Bovine cysticercosis is a parasitic infection of cattle caused by the human tapeworm Taenia saginata. Bovine cysticercosis was identified by meat inspection in 4.7 per cent (18 out of 380) of the cattle submitted for slaughter, over an 8-month period, from a beef finisher farm. This value is significantly higher compared with the 2019 annual rate of detection from England meat inspection data, which was 0.018 per cent. Two of the 18 carcases were condemned on the grounds of generalised bovine cysticercosis. Its involvement was investigated by histopathological examination and confirmed using PCR and sequencing. Animal and Plant Health Agency collected data regarding the feed, the source of livestock, the staff sanitary conditions, the husbandry system, management and the farm environment. The results indicated that the permanently housed cattle were most likely infected on the finisher unit by homemade grass silage produced from a field which was crossed by a public footpath and bordered by two camp sites.

Background: Soil-transmitted parasites (STPs) are significant intestinal parasites that infect humans and animals and impose considerable burdens on human society and animal husbandry industries. Therefore, the present study aimed to determine the prevalence of parasitic elements of soil samples collected from the north of Iran. Methods: A total of 256 soil samples were collected from public parks, public places, vegetable gardens, sand heaps, and shadow areas near houses in the north of Iran and examined using the sucrose flotation method. Results: Out of 256 examined samples, 131 (51.2%) ones showed parasitic contamination including larvae (43%), oocysts (14.1%), and different eggs (6.6%). According to the results, the most and least common parasites observed in the samples were larvae (43%), as well as Toxascaris leonina, and Trichuris trichiura (0.4%), respectively. Moreover, the most and least contaminated locations were sand heaps (62.5%) and shadow areas near houses (45.6%), respectively. Regarding cities, Behshahr (68.3%) and Sari (67.5%) had the highest contaminated soil samples, whereas Chalus (37.5%) showed the lowest contamination. On the other hand, rural samples showed more contamination, compared to urban areas (P< 0.05). Conclusion: The findings of the present study indicate that the overall prevalence of STPs in examined areas and highly contaminated soil samples can be considered as a potential source of human contamination particularly tourists with STPs.

Oil and Gas (O&G) platforms in the North Sea are facing aging problems as many of the installations have matured and are approaching their design lifetime. Flowlines are used to transport oil and gas well stream from the wellhead to the production manifold. They are categorised as one of the most critical components on a production facility. Flowline degradation takes place due to corrosion and erosion. The deterioration of a flowline may increase the risk of leakages, ruptures, etc., which shall lead to serious HSE (health, safety and environmental) and financial consequences. Any such risks have a direct impact on the O&G installation’s technical integrity as well as the operator’s sustainability concerns. Conventionally, pipelines are designed with safety provisions to provide a theoretical minimum failure rate over the life span. Furthermore, to reduce the risk of failure various techniques are routinely used to monitor the status of pipelines during the operation phase. The existing methods of flowline health monitoring planning requires one to take into consideration the operator’s plant strategy, flowline degradation mechanisms, historical data, etc. A technical condition report is made based on findings’ reports and degradation trends. This report recommends the inspection of a number of points on the flowlines in a certain year using non-destructive evaluation methods such as visual inspection, ultrasonic testing, radiographic testing, etc. Based on the technical condition report, in general for a certain preventive maintenance shutdown, 10 to 15 flowline inspection openings are accommodated as finance, time and resource availability are taken into consideration. However, it is customary to plan to open more locations in a certain inspection package than can be inspected and minimization of such points is at present done on an ad hoc basis. This paper suggests a formal model and a framework to formally minimize the number of visual inspections by executing the plant strategy as well as HSE concerns. The model is derived using analytic hierarchy process (AHP) framework, which is a multi-criteria decision-making approach. The model is developed based on literature, industrial practice, experience as well as real inspection data from a mature offshore O&G installation located on the Norwegian Continental Shelf.

Epidemiological Characteristics

Abstract Background Oculosporidiosis (ocular rhinosporidiosis) accounts for 15% of cases of rhinosporidiosis, which is a chronic granulomatous disease and is endemic in India and Sri Lanka. In Brazil, the climatic and hydrographic similarities to these endemic areas and the presence of riverside populations contributes to an increase in the incidence of rhinosporidiosis particularly in the State of Maranhão. This study, therefore, aimed to identify the number of diagnosed cases of oculosporidiosis and describe its the clinical epidemiology, laboratory, histopathology, and therapeutic characteristics. Methods The study is descriptive, observational, and cross-sectional, and reports the prevalence and clinical epidemiological characteristics of oculosporidiosis in the State of Maranhão, Brazil. A retrospective analysis of the paper and electronic records for a period from 1999 to 2017 was conducted in the University Hospital of Federal University of Maranhão (HU-UFMA), located in the northeastern region of Brazil. Results Thirty patients were diagnosed with rhinosporidiosis, eight of them had oculosporidiosis and seven of these met the criteria to be included in the study. Of the cases (23.3% of all 30), five were men (71.4%) and two women (28.5%), with an average age of 16.4 ± 15.6 years. In terms of race, four patients (57.1%) declared themselves white and three (42.9%) as brown. The north of the state, the mesoregion, had the most diagnosed cases accounting for 57.1% of the total. Left eye was the most affected site, reported in six patients (85.7%), while the conjunctiva was affected in all patients. Rhinosporidiosis and papilloma were the predominant diagnostic hypotheses (28.5 and 28.5%, respectively), followed by chronic scleritis, granuloma, and chalazion (14.25, 14.25, and 14.25%, respectively). All these cases were treated with lesion excision, and only two patients (28.5%) progressed with recurrence. Conclusion It was verified that there was a male predominance, with only one eye reported as an infected site, with no bilateral involvement. The younger age group (between 1 and 2 years of age) was more affected by oculosporidiosis, and histopathological examination was necessary for a conclusive diagnosis.

