In our country a certain number of wild boars is controlled and reared on enclosed hunting ground, while a number of free-ranging population is mainly unknown. The control of health status of wild boar population is quite demanding and it is not easy to achieve. Also, often is not possible entirely to perform a complete diagnostic examination in wild boars in each evaluated case. The aim of this research was to evaluate the clinical signs and pathomorphological changes in the suspicious cases on the occurrence of the verminous pneumonia in wild boars. The material for this research included three hunting grounds in Vojvodina, where clinical signs of health disorders and dead of young categories of wild hoags were recorded. The following research methods were applied: epidemiological, clinical and pathological examination of dead wild boars, hystological examination of the lung tissue samples and parasitologial examination. In all examined cases, macropathogical examination revealed changes dominantly in the respiratory tract. By pathohystological and parasitological examination the presence of lung worms in the trachea, bronchi and in posteroventral parts of the diaphragmatic lung lobes were detected (Pneumonia verminosa). In conslusion, the achieved results strongly suggest that Metastrongylus sp. represent economically important helmintosis of wild boars in our climatic conditions. Discovered parasitic infestations in the evaluated wild boars are economically significant because of retardation in the growth and weigh gain, and may be the cause of dead or discarding the meat in the case of cachexia, hydremia.

ABSTRACT: Forty 1-2-y-old water buffaloes were simultaneously treated with trichlorfon and chlorpyrifos products in the recommended dose for cattle. After a week, 19 animals started presenting clinical signs characterized by apathy, diarrhea, aggressiveness, dehydration, and motor incoordination, followed by flaccid paralysis and permanent lateral recumbency. All affected buffaloes died after a clinical course of 1-4 days. Reduction of serum cholinesterase activity in three cases was indicative of significant exposure to organophosphorus compounds (OPs). Pathological examination of three buffaloes revealed no gross and histological lesions. By thin layer chromatography, chlorpyrifos residues and trace of trichlorfon residues were detected in fresh tissue samples. The epidemiological, clinical, pathological, and toxicological findings were highly compatible with OPs-induced delayed neurotoxicity, a neurological manifestation rarely described in domestic animals.

Porcine circovirus 3 (PCV3) is a recently discovered member of the Circoviridae family. So far, its presence has been reported in North America, Asia, South America, and Europe. In this study, blood and tissue samples from 189 Sardinian suids (34 domestic pigs, 115 feral free ranging pigs, and 39 wild boars) were used to genetically characterize the PCV3 strains from Sardinia. PCV3 infection in the animals was confirmed by real time PCR. The detection rate in the three groups analyzed was l7.64% in domestic pigs, 77.39% in free ranging pigs, and 61.54% in wild boars. Moreover, our results showed that co-infection of PCV3 with other viruses is quite a common occurrence. Molecular characterization of Sardinian PCV3 strains was performed by sequencing 6 complete genomes and 12 complete cap genes. Our results revealed that there is a high similarity between our strains and those identified in different countries, confirming the genetic stability of PCV3 regardless of geographical origin. Haplotype network analysis revealed the presence of 6 whole genomes or 12 unique ORF2 haplotypes and a nonsynonymous mutation in ORF2 that leads to an R14K amino acid substitution. Phylogenetic analysis of whole genome and ORF2 was also conducted. The Sardinian strains were allocated in three different clusters of phylogenetic trees of both complete genome and ORF2. With this study, we have provided a snapshot of PCV3 circulation in Sardinia. Our findings might help to achieve a deeper understanding of this emerging porcine virus.

