Intestinal parasites in Hong Kong
1Institute of Pathology, Sai Ying Pun Polyclinic, Hong Kong.
Summary
Intestinal parasite infections in Hong Kong have shifted, with declines in Ascaris linked to urbanization and slower decreases in clonorchiasis due to dietary habits. Patterns vary across Southeast Asia.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Intestinal parasitic infections pose a significant public health challenge globally.
- Understanding temporal trends in parasite prevalence is crucial for effective control strategies.
Purpose of the Study:
- To analyze changes in the epidemiology of intestinal parasites in Hong Kong over a 12-year period.
- To compare current infestation patterns with historical data and regional trends.
Main Methods:
- Retrospective analysis of laboratory records for 8590 stool samples examined between January and June 1992.
- Comparison of infestation patterns, including age of acquisition and peak occurrence, with data from 12 years prior.
Main Results:
- Significant decline in Ascaris infections, correlated with Hong Kong's urbanization.
- Slower decline in clonorchiasis, potentially linked to persistent local culinary practices.
- Observed similar declines among Vietnamese migrants and varying patterns across Southeast Asia.
Conclusions:
- Urbanization and socioeconomic factors significantly influence intestinal parasite prevalence.
- Dietary habits play a role in the persistence of certain parasitic infections.
- Epidemiological patterns of intestinal parasites exhibit considerable regional variation.

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Anatomy of the Intestines
86.9K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Histology of the Large Intestine
2.9K
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
