Objective: To investigate current epidemiological status of Taenia solium infection and cysticercosis in Shandong Province.
Methods: By house to house interview in the field, fecal examination and serological tests, the prevalence data of taeniasis and cysticercosis in human and pig population, and epidemiological factors in relation to the diseases were carried out.
Results: The prevalence of Taenia infection and cysticercosis in human population were 0.048% and 0.057% respectively. The sero-positive rate of the specific IgG4 of anti-Cysticercus was 1.91%. The prevalence differed among occupations and from region to region, but there was no significant difference between men and women, city and suburb. Unhealthy eating and unhygienic habits commonly practised among residents, 92.3% of the families have "latrines connected to pigsties". The surrounding sanitation and the disposal of fecal material were poor. The detection rate of porcine cysticercosis was 0.06%, and the positive rate of anti-Cysticercus antibody in pigs was 1.99%.
Conclusion: The prevalence of taeniasis and cysticercosis is decreasing. However, the endemic area is expanding and the epidemiological factors are still existing. Continued effort is therefore needed for sustain the control programme.

Taenia solium is a parasite and is endemic in the developing countries due to various unhygienic faecal practices. The disseminated form is commoner with the brain being the most common site of affliction. This report is of a young female patient with complaints of an insidious and progressive swelling of the right forearm.

Background: Cysticercosis, a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium, predominantly affects cerebral and ocular tissues. The subcutaneous manifestation of this disease is a relatively uncommon clinical occurrence. Previously very few or no cases of cysticercosis presenting as subcutaneous solitary painful swelling have been reported in the literature.

Meat inspection is the routine method used to identify cattle infected with Taenia saginata; however, the sensitivity of this method is low. We investigated the prevalence of T. saginata infection in cattle slaughtered in low throughput abattoirs (LTs) in Gauteng province, South Africa, based on meat inspection and serology.

Article Synopsis
- - Cysticercosis is a parasitic infection caused by the pork tapeworm, often linked to chronic headaches and epilepsy in areas like Latin America and Asia, especially when it affects the central nervous system (neurocysticercosis).
- - A serosurvey in Starr County, Texas, identified a 7.4% prevalence of cysticercosis among Mexican-American adults, with brain imaging revealing neurocysticercosis lesions in 2 of the 45 seropositive individuals.
- - Factors such as being female, working in healthcare or social services, and having an indoor job were significantly associated with a higher likelihood of being seropositive, indicating a need for more research on
