This family is heterogeneous as it consists of about 30 genera of bacteria and more than 100 species. However, all these germs have in common their preferential location in the digestive system, some being part of the normal flora although they are also present in the environment. Several metabolic processes characterize this bacterial family. These include the ability to reduce nitrate to nitrite (for energy generation), ferment glucose, lack cytochrome oxidase, be aerobic or anaerobic, motile or immobile, … Enterobacteriaceae constitute more than 80% of the germs isolated in the laboratory: Escherichia, Salmonella, Shigella, Klebsiella, Enterobacter, Serratia, Proteus, Morganella and Yersinia are the rods most often found. Regarding nosocomial infection to Serratia, this bacterium colonizes the respiratory, digestive and urinary systems of patients, mainly responsible for bacteremia, infections of the lower respiratory tract, urinary and skin infections. Through our work, we report the epidemic experienced in the neonatal intensive care unit MOHAMMED VI university hospital, mother-child hospital MARRAKECH MOROCCO for three months from December at February 2023 interesting 30 newborns whose clinical presentation was different, the positive diagnosis was based on blood and geographical samples taken by the bacteriology department to isolate the offending germs, the therapeutic management of our patients consisted essentially of various hygiene measures in association with dual antibiotic therapy based on meropenem and amikacin. The evolution was marked by the death of 21 patients (70%) and the recovery of 9 patients (30%). The prognosis of infection by serratia remains bleak with high morbidity interest in prevention by respecting the rules of hygiene, which begins with hand disinfection.展开更多

This location is not primary, but follows a primary skin or mucous infection that may go unnoticed. This is a very rare phenomenon in neonatology and in the various literature reviews. Through our observation we report the clinical diagnosis of a newborn 13-day age with pleuro-pulmonary staphyloccocia point of departure cutaneous, thus the paraclinical explorations performed in our patient therapeutic management and evolutionary profile after a 3-month decline. Note that the problem of resistance of staphylococci to different antibiotics is currently a real public health problem making the choice of treatment very difficult for the clinician.展开更多

This pathogen very rarely causes neonatal sepsis. The most common infections caused by Pantoea SPP are septic arthritis or synovitis, meningitis frequently complicated by brain abscess, upper respiratory infections, and peritonitis. We present the case of a premature infant who presented neonatal respiratory distress and whose evolution was complicated by the occurrence of a nosocomial infection for which a blood culture was performed isolating the germ Pantoea SPP. The patient’s management was initially centered on non-invasive ventilation with antibiotherapy based on carbapenem and aminoglycoside. Due to the clinical and biological worsening, the neonate was intubated and sedated and put on colymicin. The evolution was unfavorable marked by a death at 16<sup>th</sup> days of life. Considering the high pathogenicity of this germ and its multi-resistance to antibiotics, it is crucial to know the clinical spectrum of Panteoa SPP infections in neonatal intensive care units, in order to palliate the fulminant evolution of multifocal attacks due to this germ.展开更多

This misidentification has led to a lack of understanding of important clinical and biological aspects of this bacterial species. It is responsible for serious and potentially fatal infections, with a prevalence of multi-resistance to routine antibiotics. We present through three clinical observations, the case of three newborns having been hospitalized in the neonatal intensive care unit and whose evolution was complicated by the occurrence of a nosocomial infection in front of which a blood culture was done on blood agar, with a manual antibiogram on antibiotic disks, isolated the germ Klebsiella variicola. The management of the newborns was initially centered on non-invasive ventilation with a bi-antibiotic therapy based on carbapenem and amikacin for two newborns and switched to colymicin for the third case. Newborn follow-up was based on assessment of general condition, clinical signs of infection, as well as a biological control made of a blood count, a c-reactive protein, a complete ionogram, and a blood culture, every four days or if signs of clinical call. The evolution was favorable for two cases with good clinical and biological improvement, and complicated by death due to alveolar hemorrhage in the third case. Given the high pathogenicity of this germ, and the frequency of misidentification, it is crucial to know the clinical spectrum of Klebsiella variicola infections in neonatal intensive care units, in order to adapt the antibiotic therapy and to mitigate the fulminant evolution of this germ.展开更多
