Abstract

Background: The diagnosis of meningitis in the infancy period is a challenging. Clinical evaluation and high index of suspicion with early empirical treatment guidelines continue to evolve and support physician efforts to decrease the morbidity and mortality associated with pediatric meningitis. Case report: We report a case of a previously healthy 2-month-old male who presented with excessive crying, preceded by subjective fever and watery diarrhea, for one day without any other symptoms. Parents gave multiple antipyretic doses at home for irritability which might mask his fever. The patient was tachycardic with an unremarkable physical exam. Full septic work-up done after stabilization of the patient and empirical antibiotics started. His blood culture grew Neisseria meningitides which caused meningoencephalitis and ventriculitis with bilateral extra-axial collection, the patient was in septic shock with multiple organ dysfunction. Conclusion: Meningococcal meningitis in the neonatal and infancy periods remains a serious health threat with high morbidity and mortality. This case report urges the physician to keep a high index of suspicion by taking detailed history and frequent assessment in each suspected cases as the clinical presentations, signs and symptoms in the infancy period are not specific nor classic to guide the physician.

Abstract

Research has identified certain bio-based products, such as probiotics, as alternatives to antibiotics for use in animal feed. They are capable of controlling, preventing or minimizing the colonization of the gastrointestinal tract by pathogenic bacteria. To isolate Pediococcus spp. and assess its technological properties for possible probiotic development, maize and pearl millet were used. The cereals were steeped and wet milled after 48 h of fermentation. The milled cereals were kneaded into dough for 24 h, after which a 10% slurry was prepared for tenfold serial dilution to enumerate the LAB by employing pour plate techniques using MRS Agar. Based on the cell morphology of the isolated bacteria, eight isolates (four from maize and four from millet) that were selected for identification using MALDI-TOF MS showed that five were Pediococcus pentosaceus (P. pentosaceus), one was Pediococcus acidilactici, and two did not match any organism. Subsequently, the six isolates were labeled as MZ1, MZ2, MZ3, MZ4 for the maize isolate and MLT5 and MLT7 for the millet isolate. The six Pediococcus spp. were assessed in vitro for acid and bile salt tolerance, gastric juice and intestinal fluid tolerance and antibiotic resistance and antimicrobial susceptibility tests were performed, and the survivability rate of the strains was calculated. With regard to the mean count, there was a reduction in log10 CFU/mL under the lower pH conditions and their duration of exposure with regard to time. Among the isolates, no differences were noted at the various periods of exposure (0 h, 1 h, 2 h and 3 h) at pH 4 (p > 0.05). However, significant differences were noted at pH 3, 2 and 1 among the isolates (p < 0.05). The percentage survival of MZ4 and MLT7 at pH 1 was higher compared to the other isolates at 0 h. Significant differences were observed among the isolated at pH 2, 3 and 4 across the various periods. The mean count of the isolates in gastric juice was similar at 0 and 1 h, but significant differences were noted at 2 and 3 h, where MLT7 was highest (p < 0.05). A similar trend was observed for percentage survival. The mean count and the percentage survival of isolates under different concentrations of bile salt were similar. Significant differences were noted among isolates in both mean count and percentage survival when exposed to intestinal fluid (p < 0.05). All of the isolates were highly tolerant to the antibiotics tested and possessed antibacterial properties against the selected pathogens. The LABs proved to be good probiotic materials, according to the results obtained. However, the Pediococcus strain MLT7 proved to be the LAB of choice; therefore, its molecular identity was verified using the 16S rRNA sequence and was labeled as Pediococcus pentosaceus GT001 after it was discovered to have 100% similarity with some strains of Pediococcus pentosaceus.
