL is typically transmitted when subcutaneous abscesses are ruptured. Bacteria from ruptured abscesses are released into the environment, allowing transmission to susceptible hosts. When an abscess ruptures, it can contaminate pens, water buckets, barns, shearing clippers and feed bunks. The pus contains a high number of bacteria, and these bacteria can survive for several months in the environment. When susceptible animals are exposed to the bacteria, they may become infected. Another concern with CL is that it’s a zoonotic disease, which means it can also infect people. Although human infection is rare, take sanitary precautions when treating and handling infected animals. Always wear disposable gloves, and wash your hands and…

    Exotic Pets

    Exotic animals are usually animals that are not native to our land. Because of this, they can present a biological threat to the public. Although all animals harbor and can transmit bacteria, pathogens, and viruses to humans that have the potential to cause illness, many people associate these pet-related illnesses with unusual or exotic pets. A zoonotic disease is an infectious disease that can be transmitted from animals to humans (Smith, “Exotic Pets Zoonotic Disease”, par. 6). There is controversy over diseases that are claimed to be spread by exotic pets. Many people who argue for the banning of exotic pets present an illusion that diseases are spread by exotic pets, and that non-exotic pets in comparison are “clean and safe” to own. Although approximately 70 percent of emerging diseases come from “wildlife”, those animals are animals that exist in the wild, while most of the commonly kept exotic pets are captive bred (Smith, Exotic Pets…

    Still, the construction will lead to environmental pollution. For example thermal pollution will lead to the increasing number of infectious disease-causing vectors since the river and air temperature is conducive to them. High temperature encourages the multiplying of vectors such as rats, mosquitoes, fleas and ticks. The spread of vectors such as mosquitoes can cause diseases such as malaria, dengue and yellow fever. Meanwhile, high rate production of rat also occurred. These…

    Fertilizer, animal manure, and waste-treatment plant effluent all contain nutrients that stimulate excessive plant and algal growth in freshwater bodies. When the plants die and decompose, dissolved oxygen is depleted, causing die-offs of fish and other species living in the water. Persistent organochlorine insecticides, such as DDT, deposited in lake sediments can bioaccumulate, harming the fish and birds that eat them.Human and animal fecal waste contain disease-carrying organisms such as the bacterium Escherichia coli (E. coli) and pathogens that causes cholera, typhoid, and cryptosporidiosis. Cholera is rarely seen in the United States, but E. coli outbreaks are not rare, and in 1993, more than fifty people died, and an estimated 400,000 became ill from a massive outbreak of cryptosporidiosis in Milwaukee, Wisconsin. The outbreak was attributed to a failure in drinking water treatment, allowing the cyst form of the parasite, introduced by animal waste, to pass into tap water…

    Leptospirosis

    Wild mammals are known to be the main reservoir of the leptospiral serovars. About 160 mammals including fats, skunks, raccoon, and cattle, have been termed as vectors or carriers of the disease. Rats are considered to be the most important reservoir. Transmission occurs by contamination of soil, water, or vegetation by urine excreted from infected animals. Humans can become infected upon contact of the contaminated material with abraded skin, mucous membranes such as conjunctiva or alimentrary tract, or ingestion of the contaminated material. Occasionally, the organism may even enter the body through intact skin. Infection has occurred after animal and rodent bites, after contact with abortion products of infected…

    According to the Centers for Disease Control and Prevention (CDC),” when used properly pesticide sprays increase crop production, preserve produce, combat insect infestations, and control exotic species” (Centers for Disease Control and Prevention, 2011). However, if safety measures are not enforced and these products are not adequately regulated, they may result in Acute Pesticide Poisoning, or APP. The CDC tells us that “agricultural workers, groundskeepers, pet groomers, fumigators, and a variety of other occupations are at risk for exposure to pesticides…” (Centers for Disease Control and Prevention, 2011). The Food and Agriculture Organization of the United Nations also points out that “malnutrition and dehydration increase a person’s sensitivity to pesticides” (Food and Agriculture Organization of the United Nations, 2004). This is one of the reasons that APP is more…
