Vet Dermatol 2022; 33:378-383. [PMID: 35670652 DOI: 10.1111/vde.13095] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 03/17/2022] [Accepted: 04/11/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Information on acute-phase protein (APP) concentrations in dogs with sarcoptic mange (SM) is scarce. OBJECTIVE To determine the effects of the clinical severity of disease and concomitant pyoderma on serum C-reactive protein (CRP), serum amyloid-A (SAA), haptoglobin (Hp) and ceruloplasmin (Cp) concentrations in dogs with SM. ANIMALS Forty client-owned dogs with SM (INF group) and 10 healthy control dogs (CON group). MATERIALS AND METHODS The INF group was divided into three subgroups; Group 1 (mild/moderate), Group 2 (severe) and Group 3 (severe+pyoderma) according to the extent of skin lesions and the presence of concomitant pyoderma. Serum CRP, SAA, Hp and Cp concentrations of all study groups were measured. RESULTS Serum CRP (P < 0.001), SAA (P < 0.001) and Hp (P = 0.016) concentrations of the INF group were higher than the CON group, with no difference in terms of Cp. A statistical difference was measured between groups 2 and 1 in SAA only. C-reactive protein was found to be significantly higher in dogs with severe SM accompanied by pyoderma (Group 3) when compared with dogs with severe SM (Group 2). The area under the receiver-operating characteristic curves differentiating pyoderma among dogs with severe SM was 0.850 for CRP (P = 0.0001, cut-off value >61.3 mg/L with sensitivity 69.29% and specificity 90.91%). CONCLUSIONS The unique findings in this were that the SAA serum concentrations are related to the severity of SM and that serum CRP concentrations are effective in detecting the presence of pyoderma in dogs with severe SM.

Abstract
Scabies is a parasitic infestation of human and animal skin caused by different strains of the itch mite, Sarcoptes scabiei. The World Health Organization (WHO) has declared scabies in human as a neglected tropical disease, and today over 200 million people worldwide are affected. The two most commonly reported clinical manifestation of the condition are ordinary (OS) and crusted scabies (CS). CS, which can lead to fatal consequences due to secondary bacterial infections, is mostly observed in immunocompromised subjects but can also, although rarely, be detected in immunocompetent individuals. Innate and adaptive immune system components are involved in protection and pathogenesis of scabies, although with some differences between OS and CS. While the cutaneous immune response is dominated by CD4+ T-cells in OS, it is mainly mediated by CD8+ T-cells in CS. The two clinical conditions also differ in CD4+ T-cell-mediated immune responses with mixed TH 1/TH 2 (protective) and TH 2/TH 17 (non-protective) immunoprofiles in OS and CS, respectively. Moreover, the development of CS is associated with early immunosuppression that is followed by deleterious immune response to uncontrolled mite proliferation. However, the immune response to scabies still needs further attention due to inconsistent results in the literature. The aim of this study is to attract more attention to this area by summarizing the current literature on innate and adaptive immune responses triggered against S. scabiei mites.

Quantification of immuno-regulatory cytokine and toll-like receptors gene expression in dogs with generalized demodicosis. Vet Parasitol 2020; 280:109063. [PMID: 32151890 DOI: 10.1016/j.vetpar.2020.109063] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 02/23/2020] [Accepted: 02/24/2020] [Indexed: 02/03/2023]
Abstract
The proliferation of Demodex mites is mainly controlled by host immunity; however, the precised mechanism of host-mite interplay and host immune response in the cutaneous microenvironment of dogs with generalized demodicosis (GD) are not yet established. In the present study, we envisaged the alterations in the expression of toll-like receptors (TLRs) and immuno-regulatory cytokine gene in the skin lesions and peripheral blood mononuclear cells (PBMCs) of dogs with GD. The expression of TLR2, TLR6, IFN-γ, TGF-β and IL-10 genes in the skin lesions and PBMCs of 15 dogs with GD was quantified by qRT-PCR. Compared to healthy dogs, significantly elevated expression of TLR2 (P = 0.048), TGF-β (P = 0.04) and IL-10 (P = 0.012) were found in the PBMCs of dogs with GD. Conversely, there was significantly reduced expression of TLR6 gene (P = 0.021) in the PBMCs of these dogs. The infested dogs also revealed significantly elevated expression of TLR2 gene (P = 0.034) in the skin lesions, while, the expression of the TLR6 gene was found to be significantly (P = 0.004) reduced. Interestingly, significant alterations in TGF-β (P = 0.105) and IL-10 (P = 0.162) genes expression were not observed in the skin lesions of diseased dogs. Our findings suggest that Demodex mites contribute to a different systemic and cutaneous immune response in dogs for their proliferation, and consequently the development of GD. Therefore, Demodex mites might be inducing the immunosuppression through activating the systemic over-expression of immunosuppressive cytokines; however, in the cutaneous lesions, the expression of immunosuppressive cytokines remained unaltered. Both systemic and local over-expression of TLR2 and reduced expression of TLR6 genes might be responsible for the inflammatory signs of canine demodicosis and helping to the mite to escape the host immunity.

