Reighardia sternae is a pentastomid parasitising the respiratory system of larids and skuas, pathological significance which still poorly understood. In this study, pentastomes found in interclavicular air sac deceased necropsied yellow-legged gull (Larus michahellis) were identified by parasitological molecular methods associated gross histopathological lesions evaluated. After morphological evaluation characterisation, species R. was identified. This first report infecting L. michahellis...
The avian iris is mainly composed of striated muscle fibers, and the topical parasympatholytic drugs used in mammals to induce pupil dilation are ineffective birds. achievement mydriasis conscious birds only possible by using neuromuscular blocking agents such as curariform drugs. To determine efficacy agent rocuronium bromide a mydriatic European kestrels (Falco tinnunculus) assess adverse effects due its use, 10 received single instillation with pipette 0.12 mg each eye (total dose, 0.24...

Bacteria of the genus Enterococcus are opportunistic pathogens, part normal intestinal microflora animals, able to acquire and transfer antimicrobial resistance genes. The aim this study was evaluate possible role wild avifauna as a source antimicrobial-resistant enterococci. To assess purpose, 103 spp. strains were isolated from feces birds different species; they tested for against 21 molecules, vancomycin resistance, high-level aminoglycosides (HLAR). Furthermore, genes responsible...
Abstract Objective To evaluate the mydriatic efficacy of a neuromuscular blocking agent (rocuronium bromide) applied topically to only one eye nocturnal birds prey and assess for any general and/or local adverse effects due its use. Animal studied Twelve healthy adult tawny owls ( Strix aluco ) were randomly divided in two groups. Procedures Six (Group 1) received single dose 0.35 mg rocuronium bromide. The second group subjects 2) doses bromide (total 0.70 mg/eye). In both groups,...
Abstract Objective To evaluate the achievement of a bilateral mydriasis in raptors induced by concurrent topical application rocuronium bromide and to assess any side effects that might result from its use. Animals studied Ten healthy adult common buzzards ( Buteo buteo ) 10 little owls Athene noctua ). Procedures Common (Group 1) received single dose 0.40 mg each eye (total 0.80 mg/bird), whereas 2) 0.20 mg/bird). The drug was topically instilled all birds both groups. pupil diameter...
Toxoplasma gondii is an obligate apicomplexan zoonotic parasite that infects humans and other animals responsible for toxoplasmosis. This causes one of the most common parasitic infections in worldwide. Toxoplasmosis meets requirements a One Health Disease due to its ability affect health human beings as well domestic free ranging animals. Integrating human, animal, wildlife data could better assess risk devise methods control. A first step such approach would be knowledge prevalence...
The combined actions of climatic variations and landscape barriers shape the history natural populations. When organisms follow their shifting niches, obstacles in can lead to splitting populations, on which evolution will then act independently. two such populations are reunited, secondary contact occurs a broad range admixture patterns, from narrow hybrid zones complete dissolution lineages. A previous study suggested that barn owls colonized Western Palearctic after last glaciation...
Objective: To investigate the potential role of wild birds as fecal spreaders enteropathogenic, enterohemorrhagic and Shiga-toxins producing Escherichia coli (E. coli), enteropathogenic E. coli, Shiga toxin-producing strains.Methods: Fecal samples collected from 121 different orders species were submitted to molecular analyses. In particular, eaeA encoding intimin, hlyA for hemolysin, stx1 stx2 genes 1 2, respectively, investigated.Results: Overall, 21(17.35%) resulted positive at least one...
In literature it is established that the iris musculature consists of striate muscle fibers in birds while mammals smooth muscles.Some authors report presence tissue also some species birds.In present study we on tissues (type tissue, direction and mean diameter or cells) five Accipitriformes (diurnal raptors) four Strigiformes (nocturnal because they show different way life depending their predatory behavior.This morphological was carried out from raptors died euthanized at Wild Life Rescue...
