Studies on parasitic prevalence in pet birds from Punjab, Pakistan / Estudos de prevalência parasítica em pássaros de estimação de Punjab, Paquistão

During this one year study, blood and fecal samples of doves (Zenaida asiatica), ducks (Anas platyrhynchos), pigeons (Columba livia), partridges (Alectoris chukar), turkeys (Meleagris gallopavo) and goose (Chen caerulescens) were collected to assess the parasitic prevalence in these birds. The birds were kept at Avian Conservation and Research Center, Department of Wildlife and Ecology, University of Veterinary and Animal Sciences, Lahore. All these avian species were kept in separate cages and their entire body was inspected on regularly basis to record external parasites. For internal parasites, 100 blood and 100 fecal samples for each species were analyzed. During present study, two species of ectoparasites i.e. fowl ticks (Args persicus) and mite (Dermanyssus gallinae) while 17 species of endoparasites; three from blood and 14 from fecal samples were identified. Prevalence of blood parasites was Plasmodium juxtanucleare 29.3%, Aegyptinella pullorum 15% and Leucoctoyzoon simond 13%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Syngamus trachea with parasitic prevalence of 50%, Capillaria anatis 40%, Capillaria annulata 37.5%, Heterakis gallinarum 28.3%, Ascardia galli 24% and Allodpa suctoria 2%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 12.1% and Prosthogonimus macrorchis 9.1% were also recorded from fecal samples of the birds. Single cestode species Raillietina echinobothrida having parasitic prevalence of 27% and 3 protozoan species i.e. Eimeria maxima having prevalence 20.1%, Histomonas meleagridis 8% and Giardia lamblia 5.3% were recorded. In our recommendation, proper medication and sanitation of the bird's houses and cages is recommended to avoid parasites.

Durante este estudo de um ano, amostras de sangue e fezes de pombos (Zenaida asiatica), patos (Anas platyrhynchos), pombos (Columba livia), perdizes (Alectoris chukar), perus (Meleagris gallopavo) e ganso (Chen caerulescens) foram coletados para avaliar a prevalência de parasitas nessas aves. As aves foram mantidas no Centro de Conservação e Pesquisa de Aves, Departamento de Vida Selvagem e Ecologia, Universidade de Veterinária e Ciências Animais, Lahore. Todas essas espécies de aves foram mantidas em gaiolas separadas e todo o seu corpo foi inspecionado regularmente para registrar parasitas externos. Para parasitas internos, foram analisadas 100 amostras de sangue e 100 amostras fecais de cada espécie. Durante o presente estudo, duas espécies de ectoparasitas, ou seja, carrapatos de aves (Args persicus) e ácaros (Dermanyssus gallinae), enquanto 17 espécies de endoparasitas, três de sangue e 14 de amostras fecais, foram identificadas. Os parasitas sanguíneos prevalentes foram Plasmodium juxtanucleare, 29,3%, Aegyptinella pullorum, 15%, e Leucoctoyzoon simond, 13%. As espécies parasitas registradas em amostras fecais incluíram 6 espécies de nematoides viz. Syngamus traqueia com prevalência parasitária de 50%, Capillaria anatis, 40%, Capillaria annulata, 37,5%, Heterakis gallinarum, 28,3%, Ascardia galli, 24% e Allodpa suctoria, 2%. Da mesma forma, duas espécies de trematódeos viz. Prosthogonimus ovatus com prevalência parasitária de 12,1% e Prosthogonimus macrorchis, 9,1%, também foram registrados nas amostras fecais das aves. Espécies de cestoide único Raillietina echinobothrida com prevalência parasitária de 27% e 3 espécies de protozoários, ou seja, Eimeria maxima tendo prevalência de 20,1%, Histomonas meleagridis, 8%, e Giardia lamblia, 5,3%, foram registradas. Em nossa recomendação, são indicados medicação adequada e saneamento das casas e gaiolas dos pássaros para evitar parasitas.

Ameliorative effects of morel mushroom (Morchella esculenta) against Cadmium-induced reproductive toxicity in adult male rats

Abstract Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (n=5/group), the first group served as the control group, second group was treated with an intraperitoneal (i.p) injection of 1 mg/kg/day of Cd. Third and fourth groups were co-treated with 1 mg/kg/day of Cd (i.p) and 10 and 20 mg/kg/day of morel mushroom extract (orally) respectively. The final 2 groups received oral gavage of 10 and 20 mg/kg/day of morel mushroom extract alone. After treatment for 17 days, the animals were euthanized, and testes and epididymis were dissected out. One testis and epididymis of each animal were processed for histology, while the other testis and epididymis were used for daily sperm production (DSP) and comet assay. Our results showed that Cd and morel mushrooms have no effect on animal weight, but Cd significantly decreases the DSP count and damages the heritable DNA which is reversed in co-treatment groups. Similarly, the histopathological results of testes and epididymis show that morel mushrooms control the damage to these tissues. Whereas the morel mushroom extract alone could enhance the production of testosterone. These results conclude that morel mushrooms not only control the damage done by Cd, but it could also be used as a protection mechanism for heritable DNA damage.

Resumo O cádmio (Cd) é um dos principais tóxicos, que afeta a saúde humana por meio da exposição ocupacional e ambiental. No presente estudo, avaliamos os efeitos protetores dos cogumelos morel contra os danos reprodutivos induzidos pelo Cd em ratos. Para tanto, 30 ratos machos foram divididos em 6 grupos (n = 5 / grupo); o primeiro grupo serviu de controle, o segundo grupo foi tratado com injeção intraperitoneal (i.p) de 1 mg / kg / dia de Cd. O terceiro e o quarto grupos foram cotratados com 1 mg / kg / dia de Cd (i.p) e 10 e 20 mg / kg / dia de extrato de cogumelo morel (por via oral), respectivamente. Os dois grupos finais receberam gavagem oral de 10 e 20 mg / kg / dia de extrato de cogumelo morel sozinho. Após o tratamento por 17 dias, os animais foram sacrificados e os testículos e o epidídimo foram dissecados. Um testículo e epidídimo de cada animal foram processados para histologia, enquanto o outro testículo e epidídimo foram usados para produção diária de esperma (DSP) e ensaio cometa. Nossos resultados mostraram que os cogumelos Cd e morel não têm efeito sobre o peso do animal, mas o Cd diminui significativamente a contagem de DSP e danifica o DNA hereditário, que é revertido em grupos de cotratamento. Da mesma forma, os resultados histopatológicos dos testículos e do epidídimo mostram que os cogumelos morel controlam os danos a esses tecidos. Considerando que o extrato de cogumelo morel sozinho pode aumentar a produção de testosterona. Esses resultados concluem que os cogumelos morel não apenas controlam os danos causados pelo Cd, mas também podem ser usados como um mecanismo de proteção para danos hereditários ao DNA.