Abstract
Overproliferation of Demodex mites in dogs with compromised immunity attributed to the development of canine demodecosis. Whether clinical signs of canine demodecosis are triggered by genetically-mediated specific immunodeficiency in dogs or the Demodex mites induce lesions in hair follicles and result in compromised immunity is yet to be fully explored. To unravel the concealments of immunosuppression in canine demodecosis the present study was aimed to estimate the levels of circulating cytokines, pre- and post-therapy in nine dogs with juvenile-onset generalized demodecosis. At day 60 post-therapy of recommended amitraz rinse, significant (p ≤ 0.02) reduction in circulating IL-10 level was observed compared to its level before the start of the therapy (day 0). However, significant alterations in circulating levels of TNF-α and IFN-γ were not observed in these dogs at day 60 post-therapy as compared to their day 0 levels. A strong positive correlation between circulating level of IL-10 and mites population was observed both on day 0 (r2 = 0.656; p ≤ 0.005) and day 60 post-therapy (r2 = 0.575; p ≤ 0.018). Therefore, our findings suggest that Demodex mites induce immunosuppression in dogs during clinical disease and mites burden seems to be responsible for the development of generalized demodecosis.

Abstract
Scabies is a parasitic disease due to infestation of skin by the burrowing mite Sarcoptes scabiei. Scabies is a major public health problem and endemic in resource poor communities worldwide affecting over 100 million people. Associated bacterial infections cause substantial morbidity, and in severe cases can lead to renal and cardiac diseases. Mite infestation of the skin causes localised cutaneous inflammation, pruritus, skin lesions, and allergic and inflammatory responses are mounted by the host against the mite and its products. Our current understanding of the immune and inflammatory responses associated with the clinical manifestations in scabies is far outweighed by the significant global impact of the disease. This review aims to provide a better understanding of human immune responses to S. scabiei in ordinary and crusted scabies phenotypes.

Abstract
The present study aimed to evaluate the immuno-oxidative patho-biology of lice infestation in goats. Sixty goats were divided into five groups; sucking lice (Linognathus africanus) infested (Group 1, n=12), chewing lice (Bovicola caprae) infested-mild (Group 2, n=12), chewing lice (B. caprae) infested-moderate (Group 3, n=12), chewing lice (B. caprae) infested-severe (Group 4, n=12) and healthy control (Group 5, n=12). To assess the pathological changes, markers of oxidative stress (lipid peroxidation-LPO, reduced glutathione-GSH, superoxide dismutase-SOD, Catalase-CAT and total antioxidant capacity-TAC), the markers of immune status (Tumour necrosis factor alpha- TNF-α, Interleukin-10- IL-10, Transforming growth factor beta 1- TGF-β1, ratios of TNF-α/IL-10 and TNF-α/TGF-β1) and hemato-biochemical status were evaluated. Significant anemia, hypoglycemia, hypoproteinemia and hypoalbuminemia were observed in caprine pediculosis irrespective of the type of lice infested. Remarkably increased oxidative stress was observed in chewing lice infested goats and no significant changes in oxidative stress markers were observed in sucking lice infested goats. TGF-β mediated suppression of Th1 and Th2 immune responses was observed in sucking lice infested goats; whereas, a Th2 cytokine dominant inflammatory response was observed in chewing lice infested goats. From the present study, it may be concluded that sucking lice infestation produces remarkable immunosuppression and chewing lice infestation produces significant oxidative stress and inflammatory responses in goats.

Abstract
Scabies is a parasitic disease, caused by the mite Sarcoptes scabiei, and is considered one of the top 50 epidemic diseases and one the most common human skin disease, worldwide. Allergic dermatitis, including an intense itch, is a common symptom, however diagnosis is difficult and there is currently no effective vaccine. The goal of this study was to examine the immune interaction mechanism of both S. scabiei and infected hosts. mRNA-seq and microRNA-seq were conducted on the S. scabiei mite and on infected and uninfected hosts. We focused on differential expression of unigenes and microRNAs, as well as the real targets of unigenes in enriched immune signaling pathways. S. scabiei enhanced host immune function and decreased metabolism after infection, while the immune response of the host inhibited S. scabiei proliferation and metabolism signaling pathways. Differentially expressed unigenes of S. scabiei were enriched in the JAK-STAT signaling pathway and the Toll-like receptor signaling pathway. The differential expression analysis indicated that microRNAs of S. scabiei and hosts have major roles in regulating immune interactions between parasites and hosts.

Abstract
The sheep scab mite, Psoroptes ovis, is a major problem in the beef cattle industry, especially in Belgian Blue (BB) cattle. This breed is naturally more predisposed to psoroptic mange but reasons for this high susceptibility remain unknown. Different immune responses could be a potential cause; thus in this study, the cutaneous immune response and in vitro cellular immune response after antigen re-stimulation were examined in naturally infested BB. Cytokine production in the skin and in circulating re-stimulated peripheral blood mononuclear cells (PBMC) demonstrated a mixed pro-inflammatory Th2/Th17 profile, with transcription of IL-4, IL-13, IL-6 and IL-17. Strong IL-17 up-regulation in the skin of BB was associated with an influx of eosinophils and other immune cells, potentially leading towards more severe symptoms. Virtually no changes in cutaneous IFN-γ transcription were detected, while there was substantial IFN-γ up-regulation in re-stimulated PBMC from infested and uninfested animals, potentially indicating a role of this pro-inflammatory cytokine in the innate immune response. In Holstein–Friesian (HF) cattle, generally more resistant to P. ovis infection, a largely similar immunologic response was observed. Differences between HF and BB were the lack of cutaneous IL-17 response in infested HF and low transcription levels of IFN-γ and high IL-10 transcription in re-stimulated PBMC from both infested and uninfested animals. Further research is needed to identify potential cell sources and biological functions for these cytokines and to fully unravel the basis of this different breed susceptibility to P. ovis.
