  • Seromolecular and histopathological study on Toxoplasma gondii infection in ruminants in Aswan, Egypt
    Ahmed Gareh, Nady Kh. Elbarbary, Ahmed Fotouh, Ahmed Maher, Yasser M. Mohamed, et al.
    BMC Veterinary Research, 2026
    Background Toxoplasma gondii is a globally distributed zoonotic parasite that affects both humans and animals, with significant implications for public health and livestock production. The current research aims to update the information on the present prevalence of T. gondii and the risk factors associated with the infection in domestic ruminants in Aswan, Egypt, from August 2024 to January 2025, using serological, histopathological, and molecular approaches. Methods The blood of 387 domestic ruminants collected during the antemortem examination from four central abattoirs in the Aswan governorate, Upper Egypt, was inspected for the occurrence of anti- T. gondii antibodies through a modified agglutination technique. Data were confirmed by a nested polymerase chain reaction that targeted T. gondii DNA ( B1 gene). Tissue specimens (heart and diaphragm) from seropositive animals were collected during postmortem examination and subjected to a histopathological and immunohistochemical approach. Results The overall occurrence of T. gondii was 29.5% (114/387), with seropositivity of 33.5% (52/155), 28.2% (22/78), 23.6% (21/89), and 29.2% (19/65) in cattle, buffalo, sheep, and goats, respectively. The studied risk factors (age, gender, breed, body condition, and location) in this study were detected to be significantly related to the presence of T. gondii infection ( p ˂ 0.05). Histopathological examination detected tissue cysts in 38 out of 114 cardiac muscles of seropositive animals and failed to detect any cysts in the diaphragm tissue, indicated by encased, circular to elongated, basophilic cysts with many bradyzoites entrenched in muscle fibers by H&E staining, while showing intense brown granule staining of lymphoblastic cells by immunohistochemistry assay. Nested PCR confirmed the presence of the B1 gene of T. gondii in blood samples of all seropositive animals (100%). Conclusions The combined use of serology, PCR, and IHC demonstrates that T. gondii is present in slaughtered ruminants in Aswan and that viable tissue cysts are present in edible tissues. These findings highlight a potential risk of zoonotic transmission through the consumption of undercooked meat and emphasize the need for monitoring and control measures to reduce the burden of foodborne toxoplasmosis in Egypt.

  • Cysticercus bovis in slaughtered cattle in upper Egypt: implications for food safety
    Nady Khairy Elbarbary, Ahmed Gareh, Maha Abdelhaseib, Ahmed Fotouh, Neveen M. Abdelmotilib, et al.
    BMC Veterinary Research, 2025
    Background Bovine cysticercosis is regarded as an essential food safety concern, causing human taeniasis, as well as a significant economic worry, as infected carcasses are condemned, frozen, and downgraded. It is caused by Cysticercus bovis (C. bovis), which is the larval stage of Taenia saginata that inhabits the small intestine of man. In the two-host life cycle, humans are the definitive hosts, and cattle are the intermediate hosts. Therefore, the current research aims to study the prevalence of C. bovis in slaughtered cattle in Aswan province, Upper Egypt, by using both macroscopic and molecular techniques. Methods A cross-sectional study on C. Bovis in slaughtered cattle was conducted from July 2023 to April 2024 at several central slaughterhouses (Edfu, Kom Ombo, Daraw, Aswan, and Abu Simbel) in Aswan province, Egypt, to ascertain the prevalence of C. bovis in 47,763 slaughtered cattle through routine daily antemortem and postmortem inspections; histopathological inspection and molecular analysis were implemented to verify the findings. Results Out of 47,763 slaughtered cattle, 1,083 (2.27%) have macroscopic C. bovis cysts. The infection rates in local and imported cattle were 1.94% (203/10438) and 2.36% (880/37325), respectively. The prevalence of C. bovis infection was found to be significantly associated with the age, sex, and body condition of slaughtered cattle (p < 0.05). In the local breed, the heart had the highest occurrence of C. bovis (64%), whereas in the imported breed, the masseter muscles were the most susceptible to infection (92.00%). The histopathological analysis demonstrated that the deteriorated cysts were situated in regions of tissue coagulative necrosis, characterized by a wide range of inflammatory infiltrates and collagen fibers, particularly eosinophils and macrophages. In addition, the muscle fibers undergo degenerative changes, which may lead to the loss of normal muscle structure. The presence of the C. bovis HDP2 gene was demonstrated by the PCR analysis of C. bovis cyst samples, which showed positive diagnostic bands at 599 bp on gel electrophoresis. Conclusions Based on the findings in this study, the slaughtered cattle meant for human consumption in Aswan, Egypt, had C. bovis lesions restricted to one or a few organs. The study revealed that the spread of infection in these valuable organs in cattle has negative implications for food safety. Recommendation We strongly support the One Health strategy for preventing zoonotic pathogens from spreading to humans and preventing economic loss in cattle production.

