... This may be attributed to the large number of dogs living in shelters and stray dogs examined in these governorates. This result is consistent with a previous study in Ismailia governorate, Egypt, where the prevalence of ectoparasite infestation was 100% among 50 examined stray dogs (Abuzeid, 2015). Two types of dog-chewing lice (Trichodectes canis and H. spiniger) were isolated in two examined dogs from two different governorates (Kafr El-Sheikh and Sharkia for each type, respectively). ...
... There is little doubt that H. spiniger infests marsupials (e.g., kangaroos and wallabies) (Bermúdez and Miranda, 2011). This species was reported in Nile-delta of Egypt in Kafr El-Sheikh governorate in two stray dogs by Sultan and Khalafalla (2014), in Ismailia by Abuzeid (2015), in Damietta governorate by Aboelela et al. (2022). Now we report the isolation of this species at Sharkia governorate, which may indicate the spread of this species to this governorate and the possible emergence of new geographical locations. ...
Background: Skin diseases are usually chronic in nature but not life-threatening. They affect the well-being and pose a threat to the general health of the affected animals. Aim: This study aimed to investigate epidemiological, clinical and therapeutic aspects of ectoparasitic infestations in dogs in a number of Egyptian governorates. Methods: Ninety dogs (58 males and 32 females) aged from one month to eleven years from six Egyptian governorates were clinically examined during the years 2022 and 2023. Skin scraping samples were taken from all examined dogs, and deep ear swab specimens from five dogs suspected to have ear mites were obtained and parasitologically examined. Different ectoparasites were classified according to their morphological features. Twenty dogs were treated in four different patterns of administration of local, systemic, and supportive medications. Results: The prevalence of ectoparasite infestation in examined dogs was 64% (58/90). The majority of ectoparasitic infestations (50/58) were single, while the rest (8/58) were mixed. Ninespecies of ectoparasites of fourtaxa were identified: a tick species (Rhipicephalus sanguineus); which had the highest prevalence among isolated ectoparasites from dogs (29%, 26/90), three flea species (Ctenocephalides canis, Ctenocephalides orientis and Ctenocephalides felis) isolated from 18 out of 90 cases (20%), two types of dog chewing louse species (Trichodectes canis and Heterodoxus spiniger) isolated from 2/90 (2.2%) and three mite species: Demodex canis (18/90, 20%), Sarcoptes scabei var. canis (5/90, 6%) and Otodectes cynotis (2/90, 2.2%). The logistic regression analysis of the potential risk factors associated with the prevalence of ectoparasites in dogs revealed that the age, breed, housing environment, habitat, and season were the significant factors affecting the prevalence of ectoparasites (p<0.05 in contrast dog gender did not have a significant effect. Treated dogs showed variations in recovery times and dogs received ancillary treatment showed rapid skin improvement and hair regrowth. Doramectin was effective against ticks and fleas, but Fluralaner was more effective against Demodex mites. Conclusion: The prevalence of ectoparasites in dogs in Egypt could be considered as high and necessitates efforts toward accurate diagnosis, treatment, and control to reduce their impact on animal and public health.
... Due to the importance of ectoparasites infesting dogs in the transmission of many diseases. Few studies were carried out on ectoparasites infesting dogs in Egypt (Abuzeid, 2015;Aboelela et al., 2022). So, the present study was carried out to identify species of ectoparasites infesting dog, their seasonal prevalence, the effect of dog breed, sex, age, weight, lactation and pregnancy on their prevalence and determination the distribution of ectoparasites on dog body. ...
... Regarding fleas, Ctenocephalides canis was recorded infesting dogs with a prevalence of 51.76% which was higher than C. felis prevalence (48.24%). These results agreed with (Abuzeid, 2015) who proved that the prevalence of C. canis was higher than that of C. felis by 100 % in infested dogs in Egypt. (González et al., 2004) declared that C. canis was the only flea species found on the examined dogs in Argentina, (Klimpel et al., 2010) who showed that C. canis and C. felis infesting dogs with percentage of 39.1% and 17.4%; respectively in Brazil. ...

Moreover, the peak month of ectoparasitic infestation in the current study was recorded in August and this finding agreed with (Shaw et al., 2004) in Germany. ...
