Evaluation of different inflammatory markers during the infection of domestic cats (Felis catus) by Cystoisospora felis (Coccidia: Apicomplexa).

Background: Cystoisospora felis or Isospora felis is a ubiquitous apicomplexan protozoon parasite infecting domestic cats worldwide.

Objectives Of The Study: this study aims to identify the causative agent of diarrhea in cats by determining several elevating stressors caused by these coccidian protozoans with molecular characterization. So, from January 2023 to April 2023, a total of 370 domestic cats were hospitalized at various clinics in the Cairo and Giza Governorates.

Isospora pichororei n. sp. (Chromista: Apicomplexa: Eimeriidae) from rufous-capped spinetails Synallaxis ruficapilla Vieillot, 1819 (Passeriformes: Furnariidae: Synallaxiinae) in South America.

Spinetails are a suboscine passerines of the genus Synallaxis Vieillot, 1818 which have great interest for ornithology, given the wide diversity of 37 species that are distributed throughout the Neotropical region. Despite this wide diversity and distribution, Synallaxis spp. have never been recorded as hosts of coccidian parasites.

A New Isosporan (Apicomplexa: Eimeriidae) from the Pacific Blue-Tailed Skink, Emoia caeruleocauda (Sauria: Scincidae: Eugongylinae), from Guam, U.S. Territory.

Purpose: Nothing is known about coccidians (Apicomplexa: Eimeriidae) from the Pacific blue-tailed skink, Emoia caeruleocauda. Here, we report mensural and morphometric data on a new species of Isospora from E. caeruleocauda from Guam, US Territory.

Correlates of Co-Infection with Coccidiosis and Avian Malaria in House Finches (Haemorhous mexicanus).

Pathogens have traditionally been studied in isolation within host systems; yet in natural settings they frequently coexist. This raises questions about the dynamics of co-infections and how host life-history traits might predict co-infection versus single infection. To address these questions, we investigated the presence of two parasites, a gut parasite (Isospora coccidians) and a blood parasite (Plasmodium spp.

A RETROSPECTIVE ANALYSIS OF MORBIDITY AND MORTALITY IN CAPTIVE BLUE-CROWNED LAUGHING THRUSHES (): 1998-2018.

The blue-crowned laughingthrush (BCLT) () is a species of critically endangered passerine that is part of a Global Species Management Plan and experiences high mortality rates in some collections. Complete necropsy and medical records from 15 European institutions that housed BCLT between 1998 and 2018 were assessed to evaluate morbidity and mortality in the captive population. Medical records for 407 BCLT were received; a total of 191 morbidity events were recorded from 111 individual BCLT.

Unique -associated histologic lesions in white-rumped shama ().

Twenty-one white-rumped shamas (19 necropsied, 2 biopsied) () housed at the San Diego Zoo between 1992 and 2020 were diagnosed with infection based on evaluation of histologic sections. Review of these cases revealed a consistent histologic lesion characterized by nodular aggregates of atypical epithelioid macrophages containing few intracytoplasmic protozoa, with or without lymphocytic infiltrates. Of the 19 necropsied cases, 16 (84%) had systemic lesions variably affecting the liver, spleen, gastrointestinal tract, lung, pancreas, connective tissues, or bone marrow, while all 21 diagnosed cases had skin involvement.

The First Isospora Species (Apicomplexa: Eimeriidae) Described from the Northern Yellow-Shafted Flicker (Colaptes auratus luteus) in Ontario, Canada.

Purpose: Members of the genus Isospora commonly infect a wide variety of wild birds. By combining morphometric and genetic data, we are able to differentiate and describe a new apicomplexan parasite, Isospora picoflavae n. sp.

Cystoisospora belli, liver disease and hypothesis on the life cycle.

Cystoisospora belli causes chronic diarrhoea, acalculous cholecystitis, cholangiopathy and disseminated cystoisosporosis in patients with AIDS. Clinical manifestations and histological stages during C. belli infection in a patient with AIDS and liver disease were described.

Cystoisospora belli infection in an AIDS patient in China: Need for cautious interpretation of mNGS.

Cystoisospora belli (C. belli) is an opportunistic coccidian parasite. This case is the first reported C.

Molecular detection of Cystoisospora belli by single-run polymerase chain reaction in stool samples.

Introduction: Cystoisospora belli (C. belli) is the only pathogenic species of the Cystoisospora genus responsible for severe diarrhea in immunocompromised patients. Most common microscopic method of diagnosis is less sensitive due to intermittent shedding of oocysts.

Antibiotic treatment increases yellowness of carotenoid feather coloration in male greenfinches (Chloris chloris).

Carotenoid plumage coloration is an important sexually selected trait in many bird species. However, the mechanisms ensuring the honesty of signals based on carotenoid pigments remain unclear. It has recently been suggested that intestinal integrity, which is affected by gut parasites and microbiota and influences nutrient absorption and acquisition, mediates the relationship between carotenoid ornamentation and individual quality.

Morphological and molecular characterization of Isospora amphiboluri (Apicomplexa: Eimeriidae), a coccidian parasite, in a central netted dragon (Ctenophorus nuchalis) (De Vis, 1884) in Australia.

An Isospora species, Isospora amphiboluri, originally described by Canon in 1967 and later by McAllister et al. (1995), was isolated from a central netted dragon (Ctenophorus nuchalis) housed at a wildlife rehabilitation centre in Perth, Western Australia. Sporulated oocysts of Isospora amphiboluri (n = 30) are spherical, 24.

Cystoisospora belli infection in a renal transplant recipient: a case report and review of literature.

Cystoisospora belli is a coccidian parasite that causes prolonged watery diarrhea especially among immunocompromised patients. Herein, we report a renal transplant patient who complaints of alternating diarrhea and review of literature related to cystoisosporiasis amongst the transplant recipients.

Morphological and molecular description of a new species of Isospora (Apicomplexa) from a New Holland honeyeater (Phylidonyris novaehollandiae).

A new Isospora species is described from New Holland honeyeaters (Phylidonyris novaehollandiae). Sporulated oocysts (n = 25) were characterised as subspheroidal, 29-32 × 28-31 (29.8 × 29.
