SAN DIEGO (CNS) - Authorities Tuesday reached out to the public for help in identifying and locating a gunman who fatally shot a 35-year-old man in the Grantville area nearly five months ago. Officers responding to reports of gunfire shortly after 2:50 a.m. on May 21 found Mario ``Tony'' Bullard lying on a street in the 6200 block of Holabird Street suffering from at least one gunshot wound, according to San Diego police.Paramedics responded, but Bullard was pronounced dead at the scene. RELATED: Victim in deadly Grantville shooting identifiedThe suspect was spotted running westbound on Vandever Avenue toward Mission Gorge Road after the shooting. He was described as a roughly 5-foot-6 white man who was last seen wearing a black hooded sweatshirt with a white logo on the front, black pants and carrying a backpack. Anyone with information about the suspect or the shooting was asked to call San Diego County Crime Stoppers at 888-580-8477. Tipsters can remain anonymous and could be eligible for a reward of up to ,000. 1040

SAN DIEGO (CNS) - Initial results are expected in the next few days on previously untested rape evidence kits that will help identify offenders who may potentially be linked to other sexual assaults, San Diego County District Attorney Summer Stephan announced Tuesday.Earlier this year, the District Attorney's Office, working with the San Diego County Sheriff's Department, contracted with a private lab, Bode Cellmark Forensics in Lorton, Virginia, to test about 1,000 untested sexual assault kits. So far, 350 rape kits have been sent to the lab for testing, Stephan said.The county's top prosecutor said reducing the backlog of untested sexual assault kits has been a top priority of hers since she took office last July. With the support of San Diego County's chief administrative officer, officials identified about million to go toward the effort of expedited 877

SAN DIEGO (CNS) - An international team of scientists, led by biologists at the University of California San Diego, has synthetically engineered mosquitoes that halt the transmission of the dengue virus, the university announced Thursday.Scientists at UC San Diego Associate Professor Omar Akbari's lab worked with Vanderbilt University Medical Center to identify a human antibody for dengue suppression. The broad-spectrum antibody stops the transmission of all four known types of the fever, compared to previous experiments, which have been able to limit single strains.The team then designed the antibody "cargo" to be synthetically expressed in the dengue-spreading Aedes aegypti mosquitoes.RELATED: UC San Diego study finds solutions for loneliness"Once the female mosquito takes in blood, the antibody is activated and expressed -- that's the trigger," Akbari said. "The antibody is able to hinder the replication of the virus and prevent its dissemination throughout the mosquito, which then prevents its transmission to humans. It's a powerful approach."Akbari works in the Division of Biological Sciences and is a member of the Tata Institute for Genetics and Society.These lab-engineers mosquitoes could be paired with a dissemination system, making it capable of spreading the antibody throughout wild disease- transmitting mosquitoes, Akbari said.Dengue fever is a virus that poses a severe risk to children and older adults in tropical regions in Asia and Latin America. There are an estimated 390 million infections every year, around 500,000 of which lead to Severe Dengue, and 25,000 people die of the disease every year.RELATED: UCSD Health, San Diego Zoo Safari Park team up to save gorilla's eyesightThe Pan American Health Organization recently reported the highest number of dengue cases ever recorded in the Americas. Infecting those with compromised immune systems, dengue victims suffer flu-like symptoms, including severe fevers and rashes. Serious cases can include life-threatening bleeding. No specific treatment exists and thus, prevention and control depend on measures that stop the spread of the virus.This development could go a long way toward limiting the disease's transmission."It is fascinating that we now can transfer genes from the human immune system to confer immunity to mosquitoes," said coauthor of the paper, Dr. James Crowe, Jr., director of the Vanderbilt Vaccine Center at Vanderbilt University Medical Center in Nashville, Tenn. "This work opens up a whole new field of biotechnology possibilities to interrupt mosquito-borne diseases of man."Akbari's lab is now in the early stages of testing methods to simultaneously neutralize mosquitoes against dengue and a suite of other viruses such as Zika, yellow fever and chikungunya. 2789

SAN DIEGO (CNS) - A San Diego molecular diagnostic company announced Thursday it has been awarded a contract from the U.S. Department of Health and Human Services to fund development of its coronavirus diagnostic test, which the company says would provide results in about 30 minutes.Mesa Biotech Inc. will receive both 1,330 in funding and "technical expertise" from the HHS's Biomedical Advanced Research and Development Authority -- or BARDA -- to complete developmental work needed to obtain Emergency Use Authorization from the U.S. Food and Drug Administration.The FDA's emergency authorizations fast-track unapproved medical products for use during a public health emergency.Mesa says its Accula SARS-CoV-2 test utilizes throat swabs to detect SARS-CoV-2, the virus that causes COVID-19."As the coronavirus situation escalates and the demand for testing far exceeds capacity, we are encouraged by the support of HHS in the development of our Accula SARS-CoV-2 Test," said Hong Cai, Mesa Biotech's co- founder and CEO."Our test, which was developed to enable rapid responses to global pandemics, will significantly compress the sample-to-result timeframe with a laboratory-quality test at the point-of-care," Cai said. "This accelerated response will enable health care providers to rapidly screen, isolate, treat or dismiss potential carriers of the virus."In the past week, three companies with local laboratories received emergency approval from the FDA to supply COVID-19 detection tests, including Hologic Inc. and Quidel Corp. in San Diego, and Thermo Fisher Scientific Inc. in Carlsbad.Mesa Biotech's diagnostic test is one of four to receive funding from BARDA, according to the agency."Diagnostics are a critical need in the overall strategy to fight this newest global public health threat," BARDA Director Rick A. Bright said. "We need increased testing capacity in the U.S. to rapidly identify, isolate and treat those infected with COVID-19 in order to limit transmission of the virus, and we need those tests as close to the patients as possible."Currently, no FDA-approved diagnostics, vaccines or treatments for COVID-19 are available. 2168

SAN DIEGO (CNS) - A western harvest mouse found in Escondido tested positive for the potentially deadly hantavirus, San Diego County Vector Control officials announced Friday.The mouse was found during routine monitoring of the area. Since January, Vector Control has collected multiple mice that have tested positive for the virus in areas of north and east county, including Julian, Fallbrook, Bonsall, Boulevard, 4S Ranch, Warner Springs and Potrero.With each instance, county officials have reminded residents to avoid sweeping or vacuuming rodent droppings, which can push the virus into the air. Instead, residents are advised to use so-called "wet cleaning" methods like a diluted bleach spray, disinfectants or a sponge and a mop to clean up wild rodent matter like urine, feces and saliva. Cleansed areas should also remain well-ventilated to ensure the virus does not linger.RELATED:Three cases of tuberculosis reported in San Diego CountyThird patient dies of flu this season in San DiegoGoogle is collecting health data on millions of AmericansHantavirus is not uncommon in San Diego County's rural and undeveloped areas, but residents can avoid exposure by keeping rodents out of their homes, sheds and garages, according to Vector Control. Wild mice, in particular, are the virus' main carriers.There is no cure or vaccine for hantavirus, which can cause deadly infections. According to the Centers for Disease Control and Prevention, symptoms of infection can include fever, aches in the large muscle groups, dizziness, digestive issues and abdominal pain.Residents can prevent exposure to hantavirus by sealing holes larger than a dime and quickly disposing of rodent debris in homes and adjacent structures.The county's Department of Environmental Health can be reached at 858- 694-2888 for more information about avoiding hantavirus exposure and infection. In addition, residents can find more information on the virus here. 1950
