Airway Diseases and Occupational Exposures in Poultry Industry Workers: A Comprehensive Review.

Hutson Margaret M, Bailey Kristina L KL

The rapid expansion of the poultry industry has significantly increased the demand for poultry meat and related products due to improvements in efficiency and cost-effectiveness. However, this rapid global commercialization has led to an increase in occupational asthma and chronic obstructive lung disease in poultry workers. Exposure to a complex mixture of organic and inorganic compounds, fumes, microorganisms, and particulate matter found in poultry barns has been linked to airway disease in workers. These airborne contaminants include allergens such as feathers, mites, feed dust, molds, ammonia, and bacterial endotoxins, which contribute to airway inflammation, hypersensitivity, and chronic lung damage. Workers may experience symptoms ranging from wheezing and chest tightness to chronic cough and dyspnea, which can progress to clinically significant respiratory conditions if unrecognized and unmanaged. In attempts to minimize these effects, best practices and strategies to reduce these pollutants are actively being researched and implemented. The role of healthcare providers is pivotal in early identification of at-risk workers, thorough occupational history-taking, appropriate diagnostic evaluation, and tailored management to prevent disease progression and improve outcomes. This review highlights the critical need for ongoing surveillance, preventive measures, and education to protect respiratory health in this vulnerable occupational group.

A hidden risk factor for residual mouth breathing in children after adenotonsillectomy: airborne allergen sensitization.

Zeng Zhilong Z, Gao Ru R, Chen Yu Y, Huang Shasha S et al.

Mouth breathing (MB), a common manifestation of sleep-disordered breathing in children may induce craniofacial developmental abnormalities leading to adenoid facies. Although adenoidectomy and/or tonsillectomy (A&T) represents the primary therapeutic intervention, a substantial proportion of pediatric patients exhibit residual mouth breathing postoperatively. Why a substantial subset of children exhibit residual MB remains a critical clinical question. Among the overlooked explanations for this incomplete recovery may be sensitization to airborne allergens-a hidden determinant of postoperative outcomes. This study sought to define the role of this under-investigated risk factor in the failure to resolve MB following A&T. A retrospective analysis was conducted on a cohort of children who underwent A&T at our hospital from June 2023 to June 2024. Incomplete lip seal during sleep was used as the diagnostic criterion for mouth breathing. Allergic rhinitis and rhinosinusitis symptoms were quantified using the Total Nasal Symptom Score (TNSS). Preoperative serum allergen screening was performed in all cases. Multivariate analyses were employed to assess associations between postoperative mouth breathing resolution and age, gender, BMI, allergen sensitization and TNSS. The study included 502 children. Residual mouth breathing was observed in 39.44% of cases. Atopy to airborne allergens was significantly correlated with surgical outcomes (P = 0.028), with house dust mites (HDM) sensitization exerting particularly strong effects (P = 0.002). Elevated TNSS scores for both allergic rhinitis (correlation coefficient R = 0.249) and rhinosinusitis (correlation coefficient R = 0.290) predicted diminished therapeutic response. Sensitization to airborne allergens, particularly HDM, is significantly associated with adverse mouth breathing resolution following A&T, suggesting it as a hidden associated factor for residual mouth breathing.

Reemergence of Scrub Typhus Associated with Leptotrombidium akamushi Mites and Karp-Like Orientia tsutsugamushi Genotype Bacteria, Japan, 2024-2025.

Ogawa Motohiko M, Takada Nobuhiro N, Katayama Takashi T, Hashimoto Yuki Y et al.

Scrub typhus is a miteborne infectious disease caused by Orientia tsutsugamushi bacteria. In Japan, most cases occur in spring and autumn and are transmitted by Leptotrombidium pallidum and L. scutellare mites; summer scrub typhus, transmitted by L. akamushi mites, is rarely reported. In August 2024, a pregnant woman had scrub typhus develop after attending a fireworks event in Niigata Prefecture, Japan, resulting in fetal death. A Vietnam-related Karp-like O. tsutsugamushi genotype, distinct from the Kato type usually associated with L. akamushi mites, was detected from patient samples. Field investigations at the site of the fireworks event revealed seasonal predominance of L. akamushi mites in summer. We detected O. tsutsugamushi sequences identical to the patient's strain in 3 L. akamushi mite larvae and 1 field mouse, suggesting that L. akamushi mites were the source of human infection. Our findings suggest reemergence of summer scrub typhus associated with infected L. akamushi mites carrying a locally novel genotype.

Elucidating the molecular basis of ATP synthase inhibition: A virtual screening framework for next-gen selective acaricides.

