Abstract

Insights

Trueperella pyogenes, formerly Arcanobacterium pyogenes, causes diverse pyogenic infections in domestic animals. Mastitis and abscesses are most common, and antimicrobial susceptibility testing is crucial for effective treatment.

Area of Science:

  • Veterinary Microbiology
  • Animal Infectious Diseases

Background:

  • Arcanobacterium pyogenes has been renamed Trueperella pyogenes.
  • This opportunistic bacterium is associated with various pyogenic infections in domestic animals.
  • Limited case series studies exist on T. pyogenes infections.

Purpose of the Study:

  • To retrospectively analyze epidemiological and clinical features of T. pyogenes infections in domestic animals.
  • To determine the in vitro antimicrobial susceptibility patterns of T. pyogenes isolates.
  • To evaluate 144 cases of T. pyogenes infections from 2002 to 2012.

Main Methods:

  • Isolation of T. pyogenes from clinical specimens of various domestic animals including cattle, goats, sheep, pigs, horses, dogs, and buffaloes.
  • Retrospective analysis of epidemiological and clinical data.
  • Antimicrobial susceptibility testing using various drugs.
  • Statistical analysis using Chi-square or Fisher's exact tests.

Main Results:

  • Mastitis (45.1%), abscesses (18.0%), pneumonia (11.1%), and lymphadenitis (9.0%) were the most frequent clinical presentations.
  • No significant association was found between T. pyogenes infections and host age, gender, or season.
  • High efficacy was observed for florfenicol, cefoperazone, cephalexin, and ceftiofur, while resistance was noted for trimethoprim-sulfamethoxazole and norfloxacin.

Conclusions:

  • Trueperella pyogenes exhibits diverse clinical manifestations and opportunistic behavior in domestic animals.
  • Mastitis, abscesses, pneumonia, and lymphadenitis are predominant infections.
  • Antimicrobial susceptibility testing is essential for guiding appropriate therapeutic strategies and improving treatment outcomes.

Bacterial 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...

Bacterial Phylum Tenericutes01:24

Bacterial Phylum Tenericutes

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Atypical Pneumonia01:14

Atypical 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...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Clinical Significance of Antibiotic Resistance01:25

Clinical 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...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
