Mouse Life

Rats are mammals belonging to the tribe muridae sewer rat (Rattus norvegicus) is found almost in all countries and is an important model organism in biology and is also a popular pet.The types of mice:1. house rat (Rattus rattus)2. sewer rat (Rattus norvegicus)3. rice field rat (Rattus argentiventer)The house mouse (Rattus rattus) is an easy common rodent found in homes with a long tail and clever climb and jump. These animals included in sub Murinae and comes from Asia. However, he then spread to Europe through trade since the beginning of the modern calendar and actually spread in the 6th century. Subsequently it spread to all corners of the world. House mice in the present tends to spread in warm regions because in cold regions can not compete with sewer rats.Unlike his rival, rats, house mice are poor swimmers and their carcasses are often found in the wells. Nevertheless, he is more agile and great climbers, and even dare to "fly". The color is usually black or light brown, although there are now bred with white or striped. The size is usually 15-20 cm with a tail of ± 20cm. These animals are nocturnal and omnivorous, but prefer grains. Females can give birth at any time, with children 3-10 tail / birth. Reaches 2-3 years of age and like to live in groups.Sewer rat, brown rat, house rat large or laboratory rats (Rattus norvegicus) is one of the most common rat species found in urban areas. The selection of animals is widely used as experimental animals (known as white mice) and as pets (with the colors vary).Medium-sized rodents, tend to be smaller than rats, with a length of 30-40cm (including tail). Yellowish brown hair color. His belly gray-haired with white edges. Argentiventer name means "silver belly". Its tail is brown.





Diseases of the RatMice in addition to the resulting loss in meteril and aesthetics mice also transmit the seeds of disease in animals and humans. Diseases from rodents are:
    
1. The first mouse disease is also called the Plague PES disease caused by the bacterium Yersinia pestis. The disease is spread by rat fleas bite, the bite of an infected rat or animal body and contact with infected animals. There are three types of diseases plague bubonic plague, septicemic plague, pneumonic plague are common symptoms of fever, chills, dizziness, weakness, symptoms of bubonic plague have a special on a fluid-filled swelling at the site of the bite, the septicemic bleeding under the skin and internal organs, blood clots, organ of the body is not works well, is the pneumonic symptoms similar palgue pneumonia (inflammation paru2) among the three types of plague are pneumonic plague is the most dangerous because it can spread through the air or human to human transmission.
    
2. Mice that both murine disease caused by organisms Typus ricketsial type of bacteria. Spread by rat fleas and cat fleas that have been contaminated with rat TSB, the incubation period of murine thypus 6-14 days symptoms are headache, fever, nausea, pain, 5-6 days after symptoms first occur in the throat rash then spreads to the hands and feet if left the disease will last up to several months.
    
3. The third rat disease Salmonellosis is caused by salmonella bacteria. Spread through contaminated food rat droppings. Symptoms of vomiting, diarrhea, headache, dehydration, fever and chills.
    
4. Disease following rat-bite fever Rat (rat bite fever) caused by the bacterium Streptobacillus moniliformis that can be contained in the saliva of rats. Symptoms usually bite wounds heal, but after about 10 days arise chills, fever, vomiting, headache, backache, joint pain, a small reddish spots appear on the hands and feet. There could be complications of heart valve infections and abscesses of the brain or other tissues.
    
5. Moderate rat disease leptospirosis is caused by Leptospira bacteria and spread by rat urine. Usually the disease is spread during floods and transmitted through the mouse. These bacteria enter the body through broken skin or mucous membranes such as eyes and nose when washing the face. Therefore, for prevention should use boots when cleaning up flood and wash your face with clean water is not contaminated with rat urine because sometimes the rats left in the bathroom when they search for water.
    
The initial symptoms of this disease fever chills, muscle pains (especially calves and back), headache, sore throat, dry cough, nausea, vomiting until mencret2. At an advanced stage will appear symptoms such as jaundice (skin and whites of the eyes become yellowish) because these bacteria invade the liver. Complications to the lining of the brain can cause headache, kejang2, stiff neck and decreased consciousness.
    
