A Study on Contagious Bovine Pleuropneumonia in Khartoum State, Sudan

Abstract

The study was carried out to investigate the occurrence of contagious bovine pleuropneumonia CBPP in Khartoum state. One-hundred twenty-two pneumonic lung tissue samples were collected from different slaughterhouses (116 samples most of which from local breed cattle) and from the field (six samples from cross breed cattle). Two-hundred and fifty-seven serum samples were collected randomly from cattle in different areas of the state. Tissue samples were cultivated using the standard mycoplasma procedures.Mmm was isolated from three pneumonic lungs collected from the field while no isolates were recovered from slaughterhouse samples. Histopathological sections from the positive samples revealed the typical picture of the CBPP which include fibrinonecrotic pneumonia within filtration of inflammatory cells and fibrin and distention of interlobular septae. One hundred and eight out of 257 serum samples were found positive for antibodies against Mmm using complement fixation test (CFT). Findings of this study confirmed the presence of CBPP in Khartoum state by the isolation and identification of the causative agent.

Sero-Prevalence and Risk factors of Contagious Bovine Pleuropneumonia (CBPP) in Afgoye District Lower Shabelle Region, Somalia

“…Furthermore, this was a statistically significant (0.0001) p < 0.05 of the effect between disease prevalence and breed. As reported in previous studies, European breeds and their crosses are more susceptible to the disease than local African breeds [12]. This study found the highest sero-prevalence of contagious bovine pleuropneumonia in cattle with poor body condition (22.2%) compared to those with medium (11.1%) and good body condition (2.2%).…”

“…Contagious bovine pleuropneumonia transmission occurs through direct and repeated contact between infected and sus-Open Journal of Veterinary Medicine ceptible animals. Inhalation of infective droplets is the main route of infection [12]. This disease is endemic in Africa, although it has been eradicated in other parts of the world through the application of restrictions to the movement of cattle as well as test and slaughter policies combined with compensation for livestock owners during the mid-20th century [13].…”

<b>Avaliação anatomopatológica, imunohistoquímica e molecular da Pleuropneumonia Contagiosa Bovina em animais sacrificados em matadouros no Huambo/Angola</b>

“…Também foram observadas áreas de fibrose, acompanhadas por uma infiltração generalizada de linfócitos e espessamento dos septos interalveolares. Estes achados estão de acordo com a literatura (GIZAW, 2004;KARAM et al, 2005;KOCK et al, 2015), incluindo um estudo com a análise histopatológica em 108 seções de pulmões de animais com a PPCB, confirmados pela sorologia (KARAM et al, 2005).…”

“…Ainda, foi identificado enfisema pulmonar em 34% nos animais do nosso estudo. Apesar de não serem as características clássicas da infecção pelo MmmSC, outros estudos também descrevem esses achados na doença (KARAM et al, 2005;KOCK et al, 2015). Do mesmo modo, observamos que 4% dos animais apresentaram vasculite, característica observada também em infecções experimentais em bovinos (KOCK et al, 2015).…”

“…O animal pode morrer dentro de 10 a 15 dias após os primeiros sinais clínicos se tornarem óbvios. (DONE et al, 1995;KARAM, 2005;PILO et al, 2007). Os septos interlobulares, brônquios e os bronquíolos são rodeados por numerosos linfócitos e plasmócitos (hiperplasia linfoide).…”
