  • PMID 41633051 (2026, American journal of veterinary research) — *[Paraphrased derived summary — non-Open-Access source.]* In 42 client-owned bearded dragons, oral bacterial β-diversity differed between healthy and dental-disease groups, with Pseudomonas aeruginosa, Devriesea agamarum, Serratia marcescens, and Aspergillus more abundant in diseased animals; fruit consumption significantly altered the oral microbiota, suggesting diet (fruit) promotes oral microbial overgrowth with relevance to husbandry and therapy.

  • PMID 41594463 (2026, Animals : an open access journal from MDPI) — Detection of Viable <i>Nannizziopsis guarroi</i> in Housing Environments Prior to Dermatological Lesion Development in Bearded Dragons (<i>Pogona vitticeps</i>).. Abstract (opening): <i>Nannizziopsis guarroi</i> causes dermatomycosis in lizards and snakes. Little is known about the environment's role in transmission of the fungus. The environments of bearded dragons experimentally inoculated with <i>N. guarroi</i> were cultured weekly to assess the presence of viable <i>N. guarroi</i>. Four of six (4/6, 66.67%) enclosures demonstrated an environmental presence of <i>N. guarroi</i> prior to the observation of clinical lesions in the bearded dragon housed there. The environments were positive for <i>N. guarroi</i> growth 7-28 days prior to lesion development. The environment should be considered as a potential site of infection for naïve reptile hosts and environmental seeding may occur prior to the development of clinical nannizziomycosis in exposed lizards. *[CC BY — Open Access, verbatim with attribution.]*

  • PMID 40958376 (2026, Veterinary ophthalmology) — An Ocular Manifestation of a Systemic Disease With Encephalitozoon Pogonae in a Juvenile Central Bearded Dragon (Pogona vitticeps).. Abstract (opening): <h4>Objective</h4>Encephalitozoon pogonae, a recently identified microsporidian species, has been associated with systemic infections in Central bearded dragons (Pogona vitticeps) manifesting as granulomatous inflammation and vasculitis. Despite the species similarity to Encephalitozoon cuniculi, which causes ocular, neurologic, and renal pathology in rabbits, ocular manifestations of E. pogonae in bearded dragons are underreported. This case report aims to explore the ocular manifestations of E. pogonae in a clinical case and highlight the challenges in diagnosis and treatment of microsporidial infections in reptiles.<h4>Animal studied</h4>A 6-month-old male central bearded dragon with initial presentation of unilateral blepharoconjunctivitis.<h4>Procedures</h4>The patient was treated with topical ofloxacin 0.3% ophthalmic solution, systemic nonsteroidal anti-inflammatories (meloxicam), and antimicrobials (ceftazidime). Diagnostic efforts included physical and ophthalmic examination, ocular high-frequency ultrasound (48 mHz transducer), cytological examination of conjunctiva, and histopathological examination with PCR analysis confirming E. pogonae in both liver and conjunctiva.<h4>Results</h4>Despite treatment, the patient died from hemopericardium. Necropsy demonstrated severe granulomatous inflammation in multiple organs, including the liver, intestines, and ocular structures (conjunctiva and uveal tissue), as well as hypermature cataracts and phacoclastic uveitis, consistent with systemic microsporidiosis.<h4>Conclusions</h4>This case highlights the potential for an ocular manifestation of a systemic disease caused by E. pogonae, underscoring the importance of considering microsporidial infections in the differential diagnosis of refractory ocular disease in reptiles. The findings also emphasize the challenges in diagnosing and treating these infections. *[CC BY — Open Access, verbatim with attribution.]*

  • PMID 42198584 (2026, Pathogens (Basel, Switzerland)) — Pathological, Immunohistochemical, and Bacteriological Characterization of Salmonellosis in Bearded Dragons (&lt;i&gt;Pogona vitticeps&lt;/i&gt;).. Abstract (opening): <i>Salmonella</i> spp. is a major zoonotic pathogen. Although reptiles are mostly considered subclinical carriers, clinical disease may develop following immunosuppression. Clinical salmonellosis in reptiles has been extensively reported; however, the condition has been rarely described in bearded dragons (<i>Pogona vitticeps</i>). We retrospectively analyzed six cases of salmonellosis in bearded dragons and characterized the pathological, immunohistochemical, and bacteriological findings. Clinical signs and gross findings were mostly non-specific. Histological findings mainly consisted of fibrinonecrotizing enterocolitis (83.3%); necrotizing or granulomatous hepatitis (66.7%); pneumonia including bronchopneumonia or interstitial pneumonia in one case each (33.3%); tubulointerstitial nephritis with tubular necrosis (16.7%); and coelomitis (16.7%). <i>Salmonella enterica</i> subsp. <i>houtenae</i> was cultured in three cases (33.3%), whereas <i>S. enterica</i> subsp. <i>enterica</i> serovar Rissen, <i>S. enterica</i> subsp. <i>enterica</i> serovar Cotham, and <i>S. enterica</i> subsp. <i>diarizonae</i> were cultured in one case each. Intralesional bacteria were detected via immunohistochemistry in kidneys and colon in two cases (33.3%). The predominance of lesions in the intestines and liver likely reflects initial intestinal colonization followed by hematogenous dissemination to the liver. Hepatic lesions are thought to represent different stages along a continuum, progressing from acute necrosis to discrete granuloma formation. Renal and respiratory involvement was infrequent, as reported in other reptile species. Some of the isolated <i>Salmonella</i> subspecies (<i>S. diarizonae</i> and <i>S. houtenae</i>) are well-recognized causes of clinical disease in other reptile species but not previously identified in bearded dragons. This study provides a comprehensive pathological, immunohistochemical, and bacteriological characterization of salmonellosis in bearded dragons, thus raising awareness and assisting in the identification of this condition. *[CC BY — Open Access, verbatim with attribution.]*

