Surveillance and improved control of American foulbrood in Saskatchewan honey bees through the detection of Paenibacillus larvae spores in pooled, extracted honey
… bacterial disease, American foulbrood (AFB). The infectious endospores (spores) of the causative agent, Paenibacillus larvae, are incredibly resilient to environmental extremes and are impervious to antimicrobials licensed for use against AFB (1–3). Consequently, non-curative antibiotic …

Contributing factors to child stunting in Guatemala: A systems analysis focused on enteric disease transmission and mycotoxin exposure
… correlated with height-for-age, 2) aflatoxin B (AFB) exposure is correlated with height-for-age, and 3) AFB exposure is correlated with EED. A network analysis was conducted on data from the US Agency for International Development (USAID) collected in 2012 to identify trends in a height-for-age …

Anticarcinogenic, Antitumor, and Antifungal Properties of Allium Sativum (Garlic)
… TA100 induced by either aflatoxin B1 (AFB^ or benzo[a]pyrene (B[a]P). The garlic compounds were shown to inhibit the binding of [<sup>3</sup>H]AFB<sub>1</sub> to calf thymus DNA and the formation of specific AFB<sub>1-</sub>DNA adducts. These effects on mutagenesis and DNA binding …

Military Base Closure and Community Transformation: The Case of England Air Force Base in Central Louisiana
Closing England Air Force Base (AFB) emerged as a possibility following the first Base Realignment and Closure (BRAC) round in 1988. The central Louisiana community responded with a dual strategy: defense, implemented by a highly visible group of mostly elected officials who fought to save the …

Comparison of Potential Bioavailable Organic Carbon and Microbial Characterization of Two Carbon Amended Sites
… plots to show microbial diversity. At Tinker AFB, results from the t-test showed that the PBOC concentrations from the ERB samples were statistically significantly greater than the samples without treatment (95% confidence; p-value = 0.018). For Dover AFB, results from the ANOVA with Tukey's …

Evaluation of a Paratuberculosis Quantitative Polymerase Chain Reaction Assay with Microscopic Correlation
… 0-4 based on the quantity of acid fast bacteria (AFB). Digital microscopy and morphometric software were used to compute an acid fast bacteria area index (AFBAI) to evaluate a more precise correlation with the qPCR results. The quantity of AFB in tissue slides showed medium to strong correlation …

The toxicity and mutagenicity of the aflatoxin B₁ formamidopyrimidine DNA adduct
Aflatoxin B1 (AFB1) is a fungal metabolite that contaminates the food supply in certain areas of the world. It is produced by Aspergillusflavus and related fungi that grow on improperly stored foods such as corn, rice, and peanuts. Epidemiological studies have shown a correlation between exposure …

Diagnostic yield of tuberculosis investigations on bone marrow biopsy samples in HIV positive patients at Groote Schuur Hospital
Background: Acid fast bacilli (AFB) staining on bone marrow samples has low sensitivity for diagnosing HIVassociated tuberculosis and Tuberculosis (TB) culture results may be delayed. The GeneXpert® MTB/RIF Ultra assay may provide a more sensitive diagnostic test on bone marrow biopsy samples. …

A new mouse model to probe the role of aflatoxin B₁ in liver carcinogenesis
… the thesis, a kinetic profile was generated of AFB 1-DNA adduct formation and removal. In the second part of the work, adduct levels and specific DNA damage patterns of males and females were compared (males are generally more sensitive than females to this and other toxins). Third, nursing …

Quantification of benzo[a]pyrene-diol-epoxide adducts by laser-induced fluorescence spectroscopy
… shown to form adducts with BPDE, aflatoxin B1 (AFB,) and nitrosomethylurea (NMU) in TK6 cells grown in vitro. Histone adducts of AFB 1 , NMU, and BPDE were shown to be stable over 5 cell divisions.

Variation in peach fruit susceptibility to Monilinia laxa and gene expression
… from the 6thto the 12th week after full bloom (AFB) inoculated with M. laxa or mock-inoculated. The data suggest a critical change in the expression level of the phenylpropanoid pathway from the 7th to the 8th week AFB; such change could be directly physiologically associated to the peach growth …

Bird Strike Risk Assessment for United States Air Force Airfields and Aircraft
… airfields with higher bird strike risks. Howard AFB, Panama, had a higher number and rate of bird strikes, and greater odds for a damaging bird strike than other airfields analyzed. This study allows recommendations for improving reporting of bird strikes and data management. Results will enable …
