| Impact of Parasites on Food Security - Technology Times Pakistan Posted: 27 Feb 2019 02:15 AM PST 
Food security has very clear and important objectives which include elimination of poverty, ensure environmental sustainability and global development. Food production from livestock sector has less negative impact on environment than agriculture sector because agriculture sector plays major role in climate change in term of greenhouse gases. But health of livestock is very important to get proper production. It can be achieved with the help of good management, nutrition, proper vaccination, breeding program and bio-security. In case of negligence, there is high risk of parasitic infestation. These parasites cause diseases of gastro-intestinal tract, respiratory system and skin which have negative impact on feed intake, growth rate, fertility, milk yield, carcass weight, carcass composition and wool growth. Livestock diseases were ranked on the basis of impact on poor people. Four parasitic diseases fell into 1-10 top most important diseases in which GIT Helminthes fell on 1st, Ectoparasites on 4th, Liver Fluke on 6th and Toxocara vitulorum on 10th position. Technology and Rural Development are the basic components of Food Security and almost have equal importance. If industry does not adapt the technology, then food security will not be achieved. Similarly, Knowledge, Vaccination, Diagnostic Techniques, disease control and prevention programs require to reach the target population timely and in the proper formats for rural development. "WormBoss" is one of the best examples of rural development that exists at present time. Main focus of WormBoss is to decrease unwanted drenching and to reduce drench resistance when animal production is increasing. An important existing period of veterinary parasitology was explanation of epidemiology and clarification of pathogenesis of different parasite species such as Fasciola hepatica, Ostertagia ostertagi, Dictyocaulus viviparous and Teladorsagia circumcinta. Due to rise in quantitative epidemiology, studies on relation between parasites and their hosts increased, and statistical data help in proper understanding of impact of parasitic diseases worldwide. Research achievements on some important parasites and parasitic diseases supported the food production in the past and will make sure food security in the future. It can be achieved by adaptation of vaccination and disease control program and by the advancement of diagnostic techniques. Anthelmintic resistance is currently a big issue worldwide. Resistance develops due to under dosage of drug, overuse of Anthemintics and absence of new drugs. Food security cannot be achieved in the absence of new Anthelmintics and its registration. Prevalence of Ostertagia ostertagi in cattle and Teladorsagia circumcinta in sheep is high in temperate regions. These parasites cause loss of appetite and hypoprotenimia which ultimately result in abomasal tissue damage and loss of production. Some trematode species such as Fasciola hepatica (Liver Fluke) and Fasciola gigantica cause acute, sub-acute and chronic form of diseases in sheep and cattle, and prevalence of these parasites is high in temperate and tropical regions respectively. Manifestation of both parasites leads to decrease growth rate, low milk production and infertility. Liver fluke is most common cause of liver condemnation in slaughter houses, therefore it is clearly against the food security agenda in terms of reducing waste. Duration of pre-patent period of liver fluke is long therefore diagnosis of liver fluke in the live animal has different problems resulting in damage to productivity before the detection of liver fluke's eggs in feces. Vaccination against fluke infestation of cattle and sheep is very necessary but it has some problems such as deficiency of naturally acquired immunity in both species, rise of infection through intermediary species and wildlife also play a major role in maintenance of infection in these species. But transmission of fluke can be reduced via vaccination, resulting in decreased egg production and pasture contamination over a few seasons. There is an additional benefit of vaccination of livestock that is reduction in zoonotic risk of F. hepatica to human, particularly in those countries where human diet contains aquatic vegetation. Some interesting studies show that F. hepatica produces anti-inflammatory condition in its host, and host becomes susceptible to other pathogens like Salmonella dublin and Clostridium sp. Bacterial infections also have negative impact on growth rate, milk production and fertility. Poor reproductive efficiency is one of the most important limitations to balanced food production. Abortion and infertility are common in ruminants due to improper breeding, poor nutrition and infectious diseases. Toxoplasmosis in sheep and Neosporosis in cattle are most important protozoal causes of reproductive disease. Toxoplasma gondii causes abortion in sheep and it also causes zoonotic infecton in human via ingestion of under-cooked meat containing tissue cysts. Neospora caninum is one of the most significant causes of bovine abortion globally. It causes direct economic losses by loss of pregnancy, notable loss of production in dairy and beef sector, and the costs of test and cull program. Parasitologists have contributed to Food Security before the term was originated. Work of parasitologists based on description of life cycle and epidemiology of parasites and their relation with various hosts. After the discovery of levamisole, benzimidazoles and macro-cyclic lactones, it could be declared that livestock helminthology became a "Cinderella" subject. Different research councils in the world such as Biotechnology and Biological Science Research Council (BBSRC) and Research Councils UK (RCUK) have decided to work together on Global Food Security initiative. Horizon 2020, a research and revolution program of European Union completely focus on Food Security, Bio-economy and sustainable Agriculture. Progress on vaccination against parasites in livestock showed that veterinary parasitologists potentially lead the discipline in term of Food Security. Parasitologists are also contributing in development of vaccine against human parasitic diseases including Malaria, Hook Worm and Sleeping Sickness. In conclusion, future of Veterinary Parasitology and Parasitologists is bright but important thing is that, how to describe to educated population about recent contributions of parasitological research in Global Food Security. This may depend upon parasitologists, how they explain the results of their research and translate into a language that brings proper understanding and impression for those who want to ensure food security in future. https://www.technologytimes.pk/impact-parasites-food-security/https://www.technologytimes.pk/wp-content/uploads/2019/02/Impact-of-Parasites-on-Food-Security.jpg https://www.technologytimes.pk/wp-content/uploads/2019/02/Impact-of-Parasites-on-Food-Security-150x69.jpgArticlesfood,impact,parasites,SecurityNowadays, everyone's agenda is "Food Security".