    MARWA E. ALY, AHMED K. DYAB, MOHSEN I. ARAFA, MADIHA DARWISH, AHMED GAREH
    Assiut Veterinary Medical Journal Egypt, 2024
    Although fish are a valuable source of animal protein for human, their production is reduced sometimes by parasitic diseases. The purpose of this study was to ascertain the frequency and importance of possible parasites that could infect freshwater fish in Sohag governorate. A total of 150 samples [100 Nile tilapia (Oreochromis niloticus) and 50 catfish (Clarias gariepinus)] were chosen at random from various farms in the Sohag Governorate for this purpose. According to the parasitological analysis of the collected fish, Clarias gariepinus had the highest infection rate 64% (32/50) compared to Oreochromis niloticus 56% (56 / 100). Quadriacanthus spp. (50%), Contracecum spp. (50%), Trichodina spp. (56%), Myxobolus spp. (55%), Cryptosporidium spp. (50%), and encysted metacercaria [microscopic (55%), and macroscopic (35%)] were the parasites found in Nile tilapia fish. In contrast, the identified parasites in catfish included microscopic encysted metacercaria (60%) and Quadriacanthus spp. (54%), Trichodina spp. (64%), Myxobolus spp. (44%), Henneguya spp. (40%), and Cryptosporidium spp. (56%). It is evident from the current study that a significant frequency of numerous zoonotic parasites were found in the fish under examination. As a result, control measures in fish farms are required to prevent the spread of these parasites, which pose a risk to public health.
  • First microscopic and molecular identification of Cryptosporidium spp. in fat sand rats (Psammomys obesus) in Egypt and their potential zoonotic implications
    Sara Abdel-Aal Mohamed, Fatma A. S. Anwar, Ahmed Gareh, Marwa M. I. Ghallab, Remigio Martínez, et al.
    Frontiers in Veterinary Science, 2024
    IntroductionRodents, thriving in human-altered environments, pose significant public health risks due to their role as reservoirs for numerous zoonotic parasites. Among these, Cryptosporidium spp. are recognized globally as leading causes of waterborne and foodborne diarrheal illnesses in humans. The specific role of fat sand rats (Psammomys obesus) in the transmission of Cryptosporidium spp. in Egypt and the genotypic characteristics of the circulating species in these animals remain poorly understood.MethodsIn this study, a total of 150 individual fat sand rat stool samples were collected from the saline marsh periurban areas of Abu-Rawash, Giza, Egypt. The samples were initially screened for the presence of Cryptosporidium spp. using light and scanning electron microscopy to characterize the parasite’s oocysts. Furthermore, molecular identification and characterization of the parasite were carried out on selected microscopy-positive samples (n = 30) using conventional polymerase chain reaction (PCR) targeting the Cryptosporidium oocyst wall protein (COWP) gene. A subset of these positive samples by PCR was subjected to sequencing, with the resulting sequences deposited in GenBank™ and analyzed through phylogenetic methods.ResultsConventional microscopy revealed that 46.7% (70/150; 95% CI: 38.7–54.6) of the analyzed stool samples contained structures consistent with Cryptosporidium oocysts. Moreover, the molecular analysis confirmed Cryptosporidium species in DNA from all 30 stool samples previously identified as heavily infected through microscopy. Notably, the phylogenetic analysis identified Cryptosporidium parvum (C. parvum) in the sequenced samples, likely originating from the rats’ native habitats. These identified species have been deposited in GenBank™ under the accession numbers OM817461 (C. parvum FSA-1), OM817462 (C. parvum FSA-2), and OM817463 (C. parvum FSA-3) and revealed closed genetic identity with those species reported from human and other animal species in the same geographic location.ConclusionOverall, this study represents the first morphological and genetic identification of C. parvum isolated from fecal samples of fat sand rats trapped from periurban areas in Egypt. These findings provide valuable insights into the potential zoonotic implications of rodents in disease transmission at the national level, offering crucial information for public health awareness campaigns and informing local authorities.

