Effects of gastrointestinal parasites on fecal glucocorticoids and behaviour in vervet monkeys (Chlorocebus pygerythrus).
PLoS One

Relationships between parasites, host physiology, and behaviours are complex. Parasites can influence host hormonal microenvironment and behaviour through "sickness behaviours" that generally conserve energy. Using a parasite removal experiment, we examined the effects of gastrointestinal parasites on fecal glucocorticoid metabolites (fGC) and behaviours of vervet monkeys (Chlorocebus pygerythrus) at Lake Nabugabo, Uganda.

Here, we present a comprehensive morphological and molecular phylogenetic analysis of sp. (Digenea: Clinostomidae) metacercariae parasitizing two freshwater fish species from Southeast Brazil: (piranha) and (tambuatá). The morphological examination revealed distinct characteristics of metacercariae in each host.

Background: Malaria and HIV are leading causes of death in Africa, including Cameroon. Antiretroviral therapy (ART) is expected to boost immunity and reduce vulnerability to opportunistic infections. Reports on comorbidities including malaria are common in Cameroon.

The success of introduced species often relies on flexible traits, including immune system traits. While theories predict non-natives will have weak defences due to decreased parasite pressure, effective parasite surveillance remains crucial, as infection risk is rarely zero and the evolutionary novelty of infection is elevated in non-native areas. This study examines the relationship between parasite surveillance and cytokine responsiveness in native and non-native house sparrows, hypothesizing that non-natives maintain high pathogen surveillance while avoiding costly inflammation.

Anaplasma species are obligate rickettsial intraerythrocytic pathogens that cause an important tick-borne disease of economic importance in livestock production in many countries. Anaplasma species have been detected from farm animals worldwide, there is a paucity of information on Anaplasma infections in goats from Malaysia. Thus, this study aimed to assess the infection rate and identify Anaplasma species and some selected risk factors in goats across selected districts in Kelantan, Malaysia.
