Gastrointestinal Helminth Parasites of Wild Ungulates In Hirpora Wildlife Sanctuary, Kashmir, India

Parasitic infection represents an emerging threat to wild ungulates and a challenge to their management. Although a lot of work has been carried out on helminth parasitic infestation of domestic ungulates of Kashmir but the data pertaining to this aspect of wild ungulates has being ignored. The study on gastrointestinal helminth parasitic infestation of wild ungulates was carried out during post livestock grazing period (November to May) of 2018/2019 in Hirpora Wildlife sanctuary (HWLS) to fill the gap in the existing literature. During the study fresh faecal samples of musk deer Moschus sp.(n=44) and markhor Capra falconeri (n=41)were collected and examined qualitatively and quantitatively for gastrointestinal helminth parasites. A total of seven helminth parasites were recorded which are arranged in the descending order of their overall prevalence as Haemonchus spp. (44.70%),Nematodirus spp. (40%), Trichuris spp. (37.64%), Strongyloides spp. (34.11%)Trichostrongylus spp. (28.23%),Monieziaspp. (23.52%) and Fasciola spp. (20%). The mean EPG (eggs per gram) of different parasites showed a considerable variation in both the wild ungulates. The highest mean EPGwas that of Haemonchus spp. and the lowest mean EPG was that of Fasciola spp. in both hosts. A statistically significant difference was observed in the mean EPG of different parasites among two wild hosts (t=3.606, p=0.01).

Camel gastrointestinal parasites in southern Algeria

This study aimed to identify gastrointestinal parasites in camels (Camelus dromaderius) in the Laghouat region (southern Algeria). The study was carried out over a 5-month period on a total of 100 dromedaries. Dung samples were analysed using different methods such as flotation, sedimentation, and Ziehel-Neelsen staining for research of the cryptosporidiosis. Data showed an overall infestation rate of 78%, with the presence of the following parasites: Cryptosporidium sp. (60%), Nematodes: Nematodirussp (23%), Strongyloides sp. (4%), Marshallagia sp. (2%), and Cooperiasp (3%), different protozoaires: Eimeria sp. (20%), Neobalantidium sp. (2%), and Balantidium coli, cestodes (6%), Moniezia sp. (3%), Multicips sp. (2%), Diphillobothrium sp. (1%), and trematodes: Fasciola hépatica (4%) and Paramphistomum sp (1%). The results showed a significant influence of study site on the parasitic infestation rate (P=0.039). Other factors (sex, age and clinical aspect) had no significant influence. To conclude, gastrointestinal parasites are a major problem of indigenous camels under traditional husbandry. Therefore, parasite control programmes are recommended to increase the productivity of this useful animal.

Taenia solium in the Anterior Chamber: Surgical Management of a Rare Case of Live Free-Floating Parasite

Ocular cysticercosis is a preventable cause of blindness. It is a parasitic infestation caused by Cysticercus cellulosae—which is the larval form of Taenia solium. In 1829, Soemmering reported the first case of a live anterior chamber cysticercosis. In the following, we report a rare case of a 13-year-old male who presented with a live adult Taenia solium in the anterior chamber without any systemic features and its successful management.

Intensity and Predilection of Helminth Parasites of the Red Snapper (Lutjanus argentimaculatus)

Marine fish, particularly the red snappers, are often exposed to helminth parasitic infestation. As a result of the parasitic infestation, the fish population, the fish weight, and the morphological changes in the fish are shrinking. The present research aimed to find out the intensity and predilection of the helminth ectoparasites over the infection of the red snapper (Lutjanus argentimaculatus) and employed the survey method for this purpose. The sampling was carried out by the purposive sampling technique. The sample obtained consisted of 30 fish, 20% of the total red snapper population of 150 fish reared in the floating net cages of Balai Besar Perikanan Budidaya Laut Lampung. The intensity of the fish infestation by a mixture of Haliotrema epinepheli and Benedenia epinepheli was 132.5 individuals/fish. Neobenedenia girellae and Haliotrema epinepheli infected fish with an intensity of 149.41 individuals/fish. The 66.7% of Benedenia epinepheli had a predilection for the dorsal fin, and 33.3% for the anal fin. In Neobenedenia girellae, 57.1% had a predilection for the body surface, 37.2% for the head surface, and 5.7% for the dorsal fin. In conclusion, all sampled fish were positively infected with helminth ectoparasites, including Neobenedenia girellae, Haliotrema epinepheli, and Benedenia epinepheli.

