Two water buffaloes (male and female) serologically positive to glycoprotein E (ELISA IDEXX gE) were pharmacologically treated to reactivate the putative herpesvirus from latency. Nasal swabs, blood samples, preputial and vaginal swabs were tested for herpesvirus by classical and Real-Time PCR. Samples positive to both PCR analyses were used for virus isolation. Nucleotide sequence analysis of the genes coding for gB and gD indicated that the isolated viral strains were BuHV-1. [ABSTRACT FROM AUTHOR]

Gunshot wound morphology and gunshot residues (GSRs) evaluation have been poorly investigated in veterinary forensic pathology. The aims of the present study were to assess the gunshot wound morphology in animals and evaluate the detectability of lead deriving from GSRs using colorimetric techniques. To these aims, cadavers were divided into four different groups. Group A comprised eight animals who died from firearm-related injuries, while groups B and C included dog limbs shot using different shooting ranges; group D comprised dog limbs stabbed with a screwdriver. Morphological analysis was performed on all entry gunshot wounds. Lead residues were investigated using a Bullet Hole Testing Kit ( BTK ) and Rhodizonate Sodium histochemical staining ( NaR-s ). Gunshot wounds in group A showed an abrasion ring associated with hemorrhages and tissue necrosis. Groups B and C showed injuries related to the shooting range. NaR-s showed positive results in both animals that died from gunshot wounds and experimentally shot limbs. However, the number of positive cases and the pattern of lead distribution varied with the shooting range. Positive results by BTK were limited to close-contact shots in group B limbs. Our results suggest that both pathological examination and NaR tests represent valid tools for investigating gunshot wounds in veterinary pathology.

Estimation of age represents a central focus in the veterinary forensic pathology field. Currently, the visual examination of the dentition and the skeletal age are the main methods to estimate the age of puppies. Nevertheless, these methods are affected by a broad range of variables. In contrast, the kidney is characterized by a specific postnatal development. In human glomerulogenesis, fetal mesangial cells change their immunohistochemical phenotypes with maturation. Therefore, we hypothesized that histological and immunohistochemical examinations of the kidney can be used together as an indirect parameter for age determination in puppies' cadavers. Forty-five puppies' cadavers were divided into five groups defined by age (Group A= 0-15 days, Group B = 16-45 days, Group C = 46-85 days, Group D = 86-105 days, Group E= 105-365 days). For each case, kidney samples were collected and processed for histopathological (for morphometrical study of the glomerulus) and immunohistochemical (for the immunolocalization of the α-SMA protein) studies. Morphometrical study allowed us to observe statistical differences in the mean glomerulus numbers per field among assessed groups. Similarly, immunohistochemical examination showed differences in SMA expression among groups. Our findings suggest a potential use of kidney morphometrical and immunohistochemical examinations together as an indirect parameter to assess the age of illegally imported puppies.

From 2019 to 2021, a retrospective molecular study was conducted in the Campania region (southern Italy) to determine the prevalence of viral diseases in domestic cats. A total of 328 dead animals were analyzed by Real-Time PCR for the presence of feline panleukopenia virus (FPV), feline leukemia virus (FeLV), feline enteric coronavirus (FCoV), rotavirus (RVA), feline herpesvirus type 1 (FHV-1), and feline calicivirus (FCV). The possible presence of SARS-CoV-2 was also investigated by Real-Time PCR. The cats included in this study were specifically sourced and referred by local veterinarians and local authorities to the Zooprofilactic Experimental Institute of Southern Italy (IZSM) for pathological evaluation. The samples consisted of owners, catteries, and stray cats. Results revealed: 73.5% positive cats for FPV (189/257), 23.6% for FeLV (21/89), 21.5% for FCoV (56/266), 11.4% for RVA (16/140), 9.05% for FeHV-1 (21/232), and 7.04 for FCV (15/213). In contrast, SARS-CoV-2 was never detected. FPV was more prevalent in winter ( p = 0.0027). FCoV FHV-1, FCV, and RVA predominated in autumn, whereas FeLV predominated in summer. As expected, viral infections were found more frequently in outdoor and shelter cats than in indoor ones, although no statistical association was found between animal lifestyle and viral presence. The study showed a high prevalence of FPV, FeLV, and FCoV and a moderate prevalence of RVA, FHV-1, and FCV. Moreover, the prevalence of these pathogens varied among the cat populations investigated.

This study aims to investigate the presence of canine distemper virus (CDV) infection in 949 autochthonous or illegally imported dogs from Southern Italy, over a period of eight years (2014-2021). CDV RNA was detected in 6.8% (65/949) of the animals tested, with no detection of CDV in dogs sampled in 2020-2021. The frequency of CDV detection was higher in imported dogs (19/103, 18.3%) with respect to stray (27/365, 7.4%) and household dogs (19/481, 3.9%). On sequence and phylogenetic analyses of selected strains, the analyzed viruses belonged to the Arctic clade, which has already been reported in Italy and in Europe. The results of our study may suggest a reduction of CDV circulation in Southern Italy, while at the same time highlighting the need for strict controls on dog importation, in order to prevent the introduction of viruses from endemic countries.

A six-year study on water buffaloes from the Campania Region (Southern Italy) was conducted to evaluate the presence of bovine/bubaline herpesviruses in cases of abortion. A total of 244 buffalo foetuses were analysed by real-time PCR to detect the presence of: bovine alphaherpesvirus 1(BoHV-1), bubaline alphaherpesvirus 1 (BuHV-1), bovine alphaherpesvirus 2 (BuHV-2), and bovine gammaherpesvirus 4 (BoHV-4). The foetuses of 14 water buffaloes that showed abortions were positive for BuHV-1 (4 animals) and/or BoHV-4 (11 animals), with one of these cases showing co-infection with BuHV-1 and BoHV-4. This study reports the first identification of BoHV-4 in water buffaloes. Cases of abortion were analysed using both molecular and cultural assays for the presence of other pathogens. In nearly all the abortion cases positive for BoHV-4, the virus was identified as a co-infecting agent together with other microorganisms, whereas in two abortion cases, it was the only pathogen found., (© 2022.

