The effects of edible chitosan coating (0.1%, 0.3%, 0.5% and 0.75% w/v) on the changes in quality, respiration rate, total phenolic content anthocyanin postharvest sweet cherry (Prunus avium L.) at 10 °C were investigated. activities superoxide dismutase (SOD), catalase (CAT) ascorbate peroxidase (APX) also determined. result showed that treatments effective delaying evolution parameters relate...

Johne's disease, caused by infection with Mycobacterium avium subsp. paratuberculosis, causes significant economic losses to the livestock farming industry. Improved investigative and diagnostic tools-necessary to understand disease processes and to identify subclinical infection-are much sought after. Here, we describe the production of single-chain antibodies with defined specificity for M. a...

The aim of this study was to use the microtitre alamarBlue assay to investigate and compare the antimycobacterial potential of the lantibiotics nisin and lacticin 3147 against a representative cohort of clinically significant mycobacteria, i.e. Mycobacterium tuberculosis H37Ra, Mycobacterium avium subsp. paratuberculosis (MAP) ATCC 19698 and Mycobacterium kansasii CIT11/06. Lacticin 3147 displa...

We measured seasonal changes in the prevalence of haematozoa (Leucocytozoon fringillinarum, Haemoproteus fringillae, and Trypanosoma avium) in free-ranging White-winged Crossbills, Loxia leucoptera, over 1.5 year in Fairbanks, Alaska, USA. This prevalence was low during early winter. L. fringillinarum prevalence increased in late winter/early spring, in the absence of vectors, suggesting relaps...

Currently, paratuberculosis vaccines are comprised of crude whole-cell preparations of Mycobacterium avium subsp. paratuberculosis. Although effective in reducing clinical disease and fecal shedding, these vaccines have severe disadvantages as well, including seroconversion of vaccinated animals and granulomatous lesions at the site of vaccination. DNA vaccines can offer an alternative approach...

BACKGROUND AND OBJECTIVES Diagnosis of avian tuberculosis by conventional culture method is still considered as the "gold standard" technique. The main objective of this study was to compare growth of Mycobacterium avium subsp. avium on four specific Mycobacterial cultures such as glycerinated Lowenstein-Jensen medium, pyruvate-enriched Lowenstein-Jensen medium, mycobactin J-supplemented Herrol...

Studies seeking Mycobacterium avium subsp. paratuberculosis in Crohn's disease by PCR have generated inconsistent findings. As an alternative, microscopy offers a number of advantages, including direct visualization of organisms in tissue. Experimental infections have demonstrated that M. avium organisms can be seen by both acid-fast staining and species-specific in situ hybridization, but beca...

The purpose of the present study was to investigate the occurrence of Mycobacterium avium subsp. avium in naturally infected lofts of domestic pigeons, clinical signs, necropsy findings, differential susceptibility of male and female pigeons to infection and disease and vertical transmission. Eighty out of more than 600 pigeons were selected based on their clinical signs and poor health conditi...

Mycobacterium avium is an intracellular organism which multiplies predominantly within human macrophages. This organism has previously been shown to induce apoptosis in human macrophages. With a view to identifying M. avium components that induce cell death in infected host cells, sonicated extracts of M. avium as well as individual components isolated from the M. avium sonicate were tested in ...

Mycobacterium avium subsp. hominissuis is an opportunistic pathogen present in soil and dust. We report M. avium subsp. hominissuis infection found in a domestic rabbit in Hannover, Germany, in May 2017.
