"Pandemi COVID-19 telah menimbulkan tantangan global dalam menghadapi penyebaran virus SARS-CoV-2. Vaksinasi menjadi strategi efektif dalam mengurangi penyebaran virus dan dampak COVID-19 pada kesehatan masyarakat. Platform vaksin yang banyak diberikan di Indonesia antara lain platform virus utuh dan vektor virus. Penelitian ini bertujuan menganalisis imunitas humoral pasca vaksinasi COVID-19 platform virus utuh dan vektor virus pada orang dewasa. Desain penelitian ini adalah longitudinal dengan pengambilan sampel secara berkala sebanyak 6 kali sebelum dan setelah vaksinasi. Penelitian dilakukan pada tahun 2021 sampai 2023 di Kota Bogor dan Kabupaten Sleman. Jumlah subjek yang terlibat sebanyak 150 orang pada setiap kelompok. Pengumpulan data dilakukan melalui wawancara dan pengambilan sampel serum. Serum diperiksa untuk binding antibody menggunakan CMIA, antibodi netralisasi menggunakan SvNT, subkelas IgG menggunakan ELISA, dan mediator imunitas seluler menggunakan multipleks ELISA. Dari hasil pemeriksaan laboratorium pada sampel TP1 didapatkan sebanyak 42% subjek vaksin virus utuh dan 81% subjek vaksin vektor virus positif antibodi SARS-CoV-2. Di antara subjek yang positif mempunyai riwayat gejala sesak napas (100%), demam (89%) dan pilek (82%). Subjek vaksin vektor virus mempunyai tren respons antibodi lebih tinggi dibanding virus utuh. Proporsi subjek positif pada pengukuran antibodi netralisasi selalu lebih tinggi dibanding binding antibody. Berdasarkan imunosenescence, secara umum tidak berbeda bermakna di antara kelompok usia tersebut. Faktor yang secara signifikan memengaruhi respons imun dalam adalah platform vaksin. Respons antibodi tidak berbeda bermakna pada subjek yang mendapatkan vaksin 2 dan 3 dosis, baik pada hasil pengukuran TP1 positif maupun negatif. Pemberian dosis 3 heterolog menimbulkan respons antibodi yang lebih tinggi dibandingkan dengan homolog. Analisis statistik pada kedua kelompok penerima vaksin menunjukkan tidak berbeda bermakna pada semua subkelas IgG. Kadar IFN gamma, IL-2, IL-6, IL-10 dan TNF alpha pada virus utuh lebih rendah dibandingkan vektor virus Hasil penelitian menunjukkan bahwa kedua platform vaksin mampu menginduksi respons antibodi yang signifikan. Namun, terdapat perbedaan dalam pola dan durasi respons imun antara kedua jenis vaksin.

The COVID-19 pandemic has become a global challenge with the spread of SARS-CoV-2. Vaccination is an effective strategy to reduce the spread of the virus and the impact of COVID-19 on public health. The research aims to analyse humoral immunity following vaccination with COVID-19 viral platforms and viral vectors in adults. The study design is longitudinal, with samples taken periodically up to 6 times before and after vaccination. The study will be conducted between 2021 and 2023 in Bogor City and Sleman District. The number of subjects involved is 150 people in each group. Data will be collected through interviews and serum sampling. Serum was tested for antibody binding using CMIA, antibody neutralisation using SvNT, subclass IgG using ELISA, and cellular immunity mediators using ELISA multiplex. Laboratory testing of the TP1 sample showed that 42% of the whole inactivated vaccine subjects and 81% of the viral vector subjects were positive for SARS-CoV-2 antibodies. Those who were positive had a history of shortness of breath (100%), fever (89%) and colds (82%). The proportion of positive subjects in the neutralised antibody measurement is always higher than the antibody binding. Based on immunosenescence, there is generally no difference in significance between these age groups. The factor that significantly affects the immune response within the vaccine is the vaccine platform. The antibody response was not significantly different in subjects who received 2 and 3 doses of the vaccine, both in positive and negative TP1 measurements. The administration of 3 heterologous doses results in a higher antibody response compared to homologous doses. Statistical analysis in both groups showed no significant difference in all IgG subclasses. IFN gamma, IL-2, IL-6, IL-10 and TNF-alpha levels were lower in the whole inactivated vaccine than in in the viral vector. However, there are differences in the pattern and duration of immune responses between the two vaccines."

"This book describes antibiotic resistance amongst pathogenic bacteria. It starts with an overview of the erosion of the efficacy of antibiotics by resistance and the decrease in the rate of replacement of redundant compounds. The origins of antibiotic resistance are then described. It is proposed that there is a large bacterial resistome which is a collection of all resistance genes and their precursors in both pathogenic and non-pathogenic bacteria. Ongoing resistance surveillance programs are also discussed, together with the perspective of a clinical microbiologist.
The book then turns to specific themes such as the most serious area of resistance in pathogens, namely in Gram-negative organisms. The role of combinations of antibiotics in combating resistance emergence is discussed, particularly in the tuberculosis field, and then the importance of non-multiplying and persistent bacteria which are phenotypically resistant to antibiotics and prolong the duration of therapy of antibiotics which leads to poor compliance and resistance emergence. The role of anti-microbial compounds in textiles is covered, with its potential to exacerbate the spread of resistance. Then, efflux pumps are discussed. The final chapter describes the compounds which are in late stage clinical development, illustrating the paucity of the antibiotic pipeline, especially for Gram-negative bacteria."

"Topically applied products and medications can profoundly affect skin's barrier function and overall health. Bursting with suggestions to assist research and development, Innate Immune System of Skin and Oral Mucosa: Properties and Impact in Pharmaceutics, Cosmetics, and Personal Care Products provides a comprehensive overview on the innate immune system and its relevance to pharmaceutics, cosmetic chemistry, and personal care products. The book allows pharmaceutical and medical professionals to assess accumulated knowledge and develop an understanding that will pave the way for next generation treatment avenues, preventative approaches, and drug development. Part I of this book presents an overview emphasizing mechanisms for control of bacteria at the skin surface. This includes historical and ethical aspects of skin cleaning products.Part II of the book includes chapters discussing antimicrobial peptides and lipids in innate immunity of skin and mucosa. Part III deals with cellular components of innate immunity and the link between innate and adaptive immunity. Part IV deals with stressors that can influence innate immunity. These include radiation and oxidative stress, cosmetic formulations, and aging. Finally, microbial challenges are discussed in Part V."

"Coxiella burnetii is the etiological agent of Q fever, a zoonotic disease found worldwide. The bacterium is a fascinating example of intracellular parasitism that has uniquely evolved to thrive in the most inhospitable of cellular compartments-the phagolysosome. Understanding how C. burnetii resists the degradative functions of this vacuole, and the host cell functions coopted for successful parasitism, are central to understanding Q fever pathogenesis. Recent achievements in glycomics and proteomics are guiding development of enhanced detection schemes for the bacterium in addition to shedding light on the host immune response to the pathogen. Several chapters survey immune functions that control or potentially exacerbate Coxiella infection and delve into correlates of protective immunity elicited by vaccination. Comparative genomics is also the foundation of chapters discussing diagnostic antigen discovery and molecular typing of the bacterium, with significance for development of new clinical, epidemiologic, and forensic tools."
