Abstract
The larvae of Cephalopina titillator cause nasopharyngeal myiasis in camels, which parasitize the living tissues of the nasal and paranasal sinuses, pharynx, and larynx. C. titillator infestation adversely affects camel health, meat, and milk production, and can even cause death. In our study, to improve the immunodiagnosis of camel nasal myiasis, a sensitive and specific enzyme-linked immunosorbent assay (ELISA) was developed and evaluated using the Concanavalin-A (Con-A) affinity purification for the C. titillator-N-acetylglucosamine (Ct-GlucNAc) glycoprotein fraction from third larval instars as an antigen for detecting C. titillator antibodies. Crude antigens were prepared from larval instars of C. titillator and evaluated by indirect ELISA. The third C. titillator larval antigen (L3Ct) had the highest protein content (P < 0.001) and the best diagnostic value; chi-square = 235 (P < 0.001). Four glycoprotein fractions were purified separately from the L3Ct antigen by Con-A purification and evaluated. The Ct-GlucNAc glycoprotein fraction was the fraction of choice with the highest diagnostic accuracy (P < 0.05). Using Ct-GlucNAc as a coating antigen, indirect ELISA showed a 99.3% sensitivity for positive results in camel myiasis samples and 100% specificity for negative results in healthy camel samples. The diagnostic accuracy was 99.7%, and no cross reactivity was detected for other parasitic diseases. The indirect ELISA results were confirmed by the western immunoblotting which was characterized by comparing sera from naturally infested dromedary camels with C. titillator, sera from healthy camels and sera from camels with other parasitic infections (Echinococcus granulosus, Fasciola gigantica, Hard ticks; Hyalomma dromedarii, Trichostronglid sp., Eimeria spp., and Cryptosporidium sp.). Immunoreactive antigenic bands of 63, 50, 30 and 18 kDa were predominantly detected in sera from camels with nasopharyngeal myiasis and didn't react with healthy and camel's sera from other parasitic infections. However, seven immunoreactive bands appeared at 120, 70, 63, 48, 35, 29, and 19 kDa in the crude L3Ct antigen. In addition, a positive rate of C. titillator immunodiagnosis was detected by indirect ELISA (48.6%, chi-square = 483, P < 0.001), which was significantly greater than that of postmortem diagnosis (31%). In conclusion, the current study introduces a new diagnostic immunoaffinity glycoprotein fraction of C. titillator 3rd larval instar-based ELISA as a highly accurate, simple and fast method to detect specific antibodies of nasal myiasis in camels.

Molecular characterization of Cryptosporidium spp. in Bactrian camels ( Camelus bactrianus) from Yili Kazak Autonomous Prefecture of Xinjiang, China. Front Vet Sci 2024; 11:1411377. [PMID: 38915888 PMCID: PMC11195013 DOI: 10.3389/fvets.2024.1411377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Accepted: 05/02/2024] [Indexed: 06/26/2024] Open
Abstract
Introduction Cryptosporidium spp. is a significant zoonotic parasite. The prevalence and infection characteristics of Cryptosporidium spp. in Bactrian camels in Yili Kazak Autonomous Prefecture have yet to be fully understood. Thus, the molecular epidemiology of cryptosporidiosis in camels was investigated in this region. Methods A total of 1,455 fecal samples were collected from 6 counties in three regions (Altay, Tacheng, and Yili) in Yili Prefecture. Nested PCR targeting the small subunit ribosomal RNA (ssu rRNA) gene was used to identify the species or genotypes of Cryptosporidium infection in camels. For C. parvum positive samples, the subtypes were identified using the 60-kDa glycoprotein (gp60) gene. Results and discussion The overall infection rate was 8.7% (126/1,455), ranging from 5.6% to 11.7% in different regions, and 4.2% to 15.8% in different counties. A significant difference was observed amongst the counties (p < 0.001). Three species were detected, namely C. andersoni (65.1%, 82/126), C. parvum (34.1%, 43/126), and C. occultus (0.8%, 1/126). Three C. parvum subtypes, If-like-A15G2 (n = 29), IIdA15G1 (n = 4), and IIdA19G1(n = 1) were detected, with If-like-A15G2 being the most prevalent subtype. Camels aged 3-12 months exhibited the highest infection rate (11.4%, 44/387), with no significant difference among age groups (p > 0.05). C. parvum was predominant in camels under 3 months, while C. andersoni prevailed in camels over 3 months. There was an extremely significant difference observed among seasons (p < 0.001), summer had the highest infection rates (16.9%, 61/360). This study collected nearly 1,500 samples and, for the first time, investigated Cryptosporidium spp. infection in camels based on different age groups and seasons. All three Cryptosporidiumspecies identified were zoonotic, posing a potential threat to human health and requiring close attention.

