Population genetics of ectoparasitic mites Varroa spp. in Eastern and Western honey bees

open access: yesParasitology, 2019
Host shifts of parasites are often causing devastating effects in the new hosts. The Varroa genus is known for a lineage of Varroa destructor that shifted to the Western honey bee, Apis mellifera, with disastrous effects on wild populations and the ...

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

open access: yesJournal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Prevalence of ectoparasite infestations in owned dogs in Kwara State, Nigeria

open access: yesParasite Epidemiology and Control, 2019
In Nigeria, dogs are the common companions in many households and, harbor wide range of ectoparasites of severe zoonotic potentials. A cross sectional survey was conducted to examine the prevalence, intensity and risk factors of ectoparasite infestation ...

Occurrence of phthirapteran ectoparasite parasitizing on domestic dogs, Canis familiaris (Linne) in Jaunpur district (U.P.) [PDF]

open access: yes, 2013
Only two species of biting louse, Heterodoxus spiniger (Enderlein) (43.27%) and Trichodectes canis (De Geer) (13.47%) have been recorded from 245 dogs examined in twelve different localities in Jaunpur district during 2009 to 2011. Female dogs were found

Parthenogenic hybrid geckos differ from their sexual counterparts in skin microbiomes but not in rates of water loss

open access: yesJournal of Zoology, Volume 327, Issue 2, Page 123-133, October 2025.
Parthenogenic hybrid populations often have differing morphological, physiological, and ecological traits from their parent populations, which alongside clonal reproduction contribute to increased fitness. However, slowed rates of co‐evolution can reduce parthenogens' capacity to outpace parasites, resulting in higher rates of parasitism.

Ectoparasitoses e saúde pública no Brasil: desafios para controle Ecoparasitoses and public health in Brazil: challenges for control

open access: yesCadernos de Saúde Pública, 2003
Doenças ectoparasitárias como a escabiose, a pediculose, a tungíase e a larva migrans cutânea são hiperendêmicas em inúmeras comunidades carentes no Brasil, e não raramente associadas à severidade considerável.

Mate limitation in sea lice infesting wild salmon hosts : the influence of parasite sex ratio and aggregation [PDF]

open access: yes, 2017
Mate limitation in dioecious parasite species has the potential to impact parasite population growth. Our focus of interest was the influence of parasite sex distribution among hosts on parasite reproduction and transmission dynamics for populations of ...

Honey bee predisposition of resistance to ubiquitous mite infestations

open access: yesScientific Reports, 2019
Host-parasite co-evolution history is lacking when parasites switch to novel hosts. This was the case for Western honey bees (Apis mellifera) when the ectoparasitic mite, Varroa destructor, switched hosts from Eastern honey bees (Apis cerana).

Practical Application of Disease Risk Assessment in Native Species Reintroductions: A Case Study of a European Wildcat (Felis silvestris) Population Reinforcement in the Cairngorms National Park

open access: yesMammal Review, Volume 55, Issue 4, October 2025.
Disease risk assessment was conducted for the Saving Wildcats reintroduction project of captive‐bred European Wildcats (Felis silvestris) to the Cairngorms National Park. Hazards were identified, and appropriate pre‐and post‐release mitigation strategies were identified and implemented, illustrating the direct conservation application and significance ...