Abstract Schistosomiasis is a serious parasitic infection affecting millions worldwide. This study aimed to explore the anti-schistosomal activity of curcumin and curcumin loaded gold-nanoparticles (Cur-GNPs) with or without praziquantel (PZQ). We used six groups of the C57BL/6 mice in which five groups were infected with Schistosoma Mansoni (S. mansoni) cercariae and exhibited, separately, to different treatment regimens of curcumin, curcumin loaded nanoparticle, and PZQ, in addition to one untreated group which acts as a control. Mice were sacrificed at the 8th week where both worms and eggs were counted in the hepatic and porto-mesenteric vessels in the liver and intestine, respectively, in addition to a histopathological examination of the liver granuloma. Curcumin caused a significant reduction in the worms and egg count (45.45%) at the 3rd week. A significant schistosomicidal effect of PZQ was found in all groups. Cur-GNPs combined with PZQ 97.4% reduction of worm burden in the 3rd week and the highest reduction in the intestinal and hepatic egg content, as well, besides 70.1% reduction of the granuloma size. The results suggested the curcumin in combination with PZQ as a strong schistosomicidal regimen against S. mansoni as it alters the hematological, biochemical, and immunological changes induced.

There is increasing interest in utilizing meat inspection data to help inform farmers of the health and welfare of their herds. The aim of this study was to determine whether ante-mortem measures of welfare in beef and dairy cattle (N = 305) were associated with post-mortem measures at a United Kingdom (UK) abattoir. Multiple regression analysis was used to determine the ability of ante-mortem measures of lameness, cleanliness, skin lesions, hair loss and body condition in predicting hot carcass weight and the frequency of carcass bruising. For beef cattle, lameness score (p = 0.04), cleanliness score (p = 0.02) and age (p < 0.001), were predictors of carcass bruise score while lameness score (p = 0.03), body condition (p = 0.01) and sex (p < 0.001) were predictors of hot carcass weight. For dairy cattle, sex (p < 0.001) and slaughter day (p < 0.001) were predictors of carcass bruise score while skin lesion score (p = 0.01), body condition (p < 0.001), age (p < 0.001), slaughter day (p < 0.001) and number of moves (p = 0.01) were predictors of hot carcass weight. These results suggest that recording carcass weight and carcass bruising at meat inspection may have potential as a general indicator of health and welfare status in cattle. However, animal characteristics and variables, such as slaughter day and abattoir staffing, should be taken into account when interpreting the results.

Public health agencies undertake a broad range of health promotion and injury and disease prevention activities in collaboration with an array of actors, such as the community, businesses, and non-profit organizations. These activities are “multisectoral” in nature and centered on public health agencies that oversee and engage with the other actors. Public health agencies can influence the hazardous activities in the private sector in a variety of ways, “ranging from prohibition and regulation to volunteerism, and from cooperation to cooption.” Hence, a public health agency that possesses the necessary administrative resources and authority is vital to the effective implementation of health policies and regulations.In the developing world, however, many state health agencies lack these basic capacities in dealing with critical health threats, including their ability to avert epidemics of communicable diseases arising from poor sanitary conditions. A serious constraint is the shortage of public health funding for health agencies in the developing world for typical agency functions (e.g., surveillance, monitoring, assessment, and intervention). This is often aggravated by the transaction-intensive demands entailed in enforcing regulations among an array of private and public sector actors including individuals, businesses, and local bodies responsible for providing civic services.

Abstract. Desrina, Prayitno S B, Haditomo A H C, Latritiani R, Sarjito S. 2020. Detection of Enterocytozoon hepatopenaei (EHP) DNA in the polychaetes from shrimp ponds suffering white feces syndrome outbreaks. Biodiversitas 21: 369-374. Enterocytozoon hepatopenaei (EHP) is the newly emerging pathogen of farmed shrimp in Asia. EHP was associated with white feces syndrome (WFS) in shrimp because the spores existed in the feces of shrimp with WFS. Polychaetes are benthic invertebrates and potential to contribute to EHP outbreaks in a pond by acquiring the pathogen and transfer it to shrimp upon feeding. The objective of this study was to determine (1) the occurrence of EHP in polychaetes with Giemsa staining of the coelomic fluid, 1-step PCR and histopathology and (2) to determine pathological changes of EHP infected tissues. Polychaetes were obtained from 20 shrimp ponds located in 9 districts along the North Coast of Java Island, Indonesia. There were no EHP spores detected in the stained coelomic fluid. The 1-step PCR analysis was able to detect the EHP DNA (prevalence was 10%). The Alignment of EHP DNA sequence found in polychaetes showed 100% identity with a published sequence. Histopathological examination showed hypertrophy cells and nuclei, however, no EHP mature spores were found in the epithelial cells on the mucosal layer of the stomach and intestines. Although methods used did not give the convergence results, however, a result of PCR and sequence analysis showed that EHP occurred in the polychaetes in the WFS infected ponds at low point prevalence.
