Local Mosquito-Borne Transmission of Zika Virus - Miami-Dade and Broward Counties, Florida, June-August 2016.

During the first 6 months of 2016, large outbreaks of Zika virus disease caused by local mosquito-borne transmission occurred in Puerto Rico and other U.S. territories, but local mosquito-borne transmission was not identified in the continental United States (1,2). As of July 22, 2016, the Florida Department of Health had identified 321 Zika virus disease cases among Florida residents and visitors, all occurring in either travelers from other countries or territories with ongoing Zika virus transmission or sexual contacts of recent travelers.* During standard case investigation of persons with…

Ecological niche modeling of mosquito vectors of West Nile virus in St. John's County, Florida, USA.

BACKGROUND: The lack of available vaccines and consistent sporadic transmission of WNV justify the need for mosquito vector control and prediction of their geographic distribution. However, the distribution of WNV transmission is dependent on the mosquito vector and the ecological requirements, which vary from one place to another. METHODS: Presence/density data of two WNV mosquito vectors, Culex nigripalpus and Cx. quinquefasciatus, was extracted within 5 km buffer zones around seropositive records of sentinel chickens in order to delineate their predicting variables and model the habitat su

Филогеография эдеса аегипти (желтая лихорадка комаров) в Южной Флориде: данные mtDNA для дисперсии с помощью человека.

Инвазивный вектор денге Aedes aegypti сохраняется на протяжении более 200 лет в Южной Флориде в Соединенных Штатах. Мы проверили гипотезы о том, что ландшафт Флориды создает дисперсионные барьеры и коридоры, а также осаждённые человеком структуры рассеивания на большие расстояния. Мы оценили филогеографию 362 человек с восточного и западного побережья Флориды с 760-бр (418- и 342-бп фрагментов ND5 и ND4 соответственно) митохондриальной последовательности. Население этих двух берегов существенно не различалось, что свидетельствует о том, что ограниченная урбанизация в центральной части Флориды

We tested the hypotheses that Florida's landscape creates dispersal barriers and corridors and that long-distance human-aided dispersal structures populations of Ae. aegypti. We evaluated the phylogeography of 362 individuals from Florida's East and …

Chemical analysis of an immunoenhancing water-soluble polysaccharide of an edible mushroom, Pleurotus florida blue variant.

An immunoenhancing polysaccharide isolated from the aqueous extract of the fruit bodies of the mushroom, Pleurotus florida blue variant, was found to consist of d-glucose and d-galactose in a molar ratio of nearly 5:1. On the basis of sugar analysis, methylation analysis, periodate oxidation, Smith degradation, and NMR studies ((1)H, (13)C, DEPT-135, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC), the structure of the repeating unit of the polysaccharide was established as: →6)-β-D-Glcp-(1→3)-α-D-glcp-(1→[6)-β-D-Glcp-(1]3→ α-D=Glcp. The molecule activated macrophages, splenocytes, and thymocyt…

Potential effects of electronic laboratory reporting on improving timeliness of infectious disease notification--Florida, 2002-2006.

Electronic laboratory reporting (ELR) potentially can improve the timeliness of notifiable disease case reporting and subsequent disease control activities, but the extent of this improvement and the resulting effects on the workload of state or local surveillance teams are unknown. To estimate those effects, investigators from the Florida Department of Health (FDOH) evaluated the timeliness of reporting for four notifiable diseases of varying incubation periods: salmonellosis, shigellosis, meningococcal disease, and hepatitis A. Investigators then calculated the potential improvement expected…

Outbreak bias in illness reporting and case confirmation in ciguatera fish poisoning surveillance in south Florida.

OBJECTIVE: Ciguatera fish poisoning is a potentially life-threatening disease caused by eating coral reef fish contaminated with ciguatoxins and is the most common marine poisoning. However, existing surveillance systems capture few cases. To improve regional ciguatera surveillance in South Florida, this study compared ciguatera illnesses in the Florida Poison Information Center-Miami (FPICM) call database to ciguatera cases in the Florida Department of Health (FDOH) disease surveillance systems. METHODS: Univariate and multivariate logistic regression were used to identify predictors of when…

Abnormal bone composition in female juvenile American alligators from a pesticide-polluted lake (Lake Apopka, Florida).

Reproductive disorders have been found in pesticide-exposed alligators living in Lake Apopka, Florida (USA). These disorders have been hypothesized to be caused by exposure to endocrine- disruptive estrogen-like contaminants. The aim of this study was to expand our analysis beyond previous studies by investigating whether bone tissue, known to be affected by sex steroid hormones, is a potential target of endocrine disruptors. Long bones from 16 juvenile female alligators from Lake Apopka (pesticide-contaminated lake) and Lake Woodruff (control lake) were evaluated by peripheral quantitative co…

Conception rates after artificial insemination or embryo transfer in lactating dairy cows during summer in Florida.

The objective was to compare conception rates to embryo transfer relative to AI, during summer heat stress, in lactating dairy cows. Holstein cows (n = 180; 50 to 120 d postpartum) were allocated randomly to 1 of 3 groups: artificial insemination (AI, n = 84), embryo transfer using either embryos collected from superovulated donors (ET-DON, n = 48), or embryos produced in vitro (ET-IVF, n = 48). Embryos from superovulated donors were frozen in 10% glycerol and were rehydrated in a 3-step procedure, in decreasing concentrations of glycerol in a sucrose medium before transfer. Embryos produced i

Florida's Opioid Prescribing Law Associated With Halt in Declining Opioid Fills Among New Users.

INTRODUCTION: The opioid crisis has increased morbidity and mortality in the U.S. In response, states have implemented policies targeting excessive opioid prescribing. Florida's House Bill 21, enacted in 2018, required prescribers to participate in prescription drug monitoring programs and limited acute opioid prescriptions to a 3-7-day supply. METHODS: This study used a quasi-experimental interrupted time-series analysis of Florida Medicaid claims from 2016 to 2019 to evaluate whether House Bill 21 was associated with changes in opioid prescribing. The study included 2,813,775 Medicaid Manag…

Prevalence of N,N-Dimethylpentylone in forensic toxicology casework: A retrospective study and trends in the state of Florida.

Substituted cathinones (SCs) have been more prominent in the state of Florida than in many other jurisdictions across the United States. Since mid-2021, N,N-Dimethylpentylone (DMP) has been the most encountered cathinone in forensic casework, though its prevalence has varied across the state. Given this prevalence and variability, developing a more comprehensive understanding of DMP became increasingly important. The aim of this study was to assess the prevalence of DMP in Florida from late 2021 through 2024 and to characterize its pharmacologic and toxicologic effects observed in authentic ca…
