“…This is a notable and unexpected finding which, to the authors’ knowledge, represents the first time these cells have been reported in ocular cytological specimens from any species. Globule leukocytes are cells 19 , 20 with large, eosinophilic, cytoplasmic granules/globules 21 , 22 , 23 , 24 containing basic proteins, 22 eccentrically located 24 , 25 small round or bilobed nuclei, 23 and a low nuclear‐to‐cytoplasmic ratio. 23 They have been identified in the gastrointestinal, respiratory, urinary, and reproductive tracts of a variety of birds, fish, amphibians, and reptiles, as well as mammals, 26 including humans, pigs, dogs, cats, sheep, cattle, goats, rabbits, mice, and rats.…”

Objective To assess correlations between clinical and cytological features of feline eosinophilic keratoconjunctivitis at the time of cytological diagnosis. Animals Studied Fifteen client‐owned, domestic breed cats (18 eyes) examined between 2007 and 2019. Procedures An electronic search and medical record review of cats diagnosed with feline eosinophilic keratitis or keratoconjunctivitis (FEK) based on clinical examination findings and eosinophils detected on corneal cytology were conducted. Clinical severity was graded using a modified version of a previously validated semiquantitative preclinical ocular toxicology scoring (SPOTS) system. Clinical grades were assigned following review of clinical images and medical record descriptions, and cytological grades were assigned following review of archived corneal cytology slides. Correlations were analyzed for significance using Spearman's rank correlation coefficient. Results Higher total corneal scores correlated with higher total conjunctival scores, but not with total fluorescein scores. Small lymphocyte scores correlated negatively with scores for collagen degeneration or mineralization. Globule leukocytes, a unique cell type not previously described in ocular cytology, were identified in 4 of 18 cytological samples. Higher globule leukocyte scores were correlated with higher scores for mast cells or plasma cells. Specimens with lower eosinophil scores had higher globule leukocyte scores. Conclusions Large variability was detected in the cytological characteristics and clinical features of FEK‐affected cats. This is the first report of globule leukocytes being identified in ocular cytology from any species. The role of globule leukocytes in the etiopathogenesis and progression of FEK remains unknown and warrants further investigation.

“…Glyphosate can decrease beneficial bacteria in the microbiota of the digestive tract (Shehata et al, 2013). Research conducted by Ohfuji (2020), showed that rumen histopathology contained lesions, chronic erosive or ulcerative mucosal lesions as well as inflammatory lesions that showed eosinophil infiltrates in the rumen wall.…”

Herbicides are generally used in the control of weeds in plants. The use of synthetic chemicals such as herbicides is known tohave a negative impact on the environment. This is because the chemicals in the herbicide can kill or poison the organismsthat eat plants that are exposed to these chemicals. Glyphosate is one of the active ingredients of herbicides which is systemic,so it may leave a residue on weeds such as grasses which are usually used as animal feed. The aim of this study is to analyzethe impact of glyphosate residues on changes in the organ tissue of goats (Capra hircus) fed with feed exposed to glyphosatecompounds. The study was conducted using an experimental method with four treatments of glyphosate concentrationincluding control. The treatment consists of four goats with age of 12 months. The results showed that glyphosate treatmentin feed influenced the development and tissue of the goats. The higher the concentration of the residue exposed to the feed,the higher the residual concentration of glyphosate in livestock blood, namely 0.2377 ppm (P1), 0.3118 ppm (P2), and 0.9377ppm (P3), respectively. The results of the observation on livestock organ tissue showed that there was severe damage to theliver and minor damage to the lung, gastric and kidney tissue. The higher the concentration of the residue exposed to thefeed, the higher the residual concentration of glyphosate in livestock blood and causing more damage
