THE ZIKA VIRUS.

On Monday (Jan. 25), the World Health Organization announced that Zika virus, a mosquito-borne illness that in the past year has swept quickly throughout equatorial countries, is expected to spread across the Americas and into the United States. Zika virus is transmitted by the mosquito species Aedes aegypti, also a carrier of dengue fever and chikungunya, two other tropical diseases. Though Aedes aegypti is not native to North America, researchers at the University of Notre Dame who study the species have reported a discovery of a population of the mosquitoes in a Capitol Hill neighborhood in Washington, D.C. , the team identified genetic evidence that these mosquitoes have overwintered for at least the past four years, meaning they are adapting for persistence in a northern climate well out of their normal range. This mosquito is typically restricted to tropical and subtropical regions of the world and not found farther north in the United States than Alabama, Mississippi, Georgia and South Carolina. What this means for the scientific world," said Severson, who led the team, "is some mosquito species are finding ways to survive in normally restrictive environments by taking advantage of underground refugia. Therefore, a real potential exists for active transmission of mosquito-borne tropical diseases in popular places like the National Mall.(source ;science daily) The emergence of mosquitoes in normally restricted areas has exposed the pandemic potential of the ZIKA VIRUS,with pregnant women at highest risk.Prevention of mosquito bites through use of treated nets,insecticides,and clearing environment of stagnant water,destruction of developmental stages and more recently the introduction of genetically modified mosquitoes to wipe out the infective strains have all been employed to reduce disease incidence. Travelling to zika-risk zones by pregnant women has also been initiated as they are mostly prone to the infection.

FIBER RICH DIET REDUCES RISK OF LUNG DISEASE.

A diet rich in fiber may not only protect against diabetes and heart disease, it may reduce the risk of developing lung disease, according to new research. "Lung disease is an important public health problem, so it's important to identify modifiable risk factors for prevention," said lead author Corrine Hanson PhD, RD, an associate professor of medical nutrition at the University of Nebraska Medical Center. "However, beyond smoking very few preventative strategies have been identified. Increasing fiber intake may be a practical and effective way for people to have an impact on their risk of lung disease." Analyzing data from the National Health and Nutrition Examination Surveys, researchers report in "The Relationship between Dietary Fiber Intake and Lung Function in NHANES," that among adults in the top quartile of fiber intake: • 68.3 percent had normal lung function, compared to 50.1 percent in the bottom quartile. • 14. 8 percent had airway restriction, compared to 29.8 percent in the bottom quartile. In two important breathing tests, those with the highest fiber intake also performed significantly better than those with the lowest intake. Those in the top quartile had a greater lung capacity (FVC) and could exhale more air in one second (FEV1) than those in the lowest quartile. Researchers reviewed records of 1,921 adults, ages 40 to 79, who participated in NHANES during 2009-2010. Administered by the Centers for Disease Control and Prevention, NHANES is unique in that it combines interviews with physical examinations. Fiber consumption was calculated based on the amount of fruits, vegetables, legumes and whole grains participants recalled eating. Those whose diets included more than 17.5 grams of fiber a day were in the top quartile and represented the largest number of participants, 571. Those getting less than 10.75 grams of fiber a day were in the lower group and represented the smallest number of participants, 360. Fiber-rich diet has been linked to healthy life style free of risk of heart disease,diabetes,colon cancer and bowel diseases emanating from constipation.This new research (according to American Thoracic Society) sheds light on how fiber reduces risk of lung diseases,further reinforcing the need to include more vegetables,fruits,nuts,oatmeal and other fiber rich sources to our menu. The benefits of fiber-rich meals also has the same results in animals, incorporating vegetables,oatmeal and fruits into their meal has been known to reduce risk of cancer, constipation and as a treatment protocol for diabetic patients and also prevention of diabetes in animals.

Antimicrobial resistance :rats a major link in antimicrobial resistance in animals and man.

The world is faced with the issue of drug-resistance, super bugs and antibiotic residue in animal-by-products,forcing producers to look critically at methods of production and handling of products to resolve these issues. 

The war against super bugs is super hot with various school of thoughts proposing various theories and solutions to resolve the issue to ensure better health for man and the food animals consumed. The environment has been know to play host to various disease agents and the host/carriers are also housed in the environment,creating an unending cycle of infection to diverse hosts. 

 Rats are ubiquitous,with the propensity to carry disease agents in their urine,feces,hair and feet.These creatures could actually be the missing link in the antibiotic resistance saga. 

 Rats presence in poultry houses,farms and pet homes result in feed/water contamination with urine/feces resulting in salmonellosis,which the farmer responds to using antibiotics. When the source of infection is not removed, there will be a continuous cycle of infection-reinfection and treatment with various antibiotics .

  The threat of rats to health of man and animals is real and must be properly understood to ensure the necessary strategy is incorporated. A recent study by scientist in the University of Colombia, has revealed the risk that rats pose:Rats can absorb disease agents from their local environment and spread them, according to a University of British Colombia new study. The results also indicate that the threat rats pose to the health of poultry and humans has been underestimated.

Researchers studied the feces of rats caught at an Abbotsford, B.C. poultry farm, and discovered they all carried avian pathogenic E. coli, a bacteria with the ability to cause disease in chickens and potentially humans. More than one quarter of the rats were carrying multi-drug resistant strains of the bacteria. 

