Newly recognized focus of La Crosse encephalitis in Tennessee. (1/75)

La Crosse virus is a mosquito-borne arbovirus that causes encephalitis in children. Only nine cases were reported in Tennessee during the 33-year period from 1964-1996. We investigated a cluster of La Crosse encephalitis cases in eastern Tennessee in 1997. Medical records of all suspected cases of La Crosse virus infection at a pediatric referral hospital were reviewed, and surveillance was enhanced in the region. Previous unreported cases were identified by surveying 20 hospitals in the surrounding 16 counties. Mosquito eggs were collected from five sites. Ten cases of La Crosse encephalitis were serologically confirmed. None of the patients had been discharged from hospitals in the region with diagnosed La Crosse encephalitis in the preceding 5 years. Aedes triseriatus and Aedes albopictus were collected at the case sites; none of the mosquitos had detectable La Crosse virus. This cluster may represent an extension of a recently identified endemic focus of La Crosse virus infection in West Virginia.  (+info)

Human MxA protein protects mice lacking a functional alpha/beta interferon system against La crosse virus and other lethal viral infections. (2/75)

The human MxA protein is part of the antiviral state induced by alpha/beta interferon (IFN-alpha/beta). MxA inhibits the multiplication of several RNA viruses in cell culture. However, its antiviral potential in vivo has not yet been fully explored. We have generated MxA-transgenic mice that lack a functional IFN system by crossing MxA-transgenic mice constitutively expressing MxA with genetically targeted (knockout) mice lacking the beta subunit of the IFN-alpha/beta receptor (IFNAR-1(-/-) mice). These mice are an ideal animal model to investigate the unique antiviral activity of human MxA in vivo, because they are unable to express other IFN-induced proteins. Here, we show that MxA confers resistance to Thogoto virus, La Crosse virus, and Semliki Forest virus. No Thogoto virus progeny was detectable in MxA-transgenic mice, indicating an efficient block of virus replication at the primary site of infection. In the case of La Crosse virus, MxA restricted invasion of the central nervous system. In contrast, Semliki Forest virus multiplication in the brain was detectable in both MxA-expressing and nonexpressing IFNAR-1(-/-) mice. However, viral titers were clearly reduced in MxA-transgenic mice. Our results demonstrate that MxA does not need the help of other IFN-induced proteins for activity but is a powerful antiviral agent on its own. Moreover, the results suggest that MxA may protect humans from potential fatal infections by La Crosse virus and other viral pathogens.  (+info)

Bunyavirus superinfection and segment reassortment in transovarially infected mosquitoes. (3/75)

Rapid evolution of bunyaviruses may occur by RNA segment reassortment between closely related viruses. Reassortment between viruses occurs in dually infected mosquitoes when two different viruses are simultaneously ingested or when the second virus is ingested within 2 days of the first virus. By 3 days after oral infection, interference to superinfection occurs, thus limiting the potential for evolution. Aedes triseriatus mosquitoes can also be transovarially infected (TI+) with LaCrosse (LAC) virus. In these studies, the potential for oral superinfection of TI+ mosquitoes was assessed. Approximately 20% of mosquitoes TI+ with either a temperature-sensitive LAC virus or wild-type (wt) LAC virus became superinfected by ingesting blood meals containing wt LAC or snowshoe hare (SSH) viruses. LAC virus TI+ mosquitoes superinfected with SSH virus were detected by blot hybridization or RT-PCR. Viruses from these mosquitoes were plaque purified and genotyped using RT-PCR. Reassortant genomes were detected in 2.3% of the viruses genotyped, and 4.0% of the genomes tested were diploid for one genome segment.  (+info)

Detection of anti-arboviral immunoglobulin G by using a monoclonal antibody-based capture enzyme-linked immunosorbent assay. (4/75)