... A recent report that identified D. caninum eggs in stools of 4 out of 996 Egyptian children highlights this parasitic zoonoses from dogs in Egypt [70]. In the present study, D. caninum had a high estimated pooled prevalence (25.4%, 20.4-30.4%) in 7675 dogs that had been tested in 22 datasets (Table 8; Figure 4), which could be attributed to the wide dispersal of Ctenocephalides canis, the vector for D. caninum, among populations of stray dogs in Egypt [71]. Although the estimated pooled prevalence for datasets published after 2010 (20.8%) was two-thirds of that for datasets published before 2010 (30.0%), the variation was insignificant (p-value = 0.1588). ...
Since the last survey on gastrointestinal (GIT) parasites infecting dogs in Dakahlia governorate, Egypt, was published 40 years ago, the present study detected various GIT parasites in feces of 78 stray dogs in this governorate. Twenty-one dogs (35.9%) had eggs/oocysts of eight different parasites including Toxocara canis (19.2%), Toxascaris leonina (2.6%), hookworms (1.3%), Taenia species (5.1%), Dipylidium caninum (2.6%), Cystoisospora canis (5.1%), Cystoisospora ohioensis (2.6%), and Neospora caninum-like oocysts (1.3%). These results were combined in various meta-analyses with findings of all published surveys on GIT parasites of dogs in Egypt to underline the potential parasitic zoonoses from dogs in the country. Feces and/or gastrointestinal tracts of 19,807 dogs from various Egyptian governorates, but particularly Cairo, have been microscopically tested in 182 datasets published between 1938 and 2022, revealed during our systematic database search. Toxocara canis, interestingly, displayed a twofold higher pooled prevalence (24.7%) when compared to the published global pooled prevalence for T. canis, indicating that dogs represent a major risk for toxocariasis in humans from Egypt. Dipylidium caninum (25.4%) as well as various Taenia species (17.1%) also displayed high pooled prevalences. On the contrary, lower pooled prevalence was estimated for the most important zoonotic taeniid “Echinococcus granulosus” (2.4%) as well as for hookworms (1.8%) in comparison to what has been published from other countries in the region. Relatively high prevalences were estimated for three protozoa detected in dogs and are common to infect children in Egypt; Cryptosporidium (5.5%), Giardia (7.4%), and Entamoeba histolytica (9.8%). In general, the pooled prevalence estimated for various parasites detected in dogs from Egypt has decreased in the recent years, sometimes by as much as one-fifth, but this great decline is statistically insignificant, which should alert the veterinary and public health authorities to continue their efforts for controlling these parasites in a “One Health” approach.

ARTICLE INFO ABSTRACT Keywords The present study aimed to identify ectoparasites species infesting dogs in Qalyubia governorate, Egypt during the period extended from June 2021 to May 202. For this purpose, 271 dogs belonged to nine species were examined to detect ectoparasites. The results showed that prevalence of ticks species was 98.2% and 1.8% for Rhipicephalus sanguineus and Hyalomma dormedari, respectively. The incidence of fleas species was 48.24% and 51.76% for Ctenocephalides felis and Ctenocephalides canis, respectively. Lice species distribution was 84.46% and 14.5% for Heterodoxus spriniger and Haematopinus species, respectively. The infestation by ticks, fleas, and lice was the highest (40.34, 33.89, and 31.08 %, respectively) in summer season, while the winter season showed the lowest infestation of 7.31, 17.37 and 19.52% for ticks, fleas and lice respectively. Stray dogs had the highest infestation rate (62.5%), and male dogs were slightly higher than females without significance (27.9, and 25.4, respectively). All ages are infested, and the highest age of infestation was 7 month to 1 year (15.86%) while young dogs less than 6 months showed less infestation. Dogs weighed (≥ 25kg) showed higher infestation (24.35%) than other weights. Ectoparasites infestation was (57.57%) in pregnant bitches and (31.25%) in lactating bitches. Also, single and mixed infestation between male and female dogs, fur color, and place where ectoparasites distributed on dogs were calculated. It could be conclud that stray dogs were more susceptible to ectoparasites infestation than dog breeds. Fleas are more common followed by ticks, so control measures must be carried against them in dogs. Dogs Ectoparasites Fleas Lice Prevalence Ticks
... Moskvina and Zhelenznova (2015) mentioned that sex did not cause a significant difference in the prevalence of Otodectes cynotis in canines or felines. Abuzeid (2015) reported that Heterodoxus spiniger showed a significant increase in younger dogs when compared with older ones, while Hippobosca longipennis showed a significant increase in older dogs when compared with younger ones and sex did not affect the prevalence of external parasites. ...