  • PMID 42017649 (2026, Australian veterinary journal) — *[Paraphrased derived summary — non-Open-Access source.]* A 7-year-old male central bearded dragon (Pogona vitticeps) had an incidental coelomic opacity on routine exam; imaging showed a hepatic cystic lesion, and histopathology after surgical excision confirmed cholangiocarcinoma (pankeratin+, vimentin/α-SMA−), with no metastasis and no recurrence at 10 months — illustrating that early surgical intervention yields favorable long-term outcomes in reptiles.

  • PMID 42345833 (2026, Biology) — Gonadogenesis in the Bearded Dragon (&lt;i&gt;Pogona vitticeps&lt;/i&gt;, Agamidae): A Comprehensive Histological Analysis from Gonadal Ridge Formation to Testicular and Ovarian Development.. Abstract (opening): The bearded dragon (<i>Pogona vitticeps</i>) is the most commonly kept pet lizard and a promising model organism for studies of sex determination and gonadal development. Despite its potential, the morphological basis of gonadogenesis in this species remains poorly characterized. Here, we provide a comprehensive histological characterization of gonad development in <i>P. vitticeps</i> using serial paraffin and semi-thin sections, supplemented by morphometric analyses. Gonadal ridges first appeared at stage S28 as bilateral thickenings of the coelomic epithelium, coinciding with primordial germ cell colonization; by S28/29, a recognizable cortex and medulla were already present. The first morphological differences between male and female gonads appeared at S29/30. In differentiating testes, well-defined testis cords with a central lumen formed rapidly, while the cortex became thin and retained only scattered germ cells. Testicular development was characterized by rapid lumen formation within the testis cords, resulting in their early transformation into seminiferous tubules, followed by elongation and coiling of the tubules, maintenance of a stable tubule diameter, and a transient mitotic arrest of germ cells, with proliferation resuming at stage S36. In differentiating ovaries, the cortex remained thick and multilayered, with a progressive increase in germ cell number reflecting active oogonial proliferation. The ovarian medulla expanded substantially, and from S36 onward, lacunae developed within the medullary cords. No meiotic cells were observed at any examined stage. These results provide an essential morphological framework for future molecular and experimental studies of sex determination and gonadal differentiation in this species and in squamates more broadly. *[CC BY — Open Access, verbatim with attribution.]*

  • PMID 41317138 (2026, Veterinary medicine and science) — Detection of Cryptosporidium and Giardia duodenalis in Reptiles in Thailand.. Abstract (opening): Cryptosporidium spp. and Giardia duodenalis are significant intestinal protozoan parasites affecting humans and animals worldwide. These infections are transmitted through the faecal-oral route, by contaminated water, food or close contact with infected hosts. The zoonotic risk of transmission from reptiles is considered low; yet, limited research exists regarding Cryptosporidium and Giardia infections in these animals. This study investigated the presence of Cryptosporidium spp. and G. duodenalis in reptile faecal samples from a breeding farm in the Chonburi Province, Eastern Thailand. The test population included 363 iguanas, 50 tortoises, 79 bearded dragons and nine snakes. DNA extraction from faecal samples was performed, followed by nested PCR for Cryptosporidium and G. duodenalis, and all positive samples were sequenced for molecular characterisation. Cryptosporidium and G. duodenalis were detected in 13 and 25 out of 501 faecal samples, respectively. Specifically, seven of 363 iguana samples and six of 79 bearded dragon samples tested positive for Cryptosporidium. Cryptosporidium avium was found in 11 samples, and one sample revealed Cryptosporidium serpentis; the remaining sample could not be identified at the species level. For G. duodenalis, 15 of 363 iguanas tested positive, along with six of 79 bearded dragons, two of 50 tortoises and two of nine snakes. Only G. duodenalis assemblage B was identified in positive samples. This study provides epidemiological information on the infection rate and distribution of species of Cryptosporidium and Giardia in a breeding reptile farm in Chonburi Province, Eastern Thailand, and the findings are discussed in the context of the scientific literature. SUMMARY: This study represents one of the largest surveys on Cryptosporidium and Giardia duodenalis in reptiles. Cryptosporidium avium, typically associated with avian hosts, was the predominant Cryptosporidium species identified in iguanas and bearded dragons. Giardia duodenalis assemblage B, known for its zoonotic potential, was the primary assemblage found in iguanas. *[CC BY — Open Access, verbatim with attribution.]*
