Summary
Lactococcus garvieae, a zoonotic bacterium, can cause infections in humans, particularly through wound contamination. This case highlights a rare leg abrasion infection in a child, successfully treated with antibiotics.
Area of Science:
- Microbiology
- Infectious Diseases
- Zoonoses
Background:
- Lactococcus garvieae is a gram-positive bacterium found in animals and dairy, recognized as an emerging opportunistic human pathogen.
- Human infections are often linked to raw seafood consumption, with infective endocarditis being the most common presentation.
- L. garvieae can also cause other clinical manifestations, indicating its diverse pathogenic potential.
Observation:
- A case report details a 6-year-old male with infected bilateral leg abrasions after playing in a creek with livestock.
- Wound cultures identified L. garvieae as the causative agent.
- The isolated bacteria showed sensitivity to several antibiotics including ceftriaxone, levofloxacin, vancomycin, and resistance to clindamycin.
Findings:
- The patient received a ten-day course of oral cephalexin and topical gentamicin.
- Following treatment, the patient exhibited significant improvement in wound healing.
Implications:
- This case expands the known spectrum of L. garvieae infections, particularly non-seafood-related wound infections.
- It underscores the importance of considering L. garvieae in pediatric wound infections, especially in environments with potential animal or environmental exposure.
- Highlights the need for appropriate antibiotic selection based on susceptibility testing for effective management of L. garvieae infections.

01:27Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:22Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
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...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