... The most common recorded ectoparasites were ticks (Rhipicephalus sanguineus) and fleas (Ctenocephlides canis). These results were in agreement with those of (Abuzeid, 2015;Saleh et al., 2019;Nguyen et al., 2020). All group cases were admitted with pale mucous membranes, itching, alopecia, weight loss and presence of ticks or fleas on the examined animals (Fig. 1C). ...
The study was performed to assess the common etiopathologies, clinical and haematobiochemical alter-
ations in anemic dogs that were admitted to the teaching veterinary hospital at faculty of veterinary medicine, Cairo
University and private clinics in Cairo and Giza governorates, Egypt. A total number (71 dogs) was included in the
present study. This number comprises 16 apparently healthy dogs and 55 anemic cases. Historical data, clinical and
hematobiochemical investigations were applied on all animals for detection of the definitive common causes of anemia.
Results revealed four main definitive causes of anemia included parvoviral infection (sub-group 1): 20 cases (36% of
diseased cases), ectoparasitic infestation (sub-group 2): 18 cases (32%), malnutrition (sub-group 3): 7 cases (12%) and
hepatic or renal diseases (sub-group 4): 10 cases (18%). The most recorded clinical manifestations in diseased dogs
were pale mucous membranes, tachycardia, tachypnea and low performance. Haematological parameters included
haemoglobin (Hb), total erythrocytic count (TEC) and haematocrit (HCT) revealed significant (P≤0.001) decrease
in all diseased sub-groups compared with apparently healthy group. Serum biochemical parameters showed signifi-
cant increase in alanine amino transferase (ALT) level in sub-groups 1and 4 (P≤0.001), sub-group 2 (P≤0.01), and
sub-group 3 (P≤0.05). Aspartate amino transferase (AST) level showed significant increase in sub-group 4 (P≤0.001),
sub-group 1 (P≤0.01) and sub-group 3 (P≤0.05). Significant decrease among glucose level was recorded in sub-group
1 (P≤0.001) and sub-groups 3 and 4 (P≤0.01). Iron level showed significant decrease in sub-group 1(P≤0.001), sub-
group 3 (P≤0.01) and sub-group 4 (P≤0.05). Copper level decreased significantly in sub-groups 1 and 3 (P≤0.01). Total
protein decreased significantly in sub-groups 1and 3(P≤0.001), sub-group 4 (P≤0.01) and sub-group 2 (P≤0.05). All
results were in comparison with apparently healthy group records. Etiopathological identification of canine anemia in
the light of hematobiochemical status is helpful for further investigations and therapeutic protocol decisions.

Aim: A retrospective study was undertaken to determine the occurrence, and the distribution of the most common clinical conditions of young dogs encountered at the National School of Veterinary Medicine clinic, Tunisia, from September 2012 to July 2013, based on sex, age, breeds, and season variation.
Materials and Methods: A total of 515 cases were examined, and 11 clinical conditions were recorded. Clinical examination was performed. X-ray examination and necropsy were carried out only when needed.
Results: Of the 515, 298 cases (57.86%) were male, while 217 (42.14%) were female. The breed-wise difference in the occurrence of various health problems was statistically significant. Nevertheless, no significant association was found between the occurrence of a disease and age. The commonly found clinical conditions were traumatic injuries (22.72%), ectoparasitic infections (20.58%), and gastroenteritis (13.40%). The occurrence of diseases was the highest (60.19%) in the wet season (September-February) followed by 39.81% in the dry season (March-July).
Conclusion: The current study presents the first recorded data about the major clinical conditions of young dogs in Tunisia. These findings can be used to develop more effective disease management and control strategies.
