A total 48 chickens from 4 backyard poultry breeds with the clinical presentation of S. enterica infection were randomly selected from villages in the Punjab Province. Cloacal swabs from live poultry and liver samples from the dead birds were collected for bacterial culture and biochemical identification. Liver and spleen samples from dead birds were evaluated for gross and histopathological changes. Bacterial isolates were subjected to PCR and sequencing of ratA gene. Biochemical identification revealed 5/48 (10.42%) chickens positive for S. enterica. Gross pathology included enlarged, discoloured and congested liver and congested spleen. Histopathology demonstrated congestion of sinusoidal capillaries, cellular swelling and cellular/ballooning degeneration, congestion of central hepatic vein, granular hepatocytic cytoplasm and the presence of variable-sized vacuoles in hepatocytes. The PCR yielded a S. enterica specific amplicon (1047 bp). All liver samples that were positive for S. enterica by biochemical tests, were also positive by PCR. The ratA gene sequencing revealed a close resemblance with S. enteritidis isolates from humans. The present study highlights zoonotic risk from backyard poultry and suggests that PCR can be used as an alternate method for rapid detection of Salmonella serovars.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isolates were confirmed both by biochemical testing and a multiplex PCR targeting alpha, beta and epsilon toxin genes of C. perfringens. While 10% (4/40) of the samples were positive for C. perfringens alpha toxins, 17.5% (7/40) of the samples were positive for the alpha toxin gene. The present study indicated that the samples collected from the local butcher shops were contaminated with C. perfringens and its toxins.

These cells, which easily adapt to rapid and continuous growth in the appropriate cell culture environment, are thought to be one of the effective methods in the investigation of leg diseases that are frequently observed in poultry. Leg diseases, especially affecting the joints in chickens, cause locomotor problems and adversely affect animal welfare. In addition, they cause significant health problems and increase mortality. It is known that synovial fibroblasts play an important role in joint diseases. In this study, chicken embryonic synovial fibroblasts were isolated from tissue explants taken from the tibio-metatarsal joint region of brown layer chicken embryos. Characterization of cells was evaluated by immunocytochemistry and hemacolor staining. chicken embryonic synovial fibroblasts showed a strong positive reaction to the vimentin antibody. As a result of hemacolor staining, it was noted that the cell morphology was spindle-shaped. The absence of macrophages in chicken embryonic synovial fibroblast culture was confirmed by the carbon powder uptake. In this present study, we aim to present a useful cell culture protocol such as primary culture, passage, and characterization suitable for chicken embryonic synovial fibroblast to be used in the new scientific research.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The animals were divided into six equal groups. Animals in the control group (n = 10) did not receive any treatment. The animals in the experimental group were administered Ivermectin [three times a week, n = 10, subcutaneous, (SC)], Tarantula cubensis extract (twice a week, n = 10, SC), autologous vaccine (three times at 10-day intervals, n = 10, SC), levamisole [twice at one-week intervals, n = 10, intramuscular (IM)], and levamisole + Tarantula cubensis extract (concurrently). All animals used in the study were monitored for three months at an interval of 15 days. No regression was detected in the papillomas of the control group animals, but recovery was recorded in animals treated with ivermectin at a rate of 70% (7/10), while it was 60% (6/10) in those treated with T. cubensis extract, 100% (10/10) in those treated with autovaccine, 50% (5/10) in those treated with levamisole, and 90% (9/10) in those treated with the combination of T. cubensis extract + levamisole. Significant differences were found between the control group and all treatment groups. Recovery mostly occurred within 45-60 days (P < 0.05).

RNAemia peaked at day 7 post infection in all calves and remained relatively stable till the end of the study, at 78 days post infection. Infectious virus was isolated up to 21 days post infection in one calf. As far as small ruminants are concerned, one sheep experienced fever and two out of five had consistent RNAemia that lasted until the end of the study. Remarkably, infectious virus was evidenced at day 7 post infection in one sheep. In goats, no RNA was observed. All infected animals seroconverted, and a neutralizing immune response was observed in all species, with calves exhibiting a more robust response than sheep and goats. Our study provides insights into the kinetics of EHDV-8 infection and the host immune responses. We also highlight that sheep may also play a role in EHDV-8 epidemiology.

Currently, there is scarcity of information on JEV infection in pigs in Nigeria. Since the Culex tritaeniorhynchus vector of JEV is present in Nigeria and considering recent anecdotal reports of abortions and birth of weak piglets in some pig farms in southwestern Nigeria, there is a need for studies on the presence of the virus and its true burden among pig populations in the country. Serum samples (n=368) obtained from farm-reared pigs in four States of southwestern Nigeria were screened for JEV-specific IgG antibodies using a commercial ELISA kit. An overall JEV seropositivity of 35.1% (95% CI: 30.18 - 39.93%) was obtained, with detectable antibodies in pigs of all age groups, breeds, sex, and locations. Our results suggest natural exposure of these unvaccinated intensively reared pigs to JEV circulating silently in the swine population with significant association of the seropositivity with location (state/community in which the pig farms exist) and breed of the pigs studied. This first report of detection of anti-JEV antibodies in pigs in Nigeria indicates that JEV circulated among these pigs and underscores the need for active surveillance for JEV in humans, pigs, and mosquitoes to provide valuable epidemiological data for the design of effective control strategies against the virus, thus forestalling potential future outbreaks of the infection.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140959925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