Treatment in the early days is very easy to do because it simply with antibiotics therefore consult a doctor if there are indications of disease TSB.HOW eradicate RATSHow to Eradicate Rats effective to date is rat traps and poison bait.1. Rat TrapSome of the advantages if we eradicate mice using trapping methods are:• Without a poison so much safer than poison bait.• There is no problem as usual smell of carrion diketemui when using poison baits.• There is tangible evidence of the capture of mice.Mice are very sensitive to new objects around it, including a trap that we put therefore the initial installation of a trap let the trap is not enabled for several days until the bait is placed in the trap eaten by rats, mice eat the bait after trap switch.Use lures that are sticky like peanut butter mixed with raisins, bread, chocolate and so they usually eat your home. Replace the trap with a sufficient amount between 50-10 traps perlubang / den with a distance of 50 cm between traps because generally a failure in the use of traps due to the small number of traps used. If using a live trap release the mouse in place that is not their habitat if released from the mice will go back to your home or to other people's houses. Be careful if they let the rat bite can cause disease, use of gloves in addition to reducing the risk of bites also avoid human scent on the trap. How to Eradicate mice using a trap is suitable for areas that do not allow contamination, such as food storage area because it was feared when using toxins will contaminate food if carried by rats.2. Poisson Bait / Poison BaitHow to exterminate mice using poison bait is very effective because it is very easy to apply and gives quick results, but the poison bait has a weakness that is the problem of dead rat smell of carrion, especially in areas that we can not reach. Be careful in putting the poison bait in places where children, pets or other animals used to play, in order to safely use a special container (stanza station) to prevent this.The content of poison bait is currently widely used is brodifacum or bromodiolone which is toxic anticoagulant. Anticoagulant poison is poison poison slowacting low-power and takes a few days after bait is consumed so that the mice die so there is no deterrent effect on mice. Lack of high toxicity to mice is causing a deterrent effect, so just kill the little rats because rats do not want to eat after the toxin.How to prevent entry of mice into the house:• There should be absolutely no food outside. Find a tin / cabinet meeting once.• There should be no shred of food outside.• There should be no waste at all. Direct wet garbage placed outside the home. Especially at night, there should be no trash in the house• The holes pipe / ground is all covered. If not cemented it in a tightly closed wire gauze.• Spread rat poison where traffic mice.

Integrated Pest Management (IPM)


Integrated Pest MANAGEMENT Is the integrated pest control methods that are effective, efficient, competitive as well.

Method: Integrated Pest Management
a. Initial Service (month I)
b. Regular Service (month II - ...)
Period of contract: Min. 1 year
Scope of pests: a. Flying insects (fly, mosquito etc..), Seemed insects
(all species cocrouch, ant, spider, centipede, etc.)
B. Mice (all types)

JOB PROCEDURES


Employment procedures will be conducted as follows:

Control of pests with the overall goal to eliminate the pest population (zero-pest population). Initial Service will also be accompanied with the advice & recommendations on improvement of sanitation, closing access to pest entry, the nest and other suggestions to support the success of the control.

b. Regular Service
Pest control methods with the "Inspected-Treated" with the goal to eliminate re-infestasi pests that come from the surrounding environment. With regular service is expected pest population growth can be terminated since the new early. Regular service will also be accompanied with the advice & recommendations on improvement of sanitation, etc. that are found during routine monitoring and inpeksi.


To control mice, performed with the integrated control method "3 Rings Monitoring System", namely:

Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia

Rodentia is an order of mammals also known as rodents, characterised by two continuously-growing incisors in the upper and lower jaws which must be kept short by gnawing.[1][2]

Forty percent of mammal species are rodents, and they are found in vast numbers on all continents other than Antarctica. Common rodents include mice, rats, squirrels, chipmunks, gophers, porcupines, beavers, hamsters, gerbils, guinea pigs, degus, chinchillas, prairie dogs, and groundhogs.[1] Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating stored human seeds and spreading disease.

Size and range of order

In terms of number of species — although not necessarily in terms of number of organisms (population) or biomass — rodents make up the largest order of mammals. There are about 2,277 species of rodents (Wilson and Reeder, 2005), with over 40 percent of mammalian species belonging to the order.[3] Their success is probably due to their small size, short breeding cycle, and ability to gnaw and eat a wide variety of foods. (Lambert, 2000)

Rodents are found in vast numbers on all continents except Antarctica, most islands, and in all habitats except oceans. They are the only placental order, other than bats (Chiroptera) and Pinnipeds, to reach Australia without human introduction

Characteristics

The capybara, the largest living rodent, can weigh up to 65 kg (140 lb).

