ABSTRACT

Chryseobacterium demonstrates a diverse environmental presence and a significant pathogenic potential across various ecosystems. This clinical case showcases a rare instance of bacterial infection in a 75-year-old male with untreated diabetes and recurrent urinary tract infections (UTIs). The patient presented symptoms of abdominal pain, burning urination, fever, and an elevated eosinophil count. A subsequent urine culture identified a Chryseobacterium-related bacterium as the causative agent, exhibiting sensitivity to piperacillin/tazobactam, trimethoprim/sulfamethoxazole, and nitrofurantoin, which led to successful treatment using oral nitrofurantoin. Analysis of the 16S rRNA gene sequence of APV-1T revealed a close relationship of 98.2% similarity to Chryseobacterium gambrini strain 5-1St1aT (AM232810). Furthermore, comparative genome analysis, incorporating Average Nucleotide Identity (ANI), Digital DNA-DNA Hybridization (dDDH) values, and comprehensive phylogenetic assessments utilizing 16S rRNA gene sequences, core genes, and amino acid sequences of core proteins, highlighted the unique phylogenetic positioning of APV-1T within the Chryseobacterium genus. Distinct carbon utilization and assimilation patterns, along with major fatty acid content, set APV-1T apart from C. gambrini strain 5-1St1aT. These findings, encompassing phenotypic, genotypic, and chemotaxonomic characteristics, strongly support the proposal of a novel species named Chryseobacterium urinae sp. nov., with APV-1T designated as the type strain (= MCC 50690 = JCM 36476). Despite its successful treatment, the strain displayed resistance to multiple antibiotics. Genomic analysis further unveiled core-conserved genes, strain-specific clusters, and genes associated with antibiotic resistance and virulence. This report underscores the vital importance of elucidating susceptibility patterns of rare pathogens like Chryseobacterium, particularly in immunocompromised individuals. It advocates for further analyses to understand the functional significance of identified genes and their implications in treatment and pathogenesis.

ABSTRACT

Hydatid disease is a parasitic infestation by larval form of Echinococcus granulosus. Isolated renal involvement is extremely rare. There are no specific signs and symptoms of renal hydatidosis. However it may present as palpable mass, flank pain, hematuria, malaise, fever, and hydatiduria or as a complication of it such as infection, abscess, hemorrhage, necrosis and pelviureteric junction obstruction, renal failure etc. Except hydatiduria, none are pathognomonic for renal hydatidosis. There is no literature on renal hydatidosis presenting as renal mass we report 2 cases of isolated renal hydatidosis, which mimicked a renal mass on imaging study.

ABSTRACT

BACKGROUND: The pigmented or melanotic variant of choroid plexus carcinoma is very rarely encountered. CASE REPORT: We report herein a case of melanotic or pigmented choroid plexus carcinoma in the posterior fossa of an 11-year-old female. CONCLUSIONS: A histopathological study supported by immunohistochemistry helped the authors to diagnose this rare entity. How to differentiate this tumor from pigmented papillary medulloblastoma, cerebellar papillary ependymoma, and metastatic malignant melanoma is discussed.

ABSTRACT

Philadelphia chromosome (Ph(1))-positive Chronic Myelogenous Leukemia (CML) in a child below the age of 3 years is extremely rare. We have reported such a case in a 3 year old male child. Peripheral blood smear revealed features of CML and karyotypic study showed (Ph(1)) positivity. Biologic behaviour and prognosis are similar to that of adult-type of CML.

ABSTRACT

Aspergillosis of central nervous system is an uncommon infection mainly occurring in immunocompromised patient. It may be present in several forms: abscess, meningitis, mycotic aneurysm, infarction and in tumoral form. Here we report a case of cerebral aspergillosis presenting as bilateral frontal lobe abscess without evidence of any underlying systemic disorder or extracranial disease.