Monoclonal antibody (MAb)-based capture enzyme-linked immunosorbent assays (ELISAs) for the detection of anti-arboviral immunoglobulin G (IgG ELISAs) were developed for a comprehensive array of medically important arboviruses from the Alphavirus, Flavivirus, and Bunyavirus genera. Tests were optimized and standardized so that maximum homology could be maintained among working parameters for the different viral agents, enabling a wide range of viruses to be easily tested for at one time. MAbs were screened for suitability as capture vehicles for antigens from the three genera. The final test configuration utilized group-reactive MAbs eastern equine encephalitis virus 1A4B-6, dengue 2 virus 4G2, and La Crosse encephalitis virus 10G5.4 to capture the specific inactivated viral antigens. Serum IgG was detected by using alkaline phosphatase-conjugated anti-human IgG (Fc portion). A dilution of 1:400 was chosen as the universal screening serum dilution, with endpoint titrations of serum samples testing positive eliminating occasional false-positive results. IgG ELISA results correlated with those of the standard plaque-reduction neutralization assays. As expected, some test cross-reactivity was encountered within the individual genera, and tests were interpreted within the context of these reactions. The tests were standardized for laboratory diagnosis of arboviral infections, with the intent that they be used in tandem with the corresponding IgM antibody-capture ELISAs.  (+info)

La Crosse encephalitis presenting like herpes simplex encephalitis in an immunocompromised adult. (5/75)

The diagnosis of the precise cause of viral encephalitis can be difficult, hampered by the nonspecific presentation, the number of etiologic viruses, and limited culture and serologic diagnostic methods. Because herpes simplex encephalitis (HSE) can be neurologically devastating and is treatable, timely diagnosis is important. We report an immunocompromised adult with encephalitis clinically consistent with HSE who had serology consistent with recent La Crosse encephalitis (LAC).  (+info)

Serological survey and active surveillance for La Crosse virus infections among children in Tennessee. (6/75)

In 1998 and 1999, we performed a serosurvey and active surveillance for La Crosse encephalitis at a children's hospital in eastern Tennessee. Fifteen cases of La Crosse encephalitis were confirmed. Only 5 (0.5%) of 1000 serum samples being tested at the state laboratory for other diseases had evidence of antibodies to La Crosse virus. These findings suggest that La Crosse virus is newly endemic to eastern Tennessee.  (+info)

Hantavirus nucleocapsid protein is expressed as a membrane-associated protein in the perinuclear region. (7/75)

Black Creek Canal virus (BCCV) is a New World hantavirus which is associated with hantavirus pulmonary syndrome. We have examined the site of expression of the BCCV nucleocapsid protein (NBCCV) in the absence of BCCV glycoproteins and found that the majority of the protein is localized to the Golgi region. Immunofluorescence analysis of BHK21 cells expressing the NBCCV and La Crosse virus nucleocapsid protein (NLACV) showed different intracellular localization patterns of these proteins within the same cell: NLACV is cytoplasmic, whereas NBCCV is perinuclear. NBCCV was found to be colocalized with alpha-mannosidase II, a marker for the Golgi complex. Also, NBCCV was found to be associated with microsomal membranes following cell fractionation. Sedimentation analysis in density gradients revealed that the membrane association of NBCCV is sensitive to treatments with high-salt and high-pH solutions, which indicates that NBCCV is a peripheral membrane protein. Analysis of NBCCV truncation mutants revealed that the 141-amino-acid C-terminal portion of this protein was capable of targeting green fluorescent protein to the perinuclear region. The difference in the intracellular localization between the NBCCV and NLACV proteins suggests that the mechanisms involved in the morphogenesis of New World hantaviruses are distinct from that documented for other members of the Bunyaviridae family.  (+info)

Expression of human MxA protein in mosquito cells interferes with LaCrosse virus replication. (8/75)

Human MxA protein inhibits LaCrosse virus (LAC virus; family Bunyaviridae) replication in vertebrate cells and MxA-transgenic mice. LAC virus is transmitted to humans by Aedes triseriatus mosquitoes. In this report, we have shown that transfected mosquito cells expressing the human MxA cDNA are resistant to LAC virus but permissive for Sindbis virus (family Togaviridae) infection.  (+info)

