Postpartum uterine diseases, such as puerperal metrity and clinical endometritis can affect more than 40% of cows in dairy farms. Whatever their severity, these diseases are one of the main reasons for fertility loyalty, causing declines in the productivity of dairy cows and therefore leading to economic losses. Although uterine diseases have been the subject of scientific discussion for many years, but it was not possible to agree on uniform definitions for different types of events. Including technical innovations and testing procedures, enormous scientific progress and more in-depth knowledge of physiology as well as pathological mechanisms have been achieved. Bovine metris and endometritis can be considered multifactorial diseases caused by a combination of microbial infection, immune system dysregulation and additional risk factors.
These interactions were analyzed on microbial and molecular biological levels as well as the use of bioinformatics and molecular genetics. As a result, new species of bacteria and inflammatory mediators possibly contribute to the development of uterine diseases have recently been described. In addition, metabolic and genetic risk factors and roles due to fertility deficiency have been evaluated. In conclusion, it was possible to identify new approaches for possible therapeutic and preventive methods, of which a subset can already be implemented in a daily practical routine. This article provides an overview of recent scientific results for bovine metritis and endometritis with a focus on microbial, microbiological and immunological studies.
Comparison of student performances by evaluation through a structured practical examination objective with respect to the conventional method of the second year of MBB students in microbiology
Introduction: The structured practical examination (OSPE) is a complete evaluation tool. We wanted to improve our evaluation methods and make it a more skill-based assessment. Thus, this study was designed to compare the effectiveness of the practical review of the structured objectives with that of the conventional practical examination.
Methods: This interventional study was conducted in the Atciimsh Microbiology Department, Lucknow over six months from October 2019 to March 20, 2019. A hundred MBB students of the year were registered. Students were divided into two offulty groups for the conventional review group (controls) and the OSPE group. The first day, the cases appeared for the OSPE while the conventional examination checks. On the second day, the groups were crossed. Students appearing for the Ospewere evaluated by their scores in different stations. The feedback forms with a pre-tutored questionnaire were given to students and examiners after OSPE two days to record their perceptions. Finally, students’ scores have been tabulated and compared. Microsoft Excel and SPSS were used for data analysis. The data were presented in percentages, average and standard deviation. The T test student was used and the meaning has been verified using the value p <0.05.
Results: Overall, in the OSPE, students marked higher and the result was statistically significant. The proportion of students in the upper brand range was more for OSPE Typethat for the conventional method. The difference was statistically significant (p <0.001) .Feedback taken from examiners as well as students in the form of remote-controlled questionnaire to analyze their perceptions was very encouraging.
Conclusions: OSPE is a complete evaluation modality for the practical assessment of MBBS students. OSPE has been an effective tool that improved the forms of microbiology students.

Anatomical graduate in the microbiology of the merger of the spine infection and resistance to surgical antimicrobial prophylaxis
Study design: Hospital retrospective study-register.
Objective: To characterize the microbial epidemiology of surgical site infection (SSI) in the surgery of the vertebral column melting ad the charge of the standard surgical antibiotic prophylaxis resistance.
Summary of basic data: SSI persists as a state-of-the-art complication of spine melting surgery despite the growth of improved recovery programs and improvements in other surgical measurements. Improved understanding of SSI microbiology and common mechanisms for current prevention strategies are required to inform the development of new prevention approaches relevant to modern surgical practice. Methods: The melting cases of the spine carried out at a single reference center between January 2011 and June 2019 were reviewed and the SSI cases meeting the national health care system criteria were identified. Using microbiological and procedural data for each case, we analyzed the anatomical distribution of pathogens, their differential time on presentation and correlation with staphylococcus filtering results resistant to methicillin. The susceptibility of isolates grown from each infection has been compared to the spectrum of the surgical antibiotic prophylaxis administered during the index procedure on a case-by-case basis. The susceptibility to alternate prophylactic agents has also been modeled.
Results: Of 6727 cases, 351 infections took place within 90 days. An anatomical gradient of the microbiology of SSI has been observed on the length of the back, passing from the cutaneous flora (gram-positive) in the cervical column with the enteric flora (gram-negative / anaerobic) in the Lumbosacrale region (coefficient of Correlation 0.94, p <0.001). The majority (57.5%) of infections were resistant to prophylaxis administered during the proceedings. Cephalosporin-resistant gram-negative infection was common at the LUMBOSACRAL levels and unsecured methicillin resistance was common at the cervical levels.
Description: Trimethoprim-13C3is the deuterium labeledTrimethoprim(HY-B0510)[1]. Trimethoprim is a bacteriostatic antibiotic and an orally active dihydrofolate reductase inhibitor. Trimethoprim is active against a wide range of Gram-positive and Gram-negative aerobic bacteria. Trimethoprim has the potential for the research of urinary tract infections, Shigellosis and Pneumocystis pneumonia. Trimethoprim can inhibit infection of Influenza A virus in chick embryo when combinated with zinc[2][3][4][5].

Endogenous contamination of the wound with an enteric flora can be a common mechanism of infection in the bulging melting. New approaches to prophylaxis and prevention should be priorities in this population.
