An outbreak of foot-and-mouth disease (FMD) in Egypt affected approximately 40,000 cattle and water buffaloes and killed more than 4,600 animals during February-March 2012. To investigate the etiology of the 2012 outbreak, specimens were collected from six governorates and analyzed using universal primers to amplify the 5' untranslated region (UTR) by reverse-transcription polymerase chain reaction. Only FMDV-SAT2 was detected, with an overall detection rate of 80.3 %. Complete VP1- and leader-proteinase-coding sequences, obtained from three isolates from three different governorates, were compared with previously reported sequences. Phylogenetic analysis of these sequences indicated that the circulating viruses were homogeneous and were closely related to topotype VII. Importantly, the newly emerged viruses were genetically closely related to strains isolated from Saudi Arabia, Sudan, Eritrea and Cameroon between 2000 and 2010, suggesting the dominant nature of this virus and underscoring the need for worldwide intensive surveillance to minimize its devastating consequences.

Background: Gastrointestinal parasitic diseases remain an obstacle in goat industry in Egypt and worldwide. This study was conducted for assessing the prevalence of the gastrointestinal parasitic infections among goats in Giza Governorate, Egypt. To fulfill this study, examination of 225 fecal samples of live animals kept by small holders was done, as well as postmortem investigation of 135 random slaughtered goats' gastrointestinal tracts was achieved during the period from March to May 2018. Results: The examination of fecal samples revealed that overall prevalence of gastrointestinal parasitic infections among goats was 89.33%. The respective prevalence of kids, yearling, and adults were 89.16%, 98.44%, and 82.05%. The common parasitic infections prevalent were Coccidia spp. (76.89%), Entamoeba spp. (26.22%), Moniezia spp. (18.22%), Strongyle group (12.88%), Trichuris ovis (5.33%), Strongyloides papillosus (3.55%), Balantidium coli (2.66%), and Fasciola spp. (0.89%), successively. Mixed infection was recorded as 61.77% in the examined goats. The present study showed that the prevalence of infection by Coccidia spp., Moniezia spp., and Strongyle group was the highest in the yearling age group. In contrary, the infection prevalence of Entamoeba spp. was significantly high in the adult age group. No significant difference was found relying on the sex of the goats. The post-slaughtering finding showed that Haemonchus contortus was the most prevalent nematode followed by Trichuris ovis and Trichostrongylus axei. Remarkable infection percentage of Taenia hydatigena metacestode (Cysticercus tenuicolli) is recorded in the omentum of the intestine (31.85%). Conclusions: The present study provides basic data about the most prevalent GIP diseases among goats in Giza Governorate, Egypt, which required for evaluation of the followed management and control measures. This work elicited the risk of transmission of some zoonotic diseases via goats. Fecal examination and postmortem finding-based surveys remain of choice particularly in the deprived investigating areas.

Aim: The effect of some variables on hydatidosis in animals slaughtered at Cairo and Giza abattoirs was investigated and the influence on serum biochemical parameters, antioxidant enzymes, and histopathological lesions caused by these parasites as a consequence was estimated. Materials and Methods: The effect of some variables on hydatidosis in 397 sheep, 401 cattle, 435 buffaloes, and 341 camels slaughtered at Cairo and Giza abattoirs was investigated, and the influence on serum biochemical parameters, antioxidant activity and histopathological lesions caused by these parasites as a consequence was estimated. Results: The results revealed that 39 sheep (9.8%), 74 cattle (18.4%), 95 buffaloes (21.8%), and 79 camels (23.25%) were infected. Concerning age variations, 165 young and 232 adult sheep, 215 young and 186 adult cattle, 194 young and 241 adult buffaloes, and 112 young and 229 adult camels were examined. The prevalence of hydatidosis was higher in adult sheep, cattle, and camel; 32 (13.8%), 49 (26.3%), and 56 (24.5%) than the younger ones 7 (4.2%), 25 (11.6%), and 23 (20.5%), respectively. Two hundred and eighty-eight sheep, 171 cattle were examined during winter. However, 109 sheep, 230 cattle were examined during summer. Hydatidosis infection in sheep and cattle was higher in winter 26 (9.01%) and 47 (27.5%) than in summer 13 (11.9%) and 27 (11.7%), respectively. Out of 133 sheep and 128 camels slaughtered in El-Basatin abattoirs, 36 (15.3) and 38 (29.7%) showed higher prevalence than that from El-Warak and El-Moneib abattoirs. Comparing with the non-infected groups, alkaline phosphatase activity decreased in hydatid-infected animals, while cholesterol and liver enzymes activities increased. Total lipid and triglyceride levels decreased in infected camels. Glutathione peroxidase, superoxide dismutase, and catalase decreased in hydatid-infected animals. Conclusion: The disturbance in the biochemical parameters, liver enzymes, and the antioxidant activities was consistent with the pathological findings that indicated the risk of hydatidosis infection. Finally, this study clarified the variabilities of hydatidosis in Cairo and Giza abattoirs as a starting point for future studies in different regions in Egypt.

Background and Aim: Lumpy skin disease (LSD), an infectious disease of cattle, is characterized by raised nodules on the skin. Although the morbidity rate of LSD is low, it has a considerable fatality rate. Despite the annual mass vaccination of livestock with sheep pox vaccine (Veterinary Serum and Vaccine Research Institute, Egypt) enforced by Egyptian authorities, the LSD virus (LSDV) continues to circulate almost every summer. The present study aimed to discover the cause of cows naturally infected with LSDV circulating in Upper Egypt during the summer of 2018 using polymerase chain reaction (PCR) assay and to analyze their phylogenetics against reference genome sequences. Materials and Methods: We cultured LSDV in specific pathogen-free embryonated chicken eggs (SPF-ECE) and used conventional PCR to identify fusion and P32 genes, previously deposited in GenBank (MN694826, MN694827, and MN954664). Sequencing and phylogenetic analyses were performed on these two highly conserved viral genes. Results: LSDV infection of SPF-ECE resulted in characteristic white pock lesions. PCR products were identified on 1.5% agarose gel after electrophoresis at the expected positions for the fusion and P32 genes at 472 and 587 bp, respectively. Conclusion: The present study revealed that the two viral genes were identified from the Beni Suef and Sohag Governorates in all clinical cases and confirmed the circulation of LSDV in this outbreak. After sequencing, these genes were identical to those of the LSDV that had been identified and recorded in GenBank for the past 3 years.