Abstract La Crosse (LAC) virus was isolated from 3 suspensions of Aedes triseriatus larvae and from 1 suspension of male mosquitoes reared from larvae collected from basal tree-holes in Wisconsin during March, April, May, and June of 1973. Isolations of this virus were also obtained from 5 suspensions of A. triseriatus larvae and 4 suspensions of male mosquitoes originating from old automobile tires. Virus transmission to suckling mice was accomplished by female A. triseriatus reared from larvae collected from the tires. Only two tree-holes and the tires yielded LAC virus-infected larvae and adults. The minimum field infection rate (MFIR) for these tree-holes and the tires, based on one infected larva per pool, was 1/110 larvae from the tree-holes and 1/20 larvae from the tires. The MFIR for adults was 1/41 male mosquitoes originating from one of the tree-holes and 1/27 for male mosquitoes originating from the tires. The MFIR for female mosquitoes reared from larvae collected from the tires was 1/110.
La Crosse virus (LACV) (genus Orthobunyavirus, family Peribunyaviridae) is a mosquito-borne virus that causes pediatric encephalitis and accounts for 50-150 human cases annually in the USA. Human cases occur primarily in the Midwest and Appalachian regions whereas documented human cases occur very rarely in the northeastern USA. Following detection of a LACV isolate from a field-collected mosquito in Connecticut during 2005, we evaluated the prevalence of LACV infection in local mosquito populations and genetically characterized virus isolates to determine whether the virus is maintained focally in this region. During 2018, we detected LACV in multiple species of mosquitoes, including those not previously associated with the virus. We also evaluated the phylogenetic relationship of LACV strains isolated from 2005-2018 in Connecticut and found that they formed a genetically homogeneous clade that was most similar to strains from New York State. Our analysis argues for local isolation and long-term
We characterized a La Crosse virus (LACV) isolate from the brain of a child who died of encephalitis-associated complications in eastern Tennessee, USA, during summer 2012. We compared the isolate with LACV sequences from mosquitoes collected near the childs home just after his postmortem diagnosis. In addition, we conducted phylogenetic analyses of these and other sequences derived from LACV strains representing varied temporal, geographic, and ecologic origins. Consistent with historical findings, results of these analyses indicate that a limited range of LACV lineage I genotypes is associated with severe clinical outcomes ...
Abstract The tropisms and development of La Crosse (LAC) virus in stages of transovarially infected Aedes triseriatus were studied with fluorescent antibody (FA) stained dissected organs and titrations of individual arthropods in suckling mice. Viral antigen was detected by FA in 95 of 387 dissected larvae, pupae, and adults. In larvae highest levels of fluorescence were detected in the alimentary tract, followed by ganglia, malpighian tubule, muscle, and other tissues. No specific organs or germ layer-derived tissues appeared to be the sole source of viral replication. Most tissues and organs of A. triseriatus are capable of maintaining LAC virus. Antigen was detected in the identifiable organs immediately upon emergence from the egg. In pupae and adults antigen was detected at high levels in foregut, gonadal and associated tissues, and in salivary glands, which would indicate females could be infective upon emergence. Virus was isolated from all arthropod stages, in 32 of 130 individuals inoculated
La Crosse encephalitis virus (LACV) is transmitted to humans by the bite of an infected mosquito. Most cases of LACV disease occur in the upper Midwestern and mid-Atlantic and southeastern states (see map).. Many people infected with LACV have no apparent symptoms. Among people who become ill, initial symptoms include fever, headache, nausea, vomiting, and tiredness. Some of those who become ill develop severe neuroinvasive disease (disease that affects the nervous system). Severe LACV disease often involves encephalitis (an inflammation of the brain) and can include seizures, coma, and paralysis. Severe disease occurs most often in children under the age of 16. In rare cases, long-term disability or death can result from La Crosse encephalitis.. There is no specific treatment for LACV infection-- care is based on symptoms. If you or a family member have symptoms of severe LACV disease or any symptoms causing you concern, consult a healthcare provider for proper diagnosis.. The best way to ...

By Terry Rindfleisch, La Crosse Tribune, Wis. Jul. 8--Sexually transmitted diseases continue to be a public health concern in La Crosse County. For the past several years, STDs have been on the rise, and that didnt change much last year, according to the 2007 La Crosse County Health Department annual report. The number of gonorrhea cases in the county more than doubled, from 27 in 2006 to 62 in 2007. The first episode of genital herpes also increased significantly from 74 in 2006 to 108 last year. The good news is the number of chlamydia cases dropped for the first time in several years from 355 to 335, but Doug Mormann said the number is still too high. STDs continue to be a problem, but its not a unique problem to our county, said Mormann, director of the La Crosse County Health Department.

