Pseudomonas oryzihabitans is a Pseudomonas bacterial organism rarely implicated in human infections. The bacterium has been isolated in a few reported cases of neurosurgical infections and patients with end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections. Limited information exists in developing countries, however, because of the lack of advanced microbiological tools for identification and characterization of this bacterium. This case report describes the isolation of a rare Pseudomonas bacterium in a patient presenting with sepsis and skin infection. A 1-year-old girl was presented to a hospital in the northeastern part of Ghana with a 1-week history of pustular rashes on her scalp and neck, which occasionally ruptured, along with discharge of yellowish purulent fluid. The child is of Mole-Dagbon ethnicity and hails from the northern part of Ghana. Pseudomonas oryzihabitans was identified in the patient’s blood culture using the 16S ribosomal deoxyribonucleic acid sequencing technique. The rash on the patient’s scalp and skin resolved after continuous treatment with gentamicin while her condition improved clinically. This finding suggests the potential of this bacterium to cause disease in unsuspected situations and emphasizes the need to have evidence for the use of the appropriate antibiotic in clinical settings, particularly in rural settings in Africa. It also brings to the fore the unreliability of conventional methods for identification of Pseudomonas bacteria in clinical samples and thus supports the use of 16S ribosomal deoxyribonucleic acid in making the diagnosis.
Neisseria gonorrhoeae is a Gram-negative bacterium which affects the urethra, throat, rectum and cervix of patients and often associated with sexually transmitted infections. The global epidemiology of the disease is not well characterised especially in resource constraint countries due to poor diagnostic capacity and inefficient reporting systems. Although important, little is known about the propensity of this bacterium to cause sepsis in immunocompetent individuals. A 32-year-old female presented with fever and generalised malaise to a rural hospital in Ghana. The patient had previously been diagnosed as having enteric fever from a neighbouring health facility. Blood and urine samples were collected from the patient and cultured using standard microbiological and molecular techniques. Neisseria gonorrhoeae was isolated from the blood which was resistant to penicillin, ciprofloxacin and cotrimoxazole. The patient recovered following ceftriaxone and azithromycin treatment. This case highlights the importance of N. gonorrhoeae in causing sepsis and emphasises the need for blood culture investigation in diagnosis of patients presenting with fever.
Colonization of SARS-CoV-2 with specific bacteria may either protect or increase the risk of disease severity. This study aimed to identify microbial organisms in the lower respiratory tract and their association with SARS-CoV-2 infection. This was a cross-sectional study conducted between May 2020 and August 2021 at the Tamale Public Health Laboratory in the Northern part of Ghana. RT-PCRs for SARS-CoV-2 and bacteriological cultures were performed on sputum samples collected from suspected COVID-19 patients. Biochemical identification and antimicrobial susceptibility tests were performed on the bacterial isolates. A total of 380 participants were recruited into the study. Most participants were within the 21–30 years age group (29.6%). RT-PCR testing detected SARS-CoV-2 in 118 (31.1%) patients. Headache was found to be associated with SARS-CoV-2 (p = 0.033). Sputum cultures yielded 187 (49.2%) positive bacteria growths. Klebsiella spp. (20.5%), Moraxella catarrhalis (7.9%), and Pseudomonas spp. (6.3%) were the most commonly isolated bacteria. M. catarrhalis, Serratia spp., and Stenotrophomonas maltophilia were significantly associated with SARS-CoV-2 infection. Most of the isolates were resistant to 3rd generation cephalosporins. This study has demonstrated the association between specific bacteria and SARS-CoV-2 infection. Clinicians should investigate possible bacterial co-infections in the management of COVID-19 cases.
