Insights

Saffold virus (SAFV) was detected in 1.5% of pediatric diarrhea cases in Thailand. Four SAFV genotypes were identified, highlighting the virus

Area of Science:

  • Virology
  • Gastroenterology
  • Public Health

Background:

  • Saffold virus (SAFV), a member of the Cardiovirus genus within the Picornaviridae family, is a recently identified human pathogen.
  • Understanding the prevalence and genetic diversity of emerging viruses like SAFV is crucial for public health surveillance.

Purpose of the Study:

  • To investigate the presence and genetic characteristics of Saffold virus in fecal samples from children with diarrhea in Thailand.
  • To identify the genotypes of SAFV circulating in this pediatric population.

Main Methods:

  • RT-nested PCR and sequence analysis were employed to detect and characterize SAFV.
  • Fecal specimens were collected from 608 children experiencing diarrhea in Chiang Mai, Thailand, between January 2012 and December 2013.

Main Results:

  • SAFV was detected in 9 out of 608 (1.5%) fecal specimens.
  • Four distinct SAFV genotypes (SAFV1, SAFV2, SAFV3, and SAFV4) were identified.
  • SAFV mono-infection occurred in five cases, while co-infection with other diarrheal pathogens was observed in four cases.

Conclusions:

  • This study confirms the circulation of Saffold virus in Thailand among children with diarrhea.
  • The identification of multiple SAFV genotypes provides valuable insights into the genetic diversity of this emerging virus in the region.
  • Further research is warranted to understand the clinical significance and transmission dynamics of SAFV in pediatric populations.

Bacterial Gastroenteritis01:18

Bacterial 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...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