Salmonella spp. is an important zoonotic agent. Wild boars might host this pathogen in the intestinal tract and might represent a risk for Salmonella spp. transmission to humans. Wild boars are widely spread in Liguria, due to the environmental characteristics of the region. The aim of the study was the isolation, typing, and investigation of antimicrobial susceptibility of the isolated strains of Salmonella spp. During the 2013–2017 hunting seasons, 4335 livers of wild boars were collected and analyzed for the presence of Salmonella spp. A total of 260 strains of Salmonella spp. were isolated and characterized, with a prevalence of 6%. The isolated strains belonged to all six Salmonella enterica subspecies. Most of them were identified as Salmonella enterica subs. enterica of which 31 different serotypes were identified. The dominating serotype identified was S. Enteritidis. The antimicrobial resistance profiles of the isolated strains were analyzed against sixteen molecules. Of the isolated strains, 94.6% were resistant to at least one of the tested antimicrobials. This study showed the circulation of resistant Salmonella spp. strains in the wild boar population living in this area of Italy, underling the potential risk for these animals to disseminate this pathogen and its antimicrobial resistances.

Summary Objective: In the present study various tissues of pigs were investigated for the presence of histopathologic lesions after an experimental infection with Haemophilus (H.) parasuis serovar 5. Material and methods: Conventional pigs (n = 36) were divided into a control group B (n = 9) and a challenge group A (n = 27), which was infected intratracheally. Pigs that did not die prior to study termination were euthanized on day 14 post inoculation. Postmortem samples of the lung, heart, liver, kidney, spleen, left tarsal joint capsule and brain were collected. Results: All but one pig with detectable histopathologic lesions (n = 11) showed typical macroscopic changes. Histopatho logic examination of all tissue samples identified pyelitis (n = 10), synovitis (n = 7) and meningitis (n = 7) and all those animals were euthanized prior to study termination. No histopathologic lesions were found in pigs of the control group. The correlations between pyelitis and meningitis, pyelitis and synovitis and synovitis and meningitis were significant (p < 0.001). No significant correlation could be observed between the histopathologic and the clinical examination of the joints. The investigation of samples from the joints by PCR was not significantly correlated with the observed synovitis. The clinical observation of neurologic signs was significantly correlated with meningitis (p = 0.03). A significant correlation (p < 0.001) could be detected between meningitis and the detection of H. parasuis by PCR in brain samples. Conclusions: H. parasuis constantly causes clinical signs and pathologic lesions as soon as it infects the brain while it can infect the joints without causing histopathologic lesions. Pigs with histopathologic lesions do not always show typical clinical signs. Only few studies described the finding of kidney lesions in pigs with Glässer’s disease and this is the first study to describe a pyelitis in pigs experimentally infected with H. parasuis. The observed pyelitis mainly occurred in acute cases.

Abstract The research aimed at evaluating the epizootic and epidemiological situation of trichinosis during the last 8 years in Lublin province on a background of progressing increase in wild boar population within the region and in the whole country. Data for the study were taken from the report on the results of the official examination of slaughter animals and meat, poultry, game, lagomorphs and aquaculture animals and six reports on the number of trichinosis cases found at wild boars and domestic swine. In order to evaluate the trichinosis epidemiological situation within the region, reports of the National Institute of Public Health-National Institute of Hygiene on the number of identified trichinosis cases in people, as well as the number of hospitalised patients were presented. In addition, information on the population and hunting achievement of wild boars in hunting circuits of Lublin province during the last 8 years was enclosed. The number of identified trichinosis cases in meat of wild boars from Lublin region increased 9 times, while the percentage of trichinosis occurrence in reference to the number of examined carcasses almost 3-fold. At the same period, the number of porcine carcasses, in which trichinosis was found, decreased by over 4 times. Over double increase in wild boar population on the studied area was observed during the evaluation. Dynamic increase in the population size - in an aspect of the species population interaction with the living habitat, and in the form of the increase in the number of damages of crops and cultivation fields - contributed to intensified hunting pressure towards the species expressed as almost 3-fold increase of wild boar hunting. Analysis of epizootic and epidemiological situation of Poland indicates that wild boar meat was the principal source of trichinosis during the studied period. Considering Lublin province, the number of identified trichinosis cases is still high as compared to eastern and central provinces. Meanwhile, when compared to western and northern Poland, the level of trichinosis invasion can be considered as low. Furthermore, the trichinosis morbidity among people, that does not exceed 0.18/100 thousand inhabitants, can be regarded as low. Nevertheless, the fact of underestimating the necessity of both wild boar’s and swine’s meat examination seems to be alarming