Global Cattle Health: Market Insights The cattle health market is typically being fueled by the increasing beef consumption along with the rising demand for animal protein. Cattle are most prone to a number of infections including viral, bacterial and parasitic. Cattle also experience various shocks from environmental factors such as high heat and humidity. Another major factor impacting cattle health is mud, as they graze in farms they are prone to high health risk due to excessive muddy conditions leading to cattle health problems such as foot rot, scoure etc. Dietary deficiencies are the second common cause of weakness and weight loss in cattle leading to deteriorating conditions like malnutrition and also reproductive failure ultimately affecting the cattle population. Maintaining good cattle health is necessary as cattle food production sector gets hampered due to poor cattle health and also restrains the growth of cattle health market. In developing countries cattle as used for farming purposes so it also affects the production in agricultural sector. Increase in research & development for cattle health is proven by the increase in the cattle health spending. According to the Animal Health Institute (AHI), AHI member companies spend about 10-12% of their sales for investment in new innovation in animal health. Some of the other factors such as, increasing initiatives by government and inclusion of insurance policies globally along with advancements in technology are also expected to drive the growth of the cattle heath market. Vaccination programs are the basic tools for preventing disease and maintaining cattle health by decreasing the death rate and improving productivity so many players in cattle health market are focusing on vaccination programs this factor is anticipated to increase high revenue shares in cattle health market. However regulatory challenges and incompatible cattle heath information may hinder the growth of the cattle health market. Delays in the public sector testing and registration process of new cattle heath products is common worldwide.

| Woman Pulls Parasitic Cattle Eye Worm From Her Own Eye - Smithsonian.com Posted: 13 Feb 2018 12:00 AM PST  In August of 2016, Abby Beckley felt the tickle of what she thought was an eylash stuck in her eye. But there was no hair causing the irritation. As Erika Engelhaupt reports for National Geographic, it was a worm. Actually, it was many worms. Beckley figured out this gruesome reality after days of constant irritation. Her eye turned red, her eyelid drooped, but she still had no clue what was going on. Finally five days after the issue began, when the salmon fishing boat she was working on returned to port in Craig, Alaska, she decided to take action. Beckley pulled up her eyelid, pinched at the skin and extracted a tiny translucent worm. While her find is truly disgusting, it's also scientifically interesting. Beckley was infested with an eye worm species called Thelazia gulosa. It was the first time this particular parasite had ever been found in humans, writes Engelaupt. Beckley and her roommate initially believed the worm might have come from the salmon they work with, since those fish can often harbor parasites, reports Sandee LaMotte at CNN. They searched for the condition online but found no connection between salmon worms and humans. And a local doctor had no suggestions. "I could see them moving across my eye at that point, too. There were so many," Beckley tells LaMotte. Eventually, friends and family convinced her to return home to Portland, Oregon. There, she went to see doctors at Oregon Health and Science University in Portland. While at first some doctors suggested the "worms" she was finding were just strands of mucus, she convinced them to wait and watch. "I am thinking to myself, 'Worms, please show up,' because sometimes they would go behind my eye and under the eyelid, and you couldn't see or feel them anymore." She tells LaMotte. After half an hour, the wrigglers made their debut. "I felt one squiggle across my eye, and I told the doctors, 'You need to look right now!' I'll never forget the expression on their faces as they saw it move across my eye." Doctors collected samples of the worms and sent them to the Centers for Disease Control, which identified the worm as Thelazia gulosa, an eye parasite found in the U.S. and Canada. But until now, it had only been seen in the eyes of cattle. Beckely's ordeal is discussed in a new paper in The American Journal of Tropical Medicine and Hygiene. The study documents the 11th time eye worms infected a person in North America. But it was the first time this particular species, a cattle worm, infected a human. There are two other species of Thelazia worms that infect humans, and Beckley's infection represents a third species now known to parasitize humans. So how did Beckley acquire the infection? According to the CDC, eye worms are spread by species of "face flies," which feed on eye secretions. According to Engelhaupt, the worm larvae crawl from the flies into the eyes of the animals they're feeding on, where they transform into adults and produce larvae. That larvae then need to hop back on board a face fly to complete its complicated life cycle. It's thought that Beckley, who spends much of her time outdoors, picked up the worms while horseback riding and fishing along the coast of Oregon where cattle are common. Since face flies normally don't bother humans, Beckley's worm colony would have likely died out on its own if she hadn't noticed the wrigglers. She tells LaMotte she thinks others may have experienced a similar infection but weren't lucky—or unlucky enough—to pull a worm out of their eye like she did. "Dollars to doughnuts, there were people in the past that had these infections but were never specifically diagnosed," William Schaffner, a professor of medicine at Vanderbilt University's Division of Infectious Diseases who not involved in the study, tells LaMotte. "Here, we have someone who developed this unusual infection, and the physicians were interested enough to send the materials to the CDC, where they have extraordinary diagnostic abilities." Thankfully, 20 days after finding the first worm Beckley tugged the fourteenth and last out of her eye. Her vision is back to normal and the worms have left no lasting damage, except for psychological scars. While this infection is likely extremely rare, according to a press release, another species of Thelazia eye worm has spread across Europe in recent years, carried by fruit flies. Apparently, flies capable of carrying the worms are also found in New York, but the worm has not yet been found in North America. Beckley isn't the only American dealing with parasites in her eye. Earlier this week, doctors in Tampa found and removed a pork tapeworm that nestled into the vitreous chamber of a man's eye. If the worm died in the eye, it likely would have caused him to go blind. But if it lived and released larvae, they could have gravitated to his brain, turning it into Swiss cheese. Thankfully, that type of infection is very rare and is only caused by eating undercooked pork. Like this article?  |