A case of Mycobacterium tuberculosis infection is described in a dead adult male dog in Southern Italy. The carcass was found by the Health Authority in a gypsy encampment. It was admitted to our forensic veterinary medicine unit, with a suspicion of cruelty to the animal. Necropsy showed beating and traumatism signs, and mistreating was confirmed. Gross lesions included multiple nodular hepatic lesions, hemorrhagic enteritis with enlarged mesenteric lymph nodes, body cavity effusions, and an adrenal neoplasm. Bacteriological and molecular analyses were carried out on the liver lesions that enabled to identify M. tuberculosis SIT42 (LAM9). Drug-resistance patterns were evaluated by screening mutations on the rpoB and katG genes that showed susceptibility to both rifampin and isoniazid, respectively. Very few studies report canine tuberculosis, and little is known about the disease in Italy. To the authors' knowledge, this is the first report of Mycobacterium tuberculosis SIT42 infection in a dog in Italy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Vangone, Cardillo, Riccardi, Borriello, Cerrone, Coppa, Scialla, Sannino, Miletti, Galiero and Fusco.)

Canine coronavirus (CCoV) strains with the ability to spread to internal organs, also known as pantropic CCoVs (pCCoVs), have been detected in domestic dogs and wild carnivores. Our study focused on the detection and molecular characterization of pCCoV strains circulating in Italy during the period 2014-2017 in autochthonous dogs, in dogs imported from eastern Europe or illegally imported from an unknown country. Samples from the gut and internal organs of 352 dogs were screened for CCoV; putative pCCoV strains, belonging to subtype CCoV-IIa, were identified in the internal organs of 35 of the examined dogs. Fifteen pCCoV strains were subjected to sequence and phylogenetic analyses, showing that three strains (98960-1/2016, 98960-3/2016, 98960-4/2016) did not cluster either with Italian or European CCoVs, being more closely related to alphacoronaviruses circulating in Asia with which they displayed a 94%-96% nucleotide identity in partial spike protein gene sequences. The pCCoV-positive samples were also tested for other canine viruses, showing co-infections mainly with canine parvovirus., (© 2020 The Authors.

The zoonotic filarioid nematode Dirofilaria immitis is transmitted by bloodsucking mosquitoes and causes heartworm disease in dogs and wild canines. In the last decade, D. immitis has spread in southern Europe including Italy. Few autochthonous foci of infection have been reported in previously non-endemic areas of southern Italy based only on the identification of microfilariae, antigen and serological tests, and polymerase chain reaction assay from both the blood of dogs and mosquito vectors with no description of cases of heartworm disease in both domestic and wild canines. Here, we report first on two cases of heartworm disease found at post-mortem examination in two roaming dogs from the urban area of Castel Volturno in Campania region of southern Italy. Immunological analyses of 11 roaming dogs from the same pack of those two submitted for necropsy and available necropsy data from the dogs recovered from the Campania region along the past 10 years were both negative for D. immitis infection. Although rare in southern Italy, these two cases are noteworthy because D. immitis may cause serious human infection. We highlight the need to identify the mosquito vectors of heartworm disease in this area using sensitive molecular assay for D. immitis DNA for predicting and controlling the spread of infection. We strongly recommend the control and systematic treatment of the domestic and roaming dogs that could constitute the most important infection reservoir.

Cases of intentional animal poisonings are still widespread in Italy, even if the improper or malicious use of poisoned baits is banned. This represents a serious threat to pets as well as wildlife species, but also an environmental and human health concern. A retrospective study was performed based on baits sent for toxicological analysis to the laboratories of Istituto Zooprofilattico Sperimentale del Mezzogiorno (IZSM) in Southern Italy over a five year period. Analyses were carried out by using different analytical techniques in relation to the toxicants. Results show a trend different from other countries, as well as from that reported for Northern Italy. The molluscicide metaldehyde proved to be the most common substance detected in our laboratory (63.9%) followed by organochlorine insecticides (29.2%), organophosphine insecticides (11.1%) and anticoagulant rodenticides (9.7%). Other rodenticides, such as strychnine and zinc phosphide were detected only one time in baits. Among the organochlorine insecticide, endosulfan (both alpha and beta isomers) occurred as the main poisoning agent. The incidence of poisoning cases detected in the present survey is extremely alarming and pointed out that actions have to be made to reduce this illegal practice and its environmental impact., (Copyright © 2018 Elsevier B.V.

Introduction: Intentional and accidental poisoning of animals is often caused by readily available commercial pesticides, such as the molluscicide metaldehyde. A retrospective analysis of suspected metaldehyde poisonings between 2014 and 2016 in Italy was conducted., Material and Methods: Biological matrices were collected for toxicological analyses in the course of routine Institute activity. A total of 183 organs from dogs and cats and 49 pieces of bait, here specifically poisoned food used to lure animals, were analysed and the presence of metaldehyde was confirmed by gas chromatography coupled to mass spectrometry (GC/MS)., Results: A high content of metaldehyde was demonstrated in the analysed samples from dogs and cats: 50 (27.3%) animals were found positive for metaldehyde intoxication together with 17 pieces of bait., Conclusion: The study emphasised the need for the control of metaldehyde use by the veterinary service., Competing Interests: Conflict of Interests Statements: The authors declare that there is no conflict of interests regarding the publication of this article.
