Ostrich Farming

AbstractOstrich farming serves as a source for meat, feathers, skin, eggs, and oil. In general, ostriches are hardy birds that can resist a wide range of climatic harshness and some diseases. However, musculoskeletal and digestive complications, including the gastric impaction, remain the major cause of mortality. The gastrointestinal impaction alone is responsible for 30 – 46% of spontaneous deaths in growing ostriches. The literature review of 21 publications on this subject has shown that 90% of these incidents happen during first six months of life. The aetiology of this problem is mostly stress and behaviour-related gorging of feed and picking on non-feeding materials such as stone, sand, wood pieces, plastic, glass, and metallic objects. Conservative therapy or surgical approaches show good results with almost 70 to 100% recovery depending upon the clinical presentation and timely diagnosis. Overall, this literature review describes impaction in farmed ostriches, along with diagnosis, treatment, and control and preventive measures. This information will help stakeholders understand the gastrointestinal impaction in ratites to better manage this issue, reduce economic losses, and improve welfare of the birds.

Poult Enteritis

Poult enteritis and mortality syndrome (PEMS) is one of the most significant problem affecting turkeys and continues to cause severe economic losses worldwide. Although the specific causes of PEMS remains unknown, this syndrome might involve an interaction between several causative agents such as enteropathogenic viruses (coronaviruses, rotavirus, astroviruses and adenoviruses) and bacteria and protozoa. Non-infectious causes such as feed and management are also interconnected factors. However, it is difficult to determine the specific cause of enteric disorders under field conditions. Additionally, similarities of clinical signs and lesions hamper the accurate diagnosis. The purpose of the present review is to discuss in detail the main viral possible causative agents of PEMS and challenges in diagnosis and control.

The northern root-knot nematode, Meloidogyne hapla, is a biotrophic parasite that infects many crops and causes severe economic losses worldwide. Rapid and accurate detection of M. hapla is crucial for disease forecasting and control. We developed a recombinase polymerase amplification combined with a lateral flow dipstick (RPA-LFD) assay for rapid detection of M. hapla. The primers and a probe were designed based on the effector gene 16D10 sequence and were highly specific to M. hapla. The RPA reaction was performed at a wide range of temperatures from 25 to 45°C within 5 to 25 min, and the amplicon was visualized directly on the LFD within 5 min. The detection limits of the RPA-LFD assay were 10-3 female and 10-2 J2/0.5 g of soil, which was 10 times more sensitive than the conventional PCR assay. In addition, the RPA-LFD assay can detect M. hapla from infested plant roots and soil samples, and the entire detection process can be completed within 1.5 h. These results indicate that the RPA-LFD assay is a simple, rapid, specific, sensitive, and visual method that can be used for rapid detection of M. hapla in the field and in resource-limited conditions.

Potyviruses are the largest genus of plant viruses that cause significant losses over a wide range of crops. In this paper, the presence of potyvirus in different plant crops in the provinces of Ocaña and Pamplona located in the north and south of the Department of Norte de Santander (Colombia) was evaluated with RT-PCR analysis using universal oligonucleotides specific to the region that encodes the NIB protein. The results indicate the presence of several potyvirus in Pamplona in economically important crops such as corn (Zea mays), tomato (Solanum lycopersicum), potato (Solanum tuberosum) and zucchini (Cucurbita pepo). In Ocaña, potyvirus was found in bean (Phaseolus vulgaris), corn and pumpkin (Cucurbita maxima). In corn, one of the most important crops, the presence of the Sugarcane mosaic virus (SCMV) was confirmed with nucleotide sequencing. This is the first report of this virus in the department. The presence of several potyviruses in different crops in Norte de Santander indicate an alarming phytosanitary condition that must be addressed with priority to establish detection and control systems that maximize production, ensure agricultural sustainability, and propose certification schemes and improvement programs to reduce economic losses.

Multidrug-resistant (MDR) organisms are emerging as some of the main healthcare problems worldwide. During the COVID-19 pandemic, several Infection Prevention and Control (IPC) measures have been adopted to reduce nosocomial microorganism transmission. We performed a case–control study to identify if the incidence of MDR bacterial infections while using pandemic-related preventive measures is lower than in previous years. From 2017 to 2020, we monitored hospital discharges over a four-month period (P #) (1 March to 30 June) in St. Andrea Hospital, Rome. In total, we reported 1617 discharges. Pearson’s chi-squared test was used to identify significant differences. A value of p ≤ 0.05 was considered statistically significant. A significant reduction in the incidence of total MDR bacterial infections was observed during the pandemic compared to in prepandemic years (p < 0.05). We also found a significantly higher incidence of MDR bacterial infections in COVID-19 departments compared with other medical departments (29% and 19%, respectively), with extended-spectrum β-lactamase Klebsiella pneumoniae as the pathogens presenting the highest increase. This study demonstrates that maintaining a high level of preventive measures could help tackle an important health problem such as that of the spread of MDR bacteria.

