Where does B. abortus affect cattle?
Of the three species B. abortus, principally affects cattle. In cattle, the disease localizes in the reproductive organs and/or the udder. Bacteria are shed in milk, aborted fetuses, afterbirth, or other reproductive tract discharges. There is no way to detect infected animals by their appearance.
How do you get leptospira?
Transmission of leptospira often involves direct contact with urine, placenta, or milk. It can be transmitted during breeding and through the placenta to the fetus. The most common transmission is through infected urine in the environment. Dairy feeder calves in commercial feedlots sometimes suckle the sheaths and scrotums of other calves in the pen. This would be a direct contamination of infected urine from carriers by this suckling habit. A calf rearing system of calf hutches does help to prevent spread of this disease. Leptospira can also survive in the environment, favoring moist and moderately warm temperatures. Leptospira can survive for extended periods in stagnant water (i.e. waterholes in pens). Survival of leptospira is short lived in dry soil, cold temperatures, or very hot temperatures. Therefore outbreaks are most common in dairy calves in the fall and spring.

The bacteria that cause Johne’s Disease can be transmitted in milk, manure and also transmitted to a fetus in the uterus. Calves are often infected by swallowing manure from the environment or from contaminated colostrum. Because the disease has a two to four year incubation period, blood testing may not be effective until the heifers are at least two years old. Animals testing positive with the disease cannot be treated and must be culled.

What are the microorganisms in cow dung?
Animal manure like freshly passed Cow dung is known to harbour a plethora of microorganisms which can be pathogenic to both animals and humans.6 Many pathogenic microbes are found in cow dung, but he extent to which they survive in the environment or manure depends basically on the characteristics of the particular organisms, the source and chemical composition of manure (like ammonium content), pH, dry matter, temperature, oxygen, microbial competition and moisture.5 Many authors have quoted that bacteria like Salmonella spp., faecal coliforms and Enterococcus spp. can be found in Cow dung.5 Also, bacteria like Campylobacter spp., Listeria monocytogenes and Yersinia enterocolitica can also be traced in Cow dung.7 Among parasites, the most important and widely prevalent ones in Cow dung are Ostertagia sp., Trichostrongylus sp., Cooperia sp., Oesophagostomum spp., Taenia spp., Toxocara spp., Giardia spp. and Fasciola spp.1 Eggs like Toxocara vitulorum are important and often found in stool of calves and adult cows also.8 Cryptosporidium is an acid fast protozoan parasite that commonly infects calves and other mammalian hosts, and can be transmitted to man.9 Cryptosporidiosis poses a significant problem in dairy calves where the prevalence of infection is high, and leads to losses due to increased treatment costs and occasionally can even result in mortality.9 The temperature, humidity and rainfall of tropical countries are highly favourable for parasites. Like other diseases, parasitic infections cause economic losses like mortality in cattle, stunted growth, loss of body weight gain leading to poor quality of skin, decreased milk and meat production.1,10 In a study in Bangladesh, about 40% of cow dung samples showed one or more parasites.1 About 30% of these samples showed coccidian parasites in Cow dung.1 Also, raw manure and improperly treated manure can act as a source of contamination of soil, air and water by pathogens, which in turn can result to critical public health issues.5

How to reduce pathogens in cow dung?
The best management practices to reduce pathogens in livestock wastes focus in three angles: reducing pathogens in the animals, during manure collection and storage and lastly during land application of manure.5 Even a small bit of reduction in pathogens in cow dung can make manure and pit soil much safer for humans. Such methods are air drying, Ultraviolet irradiation ad anaerobic storage in lagoons and tanks.5 Other physical methods like Pasteurization and chemical methods like treatment by Lime and Hydrogen peroxide can also effectively reduce microbial load in cow dung.5 Out of these, lime treatment is advocated because of its cost-effectiveness, easy disposal of the treated manure as well as the resultant reduction in soil acidity.11
What is cow dung used for?
Cow dung is used commonly in rural and periurban households in India for many purposes like for cooking and mopping floors. However it can contain many pathogenic bacteria and parasites like Escherichia coli, Cryptosporidium spp. and Entamoeba histolytica that can be infectious tothe handlers and farmers. Hence one should be very careful while handling these. Thus a study of pathogenic microbial flora in cow dung is of utmost public health importancein our country and very little literature is available regard it. Hence, we here have tried to summarize available information in this aspect.
Is cow dung infectious?
Hence cow dung is highly infectious to man and should be dealt with very carefully. It has been estimated and shown also that about a hundred infections may be transmitted from animal to animal and that more than 150 infectious diseases may also be transmitted as well from animal to man.12 So the people handling the cow dung samples are at great risk of acquiring infections also. Such studies are rare especially in India, Our study is hence quite important in this regard. However we will carry out further research in this aspect since this is an important avenue of public health research. In the field of one health it demands more importance.
Is cow dung a good source of bacteria?
Cow dung is a potent source of bacteria and parasites and hence should be handled and disposed carefully. Its use in farms and households as bio fertilizer and biofuel should be restricted.
Where Do These Bacteria Come From and How Do They Get Into Surface Waters?
The fecal material in these sources comes from warmblooded animals including humans, pets, wildlife, and farm animals. Many of the bacteria within feces can survive in environments outside of the animal, thereby elevating bacteria concentrations as they enter a stream. EPA estimates that one dairy cow can produce about 120 pounds of wet manure in a day, with 80 percent being water2. On the other hand, humans account for 3 to 6 pounds per day, and a goose averages about 0.34 pounds of wet droppings per day. These values indicate that even a small quantity of fecal material escaping into surface water from livestock can cause a substantial impact. Regardless of whether the polluting animals are sick or healthy, they can transmit pathogens in their manure. However, those that are sick are much more likely to shed pathogens. Thus, good on-farm sanitation practices, healthy diets and good animal husbandry will help decrease pathogen release from livestock3. Fecal material also contains nutrients and organic matter. Nutrient addition to surface waters, particularly phosphorus and nitrogen, can increase algal growth, decrease water clarity, and increase ammonia concentrations which can be toxic to fish. The increased organic matter also serves as a food source for bacteria and other microorganisms, resulting in lower oxygen levels in the water, and often no oxygen in deeper bottom waters.
How much manure can a dairy cow produce?
EPA estimates that one dairy cow can produce about 120 pounds of wet manure in a day, with 80 percent being water2.
Why don't we monitor for pathogens?
Measuring just one pathogen does not provide information on the others that may also be present. Thus, presence of E. coli bacteria is used as an indication of the presence of pathogens. The EPA recommended standards for E. coli in recreational waters are based on a threshold concentration. When those numbers are exceeded, the health risk from waterborne illness is deemed unacceptably high1.
What organisms are responsible for swimming in polluted water?
In most states, including Michigan, the organism (indicator) used to determine if the water quality standard for recreation is exceeded is E. coli, even though it is usually other bacteria, viruses and protozoa that cause many of the illnesses associated with swimming in and ingesting polluted water. If E. coli is present in certain quantities, ...
