“…That is, these results suggest that the vaccine effectively reduced the occurrence of pneumonia caused by P. multocida in sheep and goats. In consent to our ndings higher seroprevalence of P. multocida serotype A (60%) was observed in sheep in north Ethiopia 26 and elsewhere in the world such as 83% in Spain 27 and 87.5% in Egypt 28 .…”

Respiratory diseases caused by M. haemolytica and P. multocida have been known to result in a considerable loss due to mortality and reduced production. This study aimed at isolation and identification of M. haemolytica and P. multocida associated with pneumonic pasteurellosis in sheep and goats using bacteriological and molecular techniques. Identification of serotypes of M. haemolytica and P. multocida was done using indirect haemagglutination test (IHAT). The in vitro antimicrobial sensitivity profiles of the M. haemolytica were tested using standard disk diffusion method. A total of 52 and 78 nasal swabs were collected from pneumonic cases for bacterial isolation and identification in Borana and Arsi zone, respectively. Four hundred sera samples were collected for identification of serotypes. The results showed that 17 of 52 (32.69%; 95% CI: 20.33, 47.11) nasal swabs collected from pneumonic animals in Borana yielded positive results for Pasteurella / Mannheimia species, 13 (25.00%; 95% CI: 14.03, 38.95) of which were M. haemolytica. None of the samples yielded P. multocida. Twenty-three of 78 (29.49%; 95% CI: 19.69, 40.89) nasal swabs collected from pneumonic animals yielded positive results for M. haemolytica (17) and P. multocida (6). Secondary biochemical characterization revealed that 14 of the 17 isolates conform to M. haemolytica whereas none of the 6 isolates suspected to be P. mutocida were confirmed. Eleven (84.62%) isolates from Borana and 4 (28.57%) from Arsi were confirmed to be M. haemolytica using PCR targeting the Rpt2 genes. None of the isolates with cultural and morphological features of P. multocida gave positive results by molecular assay. Serological assay identified three serotypes of M. haemolytica namely A1, A2 and A7 almost in all of the samples whereas P. multocida serotype A was detected in 78.75% of the samples. The M. haemolytica isolates tested for susceptibility to antibiotics showed resistance against Bacitracin (83.33%) and Penicillin (50.00%) while were found susceptible to Gentamycin, Chloramphenicol and Sulfamethoxazole (100%) and Tetracycline (83.33%). In conclusion, the results of the present study revealed the association of M. haemolytica with pneumonic pasteurellosis in sheep and goats and can be of use in vaccine development in Ethiopia. Nevertheless, further investigations and continuous monitoring of antimicrobial resistance and appropriate selection and prudent use of antimicrobials in livestock sector are required.

“…We con rmed the exposure of sheep and goats to serotypes of M. hawmolytica considered having higher pathogenicity such as A2 and A1, which were reported to cause mortality in young lambs at feedlots elsewhere in the world 27 . Three serotypes of M. haemolytica namely A1, A2 and A7 are identi ed in samples collected from sheep and goats.…”

“…It was recommended to administer the second dose 4 to 6 weeks after the first vaccination at the age of three weeks, when the risk of disease increased and to repeat the vaccination every six or twelve months, depending on the presence of risk factors for the disease. 3,31,[45][46][47] Although its effectiveness against respiratory system infections in sheep has not been proven, long-acting metaphylactic antibiotics such as oxytetracycline and tilmicosin can be applied. 31…”

Respiratory tract infections, which are common in sheep farming, involve interactions between the host's immune system, pathogenic microorganisms such as viruses, bacteria, parasites and environmental conditions. Respiratory diseases can affect sheep of any age and breed. However, acute bacterial and viral pneumonia is most common in those aged three to twelve months due to decreased maternal antibody titers. Although lower respiratory tract infections initially started as a condition caused by a single agent, many cases progress to a complex disease involving both bacterial and viral components, making the diagnosis of the disease complicated by the emergence of secondary infections. Although the inflammatory reaction that occurs in respiratory infections is part of the normal healing process, an extreme reaction can impair healing and severely damage the airways. It is optimal to limit the inflammatory reaction by removing the harmful agent, isolating the damaged tissue, and controlling this tissue. In cases of death due to acute pneumonia, antibiotic drugs are used to prevent further deaths and to treat the herd. It has been found that NSAIDs reduce the release of toxic peroxide which causes the proliferation of fibroblasts and the deposition of collagen in inflammatory processes associated with the respiratory tract. It had been reported that clinical findings improve more rapidly when NSAIDs (non-steroidal anti-inflammatory drugs) were used together with antibiotics in respiratory system infections. In this review, the importance of using NSAIDs in the respiratory tract infections of sheep has been mentioned.
