Typhoid bacteria

Typhoid Bacteria Food Poisoning — In 1972, members of a U.S. fascist group called Order of the Rising Sun were found in possession of 30 to 40 kilograms of typhoid bacteria cultures they planned to use to contaminate water supplies in Chicago, St. Louis, and other large Midwestern cities. 

According to Ishiwara [71], after a 30 min action a 0.04% aqueous solution of picric acid exhibits bactericidal activity against typhoid bacteria, staphylococci, streptococci and gonococci. 

But despite these examples of biochemical evolution and modification in progress, to which more are being added as the science of comparative biochemistry matures, it remains true that the biochemical composition and organization of all the forms of life now present on earth demonstrate unity a unity quite at variance with their more obvious differences in gross structure and behaviour. Most of us would hesitate to compare ourselves with fish, typhoid bacteria, cancer cells, or even oak trees, yet the fact is that we have very much more in common with them than we might have guessed. 

In 1988, the Iraqi army deliberately introduced typhoid bacteria into the water supply of the Kurdish city of Sulaimaniyah, bringing about an outbreak [157]. 

Even if your symptoms seem to go away, you may still be canning S. Typhi. If so. the illness could return, or you could pass the disease to other people. In fact, if you work at a job where you handle food or care for small children, you may be barred legally from going back to work until a doctor has determined that you no longer carry any typhoid bacteria. 

Bacteria are smaller than protozoa and are responsible for many diseases, such as typhoid fever, cholera, diarrhea, and dysentery. Pathogenic bacteria range in size from 0.2 to 0.6 /tm, and a 0.2 /tm filter is necessary to prevent transmission. Contamination of water supplies by bacteria is blamed for the cholera epidemics, which devastate undeveloped countries from time to time. Even in the U.S., E. coli is frequently found to contaminated water supplies. Fortunately, E. coli is relatively harmless as pathogens go, and the problem isn t so much with E. coli found, but the fear that other bacteria may have contaminated the water as well. Never the less, dehydration from diarrhea caused by E. coli has resulted in fatalities. 

Pathogenic organisms Bacteria, viruses or cysts which cause disease (typhoid, cholera, dysentery) in a host (such as a person). There are many types of bacteria (non-pathogenic) which do NOT cause disease. Many beneficial bacteria are found in wastewater treatment processes actively cleaning up organic wastes. 

Killing. The proeess by which the live bacteria in the culture are killed and thus rendered harmless. Heat and disinfectants are employed. Heat and/or formalin are required to kill the cells of Bordetella pertussis used to make whooping-cough vaccines, and phenol is used to kill the Vibrio cholerae in cholera vaccine and the Salmonella typhi in typhoid vaeeine.

The biological contamination and the hardness of underground water are the two very serious problems of water. Dissolved salts deteriorate water quality and may cause diseases related to joints and bones, while infected water may cause many water-borne diseases such as cholera, dysentery, typhoid etc. Ultrasound may disinfect the potable water by blasting off micro organisms such as zooplanktons, phytoplanktons, pathogenic bacteria and produce germ-free water in few minutes of... 

Dependence of survival from typhoid on the constitution of the host and the virulence of the bacteria (Gowen). 

In many countries, water is not safe to drink. Untreated water is sometimes polluted with toxic chemicals. It may also carry numerous water-horne diseases, including typhoid fever, cholera, and dysentery. In Canada, the water that comes through your tap has heen through an elaborate purification process. This process is designed to remove solid particles and toxic chemicals, and to reduce the number of bacteria to safe levels. Adding chlorine to water is the most common way to destroy bacteria.

Bacteria in water are usually thought of in terms of human disease. Indeed, until quite late in the nineteenth century, disastrous outbreaks of waterborne diseases such as cholera, dysentery, and typhoid fever were common in the major cities of the world. The last outbreak of typhoid in the United Kingdom occurred in Croydon in 1937. Serious cholera epidemics still occur in some parts of the world one that began in Peru in 1991 spread to several countries in the Americas, causing 391,000 cases of illness and 4000 deaths that year. 

Another common source of groundwater pollution is sewage, which includes drainage from septic tanks and inadequate or broken sewer lines. Animal sewage, especially from factory-style animal farms, is also a source of groundwater (and river water) pollution. Sewage water contains bacteria, which if untreated can cause waterborne diseases such as typhoid, cholera, and infectious hepatitis. If the contaminated groundwater travels relatively quickly... 

There are a number of harmful microbes and bacteria in the soil. The harmful microbes like typhoid and dysentery germs can contaminate rain water as it seeps through the soil. 

Chloramphenicol. Chloramphenicol (Chloromycetin) is a synthetically produced agent that exerts antibacterial effects similar to those of erythromycin that is, it binds to the 50S subunit of bacterial ribosomes and inhibits peptide bond formation. Chloramphenicol is a broad-spectrum antibiotic that is active against many gram-negative and gram-positive bacteria. This drug is administered systemically to treat serious infections such as typhoid fever, Haemophilus infections such as osteomyelitis, rickettsial infections such as Rocky Mountain spotted fever, and certain forms of meningitis. Chloramphenicol may also be administered topically to treat various skin, eye, and ear infections.