Abstract Background African swine fever (ASF), caused by the ASF virus (ASFV), was first reported in Vietnam in 2019 and spread rapidly thereafter. Better insights into ASFV characteristics and early detection by surveillance could help control its spread. However, the pathogenicity and methods for early detection of ASFV isolates from Vietnam have not been established. Therefore, we investigated the pathogenicity of ASFV and explored alternative sampling methods for early detection. Results Ten pigs were intramuscularly inoculated with an ASFV strain from Vietnam (titer, 103.5 HAD50/mL), and their temperature, clinical signs, and virus excretion patterns were recorded. In addition, herd and environmental samples were collected daily. The pigs died 5–8 days-post-inoculation (dpi), and the incubation period was 3.7 ± 0.5 dpi. ASFV genome was first detected in the blood (2.2 ± 0.8) and then in rectal (3.1 ± 0.7), nasal (3.2 ± 0.4), and oral (3.6 ± 0.7 dpi) swab samples. ASFV was detected in oral fluid samples collected using a chewed rope from 3 dpi. The liver showed the highest viral loads, and ear tissue also exhibited high viral loads among 11 tissues obtained from dead pigs. Overall, ASFV from Vietnam was classified as peracute to acute form. The rope-based oral fluid collection method could be useful for early ASFV detection and allows successful ASF surveillance in large pig farms. Furthermore, ear tissue samples might be a simple alternative specimen for diagnosing ASF infection in dead pigs. Conclusions Our data provide valuable insights into the characteristics of a typical ASFV strain isolated in Vietnam and suggest an alternative, non-invasive specimen collection strategy for early detection.

Effective Laxative

Senna and its main components sennosides are well-known effective laxative drugs and are used in the treatment of intestinal constipation in the world. Their potential side effects have attracted more attention in clinics but have little scientific justification. In this study, senna extract (SE), sennosides (SS), and sennoside A (SA) were prepared and used to generate diarrhea rats. The diarrhea rats were investigated with behaviors, clinical signs, organ index, pathological examination, and gene expression on multiple aquaporins (Aqps) including Aqp1, Aqp2, Aqp3, Aqp4, Aqp5, Aqp6, Aqp7, Aqp8, Aqp9, and Aqp11. Using qRT-PCR, the Aqp expression profiles were constructed for six organs including colon, kidney, liver, spleen, lung, and stomach. The Aqp alteration profiles were characterized and was performed with Principle Component Analysis (PCA). The SE treatments on the rats resulted in a significant body weight loss (p < 0.001), significant increases (p < 0.001) on the kidney index (27.72%) and liver index (42.55%), and distinguished changes with up-regulation on Aqps expressions in the kidneys and livers. The SS treatments showed prominent laxative actions and down regulation on Aqps expression in the colons. The study results indicated that the SE had more influence/toxicity on the kidneys and livers. The SS showed more powerful actions on the colons. We suggest that the caution should be particularly exercised in the patients with kidney and liver diseases when chronic using senna-based products.

CONTEXT: A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specific, and anterior cruciate ligament ganglia are usually diagnosed through magnetic resonance imaging or arthroscopy. Not all ganglia diagnosed through magnetic resonance imaging need to undergo surgical treatment: only those that cause clinical signs and symptoms do. Surgical results are considered good or excellent in the vast majority of cases. CASE REPORT: A 29-year-old male presented with pain in the left knee during a marathon race. Physical examination revealed limitation in the maximum range of knee extension and pain in the posterior aspect of the left knee. Radiographs of the left knee were normal, but magnetic resonance imaging revealed a multi-lobed cystic structure adjacent to the anterior cruciate ligament, which resembled a ganglion cyst. The mass was removed through arthroscopy, and pathological examination revealed a synovial cyst. Patient recovery was excellent, and he resumed his usual training routine five months later.
