“…Previous works [13,20] report a prevalence rate of 4.2% and 3.63% in cattle in Egypt, which are less than the current results. However, another previous study [21] agrees with the present results and reports a prevalence rate of 7.5% in Aswan city (Upper Egypt). C. bovis is considered endemic in many parts of Africa, particularly in areas with poor sanitation and inadequate meat inspection practices.…”

Bovine cysticercosis is categorized as a serious parasitic zoonotic infestation. The infection is mainly caused by the tapeworm Taenia saginata, which infects cattle and humans. The larval stage, Cysticercus bovis (C. bovis), is found in the skeletal and cardiac muscles of infected cattle. Despite its potential public health concern, few studies have been conducted on cardiac cysticercosis in Upper Egypt. This study investigates the prevalence, epidemiology, and impact of cardiac cysticercosis in Upper Egypt, emphasizing how histopathological changes in cardiac muscle and physiological parameters might be associated with the infection. From December 2022 to October 2023, a total of 941 animals from Assiut province, Upper Egypt, were slaughtered and their cardiac muscles were examined for the presence of C. bovis. Cysts were classified as viable or degenerated through macroscopic inspection. The overall prevalence of C. bovis infected hearts made up 10.8% of the total examined. The highest prevalence rate was in the summer season followed by spring; winter had the lowest infections. The histopathological examination of infected tissues revealed immune cell infiltration around Cysticercus-infected areas. Additionally, Bax immunostaining demonstrated the apoptotic effect of cysticercosis. Regarding the measured physiological parameters, there were non-significant changes in plasma levels of total protein and albumin in cattle infected with cysticercosis compared with control animals. Moreover, there was a significant decrease in total antioxidant capacity (TAC) combined with a significant increase in lipid peroxide (Malondialdehyde) (MDA), troponin T, and lactate dehydrogenase (LDH) activity in infected animals. The present work documented a set of epidemiological and pathological findings, revealing that C. bovis is a potentially harmful parasite and can cause significant health problems in both cattle and humans.

“…The total count was calculated to be 44 and according to their viability, we classified cysts into viable, with a higher percentage (63.6%), and non-viable degenerated (36.3%). This is in accordance with results obtained by Dyab et al [27] who reported that the highest proportion of cysts (86%) were viable. viable cysts were rounded, well demarcated, with 1-2 cm diameter and grayish-white coloration.…”

N our country, imported Sudanese cattle are supposed to be an important source of high-quality protein, which is obtained from their meat and milk. Consequently, strict veterinary inspection should be applied to these animals in slaughterhouses before being subjected to human consumption. This study aims to report the unusual migration of Taenia sagniata larvae (Cysticercus bovis) to the liver of these animals and describe the pathological changes stimulated by them. In a survey started in December 2020 and ended by October 2021, 1575 livers were carefully inspected and examined, from which 172 specimens were condemned for different lesions. Prevalence of cysticercosis was 1% (16/1575) among the totally examined livers. However, out of the rejected specimens, cysticercosis occurred at a percentage of 9.3% (16\172). 5 livers showed a single cyst, while 11 showed multiple. The total cyst count was 44, of which 28/44 (63.6%) were viable with thin transparent walls and discharging of spotted scolex on incision. However, 16/44 (36.3%) cysts were degenerated and appeared firm, pale yellowish, with firm consistency. The morphological appearance of the liver varied from normal structure and consistency to swollen with rounded borders. Histopathological analysis showed a fully developed bladder-like cyst with its invaginated scolex in liver tissues resulting in necrotic changes in hepatocytes, fibrosis and inflammatory infiltrate. Due to the significant risk of Cysticercus bovis to human health, meat inspection must be carefully considered.

“…Besides, [6] who found that 7.3% of the inspected cattle in North Egypt had cysticercosis lesions during postmortem inspection. Moreover, similar findings were observed by [5] in Egypt where the infection rate was (7.5%). Lower infection rate than our findings were recorded by [42] in Nigeria 3%, and [43] 3.6% in Ethiopia [8] conducted a cross-sectional study on the disease, in slaughtered cattle at municipal abattoirs in Ethiopia and recorded very high prevalence 27.3%.…”

The aim of the present study was to determine the prevalence of bovine cysticercosis in both cattle and buffloas, in Egypt and to assess the cysticidal efficacy of Balanites aegyptiaca fruits (B. aegyptiaca) and Moringa oleifera seeds (M. oleifera) extracts in experimentally infected mice. The study detected the level of tumor necrosis factor (TNF-α) to monitor the immune and inflammatory responses of experimentally infected mice. Through meat inspection, a total number of 2125 male bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were examined under the authority of Albsatine and Alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from March 2022 to April 2023. The overall prevalence of the disease among bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and M. oleifera extracts showed cysticidal activity in experimentally infected mice. A decrease in the numbers of cysticerci was found in all treated mice groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group; higher than that was recorded in both M. oleifera (72.23%
