In Brazil, serologic evidence of Orthopoxvirus (OPV) circulation showed positivity around 20% in cattle, humans, monkeys and rodents. Although OPV seropositivity has been described in buffalo herds in southeastern Brazil, no Vaccinia virus (VACV) (member of genus OPV) outbreaks in buffalo herds have been described in this country. This study aimed to investigate the detection of anti-OPV antibodies and to study the OPV genome in Brazilian buffalo herds. Our results demonstrated a high OPV seropositivity in buffalo herds on Marajó Island and molecular data confirmed the circulation of VACV. The geographical isolation conditionmight be a sine qua non condition to explain our results.

The emergence of pandrug-resistant (PDR) and extensive drug-resistant (XDR) methicillin-resistant and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA) isolates from bovine milk samples along with biofilm formation ability and harboring various virulence genes complicates the treatment of bovine mastitis and highlights the serious threat to public health. This study investigated for the first time the frequency, antimicrobial resistance profiles, biofilm-forming ability, virulence factors, spa and staphylococcal cassette chromosome mec (SCCmec) types of MRSA and VRSA isolated from clinical and subclinical bovine mastitis in Egypt. A total of 808 milk samples were collected from each quarter of 202 dairy animals, including 31 buffaloes and 171 cattle.

Brucellosis is a disease that poses a higher risk of transmission to animals and people who have close interactions with them, such as farmers. Therefore, the present study was designed to determine the seroprevalence of bovine brucellosis and associated risk factors in Kasur, Punjab, Pakistan. One hundred pooled milk samples from 100 smallholder mixed herds of cows and buffaloes with a total study population of 425 animals (277 cattle and 148 buffalos) with a range of up to seven animals in each herd were collected and tested through a milk ring test (MRT).

Article Synopsis
  • The study focused on establishing a non-linear growth curve for Nili-Ravi buffalo calves by analyzing monthly weight data from 6,644 calves collected over a decade in Punjab.
  • Using various non-linear models, the researchers determined that the Brody model provided the best fit, optimizing key statistical values for growth curve parameters.
  • The genetic analysis revealed low heritability for growth traits but significant genetic correlations, indicating that factors like asymmetric weight and birth weight were positively correlated, while maturity rate showed a negative correlation with body weights.

The decline of biodiversity is a key topic in public discussions around the globe. These debates have triggered massive efforts to increase protected areas and to safeguard the corridors connecting them. The wildlife corridors dealt with in this article are mainly thought to facilitate the mobility of elephants and some other large herbivores (for example, zebra and buffalo).

The water buffalo () is susceptible to bovine tuberculosis (TB), which receives increased attention in areas where buffalo breeding is prevalent, such as in Southern Italy, especially in the Campania region, where 70% of the buffalo stock is bred. Since 2012, TB testing in buffalo herds has been conducted using the Single Intradermal Test (SIT), with the Comparative Intradermal test (CIT) used in cases of inconclusive results. From 2012 to 2016, the interferon-gamma (IFN-γ) test was occasionally employed experimentally in herds with TB outbreaks to expedite eradication efforts.
