From October 2021 to January 2022, different incursions of clade 2.3.4.4b H5N1 HPAIV (Highly Pathogenic Avian Influenza Virus) occurred in several Italian regions with its main diffusion Densely Poultry Populated Areas (DPPAs) north-eastern Italy. Monitoring and control activities applied the affected area clearly evidenced that turkeys broilers were most species, although flocks at times resulted infected absence increased mortality and/or clinical signs. Thus, an approach based on sampling...
Mycoplasma synoviae (MS) is a highly prevalent bacterial species in poultry causing disease and severe economic losses. Antibiotic treatment one of the control strategies that can be applied to contain clinical outbreaks MS-free flocks, especially because this bacterium transmitted ovo. It becomes, then, very important for veterinarians know antibiotic susceptibility circulating strains order choose most appropriate first-line molecule as proactive role fighting resistance. We evaluated...
Mycoplasmas are known as the minimalist microorganisms in microbes' world. Their nature makes them highly sensitive to environmental conditions and limits their ability survive for extended periods outside animal host. Nevertheless, there documented instances of mycoplasma transmission over significant distances this phenomenon may be linked relatively unexplored abilities mycoplasmas, such capacity synthesize biofilm—the predominant mode bacterial growth nature. The authors decided...
This study aims to investigate the bacteria involved in equine omphalitis and their susceptibility antimicrobial drugs, consequently provide guidelines concerning most suitable treatment protocol accordance with clinical, ultrasound laboratory findings. Forty foals aged between one 30 days were evaluated course of this investigation. An examination all umbilical remnants was carried out carefully foals; swabs collected for bacteriological examination, blood samples culture from 19 fever...
Mycoplasma gallisepticum (Mg) is a highly contagious avian pathogen responsible for significant economic losses the poultry industry. In some circumstances, antimicrobial treatment useful to contain clinical signs of Mg infection in birds. However, resistance emergence now common among animal pathogens, becoming worldwide health concern. The collection minimum inhibitory concentration (MIC) data fundamental an appropriate use and fighting emergence. MIC can only be generated specialized...
The Mycoplasma synoviae live attenuated vaccine strain MS-H (Vaxsafe MS; Bioproperties Pty., Ltd., Australia) is commonly used around the world to prevent chronic infections caused by M. in birds and minimize economic losses poultry industry. a temperature-sensitive that generated via chemical mutagenesis of virulent isolate, 86079/7NS. 32 single nucleotide polymorphisms have been found genome compared 86079/7NS, including 25 predicted coding sequences (CDSs). There limited information on...
Canine herpesvirus-1 (CaHV-1) is a globally distributed pathogen causing reproductive, respiratory, ocular and neurological disorders in adult dogs neonatal death puppies. This considered poorly immunogenic, neutralizing antibodies are found for only short time following exposure. Further, seroprevalence can be affected by several epidemiological factors. A virological survey was conducted high-density population breeding kennel Central Italy. There were factors predisposing animals to...
A retrospective study was conducted to investigate the presence of ferlavirus, ball python nidovirus and bacteria in 32 tracheobronchial lavages from pythons raised captivity affected by respiratory disease. touchdown reverse transcription polymerase reaction (RT-PCR) performed detect RNA targeting a 260-bp portion ORF1a gene, while nested RT-PCR applied identify 518-bp ferlavirus partial L gene. positive products were submitted for Sanger's sequencing phylogeny reconstruction....
With more than 120 species, the genus Mycoplasma is one of largest taxa in class Mollicutes, a group micro-organisms that are characterized by apparent simplicity and to which important animal pathogens belong. Mycoplasmabovis most frequently identified pathogenic cattle; however, prevalence other species living calves' airways poorly understood. The aim this work was characterize respiratory tract mycoplasma populations calves on dairy farms Italy using real-time PCR assay DNA microarray...
The first two European outbreaks of herpetic pneumonia caused by Psittacid alphaherpesvirus-5 were diagnosed based on gross pathology findings, histological examination, transmission electron microscopy visualization and genome sequencing. outbreaks, characterized high morbidity mortality rates, involved parrot species, namely the Indian ringneck (Psittacula krameri) Alexandrine parakeet eupatria). Clinical signs observed ruffled feathers, dyspnea, tail bobbing, open wings while breathing,...
Mycoplasma dispar is an overlooked pathogen often involved in bovine respiratory disease (BRD), which affects cattle around the world. BRD results lost production and high treatment prevention costs. Additionally, chronic therapies with multiple antimicrobials may lead to antimicrobial resistance. Data on susceptibility M. limited so minimum inhibitory concentrations (MIC) of a range routinely used were evaluated using broth microdilution technique for 41 isolates collected Italy between...
Mycoplasma iowae, a pathogen affecting the turkey industry, is commonly associated with decreased hatchability and leg abnormalities in young progeny. This was spotlight more past than today since its prevalence has been decreasing over time. Reports of M. iowae turkeys showing reduced growth performances, problems skeletal are scarce although there no report whether this completely eradicated commercial turkeys. Additionally, comprehensive epidemiological data available on any country....
In 2017, respiratory disease and low mortality were reported in domestic flying pigeons (Columba livia var. domestica) trained as hunting live bait a breeding farm Umbria, Italy. Clinically, open beak breathing, dropped wings, pharyngeal laryngeal hyperaemia observed. Three birds submitted for necropsy. Gross pathological evaluation revealed all cases diffuses of the tracheal mucosa association with mild emaciation multiorgan congestion. Microscopically, diffuse epithelial hyperplasia...
Mycoplasma iowae is a worldwide spread and economically important avian pathogen that mostly infects turkeys. Currently, multi-locus sequence typing (MLST) serves as the gold standard method for strain identification in M. iowae. However, additional robust genotyping methods are required to effectively monitor infections conduct epidemiological investigations. The first aim of this study was develop assays with high resolution, specifically target iowae, namely multiple-locus variable number...
