We describe an elderly male who had a two day history of fever, abdominal pain and watery loose motions. Clinical examination was positive for abdominal right lower quadrant tenderness and moderate dehydration. Stool examination revealed inflammatory diarrhea. Considering the high prevalence of extended spectrum beta-lactamases (ESBL) producing Gram-negative infections, he was treated with Piperacillin/Tazobactam. Surprisingly, his blood culture which was taken on admission returned positive for Streptococcus pneumoniae after two days, which was coincident with resolution of fever and diarrhea. This patient had no other clinically apparent source of Pneumococcal infection and we believe that he had Pneumococcal enteritis with bacteremia. There are very few reported cases of isolated Pneumococcal enteritis in the literature. Therefore, we report this unusual form of Streptococcus pneumnoniae infection both because of its rarity and its potentially life-threatening but still curable nature.

Impact of Immunosenescence on Vaccine Immune Responses and Countermeasures.
Vaccines (Basel)
November 2024
School of Public Health, Southeast University, Nanjing 210096, China.
Article Synopsis
- Aging affects our body's functions, leading to weakened immune responses and higher vulnerability to diseases, known as immunosenescence.
- This review focuses on how immunosenescence impacts the effectiveness of vaccines for older adults, particularly for common viruses like COVID-19 and influenza.
- It also discusses various strategies to enhance vaccine responses in older individuals, including adjustments in vaccine components, frequency, and incorporating lifestyle changes like better diet and exercise.

September 2024
National Health Commission (NHC) Key Laboratory of Enteric Pathogenic Microbiology, Jiangsu Provincial Center for Disease Control and Prevention, Nanjing, People's Republic of China.
Article Synopsis
- - The study focused on identifying phenotypes, genotypes, and vaccine coverage of *Streptococcus pneumoniae* strains from a healthy community, revealing a significant presence of this bacterium in the human nasopharynx.
- - From 500 unvaccinated individuals, 94 strains were identified, with common serotypes including 19F, 6A, and 9V; about 27.6% of strains were penicillin non-susceptible and over 80% were resistant to erythromycin and doxycycline.
- - The results highlighted various drug-resistant clone complexes, suggesting the need for pneumococcal vaccines in the national immunization schedule to curb potential infections in vulnerable populations like the elderly
β-Lactamase and Macrolide Resistance Gene Carriage in Isolates Among Children Discharged From Inpatient Care in Western Kenya: A Cross-sectional Study.
Open Forum Infect Dis
June 2024
Department of Global Health, University of Washington, Seattle, Washington, USA.
Background: Antimicrobial resistance (AMR) is a global threat to infectious disease control, particularly among recently hospitalized children. We sought to determine the prevalence and mitigating factors of resistance in enteric among children discharged from health facilities in western Kenya.
Methods: Between June 2016 and November 2019, children aged 1 to 59 months were enrolled at the point of discharge from the hospital.

Article Synopsis
- Vaccines are important because they help prevent people from getting sick and dying from infections.
- There are new types of vaccines being developed, like those for pneumococcus and meningococcus, which are especially important in places like Africa.
- Scientists are studying how different parts of vaccine design can make them work better, so they can create even more effective vaccines in the future.
Sickle Cell Disease in Early Infancy: A Case Report.
Pediatric Health Med Ther
December 2022
Enteric Disease and Vaccines Research Unit, Centre for Infectious Disease Research in Zambia (CIDRZ), Lusaka, Zambia.
Sickle cell disease (SCD) refers to a group of hereditary disorders that result in faulty hemoglobin carriage by the red blood cells. This paper discusses an atypical presentation of SCD in early infancy. Despite current literature suggesting protection by fetal hemoglobin in the first few months of life, we report a diagnosis of SCD at 2 months of age with severe symptoms requiring hospitalization.