Abstract
The camel has played a role in human civilization since its inception and holds significant importance in the customs and agricultural practices of various nations. This study examined the prevalence of internal parasitic infestations in camels within the Al-Diwaniyah and Al-Najaf provinces of Iraq from December 2021 to September 2022. A total of 200 fecal samples were randomly collected from farm camels, revealing that these animals were affected by one or more types of intestinal parasites. Nematodes exhibited the highest prevalence at 56 %, followed by Protozoa at 28.5 %, Cestodes at 14.5 %, and Trematodes at 1 %. Among these parasites, Trichostrongylus spp. had the highest percentage at 33 %, followed by Moneizia benedeni (12.5 %), Fasciola hepatica (10.5 %), Strongyloides spp. (8 %), Giardia spp. (7 %), Nematodirus spp. (6 %), and Eimeria spp. (6 %). Furthermore, mixed-species or single-species infections in camels were observed, including Anoplcephala perfoliata (4 %), Haemonchus spp. (3.5 %), Dictyocaulus spp. (3 %), Trichuris trichura (2.5 %), Entamoeba spp. (2 %), and Balantidium coli (1 %). Additionally, nested PCR was employed to identify Trichostrongylus spp., with 45.4 % of camels testing positive for this particular parasite.

Abstract
There are limited reports of mandibular infections and tooth root abscesses in camels (Old World Camelids). This is in contrast to multiple reports and case series detailing diagnosis, management, and therapy of similar infections in New World Camelids such as llamas and alpacas. The purpose of this case series is to present three cases of camels in North America with these infections and to detail the diagnostics, therapeutic interventions, management, and follow-up of these cases. Radiography was utilized in all three cases, as was sedation and/or anesthesia. Similar to llamas, florfenicol was used for antimicrobial therapy and flunixin meglumine was utilized as a nonsteroidal anti-inflammatory. Some degree of lavage was required for the management of each case. Clinicians should be aware of the potential need for sedation, diagnostic imaging, culture, and extended therapies for the treatment of mandibular and tooth root infections in camels as comparatively described for llamas and alpacas.

Abstract
The burden of gastrointestinal parasites in zoo animals has serious implications for their welfare and the health of veterinarians and visitors. Zhuyuwan Zoo is located in the eastern suburb of Yangzhou city in eastern China, in which over 40 species of zoo animals are kept. In order to understand the infection status of GI parasites in Zhuyuwan Zoo, a total of 104 fresh fecal samples collected randomly from birds (n = 19), primates (n = 19), and non-primate mammals (n = 66) were analyzed using the saturated saline flotation technique and nylon sifter elutriation and sieving method for eggs/oocysts, respectively. Two Ascaris species were molecularly characterized. The results showed that the overall prevalence of parasitic infection was 42.3% (44/104). The parasitic infection rate in birds, primates, and non-primate mammals were 26.3% (5/19), 31.6% (6/19), and 50.0% (33/66), respectively. A total of 11 species of parasites were identified, namely, Trichostrongylidae, Capillaria sp., Trichuris spp., Strongyloides spp., Amidostomum sp., Toxascaris leonina, Baylisascaris transfuga, Parascaris equorum, Paramphistomum spp., Fasciola spp., and Eimeria spp. Paramphistomum spp. eggs were first detected from the captive Père David's deer, and Fasciola spp. eggs were first reported from sika deer in zoo in China. A sequence analysis of ITS-2 and cox1 showed that the eggs isolated from the African lion (Panthera leo Linnaeus, 1758) were T. leonina, and the eggs from the brown bear (Ursus arctos Linnaeus, 1758) were B. transfuga. The public health threat posed by these potential zoonotic parasitic agents requires attention. These results lay a theoretical foundation for prevention and control of wild animal parasitic diseases at zoos in China.