A study on ectoparasites in Indian Mackerel, Rastrelliger kanagurta (Cuvier, 1817) of Thiruvananthapuram coast, South India

Parasitic infestation in marine fish requires urgent attention, especially those that infect economically important fishes, which affect their aesthetic quality and palatability. Ectoparasites in Indian Mackerel, Rastrelliger kanagurta (Cuvier, 1817), have not been studied well. Morphological and seasonal study of ectoparasites in R. kanagurta from the Thiruvananthapuram coast was conducted during March-August 2018. The study investigated three parasitic groups: Trichodinids, Digenean cysts (Centrocestus Looss, 1899), and Cymothoids (Norileca indica Milne Edwards, 1840 and Nerocila phaiopleura Bleeker, 1857) from R. kanagurta during the present study. Of the 240 fishes examined, the Trichodinids and digeneans showed 100% prevalence on the gill samples. Seasons had no significant effect on trichodinids and digeneans prevalence. However, parasitic Cmothoids fluctuated significantly according to the season. They showed greater prevalence during the pre-monsoon (45%) and least in monsoon (25%) due to environmental parameters like rainfall, salinity, and temperature. Trichodinids parasitized gills of R. kanagurta showed increased mucus production, paleness in the gills, and multifocal whitish areas. The Cymothoid infested fish showed lesions with the erosion of the epidermis and underlying dermis at the site of attachment. The noticeable changes were observed in the gill epithelium due to the encystment of digeneans. The Trichodinid ciliates and Heterophyid digenean cysts (Centrocestus Looss, 1899) are reported for the first time in R. kanagurta.

Analysis of Notifications of Rapid Alert System concerning Parasites in Fishery Products

Fish and fishery products are one of Morocco’s most important export products. Fish parasitism is a natural worldwide phenomenon. Fish parasites have a very wide distribution and are found in both the northern and the southern hemispheres of the globe. The present study aimed to assess parasitic infestation in fishery products by analyzing notifications available in the European rapid alert system for food and feed. The analysis involved 663 notifications registered from 2001 to 2019 on the grounds of parasitic infestation. For Morocco, 651 notifications concerning the different exported food products were analyzed. Among the 663 notifications for the presence of parasites, 161 (24.3%) were border rejections. A total number of 20 countries have been detected with the presence of parasites in their exported fish and fish products. The main fish species concerned with this hazard were Hake (26%), Silver Scabbardfish (10.5%), and Angler (9.3%). In Morocco, among the 651 notifications, 373 concerned with seafood (57.2%). The number of border rejections of fishery products was 220 that is 33.8% of overall notifications. Fish and fish products category are the most concerned with 170 rejections (26.1%), with 64 notifications due to the presence of parasites (37.6%). The Silver Scabbardfish was the species most affected by parasite infestations (23.5%), followed by European Anchovy (12.5%) and Swordfish (10.9%). In conclusion, the nematode Anisakis is the most common parasite in fish infestation while the plerocercoïd larvae of the Cestoda Gymnorhynchus gigas seems to have a predilection to infest the Atlantic Pomfret (Brama brama).

SIMULATION MODEL THE PARASITIC INVASION OF THE COMMON CARP CYPRINUS CARPIO LINNAEUS IN PASTURE AQUACULTURE

The article proposes to consider a dynamic model of parasitic invasion of fish of the family Cyprinidae by a parasite of the genus Bothriocephalus. The model is built in the MAEcoS program and based on the example of a small lake in the south of Western Siberia. The author describes studies of the parasitic infestation of common carp from one to two years old in pasture rearing during one season. The parasite is taken into account in the model by a value proportional to the number of infected fishes and is described by a function with a lagging argument. The transition of uninfected fish to infected fish, mortality and the influence of predators are taken into account. This study was conducted for the first time.
