ABSTRACT

BACKGROUND: The aim of the study was to investigate the use of single-pedicle advancement flaps in the fixed skin regions of the head, neck and paravertebral region in guinea pigs. METHODS: Ultrasonography was performed on the guinea pigs to visualise the vascular anatomy of the looser regions of the thorax and abdomen and the more fixed paravertebral region and neck. Flap surgeries were then planned and undertaken on seven guinea pigs, with six having tumours on the lip, under the eye, the forehead, the neck or the paravertebral pelvic region, and one having a large paravertebral pelvic scar of unknown origin altering the animal's movement. The previously recommended 2:1 flap length:base width ratio was not enough in most cases, so larger flaps (3.5:1) were required. RESULTS: All seven single-pedicle advancement flaps survived and healed with outstanding results. CONCLUSION: The authors recommend to use reconstructive surgery in guinea pigs when there is a need to close large or difficult wounds, even on areas of fixed skin. Adequate arterial supply and sufficient venous outflow can be provided with larger flap length:base width ratios than previously suggested and can lead to full recovery.

ABSTRACT

The West Nile virus is endemic in multiple European countries and responsible for several epidemics throughout the European region. Its evolution into local or even widespread epidemics is driven by multiple factors from genetic diversification of the virus to environmental conditions. The year of 2018 was characterized by an extraordinary increase in human and animal cases in the Central-Eastern European region, including Hungary. In a collaborative effort, we summarized and analyzed the genetic and serologic data of WNV infections from multiple Hungarian public health institutions, universities, and private organizations. We compared human and veterinary serologic data, along with NS5 and NS3 gene sequence data through 2018. Wild birds were excellent indicator species for WNV circulation in each year. Our efforts resulted in documenting the presence of multiple phylogenetic subclades with Balkans and Western-European progenitor sequences of WNV circulating among human and animal populations in Hungary prior to and during the 2018 epidemic. Supported by our sequence and phylogenetic data, the epidemic of 2018 was not caused by recently introduced WNV strains. Unfortunately, Hungary has no country-wide integrated surveillance system which would enable the analysis of related conditions and provide a comprehensive epidemiological picture. The One Health approach, involving multiple institutions and experts, should be implemented in order to fully understand ecological background factors driving the evolution of future epidemics.

ABSTRACT

A male kowari (Dasyuroides byrnei) originating from a zoo facility was delivered for post mortem evaluation in Hungary. Acute lobar pneumonia with histopathologic changes resembling an adenovirus (AdV) infection was detected by light microscopic examination. The presence of an AdV was confirmed by obtaining partial sequence data from the adenoviral DNA-dependent DNA-polymerase. Although the exact taxonomic position of this novel marsupial origin virus could not be determined, pairwise identity analyses and phylogenetic calculations revealed that it is distantly related to other members in the family Adenoviridae.

ABSTRACT

Ninety-one red squirrels (Sciurus vulgaris) found dead in the UK between January 1994 and August 1998 were necropsied at the Institute of Zoology (London, UK); their oral cavities were examined visually, and in eight cases, radiographically. Four red squirrels, which had evidence of oral disease when necropsied as part of a mortality survey, also were examined. A low prevalence (prevalence = 0.033, SE = 0.02, n = 91) of oral disease was found in free-living red squirrels. In only two cases was oral disease the probable cause of death. Attrition of the check teeth (three cases) and overgrowth of the incisors (four cases) were the most common lesions found. Partial anodontia was recorded in one squirrel.
