Summary
A novel streptococcal species, Streptococcus plurextorum sp. nov., was identified from pig clinical samples. Molecular and biochemical analyses confirmed it as a distinct species within the Streptococcus genus.
Area of Science:
- Microbiology
- Bacteriology
- Genomics
Background:
- An unknown Gram-positive, catalase-negative coccus was isolated from clinical samples in pigs.
- Initial tests suggested the organism belonged to the Streptococcus genus.
Purpose of the Study:
- To identify and characterize the novel bacterial species.
- To determine its phylogenetic relationship to known Streptococcus species.
Main Methods:
- Biochemical and cellular morphological testing
- 16S rRNA, rpoB, and sodA gene sequencing
- DNA-DNA hybridization
Main Results:
- The organism was identified as a distinct species within the Streptococcus genus.
- Phylogenetic analysis showed closest relation to Streptococcus suis (97.2% 16S rRNA similarity).
- DNA-DNA hybridization revealed 36.6% reassociation with S. suis NCTC 10234(T).
Conclusions:
- The unidentified organism represents a novel species, Streptococcus plurextorum sp. nov.
- Phenotypic and phylogenetic data support its classification as a new species.
- The type strain is 1956-02(T) (=CECT 7308(T)=CCUG 52972(T)).

01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
01:30Bacterial Phylum Spirochaetes
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
