Abstract

Insights

Fungal microbes, particularly Candida species, are common in post-laparoscopic sleeve gastrectomy leaks. Empirical antimicrobial therapy for these leaks should also target common bacteria like Klebsiella, Streptococcus, and Pseudomonas.

Area of Science:

  • Gastroenterology
  • Surgical Infections
  • Microbiology

Background:

  • Post-laparoscopic sleeve gastrectomy (LSG) leaks can cause severe complications and mortality.
  • Understanding the microbial patterns in these leaks is crucial for effective empirical antimicrobial therapy.

Purpose of the Study:

  • To establish the microbial pattern of intra-abdominal leaks following LSG.
  • To inform empirical antimicrobial treatment strategies for post-LSG leaks.

Main Methods:

  • Review of microbial cultures from 31 patients with post-LSG leaks managed at King Khalid University Hospital (May 2011-April 2016).
  • Computed tomography (CT)-guided aspiration and drainage for leak collection.
  • Analysis of culture results for fungal and bacterial organisms.

Main Results:

  • 90.3% of patients had positive culture results.
  • Candida species were the most common isolates (61.2%), with Candida albicans being the most frequent (68.4% of Candida).
  • Bacterial cultures were positive in 58% of patients, with Klebsiella pneumoniae (44.4%), Streptococcus, and Pseudomonas species being the most frequent.

Conclusions:

  • Fungal microbes are prevalent in post-LSG leak collections and should be considered in initial empirical therapy.
  • Empirical antibiotic selection for post-LSG leaks should include coverage for Klebsiella, Streptococcus, and Pseudomonas pending definitive culture results.

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

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...

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Fungal Phylum Basidiomycota

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Bacterial Transformation

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...
