Summary: Parasites play important roles in ecosystems by changing the behavior and population dynamics of their host species and the shape of entire communities. Although birds are well-studied, the infection patterns of endoparasites at the community level are not fully understood.

Summary: Garlic-derived organosulfur compounds, such as PTSO-PTS, exhibit anti-inflammatory effects in macrophages and intestinal epithelial cells. These compounds also regulate gene expression during intestinal infection, suggesting their potential as functional food components for improving gut health.

Summary: Immune defence is crucial for organismal fitness. Theoretical models predict stabilizing selection on quantitative immune traits, but empirical studies observe positive directional selection. This study investigates how selection on immune function varies depending on immune challenge, immune traits and populations in freshwater snails. The results show that immune challenge and specific immune traits determine the selection on snails' immune function. Furthermore, there is low differentiation among populations but high genetic variation within populations of immune traits.

Summary: The study assessed the prevalence of protozoa and helminth infection among school-age children in different ecological zones of La Paz, Bolivia. The overall prevalence of intestinal parasites was 82.2%, with protozoa (80%) being more common than helminths (23.3%). The study revealed the importance of sanitation and deworming programs in reducing parasitic infections among children.

Summary: Parasites play important roles in ecosystems, but their complex interactions and roles remain poorly understood. This study in Sabah, Malaysian Borneo, found that parasite communities differ between nocturnal and diurnal primates, with soil-transmitted helminths being widespread. The findings provide new insights into parasite diversity in primate communities and highlight the need for further research in Asia and beyond.

Summary: In this study, the efficacy of a live Salmonella vaccine followed by a killed Salmonella chitosan nanoparticle (CNP) vaccine booster on the cellular and humoral immunity of broilers was evaluated. The results showed increased levels of anti-Salmonella antibodies in vaccinated birds compared to the control group, as well as decreased S. Enteritidis cecal loads. The CNP vaccine did not have adverse effects on bird's growth performance or immune response.

Summary: The study identified the involvement of matrix metalloproteinases (MMPs) in host responses to helminth infections for the first time. The results demonstrate the delicate balance between parasite clearance and host tissue damage, and the potential cost of improved clearance when continually exposed to parasitic worms.

Summary: Despite the prevalence of disease seasonality, the mechanisms behind the fluctuations in seasonal diseases are still poorly understood; Avian hemosporidiosis is increasingly being used as a model for disease dynamics research, but results are complex and depend on the study's focus and scale.

Summary: Coinfection with parasites is associated with a reduced risk of severe COVID-19 in African patients. Parasite-driven immunomodulatory responses may attenuate the hyper-inflammation associated with severe COVID-19.

Summary: Toxoplasma gondii is an intracellular parasite that can cause severe complications in newborns and immunocompromised individuals. It evokes a strong immune response, but chronic infection persists, possibly due to dysfunctionality of memory CD8 T cell response.

Summary: Despite public health intervention efforts, intestinal parasitic infections remain a major public health problem in developing countries, including Ethiopia. This study aimed to determine the prevalence of these infections in a hospital's emergency laboratory over a six-year period and found that approximately one-third of emergency patients were infected with intestinal parasites.

Summary: Uninfected animals can try to prevent parasitism in various ways, such as behavioral avoidance and physiological changes. However, the impacts of interactions with parasitized conspecifics on uninfected animals' physiology are less studied. Understanding how the disease environment affects animals' physiology, survival, and reproduction is crucial for understanding the population dynamics of parasites.

Summary: Patients with persistent lung disease after COVID-19 discharge exhibit abnormal immune-proteomic profiles in the airways, characterized by elevated levels of proteins associated with cell death, tissue repair, and epithelial injury. The severity of airway dysfunction correlates with increased cytotoxic lymphocyte counts, while more extensive lung abnormalities are associated with elevated B cell numbers and altered monocyte subsets. Long-term follow-up indicates that these abnormalities resolve over time.

Summary: Resistance to ceratomyxosis involves a rapid induction of key immune factors and a tissue response that limits the spread of the parasite and the subsequent tissue damage. This study sheds light on the myxozoan-host dialogue and provides a framework for future studies on infection dynamics of C. shasta and other myxozoans.

Summary: Temperature plays a significant role in shaping the response of a major grape insect pest to a copper-based fungicide. The concentration of copper negatively affects larval development and pupal mass, while exhibiting biphasic curvilinear effects on total phenoloxidase activity. Interaction between copper concentration and temperature impacts larval survival and phenoloxidase activity, potentially influencing pest tolerance and performance.

Summary: This study investigated the plasticity of behavioral and physiological responses of male moths to different sexual audiences before and during mating. Results showed that males adjusted their mating behaviors and spermatophore size based on the perceived risk of sperm competition, and reduced mating duration in the presence of females. However, these adjustments did not have an effect on reproductive performance.

Summary: The last century has witnessed a significant decline in biodiversity, with anthropogenic activities being one of the major drivers. Anthropogenic disturbances can cause chronic stress to wildlife, leading to negative effects on fitness. This study aimed to investigate the effects of anthropogenic elements on Montagu's harrier chicks in sparsely urbanized farmland. The results showed that higher anthropization levels were associated with increased stress hormone levels and lower body condition in females. Nestlings in more anthropized areas or harvested crops also exhibited more developmental stress and altered behaviors. The findings highlight the importance of minimizing disturbances in nesting areas of protected bird species.

Summary: This study found that organic farming has a positive impact on the behavior of passerine birds compared to conventional farming, regardless of species. These findings suggest that observing the behavior of passerine birds can provide valuable insights into the state of the environment and serve as an early warning for specific environmental changes in agricultural areas.

Summary: This article reviews the effects of pesticides on bird physiology, behavior, and life-history traits, highlighting the gaps in current research. The study emphasizes that most research has focused on controlled laboratory conditions and has ignored species differences in sensitivity as well as the multiple exposure pathways in natural environments, which have significant consequences for bird populations and communities.

Summary: This study found that neonicotinoid insecticides, which are widely used worldwide, are harmful to farmland bird species and can have potential toxic effects on the environment. Residues of these pesticides were found in bird species at different trophic levels and life stages. The persistence of neonicotinoids in the environment and their mode of exposure to wildlife are still uncertain.

Summary: Agricultural intensification poses a major threat to biodiversity, particularly for farmland bird specialists like Montagu's harrier. Organic farming systems benefit bird reproductive success and biodiversity through promoting agroecosystem health. This study investigates the effects of organic farming on the life history traits of Montagu's harrier chicks and finds associations between organic farming percentage at a local scale, chick energy metabolism, and ornament coloration.
