In human the disease occurs by the ingestion of parasite eggs and can create in any organ especially liver and lungs. Current therapeutic methods have some limitations. Therefore, effect of pulsed electric fields (PEF) as a non-invasive method was utilized on daughter cysts as an important part of hydatid cyst. Daughter cysts was extracted from sheep liver hydatid cyst, divided into three groups. The first group was exposed to PEF at intensities of 70V/cm, 150 V/cm and 1300V/cm. The second group was treated with albendazole (100 μg/ml). The third group, was exposed with different intensities of PEF (as above) following incubation of daughter cysts with albendazole (100 μg/ml). Structural changes in the daughter cysts were analyzed using a stereomicroscope. The laminated layer remained undamaged in all three groups. In the first group (PEF), some degree of opacity and detachment of germinal layer was observed especially in higher pulse intensity (1300 V/cm). Albendazole treatment (second group) induced significant opacity. In the combined PEF and albendazole (third group), although germinal layer detachment was occurred in addition to opacity but the level of detachment was not similar to those that observed in the first group. The destructive effect of PEF on the germinal layer of daughter cysts can be considered as a promising result in the treatment of CE.</p>","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"71 ","pages":"63-69"},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a threat to the buffalo population in Pakistan due to high mortality rates and economic losses. Extensive mixed farming in Pakistan poses threats due to mixed infections and increased mortality rates. The current case report describes the mixed infection and characterization of Theileria lestoquardi with Theileria annulata in a buffalo raised in a mixed farming setup, in Pakistan. A 6.5-year-old female buffalo presented at the Outdoor Hospital exhibiting swollen sub-scapular lymph nodes, pale mucous membranes, a high fever (41.5°C), dullness, depression, shortness of breath, and a decrease in milk production. Investigation through microscopy, hematology, and PCR confirmed that the buffalo was suffering from theileriosis. A Giemsa-stained thin blood smear showed piroplasms indicating theileriosis. Hematological analysis of the blood revealed lower values for hemoglobin and red blood cells (RBCs), while higher counts of lymphocytes, neutrophils, and monocytes were observed during the infection. The PCR performed on the blood sample was positive for Theileria spp. using RLB universal primers and T. annulata-specific primers. The sequence revealed similarity with T. lestoquardi reported in Pakistan, Iran, Tunisia, and India. The buffalo was treated with Bupralex® and Oxtra LA® at a dosage of 1ml/20kg of body weight I/M, respectively, along with supportive treatment. Despite these interventions, the animal died probably due to damage to cardiac muscles. This study reports the first case of T. annulata mixed infection with T. lestoquardi in a buffalo in Punjab, Pakistan.

AI-driven solutions have the potential to improve malaria prevention and eradication efforts with sustained innovation and investment, ultimately enhancing global health security. AI is transforming the treatment of malaria by facilitating personalised medicine, speeding up drug discovery, and enhancing diagnostics. AI is improving treatment approaches and tackling the problems caused by drug-resistant malaria parasites through machine learning, deep learning, and in silico drug repurposing. Achieving long-term malaria eradication targets will require sustained investment in AI-driven malaria research. In epidemiological tracking, artificial intelligence (AI) has also become a potent instrument.
