“…Moraxella bovis is known to survive in/on flies [23][24][25][26] and reducing fly burdens is an extremely important part of any IBK control program. A variety of different fly control products and methods of delivery are available and a complete listing of all such products is beyond the scope of this discussion.…”

“…to cause disease are not well understood, however, during efforts to control an outbreak of IBK it is important to consider the role that extrinsic risk factors can play in IBK development. Such factors include exposure to ultraviolet radiation 19,21,22 , flies [23][24][25][26] , Mycoplasma spp infection 17,18 , infectious bovine rhinotracheitis (IBR) virus infection 15,16 , and foreign bodies (dust, plant awns).

Key Points• Effective treatment of pinkeye requires accurate diagnosis• Antibiotic treatment can the shorten healing time• Multiple routes of antibiotic delivery can be effective• Efforts to develop herd preventive strategies must involve considerations of risk factors Video of classical signs of Infectious bovine keratoconjunctivitis accompanies this article. AbstractAs with many livestock diseases, the most successful efforts to control (Infectious bovine keratoconjunctivitis) IBK include multiple facets of disease control including the host, the environment, herd management, and ongoing surveillance even after the immediate crisis has Discussions of IBK control programs with producers should take into consideration all aspects of the disease including the host immune response and reduction of potential risk factors.

Infectious bovine keratoconjunctivitis (IBK) caused by Moraxella bovis is commonly seen in the summer months spread by face flies. This trial investigated the difference in incidence of IBK cases from natural exposure between two groups of animals, one treated with Cypermethrin pour-on preparation (PON, n = 98) and one with Cypermethrin impregnated ear tags (TAG, n = 99). Daily Live Weight Gain (DLWG) difference was investigated between animals with cases and those without and between treatment groups. A randomised positive control study, enrolled 197 animals split into two treatment groups. Cases of IBK and DLWG were recorded over the grazing season (April–November 2018). Fifty-four cases of IBK were recorded. There was no association between the two treatment groups (p = 0.362) and case status. Breed and under 12 months old were significant factors for having a case; (OR 2.3, p = 0.014 and OR 3.5, p < 0.001 respectively). There was no difference in DLWG between animals that had a case and animals that had not (p = 0.739) or between the two treatment groups (p = 0.215). Based on our results, there is no significant difference between PON or TAG preparations in the prevention of IBK. Younger animals and white-faced breeds are significantly more likely to suffer with IBK.

“…Face flies are pests of cattle and horses during the warm months and feed on secretions from the eyes, nostrils and mouth. Muscid flies have been implicated in the transmission of Moraxella bovis and summer mastitis in cattle (Arends et al ., ; Madsen et al ., ) as well as C. pseudotuberculosis in cattle and horses (Braverman et al ., ; Spier et al ., ).…”

Abstract. The objective of this study was to detect Streptococcus equi subspecies equi (S. equi) (Lactobacillales: Streptococcaceae) using quantitative polymerase chain reaction (qPCR) in flies collected from a farm with a documented outbreak of strangles. A total of 1856 face flies [Musca autumnalis (Diptera: Muscidae)] were collected using conventional fly traps. The flies were processed for nucleic acid purification and tested for the presence of S. equi by qPCR. A total of 10/1856 flies (0.54%) tested qPCR‐positive for S. equi. The results may implicate the presence of face flies as a risk factor for the transmission of S. equi and highlight the need to institute proper husbandry measures, biosecurity protocols and fly control in order to reduce the potential for infection in at‐risk horses.
