Prevalence of mastitis and its associated risk factors in lactating camels in Northern Egypt.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Dromedary camels are susceptible to mastitis, a multifactorial disease affecting dairy animals worldwide and leading to significant economic losses, particularly due to its subclinical form. However, limited data exist on the prevalence and risk factors associated with lactating camel mastitis in Egypt. Therefore, a cross-sectional study was conducted across three Egyptian governorates to assess the prevalence and identify potential risk factors. A total of 390 lactating camels were examined for both clinical and subclinical mastitis using the California Mastitis Test (CMT). The overall prevalence of mastitis was 38.46% (150/390), comprising 6.4% (25/390) clinical and 32.1% (125/390) subclinical cases. Significant associations (p < 0.05) were observed between mastitis prevalence and factors such as age, lactation stage, tick infestation, milking hygiene, and the presence of udder or teat lesions. The likelihood of mastitis was six times higher in camels older than five years, three times higher during early lactation, twice as high in the presence of tick infestation, twice as high with poor milking hygiene, and three times higher in animals with udder or teat lesions. Among the 600 quarter milk samples obtained from positive animals, mastitis-causing pathogens were isolated from 380 samples (63.3%), while 220 samples (36.7%) showed no bacterial growth. Streptococcus spp. (excluding S. agalactiae) and Escherichia coli were the most prevalent isolates (26.1% and 25%, respectively), whereas S. agalactiae was the least frequent, detected in only 5.5% of the samples. These findings highlight the importance of implementing integrated control measures to reduce mastitis prevalence, enhance camel milk quality, mitigate economic losses, and safeguard public health.
