Studies on tape worms infesting camels in Behera Governorate, Egypt

Various groups of living and slaughtered camels at Behaira Governorate, Egypt, were investigated for enteric tape worms. The infestation rate was recorded to be 9.5% and 35.6% among living and slaughtered camels, respectively. The detailed identity of the detected worms and its infestation rate was mentioned: Moniezia expansa [17.5%], Moniezia benedeni [16.25%], Stilesia globipunctata [22.5%], and Avitallina centripunctata [1.25%]. The seasonal incidence of the detected tape worms among living and slaughtered camels was denoted

Some studies on fasciola gigantica among naturally infected rabbits in Behera Governorate, Egypt

Fecal samples from 478 Baladi rabbits were examined for the presence of Fasciola gigantica eggs, to clarify its possible role in the epidemiology of this parasite. The seasonal dynamics of F. gigantica among naturally infected rabbits was stated, where the infestation role with this helminth parasite was found to be 16% in autumn, 29.6% in winter, 3.6% in spring and only 2.8% during the summer months. The detected eggs were viable and hatched after 7-9 days at 26C. The hatched miracidia were active and remained alive for 9 hours. Moreover, the pathological changes in the livers of naturally infested rabbits with F. gigantica were also discussed

Ivermectin as antiparasitic agent in goats

Eighty goats 1-2 years old, naturally infested by gastrointestinal parasites were divided into two groups of 40 each. One group was given a subcutaneous injection of ivermectin at the rate of 0.2 mg/kg body weight and the other group was kept as an untreated control. Fecal egg counts and larval cultures were made before treatment, 14 and 30 days post-treatment. Moreover, from each group, three goats were selected and slaughtered 30 days post-treatment. Collected worms were identified and counted. Ivermectin proved to be highly effective on Trihostrongylus axei, Trichostrongylus colubriformis, Haemonchus contortus, Oesophagostomum radiatum and Strongyloides papillosus. Efficacy against Trichuris ovis was lightly lower [83.3%]. Treated animals did not show any symptoms of ill effect during the period of observation

Population dynamics of snail inter mediate hosts of fasciola gigantica in Behera Governorate

It was noted that Lymnaea caillaudi and L. cailaudi var. Alex and rina were only species of Lymnaea snails which were present on Behaira Governorate. The reproduction and propagation of these snails began at the end of summer and beginning of autumn [September and October]. A sharp increase in the number occurred and reached a peak during December through February [the rainy season]. L. caillaudi snails were mainly found at the margins of the drainage channels, small irrigation channels, wide irrigation channels and the margin of the River Nile. The snail population increased when the pH of water ranged between 7.0 to 8.5 and no snails were present at pH 9.0

Control measures against lymnaea caillaudi

The molluscicidal effect of some plants and chemicals on the snail intermediate hosts of Fasciola sp. in Egypt was tried. It was observed that the mortality rate have reached its maximum in the concentration of 10 part per million of copper sulfate after 12 hours and at 1.0 ppm of Bayluscide after 24 hours at room temperature [14 - 23C]. Concerning the effect of plant extracts, it was observed that the leaf infusion of Amaryllis at the concentration of 1: 500 had the mortality rate of 85% after 24 hours, while the bulb infusion was 75%. The infusion of Ambrosia maritima [Damsissa] had a lethal effect of 67.5% at a concentration of 1: 500 after 24 hours. The molluscicidal effect of Typha was 80% after 24 hours, while its rhizomes extracts was 82.5%. In case of and ropogon citratus [lemon grass], the mortality rate was 80% and 47.5% from leaves and rhizomes, respectively, at a concentration of 1: 100 after 24 hours

Survey on the larval trematodes found in the fresh water snails in Edfina Behera Governorate, Egypt

The total percentage of infestation with larval trematodes was 64.5% in Bulinus truncatus, 44.3% in Biomphalaria alex and rina, 27.3% in Melania tuberculata, 19.4% in Lymnaea caillaudi, 16.7% in Physa acuta and 5.5% in Cleopatra spp. The seasonal incidence of cercariae was 65.0% in summer and 11.6% during spring and 0% in winter. The Cercariae, which were shedded from naturally infected fresh water snails in Edfina [Behaira Governorate] were: Xiphidio cercaria from Bulinus truncatus, Nephrostome ramosum cercaria from B. truncatus, Cercaria vivax from Lymnaea caillaudi, Gymnocephala cercaria from Melania tuberculata, Echinostomatidae cercaria from Physa acuta and B. truncatus, Schistosoma mansoni cercaria from Biomphalaria alex and rina, Fasciola gigantica cercaria from Lymnaea caillaudi, Amphistome cercaria from Bulinus truncatus and Cleopatra spp. cercaria tetragl and is from Lymnaea caillaudi

Egyptian hoopoe [iupupa epos major] as a new host for stomaletrema All-Irahimi [Hilmy, 1948]

One of the species belonging to genus Stomaletrema; S. Ali-Ibrahimi [Hilmy, 1948], is described from the Egyptian hoopoe [Upupa epops major], that was hunted from the area of Edfina, Behaira, Egypt. The characters used for its identification are outlined. It is worth to mention that this trematode worm is recorded for the first time infesting the Egyptian hoopoe

Helminths of stray cats in Behera Governorate with special reference to their zoonotic importance

Autopsies of 67 stray cats collected from different localities of Behaira Governorate, Egypt, revealed the presence of endoparasites among all of them [100%]. The cestode parasites were represented by Dipylidium caninum [71.7%], Taenia taeniaeformis [35.8%]. The nematodes were Toxocara cati [29.8%], Trichinella spiralis [8.9%] and Ancylostoma caninum [4.5%], while the recorded trematodes were Heterophyes heterophyes [56.7%], Prohemistomum vivax [19.4%] and Phagicola longicollis [4.5%]. Some cats harbored a single parasite, while others had more than one. Most of these parasites were potentially transmissible to man as a result which indicated that cats could considered from the zoonotic side to be one of the most common reservoirs of many serious parasitic diseases

On heterakis supmaose [Schnider, 1866] recovered from the Egyptian house mouse [Mus musculus]

Heterakis spumosa, a nematode, was recovered from the caecum of two trapped house mice [Mus musculus], from the locality of Edfina, Behaira Governorate, Egypt. The parasite differed from other related species by its distince nephrological characters. Full description of that helminth parasite was given in the text. It is worth to mention that, the house mouse was considered as a new host for Heterakis spumosa worms

Rseudosonsinotrema chameleon [Dolfus, 1951] recovered from the Egyptian chameleons [Chamaeloeo basiliscus]

Autopsies of 16 chamaeleons [Chamaeleo basiliscus], collected from various localities of Behaira Governorate, Egypt, during the summer of 1986, revealed the presence of a trematode belonging to Superfamily Lecithodendriidae, Family Pleurogenetinae, Genus Pseudosonsinotrema and the species Pseudosonsinotrema chamacleonis [Dollfus, 1951]. Full description of that parasite is given. Indeed, that worm is not previously recorded among chamaeleons or any other related hosts in Egypt

Trichinicidal action of ivermectin

The trichinicidal action of the new broad spectrum anthelmintic, Ivermectin, was studied in rats experimentally infected with 100 Trichinella spiralis larvae each. The drug was given subcutaneously at the rate of 0.3 mg/kg b. wt. 2, 7, 14-16 and 21-23 days post infection. The efficiency was found to be 89.4, 91.8, 94.9 and 98.1% on the young intestinal, full developed worms, new encapsulated and encapsulated muscle stages, respectively. The larvae remained in treated rats were surrounded by a defensive tissue reaction and their infectivity was not reduced