The study of insular populations was key in the development evolutionary theory. successful colonisation an island depends on geographic context, and specific characteristics organism island, but also stochastic processes. As a result, apparently identical islands may harbour with contrasting histories. Here, we use whole genome sequences 65 barn owls to investigate patterns inbreeding genetic diversity eastern Mediterranean Sea. We focus Crete Cyprus, similar size, climate distance...
Birds are known to be carriers of ticks infected by tick-borne pathogens, including bacteria. However, not many studies have been carried out on avian tissues detect these agents. The aim the present survey was investigate, using PCR, presence Anaplasma phagocytophilum, Bartonella spp., Borrelia burgdorferi sensu lato, Chlamydia psittaci, Coxiella burnetii, Ehrlichia canis, Francisella tularensis, and Rickettsia spp. in spleens collected from 300 wild birds different orders species Central...
To assess the effect of rocuronium bromide-induced mydriasis on intraocular pressure (IOP) kestrels (Falco tinnunculus) and little owls (Athene noctuae).13 adult 13 owls.All birds were ophthalmologically normal. During first 2 treatment periods, a 1% bromide solution was topically instilled in both eyes all at dose 0.12 mg (12 μL) for 0.20 (20 owls. No ophthalmic treatments administered during second (control) period, which conducted 1 week after first. rebound tonometry used to measure IOP...
The role of avian species in the Neospora caninum life cycle has not been completely elucidated, and epidemiological data from Europe are scant. aim present report was to evaluate presence N. DNA tissues 302 birds belonging different species, along with IFAT titers. Forty-two out (13.9%) showed low serological titers (1/50 1/100) against caninum. These data, positive for 31 animals (10.3%), were corroborated by PCR. Twenty-two hearts eighteen brains scored positive, while nine subjects...
A 3-yr-old male Gouldian finch (Erythrura gouldiae) died after 2 wk of lethargy, emaciation, feather loss, and abdominal distension. The bird was housed in an aviary for breeding, but it had shown loss fertility the previous breeding season. Necropsy revealed a gross, firm, yellow mass involving left testis. Histologically, mixed form, intratubular diffuse, Sertoli cell tumor. Some neoplastic cells intranuclear inclusion bodies that immunoelectron microscopy proved to be polyomavirus...
Avipoxviruses (APVs) are important pathogens of both domestic and wild birds. The associated disease is characterized by skin proliferative lesions in the cutaneous form or first digestive respiratory tracts diphtheritic form. Previous studies investigated these infections symptomatic birds worldwide, including Italy, but data about circulation APVs healthy avian wildlife not available. present study tested spleen samples from 300 without typical to detect Avipoxvirus DNA. Overall, 43.33%...
The Leucocytozoon genus comprises numerous widely distributed parasites which have been less investigated than other avian hemoprotozoa. Their occurrence is common, with very variable prevalence values and pathogenicity degrees. species are characterized by a great taxonomic diversity, infections usually restricted to birds of the same family. In present paper, mixed hemosporidia infection californicus Haemoproteus sp. in an adult male merlin (Falco columbarius) died during hospitalisation...

Seagulls are synanthropic wild birds that can contaminate, through their droppings, beaches, urban and peri-urban environments. This concern is more serious when seagulls eliminate antimicrobial-resistant pathogenic bacteria. study analyzed the fecal samples from 137 yellow-legged (Larus michahellis) Central Italy. A total of 218 Escherichia coli strains were isolated for phenotypic genotypic antimicrobial resistance to identify virulence genes characterizing different pathotypes. The disk...
Two Eurasian Blackbirds (Turdus merula) from central Italy were found with severe cyclocoelid trematodosis associated airsacculitis. The birds submitted respiratory distress; one died shortly after hospitalization, while the second bird was euthanized. At necropsy, a massive presence of flukes observed in coelomic cavity and air sacs both birds. diffusely opaque, thickened, covered by scant fibrinous exudate mixed numerous parasites. Histologically, showed diffuse oedema exudate. Diffuse...
