İran’da Klinik Olarak Sağlıklı Yük Atlarından İzole Edilen Konjunktival Bakteriyel ve Fungal Ajanlar

Abstract

SummaryThis study was conducted to identify bacterial and fungal isolates of the normal eyes in working horses in Iran. Ninety swabs were taken from the conjunctival sac of 45 clinically healthy horses. Aerobic bacterial and fungal cultures were plated. A total of 9 different bacterial species (3 Gram-positive, 6 Gram-negative) and 7 different fungal species (6 molds, 1 yeast) were recovered. Bacillus spp., Staphylococcus spp. and Klebsiella spp. were the most frequently isolated bacteria. Aspergillus spp. and Penicillium spp. were the most frequently recovered fungi. The microbial species isolated are comparable with studies performed on horses in other areas.

Klinik olarak sağlıklı görünen 45 atın konjunktival kesesinden 90 sürüntü örneği toplandı. Aerobik bakteri ve mantarlar yönünden ekimler yapıldı. 9 farklı bakteri (3 Gram-pozitif, 6 Gram-negatif ) ve 7 farklı mantar türü (6 küf, 1 maya) izole edildi. En fazla izole edilen bakterinin Bacillus spp., Staphylococcus spp. ve Klebsiella spp. olduğu belirlendi. En yaygın izole edilen mantar türlerinin ise Aspergillus spp. ve Penicillium spp. olduğu tespit edildi. Bu mikroorganizmaların farklı ülkelerde yaşayan atlardan izole edilenler ile benzer olduğu anlaşıldı.

Yüksek ve Alçak Rakımın Spor ve Hizmet Atlarındaki Konjunktival Flora Üzerine Etkisi: Kuzeydoğu Anadolu’da (Kars ve Iğdır) Bir Saha Çalışması

“…Of these, in the study carried out by Araghi-Sooreh et al [1] , it is stated that Gram-positive bacteria were detected at the rate of 59.51%, while Bacillus spp. were the most frequently identified species at 27.68%.…”

“…For this reason, our study is thought to contribute to the recording of the normal conjunctival flora of the horses in the region. This study, just like the rest of the literature [1][2][3]6] , came across mostly Grampositive bacteria in terms of the isolated bacteria group. The species of bacteria and fungi taken from the high elevation group for isolation have similar rates of isolation.…”

“…On the other hand, the results obtained from horses at low elevations in especially hot and humid areas revealed that the species and isolation rates of the bacteria and fungi in the conjunctival sac samples of both the sports horse group and the work horse group were quite similar. Yet when the Iğdır region (low elevation) and Kars region (high elevation) are compared, significant differences in fungi species [4,5] and isolation rates become obvious when compared with the literature [1,2] . While Aspergillus spp.…”

“…This resident flora also helps protect eye health by preventing potential pathogens from settling on the eye's surface layers. However, when the ocular defense mechanisms weaken, these members of the normal flora may become pathogenic and cause infection [1][2][3] . The bacterial and fungal flora of normal conjunctiva [4,5] has been studied in many animal species [6][7][8][9][10] .…”

Klinik Olarak Normal Koyunların Konjunktival Kesesinde Mantarların Yaygınlığı

“…In the majority of studies on equine species Aspergillus spp is the most common isolate of the normal conjunctiva [2,[8][9][10] , but in domestic carnivores [3] and ruminants including cattle [3,4] and goats [5] generally Cladosporium spp and Penicillium spp were reported to be predominant. In our study, genus Cladosporium (38.89%) also reported as the most frequent isolates of conjunctiva.…”
