Faecal prevalence and histopathological evaluation of coccidiosis in bovine calves.

Bovine coccidiois, caused by Eimeria spp. is widely prevalent around the globe and responsible for huge economic losses by causing morbidity and mortality among young calves. The present study was designed to evaluate the prevalence as well as to evaluate histopathological alterations associated with it. The faecal samples were collected from 700 bovine calves upto two month of age from August 2019 to July 2021 and screened for Eimeria oocycts. The intestinal tissue samples of 37 calves were also collected which died during the study period after showing symptoms of diarrhea and examined for histological lesions. The faecal prevalence of Eimeria observed in our study was 2.29% (16/700) while in tissue samples only two out of 37 were found positive for Eimeria infection. Tissue sections revealed various stages of Eimeria gametogony, variable congestion, haemorrhage, and necrosis along with cryptic dilatation and mononuclear cell infiltration. Coccidia was not found to be associated with season, age and sex of calf. Bovine coccidiosis was found to be endemic with low prevalence but severe onset characterized by moderate to severe congestion and inflammatory reaction mainly in the ileum and caecum.

Psychological consequences of lockdown on dental professionals during the early phase of the COVID-19 pandemic.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2, the virus that causes COVID-19, mainly spreads through respiratory droplets. The dental profession is particularly at risk. Routine dental care was suspended after the announcement of the first lockdown in India. This makes the group vulnerable to psychosocial consequences. The present study aims to evaluate the psychosocial issues among dental professionals during COVID-19 pandemic. MATERIALS AND METHODS: A cross-sectional study was conducted among 627 dental professionals of India, using online Google Forms from April 23, 2020, through April 30, 2020. Participants were evaluated using self-constructed and self-administered personal and professional hardship and fear checklist specifically developed for this study. The 9-item Patient Health Questionnaire (PHQ-9) Depression Scale and 7-item Generalized Anxiety Disorder Scale and PHQ-15 were used to assess the depression, anxiety, and somatic symptoms. RESULTS: Fear had a remarkable impact on 80.7% of responders. Among the participants, 40.5%, 24.5%, and 30.6% reported symptoms of depression, anxiety, and somatic symptoms, respectively. Somatic symptoms were significantly associated with gender (P = 0.000). Work setting was significantly associated with depression (P = 0.011) and anxiety symptoms (P = 0.001). Concern, worry, and fear due to COVID-19 were significantly associated with depression (P = 0.000), anxiety (P = 0.033), and somatic symptoms (P = 0.009). There was a positive correlation between depression and anxiety symptoms (P = 0.01) and between age and somatic symptoms (P = 0.5). CONCLUSIONS: This group reported a high level of depression, anxiety, and somatic symptoms. Female dental professionals and private practitioners had more depression, anxiety, and somatic symptoms. Immediate and special intervention is needed for this group. Further exploration into the nature and its effects of the psychological symptoms may be required.

Cryptosporidiosis in a buffalo calf at Meerut, Uttar Pradesh and its successful therapeutic management.

Cryptosporidium spp. are recognized as one of the most important enteric pathogens causing enteritis and severe diarrhoea in calves up to 1 month of age. Although the infection may be responsible for some mortality, its impact is mainly associated with the impairment of gastrointestinal functions and lower performance of animals. A female buffalo calf of 25 days old was presented to OPD section, College of Veterinary and Animal Sciences, SVPUA&T, Meerut, with the symptoms of severe voluminous watery cholera like diarrhea with mucous and blood tinge since 4-5 days. On physical examination, calf was dehydrated, weak, and emaciated with normal temperature. Parasitological examination of the faeces by the direct smear and modified Ziehl-Neelsen staining technique revealed presence of high number of Cryptosporidium spp. oocysts. The affected female buffalo calf was treated with azithromycin and provided supportive care. Diarrohoeal symptoms were stopped from 3rd day and animal returned to normal condition by 7th day post treatment.
