Summary
Cestode larvae, including coenuri and Cysticercus tenuicollis, were found in young goats in Dubai. The coenuri
Area of Science:
- Veterinary Parasitology
- Food Safety
- Helminthology
Background:
- Routine meat inspection in Dubai revealed widespread cestode larval infections in young goats.
- Two distinct types of cestode larvae were identified, affecting various tissues including liver, abdominal cavities, and muscles.
Purpose of the Study:
- To characterize the cestode larvae found in goats.
- To differentiate between Coenurus cerebralis and other related metacestodes based on morphology and location.
Main Methods:
- Examination of 300 goat carcasses aged 3-6 months.
- Morphological analysis of coenuri and Cysticercus tenuicollis metacestodes.
- Measurement of coenuri cyst volume, scolex count, and hook dimensions.
Main Results:
- Sixty-two coenuri cysts were recorded in 30 animals, with significant variation in size and scolices count.
- Coenuri structures and scolex measurements were consistent with Coenurus cerebralis.
- Metacestodes were located in the liver, abdominal cavities, under the skin, and between muscle fasciae, not in the central nervous system.
Conclusions:
- The atypical extra-neural location of coenuri suggests a potential new strain of Multiceps multiceps or a related species.
- Accurate identification of cestode larvae is crucial for veterinary diagnostics and food safety.
- Further molecular studies are recommended to confirm the species or strain identification.

01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