Scientists have determined that La Crosse virus (LACV), which can cause inflammation of the brain, or encephalitis, in children, affects brain cells differently depending on their developmental stage. Neurons-the primary brain cells of the central nervous system-evolve from neural stem cells and during development commit to becoming neurons. A new National Institutes of Health study shows that uncommitted neural stems cells generally survive LACV infection, while LACV often kills neurons. The study also shows that neurons infected by LACV can be rescued by interferon, a powerful antiviral protein. The study results appear in the Journal of Neuroinflammation.. LACV is spread by mosquitoes and was first identified in the early 1960s. Most infections in people are mild but the virus sometimes-particularly in children-enters the brain, infects neurons and causes disease ranging from learning and memory difficulties to paralysis, seizures and death. The Centers for Disease Control and Prevention ...
Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by mosquitoes. They can transmit disease without being affected themselves. Nearly 700 million people get a mosquito borne illness each year resulting in greater than one million deaths. Diseases transmitted by mosquitoes include: malaria, dengue, West Nile virus, chikungunya, yellow fever, filariasis, tularemia, dirofilariasis, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, Ross River fever, Barmah Forest fever, La Crosse encephalitis, and Zika fever.[better source needed] The female mosquito of the genus Anopheles carries the malaria parasite (see Plasmodium).

Mosquito-borne diseases are diseases of humans and/or animals caused by bacteria, viruses, or parasites transmitted by mosquitoes. The list of mosquito-borne diseases is long (e.g., malaria, dengue, West Nile virus, Zika virus, chikungunya, yellow fever, filariasis, La Crosse encephalitis, Eastern equine encephalitis, Saint Louis encephalitis, etc.).. According to the World Health Organization, mosquitoes cause millions of deaths every year. Vector control has been an effective tool to control mosquito populations historically and continues today with conventional and updated tools. Integrated mosquito management (IMM) and integrated vector management (IVM) programs and guides have been developed to address the complexities of effective vector control strategies. The IVM approach is to improve the efficacy, cost-effectiveness, ecological soundness and sustainability of disease-vector control.. ...

Summer can be itchy, and not because you were foolish enough to acquire a really bad sunburn or a wool bikini. No, the number one itch-creator in the summer is (ugh!) mosquitoes! Mosquitoes love the warm weather as much as college coeds love spring break. Theyre just about as tenacious, too (the mosquitoes, that is). Although nobody ever invites mosquitoes to an outdoor party, they always tend to show up and wreak havoc. And it can be even worse if they get into your house, because now youre living with the little suckers, which means youre on the menu for breakfast, lunch, and dinner.. But more than just an itchy nuisance, mosquitoes can be a health hazard, as well. These tiny winged creatures spread disease faster than a flu-infested toddler, distributing everything from West Nile Virus to La Crosse encephalitis to malaria. How is that possible? Because mosquitoes become carriers of human-born diseases when they feed off infected people. Even though mosquitoes dont suffer from the ...

Ramirez testified through an interpreter, saying he was outside urinating after a night of drinking when he looked down and saw Gorectke with blood on her face. He tried to put her in his car, but failed. He also said he was sure he didnt come across her outside a church. He leaned her against a wall and gave her his cell phone. He said he didnt call police because he was afraid. His attorney, Ronald Benavides, said in closing arguments that Ramirez didnt want blood in his car and he made the decision to leave because he was drunk. Gruenke told jurors Ramirez was lying. His story doesnt explain her fingerprints in his car, her blood on his jeans, or how his DNA got her lip or how her DNA got on his genitals. Benavides said the brutality of Gorectkes death doesnt mean Ramirez killed her. His DNA was never found on her ear and if he was trying to hide her blood he wouldnt have walked into the La Crescent store with it on his clothes. Gorectkes DNA could have ended up on his genitals when ...

FRIDAY, Aug. 28, 2020 (HealthDay News) -- Breastfeeding mothers are unlikely to transmit the new coronavirus to their babies via their milk, researchers say.. No cases of an infant contracting COVID-19 from breast milk have been documented, but questions about the potential risk remain.. Researchers examined 64 samples of breast milk collected from 18 women across the United States who were infected with the new coronavirus (SARS-CoV-2) that causes COVID-19.. One sample tested positive for coronavirus RNA, but follow-up tests showed that the virus couldnt replicate and therefore, couldnt infect the breastfed infant, according to the study recently published online in the Journal of the American Medical Association.. Detection of viral RNA does not equate to infection. It has to grow and multiply in order to be infectious and we did not find that in any of our samples, said study author Christina Chambers, a professor of pediatrics at the University of California, San Diego. She is also ...
About 15% of people exposed to someone carrying the variant wind up infected, compared with a 10% infection rate associated with the standard COVID-19 coronavirus, according to a report by British public health officials.. But data from the United Kingdom has shown that the new variant doesnt appear to have any resistance against the COVID-19 vaccines being distributed across America, Glatter said.. The new strain has not yet been shown to be more resistant to the Pfizer and Moderna mRNA-based COVID-19 vaccines that have recently been rolled out, along with other vaccine candidates in Phase 3 trials and yet to be granted emergency use authorization, Glatter said.. These mRNA vaccines are engineered to induce the immune system to produce antibodies to multiple areas of the spike protein, he said. The spike protein, found on the outer surface of the virus, is the primary way the virus attaches to cells in the body, he explained. Dr. Ashish Jha, dean of the Brown University School of Public ...

