Diarrhoea represents a significant public health concern worldwide and is responsible for an increase in mortality and morbidity, especially among children but also among adults. Cryptosporidium, one of the most common intestinal protozoan parasites, is the etiological agent of cryptosporidiosis, an acute infection with self-limiting evolution, but that can evolve into severe diarrhoea in children and immunosuppressed hosts. The main species that cause human cryptosporidiosis are C. parvum and C. hominis. Despite the progress made in order to control and monitor cryptosporidiosis at the global level, numerous outbreaks have been reported with the source of infection being food or water. Using Promedmail.org we have performed a review of Cryptosporidium related outbreaks reported in the last 10 years over the world. [ABSTRACT FROM AUTHOR]

Predecessors in the Romanian School of Microbiology established several golden guidelines for the clinical integration of the microbiology laboratory, the clinical rationale behind the infectious disease patients, and the antibiotic administration. However, without a determined mind to continue, strengthen, and nurture the work they have undertaken, professors Ion Cantacuzino, Victor Babes, and Matei Bals' expertise would have vanished [1-3]. Professor Angelescu proved to be the ideal individual right when he was most needed, determined to carry on their legacy, to further advance antibiotic knowledge, and a patient, father-like figure to his younger colleagues. He answered the invitation to become a leading authority at a time when advances in the science of antibiotics had doctors puzzled. The "Angelescu's Guide" was intended to be a lifeline for what would soon become one of the major challenges of the twenty-first century: antibiotic resistance in delicate clinical settings. Actual, achievable strategies for the care of an infectious illness patient are provided below, as are pertinent research recommendations for younger and fresher medical minds.

Despite the global economic development, diarrhoea remains an important health concern worldwide. The epidemiological importance of Shigella spp. infections is very high, being the leading cause of bacterial diarrhoea. Clinically, shigellosis can manifest as watery diarrhoea or dysentery, with bloody stool, accompanied by fever and abdominal pain. Children and the elderly are most susceptible to developing severe forms. In this review, we highlight the rise of antibiotic-resistant Shigella spp. strains and provide an overview of recent shigellosis outbreaks. Shigellosis is an infectious disease that should not be neglected, as evidenced by the many outbreaks reported throughout the world. [ABSTRACT FROM AUTHOR]

Human immunodeficiency virus (HIV) poses a medical, social, and economic problem. In Romania since 2002, the prevention of HIV transmission and the care for HIV-positive people have been overseen by Governmental Law. HIV infection in Romania has some particularities, such as the high number of HIVinfected patients under treatment and the high percentage of long-term survivors. Romania reported its first case of AIDS to the World Health Organization in 1985, and its first case in the pediatric population in 1989. A year later, a new case definition, based on local possibilities was formulated together with the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC, Atlanta, GA). According to the latest report of the Compartment for Monitoring and Evaluation of HIV/AIDS in Romania, the cumulative number of HIV cases registered between 1985-2021 was 26,171, while the number of people living with HIV at the end of December 2021 was 17,271.

Providential personalities have been writing history since the beginning of times - personalities that could be found within and across Romania's borders [1]. In medicine, such brilliant figures have healed patients through diligence, dedication, and professionalism, but have also passed significant teachings to the next generations. They have rigorously respected an authentic professor's definition, a figure that teaches and prepares specialists for the future. The great medical personalities, Ion Cantacuzino and Victor Babeș, have been mentored by famous professors, have also become famous professors on their own, and they have educated doctors and professors who have carried on their research and medical teaching legacies. Through study, through diligence, and an impressive personal development, their students have also become proficient figures in medicine [1-2]. They have trained personalities in the medical field that could have reached higher peaks, were it not for the political and social climate of their country. Among those, now we shall bring into discussion professor Matei Balș, a remarkable man and teacher, whose contribution focused the necessity of employing strict and correct means of practice, tying together in an organic way the clinical and the laboratory work, a dogma which he has passed on to his students. He has funded the "School of Infectious Diseases" at Colentina Hospital and has formulated teachings that stand the test of time; his working approach is still appropriate and praised today. The current generation as well as future ones not only have the obligation to recognise the exceptional achievements of our ancestors in history, but to also keep them alive and develop upon them, in the interest of the Romanian people, Romania itself, but also for the public health system at an international level [1].