Abstract
Introduction Few studies have investigated the occurrence of microeukaryotic gut parasites in dromedary camels in Egypt, and the majority of these investigations are based on microscopic analysis of fecal material. Methods Herein, we assessed the occurrence, molecular diversity, and zoonotic potential of protozoan (Cryptosporidium spp. and Giardia duodenalis) and microsporidian (Enterocytozoon bieneusi) pathogens in individual fecal samples (n = 102) of dromedary camels with (n = 26) and without (n = 76) diarrhea from Aswan Governorate, Upper Egypt. Other factors possibly associated with an increased risk of infection (geographical origin, sex, age, and physical condition) were also analyzed. The SSU rRNA or ITS genes were targeted by molecular (PCR and Sanger sequencing) techniques for pathogen detection and species identification. Results and discussion The most abundant species detected was G. duodenalis (3.9%, 4/102; 95% CI: 1.1-9.7), followed by Cryptosporidium spp. (2.9%, 3/102; 95% CI: 0.6-8.4). All samples tested negative for the presence of E. bieneusi. Sequence analysis data confirmed the presence of zoonotic C. parvum (66.7%, 2/3) and cattle-adapted C. bovis (33.3%, 1/3). These Cryptosporidium isolates, as well as the four Giardia-positive isolates, were unable to be amplified at adequate genotyping markers (Cryptosporidium: gp60; Giardia: gdh, bg, and tpi). Camels younger than 2 years old were significantly more likely to harbor Cryptosporidium infections. This connection was not statistically significant, although two of the three cryptosporidiosis cases were detected in camels with diarrhea. The spread of G. duodenalis infections was unaffected by any risk variables studied. This is the first report of C. parvum and C. bovis in Egyptian camels. The finding of zoonotic C. parvum has public health implications since camels may function as sources of oocyst pollution in the environment and potentially infect livestock and humans. Although preliminary, this study provides useful baseline data on the epidemiology of diarrhea-causing microeukaryotic parasites in Egypt. Further research is required to confirm and expand our findings in other animal populations and geographical regions of the country.

Abstract
Failure of passive transfer is a management concern for all ruminant species, but is not well described in the literature for camel calves. This case series presents four camel calves (Camelus dromedarius and Camelus bactrianus) referred to a North American veterinary teaching hospital for diagnosis and management of failure of passive transfer. Diagnostics utilized included hematology, serum biochemistry, and immunologic methods as described for crias. Management included antimicrobial, anti-inflammatory, and plasma transfusion therapies. Three of the four calves survived to discharge, and common diagnostic practices such as evaluation of total solids, total protein, immunoglobulin G, and sodium sulfite appear to be correlate to passive transfer status in these four calves. Xenotransfusion with llama plasma was well tolerated by two calves, and xenotransfusion with bovine plasma was well tolerated by an additional calf in this study. An additional work is necessary to develop validated breakpoints for diagnosis of passive transfer status in camel calves.

South American camelids (SACs) have become increasingly popular as livestock and companion animals in the Midwestern United States. With increased ownership, postmortem evaluations and samples available for diagnostic assessment are being submitted more frequently to veterinary diagnostic laboratories. We searched archived pathology records at the Wisconsin Veterinary Diagnostic Laboratory (WVDL) between 2009-2019 for SAC cases. Postmortem records from 166 alpacas and 27 llamas were included, with an average of 1.42 diagnoses per animal. The overall average diagnostic rate was 79.8%. Abortion and neonatal cases (fetus to 1-wk-old) had the lowest diagnostic rate (33.3%) and was the only group with a diagnostic rate statistically significantly lower than the average. The most common diagnoses were gastrointestinal parasitism and suboptimal nutritional status or inanition; 78% of cases diagnosed with suboptimal nutritional status were also parasitized. The gastrointestinal parasites identified most frequently were Eimeria sp. and strongyles, especially Nematodirus sp. Our findings may aid allocation of diagnostic resources to better serve regional SAC populations and provide a framework for practitioners who send samples to laboratories for analysis. Submission of whole bodies, euthanized animals, fresh tissue, and inclusion of placental tissues in abortion cases are recommended for optimal diagnostic outcome.
