Acute coliform mastitis in buffaloes (Bubalus bubalis): Clinical findings and treatment outcomes

Abstract

This report was delineated to study the clinical, bacteriological and therapeutic aspects concerned with acute coliform mastitis in buffaloes. Bacteriological examination of 80 quarter milk samples obtained aseptically from 56 buffaloes with acute mastitis revealed that coliform bacteria was the most common pathogen (45 cases) followed by Staphylococcus aureus (seven cases) then Streptococcus uberis (three cases), and Streptococcus agalactiae (one case). Clinically, hotness, swelling and painful reaction with serous excretion containing clots was recorded in buffaloes with coliform mastitis. The efficacy of ceftiofur was evaluated in the treatment of buffaloes with acute coliform mastitis. Parenteral ceftiofur neither improved clinical signs nor returned milk to pre-infection production level, whereas intramammary ceftiofur and combination of intramammary with parenteral ceftiofur improved the clinical signs in 10/15 and 12/15 buffaloes, respectively. On quarter level, 3/17, 12/17 and 15/21 quarters recovered in groups received parenteral, intramammary and combination therapy, respectively. This study demonstrates that systemic ceftofur is not effective in the treatment of clinical coliform mastitis in buffaloes.

Characterization of bacterial population of raw milk from bovine mastitis by culture-independent PCR–DGGE method

“…Another interesting observation was that more than one pathogen had been found in some mastitis sample. Similar phenomena have been also reported by the others, Sabry A groups showed that mixed infection by Klebsiella pneumoniae and E.coli was more prevalent than single infection on both animal and quarter level [25],…”

Isolation and characterization ofE. colistrains causing intramammary infections from dairy animals and wild birds

“…Prevalence of coliform infections (Table 2) disagreed with Hawari and Al-Dabbas [52] who detected coliforms in the milk of 31.9% of the mastitic quarters. On the other side, El-Khodery and Osman [53] detected coliforms in 80.36% of the affected buffaloes, but Sayed [54] recorded lower coliform prevalence (21.78%) in the examined milk samples. Escherichia coli was isolated form 7.7% quarter milk samples which is lower than that reported by Verma et al [55] (21.28%).…”

Phenotype characterization of Staphylococcus species strains isolated from buffalo (Bubalus bubalis) milk

“…2 Bacteria isolated with greatest frequency are Staphylococcus aureus, Staphylococcus spp., Bacillus spp., Corynebacterium spp., Escherichia coli, Streptococcus spp., Pseudomonas spp., and Klebsiella spp. 7,9,13 Besides causing mastitis, the genera Staphylococcus are the etiologic agents responsible for approximately 45% of toxin infections worldwide. Contamination can occur by strains of environmental or human origin during the stages of food production or storage; in favorable temperature conditions, the microorganism grows and may produce toxins.…”

“…The most important effect is related to economic losses due to decrease in milk yield. 7 Among the microorganisms responsible for mastitis, bacteria are implicated as the principal etiologic agents. 2 Bacteria isolated with greatest frequency are Staphylococcus aureus, Staphylococcus spp., Bacillus spp., Corynebacterium spp., Escherichia coli, Streptococcus spp., Pseudomonas spp., and Klebsiella spp.…”