One of the main concerns of the medical community during the COVID-19 pandemic has been the management of the immunosuppression accompanying the disease, particularly in ICU (Intensive Care Unit) patients. More recently, the focus has shifted towards the management of the persistent immunosuppression post-acute COVID-19 and its complications. The rate of healthcare-associated infections (HAIs) had been declining before the pandemic, but has since started to increase once more. Due to multiple factors - unnecessary antibiotherapy, disorganized medical facilities, inadequate personal protection equipment etc. - there have been increasing reports of coinfections and secondary infections with multidrug-resistant bacteria in COVID-19 patients. We present a case report of a patient with no history of clinically overt immunosuppression before developing critical SARS-CoV-2 pneumonia. The patient had no need for antibiotic treatment during his hospitalization and was discharged in a stable state, being consequently readmitted multiple times for different healthcare-associated multidrug-resistant infections, over time developing other hospital-related complications. The case raises a discussion about the bidirectional relationship between post-COVID immunosuppression and the possible inadvertent excess in antibiotic therapy that has accompanied the pandemic.

SARS-CoV-2 infection increases the risk of multi-organ systemic complications and venous and arterial thromboembolism. The development of vaccines has proven to be an effective method to combat severe forms of infection. Adverse effects reported after COVID-19 vaccination consisted of local injection site reaction, fatigue, myalgia, or fever as well as sporadic cases of vaccine-induced thrombotic immune thrombocytopenia, especially viral vector vaccines. Objectives: The aim of the study was to evaluate the repeated dose toxicity of a candidate vaccine against SARS- CoV-2, a test in which several parameters were analyzed, including coagulation factors. Materials and methods: The test included 120 rats, of both sexes, divided into six groups (main group, recovery group and control group) at which the human dose, 10X human dose and 1 control adjuvant were tested. The vaccine was administered intranasally, 4 times every two weeks. The final day was after the last administration to the main group and another 30 days from the last administration to the recovery group. On day 0 and the final day, blood was collected for hematological, biochemical, immunological examinations and coagulation tests (Fibrinogen, Prothrombin Time-PT, Activated Partial Thromboplastin Time-aPTT and Thrombin Time-TT). Results: Fibrinogen, in the case of all groups, increased on the final day, except for females from the recovery groups where this parameter decreased by 25%. PT, aPTT and TT, regardless of group or sex, had low values compared to the initial time of the study. On day 0, the values of the coagulation factors were homogeneous, the fibrinogen being between 155- 347mg / dL, PT 25.5-57.8 sec, aPTT 61.9-120 sec and TT values of 53-60 sec. On the final day, the group analysis also showed unit values. Fibrinogen increased between 90-116%, PT decreased by 48-71%, aPTT decreased by 59-80%, and TT had values lower by 10-14% compared to the initial day. Conclusions: Increased fibrinogen associated with decreased PT and aPTT is common in human clinical pathology. Fibrinogen, PT, aPTT and TT are the standard parameters of blood clotting assessed in toxicity tests. The results obtained in the study represent a preliminary phase which, corroborated with the results of the other tests, supports the conclusion that the candidate vaccine does not have toxicological potential, the coagulation factors not being influenced after its repeated administration.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease affecting intertriginous skin areas of young adults. Although HS was historically defined as an infectious disease, the role of microorganisms in its pathogenesis is now controversial. We investigated the lesion microbiota of a recently diagnosed 24-year-old male patient with axillary HS, who shared features of the metabolic syndrome. The microbiological analysis of the patient's lesion was indicative of colonization with bacteria including aerobes - Staphylococcus (S.) aureus, S. lugdunensis, S. epidermidis, anaerobes - Anaerococcus (A.) octavius, and microaerophiles - Cutibacterium (C.) acnes; this last one was also isolated in monoculture from a patient's healthy skin control sample. In vitro antibiotic susceptibility evaluation revealed Methicillin-resistant S. aureus (MRSA) and highly susceptible S. lugdunensis and S. epidermidis. Profiles of A. octavius and C. acnes showed that both strains were susceptible to Vancomycin, Clindamycin, Doxycycline and Linezolid; the anaerobe was Benzylpenicillin-resistant and Tetracycline and the microaerophile was intrinsically Metronidazole-resistant. We conclude that the intralesional microbial diversity in this case shows low variety of species and similarities to healthy skin microbiota, although the presence of S. aureus, particularly MRSA, S. lugdunensis or C. acnes - frequently involved in chronic skin pathologies - may be relevant for the disease severity. MRSA carriage in the patient's lesion represents a significant epidemiological risk for the healthcare environment. Antibiotic treatment in the early stages of HS should be administered with caution. Extended studies of HS microbiota could identify relevant colonization patterns for the outcome of the disease and offer important keys for selecting personalised, efficient therapeutic schemes.