The findings support lead author Chelsea Himsworth's theory that rats act as a "pathogen sponge," soaking up bacteria from their environment. If rats can absorb pathogenic E. coli, then they could potentially be a source of all sorts of other pathogens that we have not anticipated," said Himsworth, assistant professor in the UBC School of Population and Public Health and leader of the Vancouver Rat Project, a group aiming to address the knowledge gap about the health threats associated with rats. 

 Himsworth was surprised to find that the E. coli strains carried by the farm rats were very similar to those found in chickens, and totally different from E. coli strains found in urban rats. Basically, the rural rat gut looked like the poultry gut, and nothing like the urban rat gut . 

 This latest study follows previous research by Himsworth that found human pathogens, including MRSA (methicillin-resistant Staphylococcus aureus) and C. difficile, in the feces of rats in Vancouver's Downtown Eastside. 

 Rat infestations ought to be taken seriously," said Himsworth. "They need to be tackled with an educated, informed approach in collaboration with scientists and pest control professionals. There should be the development of municipal programs for managing rat infestations and rat-related issues.

Cells from cow knee joints used to grow new cartilage tissue in laboratory.

An effort to develop a method for cartilage tissue engineering, researchers have successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive to growing healthy cartilage tissue, the findings could help lead to a new treatment cure for osteoarthritis using stem cell-based tissue engineering, a new report suggests. In an effort to develop a method for cartilage tissue engineering, researchers at Umeå University in Sweden successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive to growing healthy cartilage tissue, the findings could help lead to a new treatment cure for osteoarthritis using stem cell-based tissue engineering. This is according to a doctoral dissertation at Umeå University. Tissue engineering provides a possible solution to osteoarthritis. In their experiments, the researchers at Umeå University made findings that provided useful information for efforts to develop new methods to produce cartilage-like "neotissues" in a laboratory environment. In the engineering process, the cells, the signaling molecules and the scaffold, i.e. artificial support material, are combined to regenerate tissue at the damaged site in the joint. The process is difficult and much of what constitutes suitable growth factors and a mechanical loading environment is still unknown. Today, there is a huge variety of available synthetic and natural scaffolds. It is also unclear whether stem cells or primary cells are best suited. Using primary bovine chondrocytes, i.e. cartilage cells from cows, the researchers improved methods to grow cartilage tissue in a laboratory environment, producing tissue similar to tissue normally present in the human joints. In future, these results may help the development of neocartilage production for actual cartilage repair. For this, stem cells could be grown to provide unlimited amount of material for tissue engineering. However, more research is needed to improve the tissue quality and make it more structurally similar to the hyaline cartilage found in the human body. source; science daily.

HANDLING THE RAT MENACE..

. Rats have been linked to the spread of a lot of disease ,some are fatal while others can be treated.The best way to stay safe is by rodent control.The health risk posed by rats affects man, poultry,dogs and some other animals. Diseases occur as a result of interaction between hosts, agent and environment.Rats are no different from all other carriers,in this sense hence environment influences the infection and risk/rate of exposure. Living in a dirty,unkempt environment increases the chances of infection and consequent spread of infection.Rats are know to thrive where there is food and water, and most rats can eat anything. Living in close quarters with dogs, poultry and horses increases risk of infection.Living in highly populated environment surrounded by filth also poses risk of infection.Rats find their way to food industry and food processing plants posing a risk of food contamination from source. Rats are everywhere causing diseases by contamination through urine,feces, hair,and feet. Rats basically transfer these disease agents by contamination of feed,food,water,toys and clothing.The best way to avoid any disease is by proper pest control and maintenance of clean environment.The following are steps to keeps rats out;1) Use of rat traps 2) keep houses/farms rodent proof; by removing unfinished food, cover bins and keep them far away from homes. 3) rat adhesive boards 4) baits 5)proper waste management. 6) rat-proof your doors,windows in farms,homes and factory. Rats cause food wastage resulting in economic losses,when a food is contaminated by urine or feces,throw away immediately. If you suspect your pets toy is contaminated with rat urine throw away,same with clothing or any other contaminated material. Stay safe # avoid rat bites # dont eat rats # keep environment clean.

MEAT SAFETY.

A simple, rapid test to help ensure safer meat. Scientists now report a simple method that uses nanotubes to quickly detect spoilage. It could help make sure meats are safe when they hit store shelves. Transporting meats and seafood from the farm or sea to the market while they're still fresh is a high priority. But telling whether a product has gone bad isn't a simple process. 

Current strategies for measuring freshness can be highly sensitive to spoilage but require bulky, slow equipment, which prevents real-time analysis. Some newer methods designed to speed up the testing process have fallen short in sensitivity.

 Yanke Che and colleagues wanted to develop one simple test that could deliver both rapid and sensitive results. The researchers turned to highly fluorescent, hollow nanotubes that grow dim when they react with compounds given off by meat as it decomposes.

 To test the nanotubes, the team sealed commercial samples -- 1 gram each -- of pork, beef, chicken, fish and shrimp in containers for up to four days. When they exposed the portable system to a teaspoon of vapor emitted by the samples, it reacted in under an hour, fast enough to serve as a real-time measure of freshness. The researchers also found that if the tubes' glow dulled by more than 10 percent, this meant a sample was spoiled. Story source;American Chemical Society.
