Background: Candidiasis is a fungal infection that is often caused by Candida albicans (C. albicans) and in a few cases caused by other Candida species. Infection of gastrointestinal tracts including mouth, esophagus and stomach, as well as enteritis and diarrhea are the most common form of the disease in cattle. Clinical findings: In January 2015 reduction in milk production and severe watery diarrhea were observed in a dairy farm located in Varamin city Tehran, Iran. So that 57.1% of cows with high milk production efficiency and 40% of cows with low milk production efficiency involved severe watery diarrhea. Laboratory tests: in clinical examination of affected animals vital signs such as number of breathing, heart rate, as well as the quality and number of ruminal movements were quite normal. No unusual sings were seen in CBC pattern of affected animals. In stool samples of affected animals no viruses or bacteria were detected while specimens were positive for yeast contamination RapID commercial kits used to identify the genus and species of yeast and C. famata was diagnosed as the cause of diarrhea. Final evaluation: Reports of diarrhea caused by fungal pathogens in animals is very low and Candida species, especially C. albicans and C. glabrata are known as the main causes of fungal diarrhea in animals .This study is the first repot about occurrence of C. famata diarrhea in adult cattle. So that C.famata could be considered as one of the potential causes of diarrhea in cattle.

Candida species are a natural component of the intestinal tract microflora, but in favourable conditions they can cause superficial, mucosal, or even systemic candidiasis. Poultry production might be a source of human drug-resistant yeast infections, including Candida spp. The limited data concerning the antifungal susceptibility of poultry Candida isolates prompted us to carry out research to determine the susceptibility of isolates from turkey intestinal tracts. The beak cavity, crop and cloaca were swabbed of 580 turkeys from 58 flocks in western Poland. The susceptibility tests were conducted using the E-test method with amphotericin B, fluconazole, itraconazole, and voriconazole on 52 isolates of C. albicans, C. catenulata, C. glabrata, C. palmioleophila, C. rugosa, C. krusei and C. lusitaniae. All isolates were susceptible to voriconazole. According to the MIC values obtained for amphotericin B and fluconazole, all Candida spp. isolates were classified as susceptible according to the described breakpoints except for C. krusei, which was the only isolate that was amphotericin B-, fluconazole- and itraconazole-resistant. The susceptibility to itraconazole varied: 11 of the Candida isolates were susceptible (21.1%), 29 were dose-dependently susceptible (55.8%), and 12 isolates were resistant (23.1%). There are few resistant strains of Candida in turkeys, and the drug resistance varies. When Candida passes from turkeys to humans, there is a wide range of antifungal treatment options.

2023
A. Balasubramaniam | T.V. Tamilam
Incidence of candidiasis and its ability to be a primary infection in a native chicken flock of 500 birds reared in cage system was reported. Grossly, pseudomembranous growth giving turkey-towel appearance was noticed in dead birds. Crops from affected chicken yielded Candida albicans was confirmed by culture and germ tube production in poultry serum from the crop samples collected from affected birds. Administration of copper sulphate was found to be effective in containing illness and the signs associated with candidiasis in the affected flock.

A male adult crocodile (Crocodylus niloticus) was diagnosed with systemic yeast infection. Histologically, there were extensive areas of necrosis in the lung, which were associated with a diffuse severe lympho-plasmo-histiocytic inflammatory infiltrate, with numerous multinucleated giant cells, and myriads of intralesional pseudo-hyphae and yeast like organisms within distended foveolae. Necrotic foci were also observed in the mucosa of the digestive tract, trachea, tunica intima of arteries, liver, and heart, with a marked inflammatory lympho-histiocytic infiltrate, with large numbers of epithelioid macrophages and giant cells, and intralesional and intravascular pseudo-hyphae and yeast-like organisms. Oval yeast structures with 4 to 6 μm in diameter and 5 to 8 μm thick paralleled-wall pseudo-hyphae were observed in PAS or GMS stained sections. PCR with DNA template extracted from paraffin embedded tissues amplified the D1/D2 domains of the large subunit rRNA gene, which was sequenced and found to be identical to sequences of a new species, isolated from rotting wood in Brazil, of the genus Spencermartinsiella, which its closest relative is Spencermartinsiella cellulosicola.