Many rodents are small; the tiny African pygmy mouse can be only 6 cm (2.4 in) in length and 7 g (0.25 oz) in weight at maturity, and the Baluchistan Pygmy Jerboa is of roughly similar or slightly smaller dimensions. On the other hand, the capybara can weigh up to 80 kg (180 lb)[4], and the largest known rodent, the extinct Josephoartigasia monesi, is estimated to weigh about 1,000 kg (2,200 lb), and possibly up to 1,534 kg (3,380 lb)[5] or 2,586 kg (5,700 lb)[6].

Rodents have two incisors in the upper as well as in the lower jaw which grow continuously and must be kept worn down by gnawing; this is the origin of the name, from the Latin rodere, to gnaw, and dens, dentis, tooth. These teeth are used for cutting wood, biting through the skin of fruit, or for defense. The teeth have enamel on the outside and exposed dentine on the inside, so they self-sharpen during gnawing. Rodents lack canines, and have a space between their incisors and premolars. Nearly all rodents feed on plants, seeds in particular, but there are a few exceptions which eat insects or fish. Some squirrels are known to eat passerine birds like cardinals and blue jays

Rodents are important in many ecosystems because they reproduce rapidly, and can function as food sources for predators, mechanisms for seed dispersal, and as disease vectors. Humans use rodents as a source of fur, as pets, as model organisms in animal testing, for food, and even for detecting landmines.[7]

Members of non-rodent orders such as Chiroptera (bats), Scandentia (treeshrews), Insectivora (moles, shrews and hedgehogs), Lagomorpha (hares, rabbits and pikas) and mustelid carnivores such as weasels and mink are sometimes confused with rodents.

Evolution

The fossil record of rodent-like mammals begins shortly after the extinction of the non-avian dinosaurs 65 million years ago, as early as the Paleocene. Some molecular clock data, however, suggest that modern rodents (members of the order Rodentia) already appeared in the late Cretaceous, although other molecular divergence estimations are in agreement with the fossil record.[8][9] By the end of the Eocene epoch, relatives of beavers, dormouse, squirrels, and other groups appeared in the fossil record. They originated in Laurasia, the formerly joined continents of North America, Europe, and Asia. Some species colonized Africa, giving rise to the earliest hystricognaths. There is, however, a minority belief in the scientific community that evidence from mitochondrial DNA indicates that the Hystricognathi may belong to a different evolutionary offshoot and therefore a different order. From there hystricognaths rafted to South America, an isolated continent during the Oligocene and Miocene epochs. By the Miocene, Africa collided with Asia, allowing rodents such as the porcupine to spread into Eurasia. During the Pliocene, rodent fossils appeared in Australia. Even though marsupials are the prominent mammals in Australia, rodents make up almost 25% of the mammals on the continent. Meanwhile, the Americas became joined and some rodents expanded into new territory; mice headed south and porcupines headed north.

Some Prehistoric Rodents
Castoroides, a giant beaver
Ceratogaulus, a horned burrowing rodent
Spelaeomys, a rat that grew to a large size on the island of Flores
Giant hutias, a group of rodents once found in the West Indies
Ischyromys, a primitive squirrel-like rodent
Leithia, a giant dormouse
Neochoerus pinckneyi, a giant North American Capybara that weighed 50 kg (110 lb)
Josephoartigasia monesi, the largest known rodent
Phoberomys pattersoni, the second largest known rodent
Telicomys, a giant South American rodent

Classification

2/3 of rodent species are in the superfamily Muroidea. The families Muridae (blue) and Cricetidae (red) make up the bulk of the Muroidea.

Standard classification

The rodents are part of the clades: Glires (along with lagomorphs), Euarchontoglires (along with lagomorphs, primates, treeshrews, and colugos), and Boreoeutheria (along with most other placental mammals). The order Rodentia may be divided into suborders, infraorders, superfamilies and families.

Classification scheme:

ORDER RODENTIA (from Latin, rodere, to gnaw)

Alternate classifications

The above taxonomy uses the shape of the lower jaw (sciurognath or hystricognath) as the primary character. This is the most commonly used approach for dividing the order into suborders. Many older references emphasize the zygomasseteric system (suborders Protrogomorpha, Sciuromorpha, Hystricomorpha, and Myomorpha).

Several molecular phylogenetic studies have used gene sequences to determine the relationships among rodents, but these studies are yet to produce a single consistent and well-supported taxonomy. Some clades have been consistently produced such as:

The positions of the Castoridae, Geomyoidea, Anomaluridae, and Pedetidae are still being debated.
