(1) Intestinal microbial parasites are major contributors to the global burden of gastrointestinal disease. Such infections are mainly caused by Cryptosporidium, Giardia duodenalis, and Entamoeba histolytica. These parasites are transmitted either directly or indirectly through oral–fecal routes. Previous reports suggested that camels could play a role in the zoonotic transmission of various clinically and veterinary important intestinal parasites, however, limited data are available on intestinal infections of camels, particularly on a molecular level. We aimed to explore the occurrence of these three parasites in camels (Camelus dromedarius) in Algeria. (2) A total of 68 samples—63 stool samples from camels and five from the environment—were collected from two desert regions in Algeria and analyzed using PCR and qPCR methods. (3) Overall, 7% of the camels tested positive for zoonotic subtypes of Cryptosporidium spp., while 16% of the camels tested positive for G. duodenalis. Two environmental samples also tested positive for G. duodenalis. None of the samples were positive for Entamoeba histolytica. (4) Our results provide one of the first molecular-based identification of these gut parasites in dromedary camels in Algeria. The presence of G. duodenalis in the host and the environment unveils, in part, the circulation route of this parasite. Our results will spearhead further investigations into the prevalence and epidemiology of gut parasites in hoofed animals and raise questions concerning their role in health and disease in the area.

Thirteen female camels were used in this study to investigate the changes in some haematological parameters during the different stages of lactation including early lactation, mid-lactation and the last stage of lactation. A significant decrease (P<0.001) in mid and late lactation, compared to early lactation was recorded for the following parameters: number of white blood cells, number of lymphocytes, number of monocytes, number of granulocytes, per cent ratio of lymphocytes and mean corpuscular volume. While, the levels of per cent ratio of monocytes, per cent ratio of granulocytes, red blood cells and haematocrit were low in early lactation then showed a significant raise in mid and late lactation (P<0.001). Moreover, The levels of mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were high during early lactation, then significantly decreased (P 0.05). The current study gives baseline data about the value change of the main haematological parameters during lactation in female camels in the Algerian desert and these results could be used as a database for the diagnosis of different disorders and also for upcoming research in camels.

This study provides the first comprehensive nanoscale and functional evaluation of camel myofibrillar proteins subjected to long‐term frozen storage. A combination of atomic force microscopy (AFM), biochemical assays, and electrophoresis was employed to investigate structural integrity, gelation capacity, and protein stability in Biceps femoris and Longissimus lumborum muscles, analyzed in both fresh and preserved states (−20°C for 1 year), including post‐heating conditions simulating gel formation. AFM revealed significant topographical alterations in preserved samples, particularly in L. lumborum , including increased surface roughness, disrupted fibrillar architecture, and enlarged cross‐sectional dimensions. These nanoscale changes were accompanied by increased solubility and surface hydrophobicity, alongside significantly reduced sulfhydryl group availability, which results in oxidation, aggregation, and compromised gel matrix stability. In contrast, fresh samples retained a compact, homogeneous network with smoother surfaces, reflecting superior molecular organization and functional integrity. SDS‐PAGE confirmed progressive degradation of key myofibrillar proteins—MHC, actin, α‐actinin, troponin T, and MLC, with preserved L. lumborum exhibiting additional low‐molecular‐weight bands, indicative of extensive proteolysis. These structural disruptions correlated with reduced gel cohesiveness and potentially diminished water‐holding capacity, key quality attributes in muscle‐based food systems. Overall, this study demonstrates that prolonged freezing induces pronounced nano‐structural and functional destabilization of myofibrillar proteins, with responses that differ according to muscle‐specific composition.

Foot-and-mouth disease (FMD), bluetongue (BT), and Peste des Petits Ruminants (PPR) are major emerging and re-emerging viral infections affecting ruminants. These diseases can threaten livestock health, food security, and economic stability in low- and middle-income countries, including Algeria. However, their dynamics remain mostly unknown, limiting the implementation of effective preventive and control measures. We analyzed outbreak data reported by Algerian veterinary authorities and the WAHIS database from 2014 to 2022 for FMD; from 2006 to 2020 for BT; and from 2011 to 2022 for PPR to investigate their spatiotemporal patterns and environmental drivers. Over these periods, Algeria reported 1142 FMD outbreaks (10,409 cases; 0.16/1000 incidence), 167 BT outbreaks (602 cases; 0.018/1000), and 222 PPR outbreaks (3597 cases; 0.096/1000). Small ruminants were the most affected across all diseases, although cattle bore the highest burden of FMD. BT primarily impacted sheep, and PPR showed a higher incidence in goats. Disease peaks occurred in 2014 for FMD, 2008 for BT, and 2019 for PPR. Spatial analyses revealed distinct ecological hotspots: sub-humid and semi-arid zones for FMD and BT, and semi-arid/Saharan regions for PPR. These patterns may be influenced by species susceptibility, animal movement, trade, and climatic factors such as temperature and rainfall. The absence of consistent temporal trends and the persistence of outbreaks suggest multiple drivers, including insufficient vaccination coverage, under-reporting, viral evolution, and environmental persistence. Our findings underscore the importance of targeted species- and region-specific control strategies, including improved surveillance, cross-border coordination, and climate-informed risk mapping. Strengthening One Health frameworks will be essential to mitigate the re-emergence and spread of these diseases.