Mosquito-borne diseases occur annually in West Virginia beginning in early spring and peaking in August and September, coinciding with mosquito activity. Arboviral infections, particularly La Crosse encephalitis (LAC) and West Nile virus (WNV), are endemic mosquito-borne diseases identified in West Virginia. In 2016, eight LAC cases and one WNV case were reported in West Virginia. Persons with severe arboviral infections will often have symptoms of encephalitis. Please be vigilant in identifying such cases, and ensure that all hospitalized patients with encephalitis undergo appropriate arboviral disease testing during mosquito season.. The Zika virus disease is reportable to the local health department (LHD) within 24 hours since it is an emerging disease of public health concern. To prevent local and sexual transmission and infections in pregnant women at-risk of having adverse birth outcomes, prompt public health action is needed. In 2016 , 11 Zika virus cases were reported in West Virginia. ...
In the United States, improperly stored tires serve as an excellent breeding habitat for several mosquito species that transmit a number of potentially deadly human and animal diseases. These diseases include La Crosse Encephalitis, St. Louis Encephalitis, Eastern Equine Encephalitis, and, in the past, Dengue and Yellow Fever. The commercial trade in scrap tires is also responsible for the recent introduction and spread of the Asian Tiger Mosquito, Aedes albopictus. We have not yet solved the problem of economic disposal of scrap tires. The EPA estimates 3 billion tires currently litter the landscape of the USA and the pile grows by 300,000 every year. Public health authorities have become obsessed with tire disposal; nearly every state has new laws and new taxes on tire disposal. Unfortunately, these measures lead to a great deal of illegal dumping. When landfills are closed to tires (very frequent at present), the tires get dumped in rural or wilderness areas when nobody is looking. Furtive ...

Lassa virus (LASV) causes deadly hemorrhagic fever disease for which there are no vaccines and limited treatments. LASV-encoded L polymerase is required for viral RNA replication and transcription. The functional domains of L-a large protein of 2218 amino acid residues-are largely undefined, except for the centrally located RNA-dependent RNA polymerase (RdRP) motif. Recent structural and functional analyses of the N-terminal region of the L protein from lymphocytic choriomeningitis virus (LCMV), which is in the same Arenaviridae family as LASV, have identified an endonuclease domain that presumably cleaves the cap structures of host mRNAs in order to initiate viral transcription. Here we present a high-resolution crystal structure of the N-terminal 173-aa region of the LASV L protein (LASV L173) in complex with magnesium ions at 1.72 Å. The structure is highly homologous to other known viral endonucleases of arena- (LCMV NL1), orthomyxo- (influenza virus PA), and bunyaviruses (La Crosse virus ...

In response to #17 by Linn,. If there was more natural variability in the past as shown in MBH98/99, e.g. as the Moberg reconstruction shows, that doesnt necessary lead to the conclusion that climate is more responsive to greenhouse gases (GHGs).. That would only be true, if the climate response was the same for the amount of energy retained by GHGs, as for the incoming energy from sunlight reaching the earth. But part of the suns influence is in the stratosphere, where CO2 (unlike some other GHGs) doesnt play an important role. This leads to changes in Jet Stream position and in general (and specific low) cloud cover, fortifying the solar signal. No matter what (unknown) physical process causes the changes in cloud cover, these changes are observed during a sun cycle. See: http://folk.uio.no/jegill/papers/2002GL015646.pdf. If there was more natural variation in the past millenia, specifically due to solar changes, then that goes at the cost of the GHG/aerosol combination, as both are near ...
