This article is designed to aid the clinician in the diagnosis of bacterial and viral conjunctivitis by evaluating a wide variety of infectious causes of conjunctivitis. The work-up, including techniques of examination and pertinent laboratory studies, is discussed. Clinical features of each type are covered at length and specific therapy for each is included.

This study aimed to identify if sensor technology could be used to detect sickness-type signs (caused by a live vaccine) in laying hens compared to physiological and clinical sign scoring and behaviour observation. The experiment comprised 5 replicate batches (4 hens and 12 days per batch) using previously non-vaccinated hens ( = 20). Hens were moved on day 1 to a large experimental room with various designated zones (e.

The ability to rapidly respond to wildlife health events is essential. However, such events are often unpredictable, especially with anthropogenic disturbances and climate-related environmental changes driving unforeseen threats. Many events also are short-lived and go undocumented, making it difficult to draw on lessons learned from past investigations.

Background: We aimed to determine the household distribution and viability of Chlamydia trachomatis (Ct) from the eyes, face, and hands during the initial two visits of a year-long fortnightly cohort study in geographically defined adjacent households.
Methods/findings: We enrolled 298 individuals from 68 neighbouring households in Shashemene Woreda, Oromia, Ethiopia. All individuals above 2 years of age residing in these households were examined for signs of trachoma.

The aim of this study was to investigate the molecular characteristics and pathogenicity of recently isolated ILTV strains from China, thereby augmenting our understanding of its prevalence. The complete genome sequences of seven ILTV strains obtained from China between 2015 and 2019 were determined by high-throughput sequencing. Phylogenetic analysis showed that six isolates (SD2015, GD2017, SYB2018, HB201812, HB201806, and TJ2019) were classified together with CEO vaccine strains, while only one isolates LN2018 belonged to the wild-type cluster.