In the literature review the authors present an analysis of the current stateproblem of ovarian cancer and ways of its possible solution. According to clinicalobservations and conducted in recent decades by morphological,immunohistochemical and molecular genetic studies it is fairly proved that theprimary cause of serous ovarian cancer is the pathology of the mucous layer offallopian tube. In the fallopian tube as a result of ciculation of inflammation andcarcinogens elements arises dysplasia of the mucosa with the development of thepreinvasive and initial invasive carcinoma with subsequent damage of the ovariesand pelvic peritoneum. Retrospective studies of a significant number of women’shealth status who had a deligation or removal of fallopian tubes in previous years showed a decrease in the disease incidence of serous ovarian cancer from 30 to 90%. The conclusions about the possibility of preventive measures of ovariancancer by opportunistic salpingectomy at post-productive age are made. In many world countries (Canada, China, France, Italy, Austria) the introduction of such a method of prevention has been started. We believe that in Ukraine there is an urgent need and all possibilities to solve this problem. Key words: ovarian cancer, preventive measures, opportunistic salpingectomy.

Rot Disease

Charcoal rot disease, caused by the fungus Macrophomina phaseolina, results in major economic losses in soybean production in southern USA. M. phaseolina has been proposed to use the toxin (-)-botryodiplodin in its root infection mechanism to create a necrotic zone in root tissue through which fungal hyphae can readily enter the plant. The majority (51.4%) of M. phaseolina isolates from plants with charcoal rot disease produced a wide range of (-)-botryodiplodin concentrations in a culture medium (0.14–6.11 µg/mL), 37.8% produced traces below the limit of quantification (0.01 µg/mL), and 10.8% produced no detectable (-)-botryodiplodin. Some culture media with traces or no (-)-botryodiplodin were nevertheless strongly phytotoxic in soybean leaf disc cultures, consistent with the production of another unidentified toxin(s). Widely ranging (-)-botryodiplodin levels (traces to 3.14 µg/g) were also observed in the roots, but not in the aerial parts, of soybean plants naturally infected with charcoal rot disease. This is the first report of (-)-botryodiplodin in plant tissues naturally infected with charcoal rot disease. No phaseolinone was detected in M. phaseolina culture media or naturally infected soybean tissues. These results are consistent with (-)-botryodiplodin playing a role in the pathology of some, but not all, M. phaseolina isolates from soybeans with charcoal rot disease in southern USA.

Over the last two decades, experimental economics has been gaining relevance in the research of a wide range of issues related to agriculture. In turn, the agricultural activity provides an excellent field of study within which to validate the use of instruments employed by experimental economics. The aim of this study is to analyze the dynamics of the research on the application of experimental economics in agriculture on a global level. Thus, a literature review has been carried out for the period between the years 2000 and 2020 based on a bibliometric study. The main results show that there has been a growing use of experimental economics methods in the research on agriculture, particularly over the last five years. This evolution is evident in the different indicators analyzed and is reflected in the greater scientific production and number of actors involved. The most relevant topics within the research on experimental economics in agriculture focus on the farmer, the markets, the consumer, environmental policy, and public goods. These results can be useful for policy makers and researchers interested in this line of research.

This study was conducted with the aim of evaluating the role of information and information resources in the awareness, control, and prevention of COVID-19. This study was a descriptive-analytical survey in which 450 participants were selected for the study. The data collection instrument was a researcher-made questionnaire. Descriptive and inferential statistics were used to analyze the data through SPSS. The findings show that a wide range of mass media has become well known as information resources for COVID-19. Other findings indicate a significant statistical difference in the rate of using information resources during COVID-19 based on age and gender; however, this difference is not significant regarding the reliability of information resources with regard to age and gender. Health information has an undisputable role in the prevention and control of pandemic diseases such as COVID-19. Providing accurate, reliable, and evidence-based information in a timely manner for the use of resources and information channels related to COVID-19 can be a fast and low-cost strategic approach in confronting this disease.