    Nasser Mohamed Abd El-kareem, Ahmed Kamal Dyab, Nada Oudah Albalawi, Abdalla Abd El Samea, Mohamed Ahmed Ali Taha, et al.
    Frontiers in Microbiology, 2024
    IntroductionTrichomoniasis remains one of the most significant sexually transmitted disease (STDs) for public health. The disease is caused by parasitic protozoa, Trichomonas vaginalis (T. vaginalis), which is often underestimated in tropical medicine. Despite its public health importance, the epidemiology and molecular characteristics of trichomoniasis in Egypt remains poorly understood, particularly in the southern part of the country (Upper Egypt). This study targeted exploring the genetic variability of T. vaginalis infections in Egyptian women living in Upper Egypt using restriction fragment length polymorphism (RFLP).Patient and techniquesThis cross-sectional study included 150 female patients, who visited the gynaecology and obstetrics outpatient clinics at Sohag General Hospital between 2019 and 2022, exhibiting symptoms of trichomoniasis. Vaginal washout samples were collected from each patient and analyzed using three diagnostic techniques: direct wet mount microscopy, culture on TYM Diamond’s medium, and PCR amplification and Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) targeting the actin gene, which was applied to all 16 samples that tested positive in culture. The PCR-RFLP results were then visualized through agarose gels electrophoresis to detect DNA fragments.ResultsOut of 150 vaginal washout samples, 12 cases (8%) tested positive for T. vaginalis trophozoites via direct wet mount microscopy, while 16 samples (10.6%) were positive in culture. Additionally, PCR-RFLP analysis of the 16 culture-positive samples revealed that 13 samples were confirmed positive using this molecular method. The amplified products were digested with the restriction enzyme Hind II, yielding three DNA fragments of 60, 213, and 827 bp, which were then detected by agarose gel electrophoresis. Digestion with RsaI produced five fragments measuring 87, 103/106, 236, and 568 bp, while MseI digestion resulted in three distinct fragments of 204, 315, and 581 bp.ConclusionThis study provides robust baseline data on the prevalence and microscopic characteristics of T. vaginalis in Upper Egypt, while also presenting, for the first time, molecular detection and genotyping and revealed that genotype E is the only prevalent genotype in the region.

    Animals, 2024
    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.

    Frontiers in Veterinary Science, 2024
    IntroductionBlood parasites pose a significant threat to livestock production in southern Egypt, yet there is a scarcity of information regarding their circulation and epidemiology in sheep in this region. This study aimed to investigate the seroprevalence of blood parasite infections in sheep in Assiut governorate, Upper Egypt.MethodsA total of 400 blood samples were collected from sheep of varying ages and genders. The preliminary screening for the presence of piroplasms, mainly Babesia and Theileria spp., via microscopic examination, followed by investigation of the potential risk factors linked with the exposure to infection. Moreover, molecular identification of both parasites on some of positive samples was performed using PCR targeting Babesia 18S rRNA and Theileria annulata Tams1 gene.ResultsThe microscopic examination revealed that among the examined sheep, there was an overall prevalence of blood parasites at 44% (176 out of 400), with Babesia spp. observed in 14% (56 out of 400) and Theileria spp. in 30% (120 out of 400). Furthermore, the infection rate was non-significantly higher in young animals (50%) compared to adults (38.5%) (P = 0.246). Male sheep exhibited a significantly higher vulnerability to both parasites' infection (63.3%) compared to females (35.7%) (P = 0.011). Interestingly, the prevalence of both blood parasites was significantly higher during the cold season (66.1%) compared to the hot season (15.9%) (P = < 0.001). The molecular analysis identified the presence of Babesia ovis and Theileria annulata among a subsample of the positive sheep's bloods films. The identified species were recorded in the GenBank™ databases and assigned specific accession numbers (OQ360720 and OQ360719 for B. ovis), and (OP991838 for T. annulata).ConclusionsTaken together, this study confirms a high prevalence of piroplasmosis and offers epidemiological and molecular insights into blood parasites in sheep from Upper Egypt, highlighting the importance of detecting these parasites in various hosts and their competent vectors (ticks).