Xu Lin L, Chen Jianqiu J, Cheng Jinhui J, Zhao Mingyu M et al.

The rational design of pesticides that selectively target harmful species while sparing beneficial organisms remains a major challenge in sustainable agriculture. Progress in this field has been limited by an incomplete understanding of the molecular basis of selectivity and the lack of effective strategies to exploit specific targets. Here, we provide direct molecular evidence that naturally occurring polymorphisms in the CV-a subunit of mitochondrial adenosine 5'-triphosphate (ATP) synthase are the primary determinants of differential sensitivity between pest mites and predatory mites. Structural modeling and sequence analysis identified the key functional residues (Leu186 in Tetranychus cinnabarinus and Ala200 in Neoseiulus barkeri) that modulate the binding affinity of the inhibitor. Using these mechanistic insights, we developed a structure-based virtual screening pipeline to identify selective small-molecule inhibitors, including Vepdegestrant (ARV-471) and ICG-001, that exploit binding-site variation to achieve robust species specificity. This target-centric discovery framework not only advances the mechanistic understanding of ATP synthase inhibition but also establishes a scalable strategy for the rational design of environmentally safe and precision-oriented acaricides.

Delayed hatching as a life-history response to intraguild predation: interspecific variation in predatory mites.

Furukawa Takamitsu T, Sato Yukie Y

When and why embryos delay hatching in response to predation risk remains poorly understood, particularly across species experiencing different ecological contexts. Predator-induced hatching plasticity allows embryos to adjust hatching timing in response to predator cues, yet interspecific variation in delayed hatching has rarely been examined. Phytoseiid mites provide a useful system because delayed hatching can be induced by mechanical stimuli mimicking predator attacks, and predation risk from cannibalism and intraguild predation (IGP) in the vulnerable larval stage varies among species according to diet specialisation. We compared delayed hatching responses among four phytoseiid mite species differing in cannibalism and diet specialisation by exposing eggs to mechanical stimulation and recording hatching timing with unstimulated controls. Mechanical stimulation induced stronger delayed hatching responses in Neoseiulus californicus (odds ratio = 5.73) and Neoseiulus cucumeris (odds ratio = 7.83), a weaker response in Phytoseiulus persimilis (odds ratio = 3.11), and no detectable response in Typhlodromus bambusae (odds ratio = 0.99). The magnitude of delayed hatching corresponded to interspecific differences in cannibalism and diet specialisation, suggesting that variation in predation risk associated with intraguild interactions shapes hatching timing strategies. These findings support the hypothesis that delayed hatching is an adaptive life-history response to intraguild predation risk and suggest that interspecific variation in hatching plasticity may have important consequences for predator community dynamics and the establishment success of biological control agents.

Effects of temperature on the development and reproduction of Macrocheles nataliae.

Liu Wenbiao W, Zeng Zhaohua Z, Ji Jie J, Ruan Chuanqing C et al.

Macrocheles nataliae (Acari: Macrochelidae) holds promise as a biological control of soil-inhabiting pests. Temperature is a critical abiotic factor influencing the population dynamics and biocontrol efficacy of predatory mites. However, its effects on the development and reproduction of M. nataliae remain poorly understood. In this study, the effects of five constant temperatures (17, 21, 25, 29, and 33 °C) on the growth, survivorship and reproduction of M. nataliae fed on Carpoglyphus lactis was examined using the age-stage, two-sex life table theory and linear degree-day model. Within the 17-29 °C range, the developmental duration and adult longevity of both female and male M. nataliae decreased gradually with increasing temperature. Although immature mites successfully completed development at 33 °C, adult females failed to reproduce, which indicated that high temperature imposes severe inhibitory effects on reproductive function of M. nataliae. The developmental rates of all life stages were adequately described by the linear degree-day model (R² > 0.90), with lower developmental thresholds ranging from 11.11 to 12.61 °C across different stages. Life table analyses identified 25 °C as the optimal temperature for population performance, producing the maximum net reproductive rate (R0 = 14.98), intrinsic rate of increase (r = 0.15 d-¹), finite rate of increase (λ = 1.16 d-¹) and gross reproductive rate (GRR = 28.1). Females exhibited longer lifespans and higher reproductive values than males under suitable temperatures, and individual life expectancy consistently declined with rising temperature. This study firstly defines the suitable thermal range (17-29 °C), optimal temperature (25 °C), and high-temperature (33 °C) reproductive threshold of M. nataliae. These temperature-response parameters provide fundamental data for the mass rearing of this novel biocontrol mite resource under laboratory conditions, and offer a basis for further evaluation of its potential field performance.
