The aim of this study was to determine antimicrobial resistance provide molecular characterization MRSA non-Staphylococcus staphylococci (MRnSA) wildlife that carried the gene mecC. Five S. one coagulase-negative isolate displaying phenotypic oxacillin resistance, but not recognized with conventional PCR for mecA, were further...
Abstract Structures of the hyoid apparatus, pharynx and their topographical positions in lion, tiger, jaguar, cheetah domestic cat were described order to determine morphological differences between species or subfamilies Felidae. In tiger jaguar (species subfamily Pantherinae) Epihyoideum is an elastic ligament lying lateral pharyngeal muscles Musculus ( M .) thyroglossus rather than a bony element like cat. The M. was only present Pantherinae studied. lion Thyrohyoideum thyroid cartilage...
The red fox (Vulpes vulpes) is a widespread species, harbouring many pathogens relevant for humans and pets. Indeed, Anaplasma spp., Ehrlichia canis Rickettsia spp. among the bacteria Hepatozoon as well Babesia sp. parasites have been focus of several studies. In cohort 36 foxes shot on one day in north-eastern part Austria, microti-like were found 50%, while H. was detected 58.3% samples. spleen more useful detection canis, whereas B. frequently blood. Bacteria could not be confirmed any...
The order Accipitriformes comprises the largest group of birds prey with 260 species in four families. So far, 21 haemosporidian parasite have been described from or reported to occur accipitriform birds. Only five these characterized molecular genetically. first part this study involved genetic screening raptors Austria and Bosnia-Herzegovina chromogenic situ hybridization approach targeting parasites host group. aim second was summarize CytB sequence data visualize geographic distribution...
The garden dormouse (Eliomys quercinus) is a fat-storing mammal that undergoes annual periods of hibernation to mitigate the effects food scarcity, low ambient temperatures, and reduced photoperiod characterize winter. Like other hibernating species, this animal suppresses its metabolic rate by downregulating nonessential genes processes in order prolong available energy stores limit waste accumulation throughout season. MicroRNAs (miRNAs) are short, single-stranded, noncoding RNAs bind mRNA...
Low-carbohydrate, high-fat ketogenic diets (KDs) are used to treat drug-resistant epilepsy, and other potential benefits for treating neurological disorders, metabolic syndrome, cancer being explored. In addition these medical applications, KDs have also become popular rapid weight-loss enhancing athletic performance. However, the effects of exposing developing offspring during pregnancy (gestational KD) poorly understood, especially their long-term health consequences. this study, we...
The garden dormouse is listed as "near threatened" on the IUCN Red List of threatened species. Research this species concentrates primarily their hibernating strategies and physiology. However, little known about infectious entities in species, even less neoplastic diseases. This case series presents first report different neoplasms a population dormice (Eliomys quercinus) under human care. includes six animals (four males, two females, four to seven years old). Four were euthanized, found...
ABSTRACT Anthropogenic activities threaten many wildlife populations by increasing mortality rates, making it crucial to identify the locations and causes of inform conservation actions. Technological advancements, such as GPS satellite tracking, enable precise recording movements. High‐resolution data from devices can facilitate rapid carcass recovery provide insights into tagged individuals. Obtaining required information determine these is complex, standardized approaches overcome...
Avian haemosporidian parasites can cause severe disease in their hosts due to excessive exo-erythrocytic merogony and anaemia caused by blood stages. Notably, the development of megalomeronts species Haemoproteus Leucocytozoon has been associated with mortalities birds. Diagnosis lethal infections is currently accomplished detection parasites' tissue stages histological sections combined PCR sequencing. However, sequences frequently are not reliably obtained generic discrimination based on...
Dietary lipids strongly influence patterns of hibernation in herbivores. Increased dietary uptake n-6 polyunsaturated fatty acids (PUFA), particularly linoleic acid (LA, C18:2 n-6), enables animals to reach lower body temperatures (Tb), lengthens torpor bout duration, and results energy expenditure during hibernation. Conversely, n-3 PUFA impacts negatively on performance. surrounding phospholipids (PL) presumably modulate the temperature-dependent activity sarcoplasmic reticulum (SR) Ca2+...
Manuls or Pallas' cats (Felis manul, syn. Otocolobus manul) are endangered wild from Central Asia kept and bred in many zoos. Despite good breeding success young frequently die acute toxoplasmosis. From 1998 to 2002, a pair the Schönbrunn Zoo Vienna, Austria, gave birth 24 kittens; 58 % of kittens died between 2nd 14th week life, mostly due The epidemiology toxoplasmosis was examined control strategy protect fatal developed. One 12-week-old kitten litter 6 born 2001 generalized This had shed...
In mammals, cone photoreceptor subtypes are thought to establish topographies that reflect the species-relevant properties of visual environment. Middle- long-wavelength-sensitive (M) cones dominant population and in most species they form an area centralis at axis. Short-wavelength-sensitive (S) do not always match this pattern. We here correlate interrelationship S M representatives several mammalian orders with different ecology, including man, cheetah, cat, Eurasian lynx, African lion,...
Abstract Diseases of the gastrointestinal tract due to changes in bacterial flora have been described with increasing incidence European brown hare. Despite extensive demographic and phylogeographic research, little is known about composition its gut microbiota how it might vary based on potential environmental or host factors. We analysed intestinal faecal 3 hare populations by Illumina MiSeq 16S rRNA gene amplicon sequencing. The phyla OTU abundance differed significantly between samples...

The European brown hare (Lepus europaeus) is an herbivorous mammal of high ecological impact, which widespread throughout Europe. Despite its ability to adapt varying habitat conditions, this species has experienced a decline in numbers since the 1960s. Pathological examinations dead individuals from different geographical regions have shown that most animals suffer intestinal inflammation with changes mucosa resulting diarrhoea and death. Nevertheless, even after years extensive research...
In the course of Fukushima nuclear accident large amounts radionuclides relevant to Comprehensive Nuclear-Test-Ban-Treaty (CTBT) were released and detected globally. We could show that intake environmental (131)I into thyroids animals can be used for verification CTBT. Due continuous accumulation (131)I, its apparent half-life in thyroid biomonitor exceeds physical one, thus making detectable three weeks longer than using conventional CTBT-grade high volume air samplers. The maximum activity...

Additionally, routine bacteriology intestine...
In most mammals short-wavelength-sensitive (S) cones are arranged in irregular patterns with widely variable intercell distances. Consequently, mosaics of connected interneurons either may show some type correlation to photoreceptor placement or establish an independent lattice compensatory dendritic organization. Since axonless horizontal cells (A-HC's) supposed direct all dendrites overlying cones, we studied their spatial interaction chromatic cone subclasses. the cheetah, bobcat, and...
Torpor or heterothermy is an energy‐saving mechanism used by endotherms to overcome harsh environmental conditions. During winter, the garden dormouse ( Eliomys quercinus ) hibernates with multiday torpor bouts and body temperatures of a few degrees Celsius, interrupted brief euthermic phases. This study investigates gene expression within hypothalamus, key brain area controlling energy balance, adding information on differential potentially relevant orchestrate torpor. A de novo assembled...
