An Outbreak of Aeromonas salmonicida in Juvenile Siberian Sturgeons (Acipenser baerii).

Aeromonas salmonicida is one of the major threats to world aquaculture, causing fish furunculosis and high mortality rates in cultured fish, particularly salmonids. Although Aeromonas spp. is a thoroughly studied pathogen, little is known regarding aeromoniasis in sturgeons. After a mortality outbreak, four juvenile sturgeons (Acipenser baerii) were submitted for autopsy and tissue samples were collected for histopathological and microbiological studies. The external examination revealed size heterogenicity, skin hyperpigmentation and reduced body condition of sturgeons. Within the abdominal c…

Detection of variants of the pRAS3, pAB5S9, and pSN254 plasmids in Aeromonas salmonicida subsp. salmonicida: multidrug resistance, interspecies exchanges, and plasmid reshaping.

The ubiquitous water-borne Gram-negative bacterium Aeromonas salmonicida subsp. salmonicida is the causative agent of furunculosis, a worldwide disease in fish farms. Plasmids carrying antibiotic resistance genes have already been described for this bacterium. The aim of the present study was to identify and characterize additional multidrug resistance plasmids in A. salmonicida subsp. salmonicida. We sequenced the plasmids present in two multiple antibiotic-resistant isolates using high-throughput technologies. We also investigated 19 other isolates with various multidrug resistance profiles …

Survey of dermatological conditions in a population of domestic dogs in Mashhad, northeast of Iran (2007-2011).

university small animal clinic, 1299 Iranian domestic dogs presented from September 2007 through March 2011 to the Ferdowsi University of Ma … estation and allergy, tick infestation, atopic dermatitis, scabies, unspecified dermatoses, otitis, furunculosis and food allergy. There were no apparent age or sex predilections for dermatological disease as a whole. Spitz (odds ratio = 3.38; p = 0.001), Terriers (odds ratio = 2.52; p < 0.001) and German Shepherds (odds ratio = 1.90; p = 0.001) appeared to be …

Control of a cluster of community-associated, methicillin-resistant Staphylococcus aureus in neonatology.

To control an outbreak of community-associated MRSA (CA-MRSA) in a neonatology unit, an investigation was conducted that involved screening … ns terminated the outbreak. Four months after the outbreak, the mother of another neonate developed furunculosis with the epidemic CA-MRSA strain. One infant had persistent CA-MRSA carriage resulting in skin infection in a sibling four years after the outbreak. In conclusion, an epidemic CA-MRSA strain was introduced by the mother of the index case. This sprea …

Recent developments in fish vaccinology.

During the last 10 to 20 years vaccination has become established as an important method for prevention of infectious diseases in farmed fish, mainly salmonid species. So far, most commercial vaccines have been inactivated vaccines administered by injection or immersion. Bacterial infections caused by Gram-negative bacteria such as Vibrio sp., Aeromonas sp., and Yersinia sp. have been effectively controlled by vaccination. With furunculosis, the success is attributed to the use of injectable vaccines containing adjuvants. Vaccines against virus infections, including infectious pancreatic necro…

Prolonged Brackish Water Exposure: A Case Report.

Exposure to and consumption of brackish water are associated with an elevated risk of infection, hypernatremia, and hypothermia. Minimal data exist to support the diagnosis and treatment of patients with long-term brackish water exposure. We present a case of a patient who spent 5 to 10 d semisubmerged in the Elizabeth River in coastal Virginia. A 55-y-old male presented via ambulance after 5 to 10 d of being "stuck in the mud." He was hypernatremic, with a sodium of 176 mEq·L-1, hypothermic to 34.5°C (94.1°F), and hypotensive at 88/50 mm Hg, with a sodium concentration of 176 mEq·L-1 and an o

High immunogenicity of virus-like particles (VLPs) decorated with Aeromonas salmonicida VapA antigen in rainbow trout.

The Gram-negative bacterium A. salmonicida is the causal agent of furunculosis and used to be one of the most loss-causing bacterial infections in the salmonid aquaculture industry with a mortality rate of about 90% until the 1990s, when an inactivated vaccine with mineral oil as adjuvant was successfully implemented to control the disease. However, the use of this vaccine is associated with inflammatory side effects in the peritoneal cavity as well as autoimmune reactions in Atlantic salmon, and incomplete protection has been reported in rainbow trout. We here aimed at developing and testing …

Isolation and identification of vapA-absent Aeromonas salmonicida in diseased snakehead Channa argus in China.

Aeromonas salmonicida is the typical pathogen causing furunculosis, reported widely in salmonids. Because of multiple serotypes, the control of A. salmonicida-caused disease has increasingly received much attention. Recently, A. salmonicida infection was reported in non-salmonid fish species. Here, a pathogenic A. salmonicida, named as As-s, was isolated from cultured snakehead (Channa argus) in a local fish farm in Shandong, China. As-s displayed clear hemolysis, amylase, and positive catalase activities, and grew at a wide range of temperatures (10-37 °C) and pH values (5.5-8.5). As-s was hi…

Antibacterial treatment of lumpfish (Cyclopterus lumpus) experimentally challenged with Vibrio anguillarum, atypical Aeromonas salmonicida and Pasteurella atlantica.

Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there … ith pasteurellosis. None of the antibacterial agents were efficient to treat lumpfish with atypical furunculosis. FFC 20 mg kg-1  day-1 showed promising results in the beginning of the experiment, but the mortality increased rapidly 14 days post-medication. Efficient treatment is important for the welfare of lumpfish and for reducing the risk of development of …

Cutaneous myiasis in an elderly woman in Somaliland.

BACKGROUND: Cutaneous myiasis is a self-limited skin infestation by developing fly larvae, with three clinical subtypes: furuncular, migrato … ermatosis associated with travel to endemic areas. Furuncular myiasis can easily be misdiagnosed as furunculosis or cellulitis. Dermatologists must be familiar with the clinical features and management of this dermatosis.

Рекомбинантный аденовирус, нацеленный на типичную Aeromonas лососевицику, вызывает адаптивную иммунную реакцию на антитела после иммунизации радужной форели.

Aeromonas лососьицида, самый старый известный патоген рыбы, который в настоящее время является эндемичным во всем мире как в пресной, так и в морской воде, причиняет серьезные экономические потери земледельчеству. Несмотря на то, что за последние несколько десятилетий было проведено много исследований по вопросу о предотвращении фураскоза, он по-прежнему распространен во многих рыболовецких промыслах. В этом исследовании была успешно разработана и опробована рекомбинантная аденовирусная вакцина, содержащая высокоиммуногенный ген Вапа (pad-easy-cmv-Vapa). Затем после иммунизации радужной форели

Aeromonas salmonicida, the oldest known fish pathogen and currently endemic throughout most of the world in both fresh and marine waters, causes severe economic losses to the salmon farming industry. Although there have been many studies on the prevention of furunculosis over the past few decades, it is still prevalent in many fisheries. In this study, a rec…

[Cutaneous myiasis caused by a double infestation with larvae of Dermatobia hominis and Cochliomyia hominivorax].

In a 51-year-old man who had visited Surinam, cutaneous myiasis was diagnosed, caused by simultaneous infestation with the larvae of two different species of flies: Dermatobia hominis and Cochliomyia hominivorax. On his right lower arm the man had two solitary, furuncle-like lesions with a central breathing hole. Two days after these holes had been occluded with vaseline, two white larvae of D. hominis emerged. On both ankles the man had large, undermined ulcers containing hundreds of creeping larvae about 2 cm in length with a salmon-like colour: C. hominivorax. The larvae were removed from t
